<br> First, failures and trouble <BR> <BR> compressor may be faulty and repair methods in Table II. .<BR> <BR> <BR> Second, adjustment and maintenance <BR> 1. .<BR> <BR> Inhaled air filter dust in the air in the filter was blocked in order to avoid premature wear and the compressor is oil separator is blocked, usually in operation after 1000 hours or one year, .To replace the air filter in dusty areas, the replacement intervals should be shortened. .Filter maintenance must be shut down, in order to reduce the proposed parking time has been put on a new or cleaned filter backup. .Clean filter as follows: a front surface of a flat surface at both ends of the filter tap turns to remove most of the heavy and dry Fui Sha. .b is less than 0.28MPa with dry air in the opposite direction along the inhaled air blowing nozzle and the folded paper at least 25 mm apart, and blowing up and down along its direction. .c If there is oil filter should be replaced with new filter. .d put a light inside the filter to check, if found thinning, a pinhole or breakage of the Department should be abandoned. .<BR> <BR> 2. .<BR> <BR> A. cooler units for air cooling, the plate-fin cooler pay special attention to the external surface of clean, otherwise it will reduce the cooling effect and should therefore be based on working conditions, regular cleaning. .<BR> <BR> Cleaning method: Cooler with fiber brush to remove dust. .Do not use wire brush or metal products made dust. .Then the reverse air purge and cooling air cooler. .If it is necessary for internal cleaning with cleaning agent, please contact Wuxi Compressor Co., Ltd.. .<BR> <BR> B. For the water cooling unit, the tube shell and tube cooler, the outer surface of the special attention to clean, otherwise it will reduce the cooling effect, it should be based on working conditions, regular cleaning. .Before cleaning, please contact Wuxi Compressor Co., Ltd.. .<BR> <BR> 3. .<BR> <BR> Oil separator oil and gas separator according to the standard pressure vessel manufacturing and inspection, shall be arbitrarily modified. .<BR> <BR> 4. .<BR> <BR> Safety valve installed on the gas valve on the separator checked at least once a year, adjust the valve to be undertaken by hand, at least every three months Larsson what leverage one, the valve opening and closing time, .to ensure that the safety valve is working. .<BR> <BR> Test as follows: (1) Close supply valve (2) Start Unit (3) <BR> <BR> observation side of the pressure side and slowly rotate clockwise pressure regulator adjusting screw ., when the pressure to reach the required value, the valve has not yet reached the specified value before the open or open, it must be adjusted. .Safety valve adjustment must be adjusted by a professional testing organization. .You may not adjust, or peril. .<BR> <BR> 5. .Motor overload relay <BR> <BR> relay under normal circumstances, contact should be closed, when the current exceeds the rated value, open, cut off electrical power. .<BR> <BR> 6. .The adjustment of the pressure off <BR> <BR> stepless adjustment and the pressure of the two adjustment methods must be staggered, such as the stagger is too small, their actions overlap pressure, then adjust the way the two interfere with each other, then to be .stagger value increases the pressure. .Which way to adjust the pressure setting is reached first, the unit for the implementation of the regulation. .<BR> <BR> A pressure regulator off adjustments: Loosen the pressure regulator cover, rotating the screw hole, adjust the load pressure (pressure increases clockwise, counterclockwise rotation, the pressure reduced); load .After the pressure setting, then adjust the knob below the differential pressure, differential pressure plus the pressure is the maximum load pressure (unloading pressure). .<BR> <BR> B stepless pressure adjustment: Loosen the regulator regulator and the mother of rotating the handle clockwise the pressure increases, and vice versa reduced. .<BR> <BR>.
