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.
