BCY Electro-hydraulic Proportional Variable Axial Piston Pump
BCY14-1B type electro-hydraulic proportional control variable pump has the advantages of flexible control, sensitive action, high repetition accuracy and good stability It can conveniently realize the remote control, automatic control, stepless speed regulation, tracking and feedback synchronization and computer control of the hydraulic system, and is suitable for the requirements of industrial automation
Product Introduction
Product Overview：
In the hydraulic system, the electro-hydraulic proportional variable axial piston pump is widely used because of its flexible control, sensitive action, high repetition accuracy and good stability. At present, the electro-hydraulic proportional variable axial piston pump is used to control its variables by using external oil control source, that is, another set of hydraulic system as the hydraulic source to control the pump variables. The disadvantages of using external control pump to control pump variables are large energy consumption, large volume, high cost and complex process. After using internal control variables, the pump and valve are integrated, with compact structure and significantly reduce the cost.

Working Principle
The main part (see structure section) by the drive shaft drive cylinder rotation, so that the seven plungers evenly distributed on the cylinder revolve around the center line of the drive shaft, through the central spring will slide the slipper in the column slide assembly pressure on the variable head (or swash plate). In this way, the plunger reciprocates with the rotation of the cylinder block to complete the action of oil absorption and oil pressure.
BCY14-1B type electro-hydraulic proportional variable pump control, is the use of the principle of "flow, displacement, force feedback" design, is CY14-1 b type axial piston pump is a new type variable, and by external control hydraulic control variable, and use the current size of proportional electromagnetic valve is input to change the flow of the pump, and pump flow rate is proportional to the input current. The pump has the advantages of flexible control, sensitive action, high repetition accuracy and good stability, and can conveniently realize the remote control, automatic control, stepless speed regulation, tracking and feedback synchronization and computer control of the hydraulic system, which is suitable for the requirements of industrial automation.
