Cause one: The power supply is incorrectly connected or disconnected;Cause two: The AC contactor coil is burned;Cause three: The overload relay contacts are burnt out;Cause four: High and low voltage protection switch contacts are burned;Cause five: The fuse or no-fuse switch has tripped;Cause six: Read More

Failure situation: After the device trips, the failure indicator will indicate that the device cannot be turned on.Cause two: internal leakage of refrigerantInternal leak can be detected by compressed air or segmented detection1.Compressed air detection methodOpen the bypass valve of the air line an Read More

Failure situation: After the device trips, the failure indicator will indicate that the device cannot be turned on.Cause one: The external leakage of the refrigerant in the equipment refrigeration system.External leakage can be checked visually or with soapy water (mainly check the following points) Read More

Compressed air is an important power widely used in various fields of industry. Compressed air comes from the atmosphere. The atmosphere contains a large amount of water vapor and dust. Together with the oil pollution generated when the air compressor is running, it quickly wears pneumatic equipment Read More

Daily maintenance of the air dryerCheck whether the condenser is clean before starting to avoid poor heat dissipation;Check whether the safety device is reliable before starting;Check whether the working pressure and working current are normal after the equipment runs for 10-20min;After running in c Read More

Clean the back condenser of the equipment more than once a week with dry compressed air or copper;Check the automatic drain valve for any blockages every month, and clean it if necessary;Every three months, check whether the fan blades of the cooling fan have any bad vibration.Check and tighten all Read More

Fault situation: The fault indicator lights up after the device trips. After the pressure drops, after pressing the reset button on the high and low pressure switch, the fault indicator goes out, and the device starts to run as usual.Cause one: The ambient temperature of the air dryer place is too h Read More

Method 1: Is there oil in the compressed air (can be checked on site)Method 2: whether the sprayed raw materials are clean (can be tested on site)Method 3: Is there any problem with the spray gun (can be operated on site)Method 4: Is there any problem with the cleaning agent of the spray gun (can be Read More

Failure situation: Moisture at the gas siteCause one: The automatic drain valve does not drain.Cause two: The evaporation temperature of the air dryer is too high.Cause three: The evaporation temperature of the air dryer is too low.Cause four: The horsepower of the air compressor does not match the Read More

1.Purification flow is too low: re-set according to purification pressure2.Low inlet pressure: recalculate and set the purge pressure3.Excessive moisture content: check aftercooler and pre-filter drain valve4.Inlet temperature is too high: Check the compressor outlet5.The inlet air volume is too lar Read More
