Simple maintenance method of hydraulic press when there is a problem

Hydraulic press is the use of liquid pressure to transfer power and control a transmission method, widely used in automotive parts processing and various professions of a variety of product styling, mold, handbag, rubber, shaft, stamping, calibration and shoemaking, shaft sleeve parts of the press assembly, stamping, plate parts bending, stamping, sleeve stretching and other processes. Washing machine, motor, automobile motor, air conditioning motor, micro motor, servo motor, wheel manufacturing, shock absorber, motorcycle and machinery.

Hydraulic equipment is composed of hydraulic pump, hydraulic cylinder, hydraulic control valve and hydraulic auxiliary components: hydraulic pump is the conversion equipment that converts mechanical energy into hydraulic energy; Hydraulic cylinder is to convert hydraulic energy into mechanical energy; Control valve is to control the flow of hydraulic oil, flow direction, pressure, the working order of the hydraulic actuator and maintain the hydraulic circuit. Their role is to control and regulate the flow direction, pressure and flow of the hydraulic medium to control the direction of movement of the actuator and the output force or torque. The speed of motion. The action sequence, as well as the restraint and conditioning of the working pressure of the hydraulic system, so as to avoid overload and other functions. The application of oil press in the profession is very widespread and very frequent, which also leads to the possibility of problems with oil press.

When the hydraulic press encounters problems, the following two simple methods can be used to repair the faults of the hydraulic press:

1. The same components of the same type, same structure and same principle of the hydraulic press are exchanged and installed in the same position to prove whether the replaced components work reliably. The advantage of the replacement method is that even if the technical level of the repairman is low, this method can be used to make an accurate diagnosis of the faults of the hydraulic press. However, the use of this method must be based on the same type, the same structure, the same hydraulic principle and the same hydraulic components of the hydraulic press as the condition, so this method has great limitations and certain blindness.

2, by and with the help of simple auxiliary parts, the hydraulic components of the hydraulic press are diagnosed whether they are faulty. Using the ejector rod to reverse the valve components can confirm whether the reversing valve presents problems such as stuck, valve core is not in place. The auxiliary method does not disassemble the parts to confirm whether the hydraulic components are faulty, avoiding too much disassembly workload, reducing the time of fault diagnosis, and facilitating rapid diagnosis, especially about; The diagnosis of larger cylinder seals, etc., has good practicability.
