(6) Other aspects of the fault. Common are the mating surfaces of the crankshaft pulley and the relative slip Pine pressure valve stuck in loose causing air compressor pressure state. Intake, air stalls à seat loose or broken valve spring and so on. These failures will cause displacement too little or inadequate exhaust pressure, but relatively easy to rule out. Just identify the reasons, according to specification requirements process can use. Such as found in the seat, valve wear, defects such as scratches or grooves, oil-free screw Germany, milling methods can be used to repair. In the grinding plate with a fine abrasive paste polishing, oil-free screw Berg, the application of hand pressed against the valve seat or valve and press "∞" shape movement, oil-free screw and avoid grinding deflection. If you can not eliminate the defect, it should be replaced. After the restoration of the seat, the valve, before application when using kerosene tightness test j allowing a slight leakage test Ying like, oil-free screw air compressor machinery Xingchang, German oil-free screw air compressor from Qingdao Xingchang Machinery Limited. Oil-free screw air compressor Xingchang machinery, oil-free screw Germany Pneumatic Machinery Co., Ltd. Qingdao Xingchang (www.xckyj.com) this year introduced a new upgrade, the above picture is for reference only, please call or pictures on this page contact telephone number, to obtain the latest information, contact: Cui Junbo.
