Hydraulic hand pumps are widely used in various industrial applications. The basic purpose of a hydraulic hand pump is to deliver or manually transfer liquids from one place to another. Hydraulic pumps deliver high-pressure fluid flow to the pump outlet. They are powered by mechanical energy sources. To pressurize fluid, hydraulic pumps use gears, vanes, pistons or other devices. A hydraulic pump, when powered by pressurized fluid, can rotate in a reverse direction and act as a motor. Hydraulic hand pumps are widely used for operating jack and cylinders, testing and other purposes.
Features of Hydraulic Hand Pumps
- Hydraulic hand pumps are high in performance and can work in different pressure ranges.
- They have a complete hand operated unit.
- The reservoir size varies depending on the pressure.
- There is a pump operating handle.
- All hydraulic hand pumps have oil level indicator and air breather cum oil filler.
- There are pressure gauze with snubber, needle valves, relief valves in hydraulic hand pumps.
Application and Uses of Hydraulic Hand Pumps
- Hydraulic hand pumps can be used for setting cement retainers where mud or cement pumps are not available.
- Hydraulic hand pumps are used in many different industries, including construction, manufacturing, and military.
- A hydraulic hand pump is used for all varieties of low and high-pressure testing .
- It is used in various other oilfield uses such as removing cores from core barrels; plungers from insert liner pumps, testing valves, fittings, tubing and casing etc.
- It acts as an actuator for hydraulically controlled valves and hydraulically operated systems.
- Hydraulic hand pumps can also be used to calibrate instruments. They use manual power to pressurize the hydraulic systems used in machinery.
- Hydraulic hand pumps can be used for pressure testing in various components like hoses, valves, pipes, heat exchangers, and sprinkler systems.
Operating Mechanism of Hydraulic Hand Pumps
The operation of hand pumps is very simple. Each hydraulic hand pump contains a handle attached to the pump body. This handle when pulled and pushed activates the hydraulic cylinder. This action supplies power to the mechanism to which it is connected
