During using the constant temperature and humidity testing chamber，there may be some malfunction， compressor as an important part of this machine, we need to maintain it in order to make better use of the entire machine.
1 Be careful examination of the cylinder and the moving parts of the action at all levels of sound according to "listen" to distinguish whether it is working properly, if we find an abnormal sound immediately stop checking;
2 Note gauge levels within the range indicated value gauge and oil pressure gauge on the tank and cooler whether prescribed;
3 Check the cooling water temperature, flow is normal;
4 Check the oil supply, the oil lubrication system case sports organizations (some compressor crosshead guide side of the fuselage is equipped with plexiglass tailgate, you can directly see the availability of crosshead movement and lubricants); cylinder , fillers can be used as a way to put cutting oil check, you can check the oiler oiling situation to the cylinder;
5 observed body surface and the oil sump oiling the oil is below the tick should promptly as low add enough (oil feet shall stop and check);
6 hand touched the cross rail inspection body crankcase cover, etc. at the suction and discharge cutting temperature is normal;
7 Note that the motor temperature, bearing temperature and voltmeter, ammeter indicates the situation is normal, the current does not exceed the rated motor current, if exceeded, looking for cause or stop to check;
8 Always check whether the debris inside the motor or conductive objects, whether there is damage to the coil, stator, the rotor has friction, otherwise the motor will start the motor burned out;
9 if it is not immediately pass into the water without water after a water-cooled compressor if you want to avoid cracks in the cylinder occurs Enthusiasm winter parking to let go of the cylinder cooling water to avoid cracking, etc.;
10 to check whether the compressor vibration, ground screw loose and fall off phenomenon;
11 Check the pressure regulator or load regulator, safety valve, etc. are sensitive;
12 Note compressor and an equipment and environmental hygiene;
13 tank, cooler, water separator must often release water;
14 used lubricating confidential precipitate filtered. Winter and summer to distinguish between the use of compressor oil.
