Humble Screw Compressor Repair 1 http://mehrespand.irIn this part of the video series on repairing screw and piston cylinder compressors, which includes all screw and piston cylinder compressors from Carrier, Bitzer, DVM, Copeland, etc., you can see how to open various components of a Humble Screw Compressor. http://mehrespand.ir/?p=98 In the first part of this series, the method of opening and identifying mechanical components is described, and in the following parts, the method of using tolerances to repair the compressor is described in detail http://mehrespand.ir/?p=87 Because if tolerances are not used for compressor repairs, you will not be able to repair the components accurately. http://mehrespand.ir/?p=90 For advice, you can contact the technical experts of Mehraspand Engineering Group. http://mehrespand.ir/?p=1478 Screw Compressor Startup Limits Minimum Startup Voltage: There should not be a voltage drop of more than 10% of the working voltage during startup. http://mehrespand.ir/?p=191 Maximum discharge pressure: 18kg/cm2G 。 Minimum suction pressure: 6~8 kg/cm2G 。http://mehrespand.ir/?p=60 Air condenser chillers are critical and a load step system should be used in them and the compressor should have coil coolant injection and the discharge temperature should be controlled. If the starting conditions are not high-limit, direct start of the compressor can be used. http://mehrespand.ir/?p=87 Maximum discharge design pressure: 28kg/cm2G Maximum discharge design temperature: 110℃
