1. The United States joined the new technology, with over 30 years history of R & D into production, the output value of 43 million, the annual output of 800 units. .2 Northwest ranking first in the industry. Owned Cottle 'licensing screw air compressor manufacturing technology has reached world-class level, 3 national key projects have been selected in the Three Gorges, the Qinghai-Tibet railway is the national professional production, One base compressor developed high-performance configuration, a European import host large rotors, low speed design. 2.SKF precision bearings, seal air compressor brands offer high quality, reliable, energy saving, long life 3. famous brand four motor, F class insulation rating, IP54 degree of protection, the use of reliable, high-quality Baosteel cold rolled plate cover with baking temperature 250 ℃, bring ultra-long anti-corrosion, durable and efficient energy-saving and low operating costs, 1 screw compressor brand highly intelligent, automatic adjustment for optimal body running Cottle empty . press brand, two energy efficient at the same time, to extend the life of the body, the maintenance period of more than 4000 hours an air filter clogged air filter needs to be replaced; 2, the vent valve can not be closed, need maintenance vent valve; 3, air demand greater than the nominal displacement compressor; 4, the intake valve closed in advance, check and unloading valve solenoid valve, pressure regulator is working properly, replace the service pack if necessary; check the computer board / pressure switch setting is appropriate. An intermediate pressure compressor cold and dry process can not start Failure Analysis: Step 1: Check the information on the display panel of the dryer, the indicator whether the abnormal phenomenon. When the high pressure anomaly lights could be: less cooling water, high temperature, condenser does not work damaged or blocked, air flow over the source. When the low-voltage lights might be an exception: the refrigerant filter is not working properly, damaged or blocked. Step Two: Check remote start relay normally open contact. Step 3: Check the dryer voltage. Step four: start point on the use of the dryer panel boot device.
