All About The Hydraulic Driven Water Pump
A hydraulic driven water pump is a low-flow water pumping device that works by pumping a small volume of water to a great height. It uses energy in a large volume of water that falls over a short distance. A hydraulic water pump consists of pipes equipped with a drain valve, non-return valve, and pressure vessel. The two valves are the only moving parts of the pump.
The first part or chamber of the pump is equipped with a drain valve. When water enters this chamber, it exits the valve until the pressure in the chamber closes it. The resulting rapid increase in pressure then opens the check valve so that a small amount of water flows out of the supply pipe. This leads to a drop in pressure in the system.
A very simple and inexpensive solution for moving water at a low flow rate is by using a hydraulic-driven water pump. It is ideal for domestic and small agricultural use. The pumps operate using kinetic energy with a large body of water flowing into the pump from a modest height to pump a smaller volume much higher than the source. Hydraulic-driven water pumps are reliable and easy to maintain. Also, they are effective with a 20-foot (6-meter) between the source and the pump, sufficient to pump water to a height of 150 feet at a speed of up to 4000 gallons (15,140 liters) per day.
How hydraulic driven water pump operates:
A hydraulic driven water pump is conceptually very simple: water from a raised source enters the first pump chamber through a drive pipe. This chamber is equipped with a standard drain valve through which water exits. The next section of the hydraulic water pump leads from the first chamber and is isolated from it by a check valve.
When the drain valve closes, the pressure in the chamber rises, opening this check valve and allowing a small amount of water to flow out of the pump through the discharge pipe. When this happens, the pressure in the initial chamber drops, opening the drain valve and repeating the cycle.
The pressure chamber is a vertical tank, partially filled with air, located between the non-return valve and the discharge pipe. When the discharge stream leaves the first chamber, it compresses the air in the vessel, protecting the entire system from a water hammer. Although this vessel increases the efficiency of the pump, it is not essential, and the system will work without it. However, removing the pressure vessel will shorten the life of the entire hydraulic water pump.
Benefits of hydraulic driven water pump
1. Low running costs:
Small size, lightweight, and low water consumption make the operation of hydraulic water pumps economical. The pump has no external rotating parts at all. Compared to pumps of the same capacity, the pumps are smaller.
2. Multiple applications:
Hydraulic-driven water pumps are excellent equipment for daily washing and other jobs where. The pumps are powerful enough, even for industrial applications.
