How electric hydraulic pump works

Electric hydraulic pumps are relying on the principle of sealed volume changes to the work, it is generally referred to as displacement pump plunger mounted in the cylinder block forming a sealed volume under the action of the spring plunger is always pressed against the eccentric wheel. Prime mover driven eccentric rotation of the plunger reciprocates, so that the size of the sealed volume occurs periodically alternating. When the plunger from small to large, a partial vacuum is formed, so that the oil tank at atmospheric pressure effect, the suction tube to open the top one-way valve into the oil chamber and achieve suction; conversely, when the plunger from big-hour, suction chamber full of oil will top one-way valve opening pressure of the oil flowing into the system implementation. Such pump on the prime mover input mechanical energy into fluid pressure energy, the prime mover driven eccentric constant rotation, the hydraulic pump on the suction and pressure oil continuously.

How torque multiplier works

Torque multiplier is a way to improve the torque device for the operator, it belongs to a torque calibrator, which is composed of a circle or a combination of planetary gears in various combinations of sectors to boost output gear rotates, each class gear torque magnification factor of 5, in a planetary gear system, torque is input and output via the sun gear. Three or four planetary gears and the sun gear is rotated in conjunction. Multiplier within the housing and around the inner circumference of the planetary gear type gear engaged, but the relative rotation of the inner planetary gears, the rotational direction is reversed. Reaction arm prevents the gear integral with the circumferential housing rotation, leaving the planetary gear rotating about a central gear to drive the drive square head rotation, and thus the output torque. If you do not you can not output torque reaction arm.
