Water pumps for homes and cottages: installation, repair, and home-made circuit unit

Water pumps for homes and cottages

Water - is the main natural wealth. But not everywhere and not always people can connect to the centralized water supply and use of this boon. In such situations, we have to build a stand-alone water supply, for which functionality required pumps. These devices are designed for transporting fluid under pressure. They are widely used, and their variety is pleasantly surprising and at the same time puzzling. Especially pumps needed cottagers and residents of the private sector. Thus, for example, is very popular for water pump house, which pumped water from deep wells and the nearby open bodies of water for watering gardens, because thus avoids many hours of physical labor.

Types and features of pumping equipment

Depending on the conditions under which it will beoperated, the pump can be submerged or superficial. If you have a centralized water supply are often used high-pressure water pumps, which are connected to the water to create a high-pressure jet of water.

Driving surface pump arrangement

Driving surface pump arrangement

All water pumps for home or garden are arranged on one general principle.

During operation the pump creates within itselfvacuum, whereby fluid is drawn from the tank into the vacuum chamber, after which a force is pushed out and the pipe is directed to the destination. Depending on how you create a vacuum distinguish the following principles of action of pumps:

Vortex Pump: pluses and minuses

The operation of these pumps is based on rotationvortex wheels - a flat disc with radial blades on its periphery. During wheel rotation water flows into the cavity within the housing and is pushed out by rotating blades.

The scheme of installation of a submersible pump

disadvantage:

  • Mechanism of the pump is very "do not like" suspended particles that may be in the water.

Therefore, these pumps should be used cautiously when pumping water from contaminated water.

Dignity:

  • High suction capacity and resistance to air bubbles occurring in the "feed" the pipeline.

Electromagnetic (vibration), the pump

The main element - an electromagnet. During feeding on the AC voltage of the electromagnet coil it attracts the armature and the armature returns to its original position when you change the polarity.

Vibrating pump - block diagram

The design of the vibration of the pump

Thus, there is one secondhundred oscillations of the armature. The same vibrating piston associated with the anchor. Since water is an elastic medium, because of the vibrations begin fluctuations and its excesses are pushed into the discharge port through the valve.

Dignity:

  • The absence of rotating elements and the motor.

Reliable and simple centrifugal pump

In this pump when the water impact of the impeller blades centrifugal force occurs, which creates a fluid movement and the necessary pressure.

Centrifugal pump

Centrifugal pump - the embodiment of simplicity and reliability

Such household water pumps produce both submersible and surface types. Centrifugal water pump are available with vertical or horizontal placement of the working shaft.

Hand water pumps

After investing a minimum of means, you can still providehis dacha or garden water. If the demand for water in the area is low or there is no electricity, you can use the manual water pump.

These water pumps are used to give inBasically people who have low incomes and in areas where the electricity supply is carried out with large faults or not at all. In order to bring the device of this type in operation is only required brute human strength. Summer residents use water pumps to irrigate their plots.

Hand pump

Hand Pump - a very common and versatile option

The most common among these modelsa piston pump. The fluid moves the piston under the action of the suction and the pressure difference in the cylinder. In one cycle is fed from 0.5 to 2 liters. The depth with which it is possible to pump water - up to twenty meters.

The second type - vane pump. He has a special blade that is driven by the handle. It is more compact than the piston, but the feed value is below - to 1.5 liters per cycle. But the depth of pumping is the same - to twenty meters.

What pump to choose?

Summarizing all the above, we note that the choice ofpump is totally dependent on the conditions in which it will operate the device. Surface pump select or define an immersion depth of the groundwater. Based on the cleanliness of the pumped fluid is selected vortex or vibration pump. If running water is chronically low blood pressure, there is set the high-pressure water pump does not make sense, it is quite portable pump. It is also very important to keep in mind when working, an electric water pump that communicates directly with water. In most cases, the pumps must have a reliable grounding body and three-pole plug for grounding.

How to make the most water pump

If desired, you can make your water pumphands. It turns out a lot of effort is not necessary for making a simple pump. Schematic representation of the device shown in the figure. This simple pump can pump water from nearby sources. For its production need

  • Corrugated pipe
  • Bracket
  • The sleeve with the valves

The tube is hung to the bracket and a second endis attached to a floating log. On both sides of the pipe sleeves with closed valves. Even small wave motion will in effect a pipe - an accordion. The more will be clenching and unclamping, the better it will work this homemade pump. Note that for gusts of 2 m / sec, in the river undulations begin to swing the pump and pump assist him to twenty-five tons of water per day.

Water pump with his own hands

The device made by his own hand pump

If corrugated pipe made of brass, weightthe logs shall not be less than sixty kilograms. To a homemade pump did not work one day to the lift limiter is attached to a ring through which the bolts are tightened. Limiter with bolt hold-lift in the original position and allow it to be rotated only in a horizontal plane. Bushings are screwed into the terminals and soldered to the corrugated pipe. In a makeshift pump use rubber valves. When the timber is in the correct position, it pulls the pipe and remains strictly perpendicular direction.

Repair of pumps: causes, manifestations fault

Modern features of networks and water supply networks, as well as difficult operating conditions lead to different pumping equipment malfunctions, manifested in the following:

  • Unplanned vibrations of the pump unit;
  • Elevated levels of noise;
  • Rising operating currents;
  • Pulsation;
  • Fall head level;
  • Leakage between the flanges and the shaft of the pump.

If manifests at least one of the above features, it is necessary to repair the water pump.

Among the main causes of failure of the water pump are the following:

  • Errors during installation work unit;
  • Faults electrical installation;
  • Malfunctions of the pump motor;
  • Work on the pump modes, which are different from the regulated.

Since the pump malfunction can cause a lot of reasons, the diagnosis should be carried out by qualified personnel using a variety of instruments and devices.
