Refrigerated display case refrigeration compressor installation should pay attention to what?

Is the refrigerated cabinets of the most important parts of the compressor, if you usually do not carry out maintenance, better installation, easily lead to later use frequent small failures, then the snow freezer specifically to be summarized some troubleshooting fault knowledge and methods, interested friends can go and find out.
Insufficient cooling output:
Refrigerated display cabinets in use, sometimes you can find refrigerated display cabinets out of the wind changes little, lack of air, if a happens, you can according to the following ways to test for the refrigerated display cabinets:
1, the air intake is closed
。
2, if the pressure gauge shows normal pressure and low pressure gauge shows high pressure, notes, hot gas by-pass valve, evaporator pressure regulator into the spiritvalve failure.
3, if the air temperature is high, and pressure gauge pressure indicator is normal, orhigh, low voltage with a slight increase, the expansion valve filter screen blockage.
4, if the pressure gauge indicating higher than normal pressure, low pressure gaugeindicating lower than normal voltage supplies and receiving dryers and piping icing,the receiver dryer filter block.
5, pressure gauge indicating higher than normal pressure, might have too much moisture in the system. If the bubbles are found in the observation window, mixed withthe air in the system.
Refrigerated display case refrigeration compressor installation notes:
1, the line shall not be used when compressor, exhaust pipes and reservoirs to handling to avoid damage to the compressor looks. (Welding parts leakage).
2, refrigerated display case refrigeration compressor foot anchor fixing nut with thecompressor must be guaranteed a certain amount of clearance, or vibration of the compressor itself easy system vibration caused by passing through anchor bolts to the chassis. The gap between General requirements in 0.5~2mm; note that the installation process not to forcibly break into the retaining nut result in bending deformation of anchor bolts.
3, the Assembly should pay attention to when refrigerated display case refrigerationcompressor and pipes, tubes and tube there should be at least the distance between 15~20mm and touch tube to avoid.
4, and pulled out refrigerated show cabinet refrigeration compressor of rubber plug to welding distribution tube Zhijian of interval time best not over 15 minutes (especially new cold media air conditioning, note shifts and breaks rest Shi don't Park not pulled out rubber plug of compressor), and to note here of process process don't exists may led to has foreign body fell to compressor internal of process (as in compressor above Shang screws,) exists.
Absolute prohibition of any foreign bodies (including any solid, liquid) from the exhaust pipe or suction pipe into the refrigerated display case refrigeration compressorinternal; if there are foreign bodies entering the compressor, do not run the compressor and seal off the production line.
