What are the common faults of Chigo screw air compressors?

　　Performance characteristics of screw air compressor:
　　
　　1。 Stable performance. The structure of screw air compressor is relatively simple, the number of parts required is very small, and there are almost no parts that are easy to wear. Therefore, the screw air compressor can operate reliably for a long time, and the performance is very stable. The service life is generally long, and the need for major repairs may occur after 40,000 to 80,000 hours.
　　
　　2。 Simple operation and maintenance. Due to the simple structure, the operation and maintenance of the screw air compressor is also very convenient.
　　
　　3。 The screw air compressor is relatively small in size, not large in weight, and has little actual footprint, and has better dynamic balance performance.
　　
　　4。 Relatively adaptable. Forced gas transmission is one of the characteristics of screw air compressor, its volumetric flow is not affected by exhaust pressure, strong adaptability, can maintain long-term operating efficiency in many harsh environments. Therefore, there are many working fluids suitable for screw air compressors.
　　
　　5。 Multi-phase mixing. The screw air compressor has strong chemical resistance, can withstand many different liquid impacts, and can transport liquid gases, dust-containing gases, easy-to-polymerize gases, etc.
　　
　　Several common faults of screw air compressors:
　　
　　1. The air compressor cannot be started for no reason
　　
　　Check if there is a control voltage. If not, you need to check whether the fuse, etc. is intact; If there is a control voltage, check whether the control relay and time relay are operating normally.
　　
　　2. The air compressor air supply is abnormal Check whether the control cylinder has action and action, and check whether the butterfly valve has mechanical failure; Trouble-free, check whether the loaded electromagnetic ISV coil has suction; After eliminating the mechanical fault of the ISV solenoid valve and the coil fault, check the sub-circuit where the solenoid valve ISV is located one by one.
　　
　　3. The exhaust pressure of the air compressor is too low
　　
　　Check the pressure before and after separation, check whether there is leakage in the gas line, whether the butterfly valve is all open, whether the intake regulator is working normally, whether the solenoid valve 3SV and 8SV are leaking, whether the pressure switch IPS needs to be readjusted, etc.
　　
　　4. Automatic shutdown
during air compressor operation 　　
　　First, check whether the machine is normal and automatically shut down; Then check whether the automatic switch and thermal relay operate, whether it causes the cooling fan motor to stop, or the exhaust temperature is too high, or the pressure is too high, and whether the motor voltage is normal.
　　
　　5. The exhaust temperature of the air compressor is too high< br /> 　　
　　First, check whether the ambient temperature, compressor lubricating oil, oil level, oil quality, refrigeration fan, etc. are normal; Then check whether the oil cooler and aftercooler are clean, whether the temperature control valve element, the oil shut-off solenoid valve voltage and the valve body part are normal, if the diaphragm is damaged, the temperature control valve core does not operate, etc., it needs to be replaced; Finally, check to see if the oil filter is dirty or needs to be replaced. The exhaust temperature is normally 80~95 °C.
　　
　　6. The air compressor does not start smoothly< br /> 　　
　　It is recommended to check whether the switch trips, whether the voltage is normal, whether the degree of closure of the intake butterfly valve is normal and whether the contactor and motor are normal in Y-△ start-up.
　　
　　7. The inlet fuel injection of the air compressor causes the shutdown
　　
　　First check whether the oil shut-off solenoid valve 5SV has voltage and whether the mechanical part is normal; If normal, check the check valve for reassembly or replacement.
　　
　　8. The air compressor consumes a large amount of fuel
　　
　　Check whether the oil content of condensate discharged from the trap is too large, whether the compressor oil level is high, whether the minimum pressure valve opening pressure is normal, whether the return pipe is blocked, whether the oil separation core is blocked, etc. The above problems will affect fuel consumption, if there is a problem, it should be dealt with in time.
