Hydraulic high pressure electric pump high-pressure electric pump Hengyu hydraulic equipment

140MPA electric pump parameter models of the old model maximum pressure low pressure High flow Low flow power voltage V Haili B3-140 YZB3-140 140MPa 2MPa 0.71L / min 6L / min 3kw 380 Third, the structural principles outlined Haili B Series electric pump from the motor , CFZB series axial piston pump (high pressure pump), low pressure gear pumps, control systems, tanks and other components. 1, series axial piston pump (high pressure pump) The pump is my factory developed the patented product flow valve type axial piston pump, the volumetric efficiency of 90%, driven by the motor of the pump shaft rotation directly, in under the effect of the tilt plate plunger up and down along the plunger reciprocates intercropping, hydraulic oil through the inlet valve suction and discharge from the drain valve, the oil into the system. 2, low-pressure pump to the low-pressure pump gear pump 3, the control valve (1) CZF4M / SC EHV combination valve comprises a high pressure relief valve, a low pressure unloading relief valve, high and low pressure check valve. How it works: low pressure, high pressure pump through the high and low one-way valve at the same time fueling when the working pressure greater than 2.5MPa, the hydraulic control pressure oil low pressure relief valve to open, the low-pressure pump mortar dynamic load back to the oil (low-pressure oil In the case of high-pressure oil does not work also has its own open low pressure overflow valve function. The valve for your safety) (2) 34SZHP 6M pressure hand valve to the median unloading type three-way valve, the assigned rotary piston valve, which is better stain resistance, commutation, reliable, easy maintenance, with packing function. High pressure electric pump installation steps first, during the installation of high pressure electric pump, to prevent debris falling into the machine, so the unit should cover all of the holes, buried on the basis of the unit on the anchor bolts, between the base and the base with a pair of chocks with calibration. Then, to prevent pipeline debris into the high pressure electric pump, installation of the new pipeline, the pump should be fitted with a filter rubber, the effective cross-section should be greater than 2 to 3 times the suction pipe section. Finally, after receiving a good pipeline and determine the motor rotation direction, connect the coupling, and then check it again concentric aromatic shaft. After the actual test run the unit 2 to 3 hours, for a final check, if no adverse phenomenon, it is considered high pressure electric pump installation qualification.
