The hydraulic hand pump is one of the hydraulic pumps, its function is to convert the mechanical energy of the power machine (such as electric motor and internal combustion engine, etc.) into the pressure energy of the liquid. The manual hydraulic pump has advantages of wide range of use, noiseless operation, high security and light weight.
ATO.com online store offers hydraulic hand pump with wide range oil reservoir from 400cc to 3000cc, max output pressure 850 psi/ 10000 psi can be chosen, double acting or single acting available, with high and low pressure two-stage pressure output, optional pressure gauge configuration and oil pipe length. Hand operated hydraulic pump is suitable for flammable and explosive places, the operation process does not produce sparks.
A hydraulic hand pump uses human power as an input to generate a combination of pressure and flow, which then produces hydraulic energy. Based on the simple principle of a handle providing leverage to an internal piston, hydraulic fluid is delivered directly under manually applied pressure. The piston then forces the hydraulic fluid into the cylinder port. Water and hydraulic fluid are the most common fluids, but a variety of pressure media can be used.
The hydraulic pressure generated can be used to provide pressure for testing, adjusting and calibrating different types of measuring instruments or tools. Hydraulic hand pumps are commonly used to load and test mechanical components, especially when the user needs fine adjustments. They are also used in material handling machinery to lift and lower heavy objects, which also requires fine control of the movement of the items.
There are two types of hydraulic hand pumps available:
Single-acting hand pumps apply force only on the downstroke, while double-acting hand pumps apply force on both the downstroke and upstroke. For speed, a double-acting hand pump is the better choice. Not everyone thinks these are the better choice because they are more complicated to maintain and repair if there is a problem. Single-acting hand pumps are simpler and easier to maintain, but they take twice as long to produce the same amount of pressure and movement as double-acting hand pumps.
Single-action pumps are commonly used in hydraulic jacks. Double-acting hand pumps are used in a much wider range of applications. They are used in some aircraft hydraulic systems as a source of hydraulic power in emergencies, to test certain subsystems during preventive maintenance checks, and also to determine the cause of hydraulic system failures. Both types of pumps are designed to reduce operational risk, but double-acting hand pumps are more commonly used to improve safety and minimize downtime.
