The characteristic of product:
This variable type of PCY hydraulic axial constant pressure variable pump output pressure is less than it is set constant pressure, the total emissions output pressure oil, the quantitative output, the output oil pressure to adjust set pressure, the PCYpump automatically adjust the pump flow to maintain the constant pressure to meet the system requirements. Constant pressure pump output value, according to the needs of the regulator within the stepless adjustment can be set. The structure of the output pressure oil also passes to the variable piston chamber and the constant pressure valve under the control of oil imports, it is set when the output pressure is less than constant pressure, the role of the constant pressure on the hydraulic spool Thrust spring force is less than it is set, constant pressure valve is turned on, the pressure oil into the piston chamber variable, the variable pressure in the lowest position of the piston, the pump output pressure of the whole oil displacement.
When the PCY hydraulic axial constant pressure variable pumppressure of work in which it is set, the role of the constant pressure valve on the hydraulic thrust is equal to having a set spring force, constant pressure valve into the oil discharge port is turned on at the same time, so that the upper and lower chamber of the hydraulic piston variable equal thrust, variable piston position in a balance of work, if the hydraulic damping (load) increase,
Hydraulic Axial Constant Pressure Variable Pump PCY Series
hydraulic transient increase, constant pressure valve oil discharge port to open large inlet off small, more variable piston chamber pressure under the lower chamber, variable piston moving up, the pump flow decreases, until the pressure constant pressure down to it is set, then the balance of the variable piston position in the new work. Conversely, if hydraulic damping (load) decreases, hydraulic transient decline in constant pressure inlet valve to open large oil discharge port off small, variable piston hydraulic chamber cavity under relatively higher variable piston moves down, the pump increasing the flow until the pressure to which it is set up constant pressure.
We offer the PCY hydraulic axial constant pressure variable pump serious of : 10PCY14-1B, 25PCY14-1B,40PCY14-1B,63PCY14-1B,80PCY14-1B,160PCY14-1B,250PCY14-1B, 400PCY14-1B
