Daikin screw compressor repair a single screw refrigeration compressor main brands are: (McQuay) McQuay, Mitsubishi, Daikin. Second, single, twin-screw compressor differences: a force balance (superior twin screw single screw single screw compressor: Screw gas bear radial and axial force can be self-balancing, star bear tooth gas force, requiring the star wheel The teeth have sufficient strength and rigidity can force it suffered as a zero, so the choice of bearing just plain bearings can be twin-screw compressor: screw rotor withstand greater radial and axial gas force, Requirements screw has sufficient strength and rigidity. needs a steady flow of fuel system and refrigeration oil. and uses two high-precision bearings work. maintenance of single screw compressor and twin-screw compressor daily work and maintain the same 3 Applicability aspects of a single screw compressor: suitable for high discharge pressure of the occasion, such as high-pressure air compressors, refrigeration compressors and gas compressors, twin-screw compressor: Due to the limitations of the rotor load bearing stiffness and other aspects of the twin-screw The compressor will only apply to the low pressure range, such as power air compressors, refrigeration compressors and low-pressure natural gas compressors, exhaust pressure is generally not more than 4.5MPa) 4 single screw compressor manufacturing costs: the screw and star Wheel bearings can use an ordinary bearing, but the star wheel and star wheel with wear-resistant graphite sheet, difficult process, higher manufacturing costs. Twin-screw compressor: As the two screw rotor load is relatively large, requiring selection of high precision bearings, bearing high costs. 5, single screw compressor reliability: star wheel single screw compressor is a consumable part, but their injection cooling is relatively small, very little oil will be able to meet their own requirements, bearing life is a twin-screw 3- 5 times. Twin-screw compressor: twin-screw compressor is no wearing parts, but demanding fuel system, fuel poor leads to axle. 6 efficiency in the new machine state, single screw compressor and twin-screw compressor efficiency is basically the same. As the running time increases, single screw compressor will cause star wheel wear volume reduction and reduced efficiency. 7 noise and vibration than single screw compressor forces suffered zero, so noise is less than and twin-screw compressor. 8 processing equipment single screw compressor: no mature processing equipment, which led to the performance of the product is not very stable. Twin-screw compressor: screw has mature special milling and grinding machines to ensure product performance and stability. I'm more of a safety equipment company to give you more of a worry.
