Maintenance of high and low temperature test chambers

High and low temperature test chamber series compressor is one of the important components of the operation of the equipment, Liuqin Technology in the production and sales process for many years, to understand and implement the key part of the high and low temperature test chamber - refrigeration system compressor maintenance of the importance
.
The following technical brief description of the daily high and low temperature test chamber series compressor maintenance instructions
.
Under normal circumstances, the sudden damage of high and low temperature test chamber equipment is rare, and most of the faults are formed due to the gradual development of minor wear of parts; If the signs of failure can be found and removed at the early stage of component wear or deterioration, the development of deterioration and the occurrence of failures can be prevented, and equipment inspection is an extremely effective means
to detect hidden dangers in advance by early detection of signs 。 Daily maintenance contents: 1.
Check the empty filter element and coolant liquid level; 2.
Check whether the hose and all pipe fittings have leaks; 3.
Check the inlet air temperature and exhaust air temperature at all levels, 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 stopped; the monthly maintenance content of the high and low temperature test chamber: 1.
Check the oil cooler surface, if necessary, clean it; 2.
clean the aftercooler; 3.
clean the water separator; 4.
check all wire connections and tighten it; 5.
check the AC contactor contacts ； 6.
Clean the dust on the surface of the motor suction port and the surface of the shell; Quarterly maintenance contents: 1.
main motor filled with grease; 2.
clean the main motor and fan motor; 3.
replace the oil filter core; 4.
clean the oil cooler; 5.
check the temperature sensor and pressure sensor; high and low temperature test chamber annual maintenance content: 1.
replace the coolant; 2.
check the check valve; 3.
check the cooling fan; 4.
check the hydraulic cylinder, if necessary, replace the maintenance components; 5.
check the vent valve, if necessary, replace the maintenance components; 6.
check all metal hoses; special reminders: 1.
The electrical wiring of the high and low temperature test chamber is correct or the power supply meets the requirements; 2.
During the use of the equipment, the voltage is unstable, resulting in excessive or too small current , long-term small work under this condition leads to compressor damage; 3.
The system is not clean and causes compressor damage; 4.
Add other oils to the compressor, and the refrigeration oil supporting the compressor model should be added; 5.
During the test process, the machine is frequently switched on and off, and the compressor is started again after shutdown, and the interval is more than
10 minutes.
