Fault and Replacement Suggestions: If the thermostat valve gets stuck (unable to open or close), it will cause: Low oil temperature (always bypassing the cooler): The high viscosity of the oil increases the load on the engine and energy consumption; High oil temperature (always on the cooling): Especially in low-temperature environments, the oil heats up slowly, and the lubrication effect declines. Suggestions: When you notice abnormal oil temperature (deviating from the normal range by more than ±10℃), check the status of the thermostat valve; When there is a fault, replace the original factory thermostat valve to avoid using an alternative part that leads to insufficient temperature control accuracy; When replacing, clean the pipe interface to ensure the correct installation direction of the valve (according to the arrow indication on the valve body), to prevent installation in the wrong position from affecting the function.

Troubleshooting and Replacement Suggestions: Common Issues and Solutions: Stalling or Leakage: Causes unstable pressure and increased energy consumption. It is recommended to disassemble and clean or replace directly (it is suggested to replace the entire set to avoid matching issues between new and old components). Reduced Adjustment Precision: Mostly due to wear of sensors or valve cores. Replacement of the original kit is required and recalibration is necessary. Installation Tips: After replacement, parameter matching through the controller (such as setting pressure upper and lower limits) is necessary to ensure normal system linkage.

Replacement and Maintenance Recommendations: Replacement Cycle: Generally, replace once every 3,000 - 4,000 hours or annually (whichever comes first). In harsh environments, the cycle should be shortened; Replacement Indicators: If the oil content in the compressed air exceeds the standard (oil stains appear at the air inlet), or if the pressure difference between the separator inlet and outlet is too high (more than 0.8 - 1.0 bar), replace immediately; Installation Notes: During replacement, clean the interface, check the integrity of the sealing ring, and tighten according to the specified torque; after replacement, discharge the air inside the tank to ensure the system operates normally.

Maintenance and Replacement Specifications: Regular Calibration: According to industry standards, safety valves need to be calibrated by professional institutions on a regular basis (typically once a year) to ensure accurate pressure setting and reliable operation; Replacement Timing: If there is valve body leakage, malfunction, or if the calibration is不合格， the original factory safety valve must be replaced immediately. Do not attempt to adjust or repair it yourself； Installation Considerations： During replacement， ensure that the system is depressurized， the installation direction is correct (usually the valve body has a medium flow direction arrow)， the interface is well sealed， and do not install it in reverse or block the exhaust port.

Fault and Replacement Suggestions: If the check valve experiences leakage, sticking, or fails to close completely, it may result in decreased system pressure, increased energy consumption, or reverse rotation of the main unit. Suggestion: Regularly check the sealing performance of the valves (this can be determined through pressure retention tests); When a fault is detected, replace the entire original equipment set (instead of just replacing individual components) to ensure the compatibility of all components; When replacing, clean the pipe interface, tighten according to the specified torque, and avoid leakage caused by improper installation.

Replacement and Maintenance Precautions: If cracks, deformations, damage to the sealing parts, or worn-out connection threads occur on the shell, it must be replaced immediately. Otherwise, unfiltered air will directly enter the main unit, causing wear and tear on components such as rotors and bearings. During daily maintenance, it is necessary to check whether the seal between the shell and the filter element is intact, and clean the dust and impurities inside the shell (especially when replacing the filter element). When installing a new shell, ensure that the sealing ring is installed properly, and tighten the connecting bolts according to the specified torque to avoid air leakage or damage to the shell due to vibration.
