High and low temperature test chamber compressor maintenance knowledge introduction
High and low temperature test chambers can provide high temperature and low temperature environments. Parts and materials of related products such as automobile motorcycles, aerospace, ship weapons, electrical and electronic products, etc., need to be routinely tested in high and low temperature environments to specifically test their performance. The stability of the indicator. Today, Shanghai Linpin Instrument focuses on the maintenance and repair of high and low temperature test chamber compressors.
Routine maintenance of high and low temperature test chambers:
1. Check the surface of the oil cooler and clean it if necessary;
2. Cleaning the water separator;
3. Check all wire connections and reinforce them;
4. Check the contact of the AC contactor;
5. Clean the surface of the motor suction port and the surface of the casing.
Daily maintenance of high and low temperature test chambers:
1. Check the air filter and coolant level;
2. Check the hose and all the fittings for leaks;
3. Check the intake air temperature and exhaust temperature of each level, and clean the oil cooler if necessary;
4. Check the bearing oil pressure and oil temperature, and clean the oil cooler if necessary;
5. Check the condensate discharge. If the displacement is too small or there is no condensate discharge, the water separator must be shut down.
special reminder:
The electrical wiring should be correct; during the use of the equipment, the voltage is unstable, causing the current to be too large or too small. Long-term operation under this condition will cause damage to the compressor; if the system is not clean, the compressor will be damaged; it is not recommended to add other compressors. For oils, the refrigeration oil should be added with the compressor model; the machine should be turned on and off frequently during the test, and the compressor should be started again after the machine stops, and the interval should be more than 10 minutes.
Under normal circumstances, there is less chance of sudden damage to the high and low temperature test chambers. Most of the faults are caused by the gradual development of slight wear of the parts; if the fault signs are found and removed in the early stage of wear or deterioration of the parts, It is possible to prevent the development of deterioration and the occurrence of malfunctions, and equipment inspection is an extremely effective means for early detection of signs and early detection of hidden dangers.
