YZB series electric pump station consists of motor, CFZB series axial piston pump (high-pressure pump), low-pressure gear pump, control system, oil tank, etc.
1. CFZB series axial piston pump (high pressure pump)
This series of pumps is a patented product valve-type flow axial piston pump independently developed by our factory, with a volumetric efficiency of up to Above 90, the motor directly drives the pump shaft to rotate. Under the action of the tilt plate, the plunger moves up and down along the plunger sleeve. The hydraulic oil is sucked in through the oil inlet valve, discharged from the oil discharge valve, and enters the system oil circuit.
2. Low-pressure pump
The low-pressure pump is a gear pump
3. Control valve
(1) CZF4M/SC ultra-high pressure combination Valves include high pressure safety valves, low pressure unloading relief valves, high and low pressure check valves.
Working principle: When the pressure is low, the high and low pressure pumps supply oil simultaneously through the high and low pressure check valves. When the working pressure is greater than 2.5MPa, the high pressure oil causes the hydraulically controlled low pressure relief valve to open and the low pressure pump moves. No-load oil return (low-pressure oil also has the function of automatically opening the low-pressure relief valve when high-pressure oil does not work. This valve plays a safety role)
(2) 34SZHP 6M ultra-high pressure manual reversing valve is Center position unloading three-position four-way directional valve. This valve is a distribution rotary valve with good pollution resistance, reliable reversal, easy maintenance, and pressure maintaining function.
