Manual hydraulic pump working principle

Hand hydraulic pumps are used more frequently in power, railway, rescue, construction and other fields, such as in field operations, to power construction tools such as cutters, hydraulic pliers and punching machines, fittings, hoses , Valves, pressure vessels, cylinders and other static and blasting test aerospace accessories after maintenance of static and dynamic testing. Understand the manual hydraulic pump working principle for the commencement of work and work efficiency is of great significance. Manual hydraulic pump working principle Manual hydraulic pump working principle is mainly reflected in: the cam driven by the motor rotation, when the plunger to promote upward movement of the plunger, the piston and the cylinder seal to reduce the volume of the formation, the oil squeezed out from the sealed volume , The one-way valve to the place where needed to go. When the cam rotates to the descending part of the curve, the spring forces the plunger down to create a certain degree of vacuum, and the oil in the tank enters the sealed volume under atmospheric pressure. The cam continuously raises and lowers the plunger, periodically reduces and increases the volume of the seal, and the pump continues to suck and drain oil. Manual hydraulic pump safety valve must be calibrated, which can be used in valves and wellhead water bubbling test, pressure regulator testing, brake testing systems, communications cable inflatable equipment. With the increasing use of its products, more and more attention has been paid to accelerate the research on such products. Manual hydraulic pump more years of development, already have a good foundation for the development of such products still have good prospects for development.
