In the private sector, it is not always possible to connect to a centralized water supply, so every owner tries to equip a well near the house. At the same time, it is not at all necessary to carry water in buckets. A piston pump can supply it directly to your home.
The principle of operation of the device is quite simple. With some effort, the piston in the cylinder moves up and down. In this case, the thrust is passed through a flange with a rubber seal, which is located on the top cover. A pipe is attached to the bottom of the device, it has a piston. When it is lowered, water is passed upwards through this hole, while the valve at the bottom of the device is closed by water pressure. If the piston begins to rise, then the water that is above it begins to pour out through the outlet pipe. At the same time, the lower valve opens and the liquid is drawn back inside the device.
The piston pump now does everything automatically. It is enough to install it correctly and connect it to the power supply. At the same time, all components of the device must be durable and reliable, especially the inlet tube,through which water is supplied to the pump. Otherwise, the thrust may cause its walls to stick together.
Also, the piston pump must be equipped with check valves strong enough to prevent water from returning back to the inlet hose. They can be membrane or ball. If a round valve is used, it is desirable that it be made of glass, hard rubber, or heavy plastic.
However, you should also take into account the fact that the devices are not designed for a depth of more than 8 meters. If the distance from the surface to the place of occurrence of groundwater is large enough, then a deep pump will have to be installed. The fact is that atmospheric pressure can interfere with the normal operation of the device.
It should be noted that not always a device powered by an electrical network can perform its function without failure. The fact is that from time to time there can be failures in the network. In this case, a manual piston pump can be extremely useful. Although today such devices have not been used for a long time and it is quite difficult to buy them. It will also be useful if you do not plan to spend all the time on the site, you are not going to use water every day.
You can build a piston pump yourself, especially since you can find a lot of device design schemes. However, it is still better to buy the device from a smart manufacturer.
Both at home and on an industrial scale, axial-flow pumps are usedpiston. They are lightweight, small in size, can operate at high speeds, and are easy to install and maintain. The device is unpretentious in use, it can be easily repaired in case of breakage. The only drawback may be its cost, which is often quite high. It can also be used in the hydraulic drive of aircraft, machine tools, bulldozers and other large machines.
