Solutions to general failures of power units

As a hydraulic power system, the power unit generally has some minor faults. In fact, these minor faults are normal, so how to solve these faults? The power unit manufacturers summarize a few points below, you can refer to them.

1. The motor does not rotate, check the correctness of the connection line.

2. When the motor starts, the oil cylinder does not rise or rises unsteadily

(1) The oil level in the oil cylinder is too low, add oil to the specified oil level;

(2) If the viscosity of the oil is too large or too small, use the recommended hydraulic oil;

(3) The suction filter is blocked, clean or replace the filter;

(4) The oil suction pipe is not sealed or leaks. Check for leaks or leaks and repair or change the suction pipe;

(5) The solenoid valve or manual valve is not closed, clean or replace the solenoid valve or manual valve;

Vibration sources (such as hydraulic pumps, hydraulic motors, motors, etc.) often occur in hydraulic systems to cause resonance in the bottom plate, pipes and other parts; or the resonance of pumps, valves and other components may cause greater noise. For this phenomenon, the natural vibration frequency of the pipeline can be changed by changing the length of the pipeline, and the installation position of some valves can be changed to eliminate it.

The hydraulic oil has deteriorated or has impurities. After the hydraulic oil has been used for a long time, there may be impurities or deterioration in the hydraulic oil. Take a sample and check it to see if it contains fluid particles, discoloration, or odor. Change the hydraulic oil when necessary. The hydraulic pump is also a key factor affecting the flow of hydraulic oil. After long-term use, the hydraulic pump will easily cause wear. When the speed of the hydraulic lift platform slows down, check whether the oil supply flow of the hydraulic pump remains unchanged. If it is worn out, contact the manufacturer in time to avoid the warranty period.

The above is the solution to the general failure of the power unit. The power unit is optimized for various application conditions. For example, it can be used for truck operation in harsh environments, or used for heavy-duty handling conditions for a long time, and other requirements that require high performance and high quality. The occasion of the product. As a result, an extremely diverse platform has been produced. The use of standard components can cope with most of the application conditions required by the market. The inventory of the customer's hydraulic components is minimized, and the workload of non-standard designs is also greatly reduced.
