Causes of hydraulic system suffocation may include:
1. Unreasonable valve setting in hydraulic system leads to excessive pressure.
2. The high oil temperature in the hydraulic system reduces the viscosity and fluidity of hydraulic oil, thus affecting the normal work of the hydraulic system.
3. The hydraulic oil used in the hydraulic system is of poor quality, which is easy to produce bubbles and impurities, affecting the normal work of the hydraulic system.
In view of the problem that the hydraulic system will suffocate when the pressure rises, what needs to be done is:
1. Re-adjust the valve settings in the system to ensure that the pressure in the hydraulic system is not too high.
2. Pay attention to the oil temperature in the hydraulic system and take corresponding measures, such as adding radiator and replacing hydraulic oil, to reduce the oil temperature.
3. Replace the hydraulic oil regularly, strengthen the maintenance of the hydraulic system, and ensure the normal work of the hydraulic system.
If the above methods can't solve the problem, it is recommended to seek the help of professional hydraulic equipment maintenance service.
