High pressure pump for dirty water. Division by the method of creating a vacuum chamber. Devices with a wet rotor

Water along with air and earth are elements that are probably the most familiar for us, which, we think, does not need to be studied. But this is not so! The powerful magical energy contained in these natural resources is, indeed, amazing. It is necessary to be able to use it for the good of mankind. Plunger Pumps high pressure   - here is a tool for decorating this element. Using them, a person, as if with the help of a magic wand, creates real miracles.

Plunger pumps for water

Interpump Group is a company that works with water and is the world's largest manufacturer of high-pressure plunger pumps. It was founded in 1977, at the initiative of Fulvio Montipo. He made significant technical changes in the design and construction of high-pressure plunger pumps. They introduced radical innovations, thanks to which, produced by the company plunger pumps for water   became more compact, quiet and easy to maintain. Another element of these innovations was the completely ceramic piston group, which provided a higher reliability to the plunger pumps for high pressure washers   , in comparison with the analogues in steel construction. Thanks to this approach, the company Interpump Group, to date, is recognized as the benchmark in its field, producing plunger pumps for water. World leadership is maintained due to quality standards, which guarantees full control over the production process, starting with raw materials ending with the finished product.

Pump for washing

The main part of any high-pressure apparatus is washing pump. Without which, no washing machine can perform its functions. It is the pump for washing that creates the necessary pressure, by means of which water turns into a powerful jet. In the assortment of our company you can find pumps for sinks of different characteristics and, consequently, for different purposes. We can offer you both ready-made solutions for popular ATS, and design stationary washer   High pressure with any characteristics you need.

High pressure washers for washing

All components of the high-pressure pump for washing are made of high-quality materials that are systematically checked and tested at every stage of production. The audit is carried out with the utmost precision, in order to ensure that the final product is resistant to severe wear during operation in industrial conditions, including car washes.

Scope of sump pumps

The company Annovi Reverberi produces high-pressure pumps for car washes with a pressure of 50 bar to 4000 bar, with power consumption up to 750 kW. High-pressure plunger pumps are used to clean most surfaces. Including surfaces of ships and pipelines. And also for cutting and removing concrete, asphalt, paint, cement or metal surfaces. The ultra-high pressure pump is used in the following sectors of heavy industry: construction, ferrous metallurgy, chemical and petrochemical industry, as well as for water purification.

Among other things, high pressure plunger pumps   have proven themselves in the chemical industry. They are used for pumping chemicals, fuel and other corrosive liquids.

(HIGH PRESSURE SUCTION PRESSURE PUMP).

Consider how a high-pressure pump works (HP pump). I think it's right to start with pistons or plungers (call it convenient for you), because they brew all the porridge, namely, moving back and forth, create an alternating pressure on the sign in the compression chambers. When the piston enters the chamber, pressure is created - when it exits, it is discharged. In the movement of the piston are driven by a crank mechanism (I think you know what it is, if not - the Internet to help), which in turn is driven by a motor (electric or internal combustion). So, the piston is drawn in and squeezed out water from the compression chambers (see picture) and water is pumped through the pump. At the output, we get the flow of water to which energy is communicated (see the figure, until you take into account the bypass system, let's consider only the pump).

Now if you attach a hose to the end of which a nozzle with a hole of ø 0.7 mm is attached to the pump, the energy of the water compression will be consumed to overcome the resistance of the nozzle, and a jet of water will be produced under pressure.

So, we looked at the process of the pump without the bypass system. Now consider the operation of the HP pump in general with a bypass system. Water getting into zone A is drawn into the compression chambers and squeezed out into zone B, then into zone C and then to the washing gun with a nozzle, flying out of it with energy, using which the washing process is carried out.

The whole difficulty is that the pump pumped through the entire volume of water per unit of time, to which it is calculated. The nozzle on the actuator (washing gun, or a set of detergent nozzles) is always selected to realize the nominal characteristics of the pump, i.e. the nominal pressure at the nominal flow of water. But pumps are not always used in nominal mode, therefore a bypass is necessary.

Under normal conditions, the pump operates in two modes:

• In pressure mode, bypass operates as a pressure reducing valve (supports constant pressure);


• In the bypass mode.

Let's consider the first case. The water pumped through zone A, compression chamber, zone B, is squeezed out into zone C and to the outlet to the washing nozzle. From zone C to zone B, it has no possibility of a return stroke due to check valve. The bypass valve works as a reduction valve in this case, that is, it maintains a constant water pressure at the outlet, dropping excess water into zone A. With increasing pressure, the water will compress (acting on the bypass piston) spring, thereby opening the valve. The pressure is adjusted by pressing the bypass spring manually, the adjusting cap, the washing operator. The bypass must be adjusted to exclude the operation of the pump with increased pressure.

The second case. When the valve of the cleaning gun is closed, the pressure in the zone C increases to the cutoff pressure, the piston squeezes the spring, thereby completely opening the bypass valve. The water begins to circulate in a circle: zone A - zone B - zone A. The valve remains in this position until the trigger of the detergent gun is pressed because the pressure in the zone C retains the spring in the compressed state. After pressing the trigger of the gun in zone C, the pressure drops to the working level, the spring squeezes the rod and closes the bypass valve, the pressure mode starts.

A high-pressure water pump is an indispensable thing in the face of a lack of natural sources of water resources. If there is no running water or a country house   or the village has the opportunity to independently solve the issue of water supply in conditions of its deficit.

Purpose

A high pressure water pump provides functions similar to a central supply system. A good pressure of liquid from a natural source is produced by the pump system, which operates on different principles.

Power feed mechanisms are popular for several reasons:

Low cost;
  - high performance;
  - a large selection of models for the scope of work, price;
  - easy to use.

Reciprocating and pumping devices will help to ensure the supply of water garden, garden, fill the pool or create an analogue of the water pipe in the house without extra time and effort. It does not require the help of specialists or large financial investments - only compliance with the instructions.

Principle of operation

The high-pressure water pump has general principle   functioning, the same in a variety of models. Classify the supply systems can be based on the different tasks that they perform, by the way of creating a vacuum and the conditions of use. At the time of starting, a vacuum is created inside the mechanism, after which the liquid penetrates into the vacuum chamber, where it is pushed outwards under the influence of pressure.

Types of pump devices

The main types of feed mechanisms presented in the modern market can be the following:

1. Vortex: the creation of a vacuum is provided by rotating a flat disk with vortex blades (a vortex wheel). Blades pushed out the water outside after it hit the body cavity. This device is not harmed by incoming air bubbles, but they can damage suspended particles - because of this, it is necessary to remove dirty water.
2. Vibrational: the role of the pump is played by a magnet on an electrical basis, manipulating the armature and the piston. The created oscillations direct the water into the branch pipes. In this case, there is no electric motor and rotation elements in the structure.
3. Centrifugal Water Pumps   high pressure. These devices are divided into submersible and surface, and also by the method of placing the shaft - horizontal and vertical. In them, the blades of the wheel push water out, creating a certain head.
4. Drainage and circulation: help if necessary heating the house. If the above-mentioned species are water-lifting, the circulation provides a cyclic supply. A distinctive feature is a low need for electricity. Drainage systems will help to remove water after flood or for sewage cleaning, therefore they are made of corrosion-resistant materials.
5. Electric high-pressure water pumps work in conditions where a chopper is required - for crushing large particles that fall during the drainage.

All types of pumps are usually made of quality materials and with varying levels of complexity of the design.

They resist chemical attack and corrosion.

Using Devices

High-pressure water pump for car washes - the most known method   use of these mechanisms. Power feed of the jet provides effective washing of car surfaces.

A high-pressure water pump for a house is an actual solution to the problem of water supply to a country cottage, village, country cottage area. Below we will talk about price categories.

Cost

How much does a high-pressure water pump cost? The price varies depending on the brand's reputation, the country of production, the created pressure of water and the throughput level.

On average, the cost ranges from 50 to 500 dollars. But much depends on the mark-up of a particular store or economic situation. In the absence of competition and the actual time of the year (in case of floods, floods), prices can rise sharply. Therefore, many customers are trying to make a purchase on specialized sites. These stores offer more affordable prices and a much larger selection of models. In general, the cost of construction can be higher because of the availability of automation and high cost of the housing material. The most expensive will be devices made of stainless alloys, cheaper - cast iron and aluminum.

Leading manufacturers

How do experts respond about different brands of pumps? The Danish brand Grundfos, which produces such a product as a high-pressure water pump, since 1945, is recognized as an expert in the production of water supply mechanisms. And today this company produces more than 15 million copies of products a year! The company's competitiveness is based on a narrow specialization and focus on one industry.

Also widely known brand CatPumps, which stands out for high reliability and quality of its devices. Its high-pressure water pump for the home and almost any environment has gained popularity due to its long service life. These mechanisms have a low pulsation, accompanied by the highest possible pressure on the basis of a three-plunger junction.

Inside, there are three pistons that make up this design feature, which ensures a uniform and smooth flow, eliminating 90% of sudden pulsations.

Also known in the market of pump technology are Karcher's products used in water supply, washers and purification plants of industrial facilities. Other manufacturers are followers of these popular brands, including domestic ones, but they lag behind them in different parameters, although they are also quite in demand in their segment.

As you know, without water, and neither there, nor syudy. For residents of holiday villages and not covered by the centralized water supply system of private houses, these are not just words from a song, but a sad reality. And even if there is a water supply in the village, in the summer, life-giving moisture often has to be guarded at night, as there is not enough pressure for everyone in the daytime.

In any case, despair is not necessary. High pressure water pumps installed in the well or installed in the system solve such problems in two counts.

Pumps for individual water supply systems

Regardless of where you get the water - from the well (see), the well or the nearest reservoir - its automatic supply to the site and the house with the optimum pressure can only be provided with a properly selected pump.

Parameters required for selection

You can not go to the store and buy any pump simply because you are satisfied with its appearance or price. It must be selected according to the parameters appropriate to your needs and the source of the water.

These include:

• Performance.   It depends on the amount of water you need, which consists of household and household needs. And calculate it based not on the accepted standards, but on the maximum consumption of all points of water consumption per unit time. In other words, you need to add the number of liters that follow in one minute, for example, from a tap in the kitchen, a shower head and a watering cock in the courtyard, add to it the consumption of the washing machine in order to get the maximum flow, provided they are switched on at the same time. The obtained value will serve as a reference point when choosing an aggregate with the required capacity.

Note. The performance of high-pressure water pumps should not exceed the productivity of a well or well. If the source is emptied faster than replenished, it will cause the equipment to run idle and its failure. How to solve this problem, we will tell just below.

• Head. This is the height in meters, on which the device can lift water. But in order to calculate the required head, it is necessary to take into account the distance of its supply horizontally. According to the simplified formula, it is assumed to be equal to 1/10 of the length of the horizontal line.

Example. To feed water from a well 10 meters deep to the second floor of the house, located at a height of 4 meters from the ground and 12 meters from the well, the minimum pump head is calculated as follows: 10 + 4 + 12/10 = 15.2 m.

In fact, it should be higher, because this formula does not take into account the pressure drop when passing water through pipes, nodes and turns, the diameter of the pipeline and many other indicators. But the most important thing is the required outlet pressure.

And it will be low if the pump you select will have insufficient head pressure. That is why for comfortable use of the water supply system it is necessary to choose a high-pressure water pump - the device of this unit allows to extract water from great depths and supply it to consumers under sufficient pressure.

For reference. For stable operation of water-separating devices and household appliances, the pressure is considered to be not less than 1.5 and not more than 3 bar. Higher values ​​lead to rapid wear of pipes and plumbing fixtures, experiencing increased loads.

Types of high-pressure pumps

The choice of the unit should be based not only on its technical parameters, but also on the design, the ability to work under certain conditions.

The most popular types are:

• Vibration (see).   The principle of operation is based on the ability of a magnet under the action of alternating current   pull to him and release the anchor, connected with the piston. Within one second its position changes several tens times. As a result of such vibration vibrations and pressure changes in the working chamber, water is first sucked into it, and then discharged into the pressure pipeline. The absence of rotating parts makes this type of device reliable and durable.

• Vortex. In the cavity of the body of this unit is a flat disk with radially located blades. Rotating, it displaces the liquid outward. Such pumps have a high suction power and are not afraid of air bubbles in the water. But quickly fail when pumping a dirty liquid with a high content of suspended particles. Therefore, the instruction does not allow their use in wells and sand wells (see).

• Centrifugal (see). Pumped water due to the appearance in the working chamber of the areas of high and rarefied pressure created when the impeller with blades rotates. This is the most common type of pumps that provide high pressure in the network.

All water pumps are classified and by other attributes. For example, there are surface and submersible models   (cm. ).

The first work, being installed outside the source of water, on the surface of the earth. The second ones are immersed in the pumped liquid. They have higher values ​​of pressure and pressure.

Also, water-lifting devices differ in the type of actuation on manual, electric, working on liquid fuel. The most popular ones are electric, operating from 220 V. But there are also models capable of operating from a car battery or other device giving a voltage of 12 V.

Pumps for increasing pressure in a centralized system

If your house is supplied with water from a centralized system, but the pressure in the pipes is not enough for normal operation washing machine   or a shower cabin, it is possible to correct the situation by cutting a water boosting pump into it.

It is installed on the input and either turned on manually when necessary, or equipped with an automatic adjustment system. It turns on the device when the pressure in the network drops and turns off when it is sufficient.

Note. Such units are also suitable for increasing the pressure in an individual water pipe, if the water-lifting pump does not cope with the provision of a normal head.

There is nothing difficult to install a high-pressure water pump with your own hands. To do this, cut the pipe section and weld to the ends of the adapter with a thread.

But this device will be completely useless if the water is simply turned off for a while during the day or if your source has a low production rate and is not able to provide the maximum flow.

In such cases, pumping station   from accumulator tank   - Accumulator. In the period of normal supply, the pump will fill it with water and you can expend it, regardless of whether there is water in the system.

Unfortunately, such a station takes up a lot of space, and during operation it produces a noticeable noise, so installing it in small apartments is problematic. But here everyone decides for himself what is more important for him - silence and spaciousness or normal water supply without interruptions.

Conclusion

Perhaps, this is all that an ordinary consumer should know about high-pressure pumps. Their choice according to the parameters is better still to be entrusted to the specialists, providing them with all available data on the source, water quality, availability of electricity, etc. But, if you want to get more information, watch the video in this article.
