Hydraulic Pliers

Hydraulic clamp by tank, power establishment, reversing valve, pressure relief valve, oil pump body, pump oil from the pump body, high and low pressure oil out of the oil hole, eccentric shaft, eccentric bearing, driven gear and a pair of high pressure oil pump and a low pressure oil pump, oil pump body suspended solid in the cap, high and low pressure oil out of the oil hole opening on the pump body, connected to the oil pressure relief valve, eccentric shaft longitudinally Settings, The upper end is arranged in the center of the oil pump body, the lower end is fixed with eccentric bearings, driven gear is fixed on the top of the eccentric shaft, connected with the power mechanism, high and low pressure oil pump is suspended on the oil pump body, each with an actuator in contact with the eccentric bearing, high and low pressure oil pump cavity respectively with high and low pressure oil outlet hole. The connection between the pumping mechanism and the power mechanism is vertical connection, which can make full use of space and reduce the occupation area, which is conducive to operation and transportation; The pump oil form of high and low pressure oil pump is changed into the action form of eccentric bearing, which has the advantages of simple structure, few parts and convenient assembly.
