Single screw air compressor has the advantages of reasonable structure, with the ideal of the force balance and energy efficient and unique. The double screw air compressor machine has the advantages of simple structure, few wearing parts, soscrew host reliable operation, long service life and easy operation and easy maintenance. Dynamic balance is excellent.

The following records and air compressor water heater master detail for you a bizarre world of single screw and twin screw of future generations:

In the new machine state, single screw air compressor and double screw compressorefficiency, noise and vibration has basically the same. But with the increase of the running time of single screw air compressor, wheel wear will likely result in lowervolume reduction and efficiency.

In the force balance, single screw air compressor screw bear radial and axial gas force can be automatically balanced, under air force requirements of star wheel,sprocket wheel tooth has sufficient strength and rigidity. The double screw air compressor screw rotor under radial and axial gas force, requirements of screw has sufficient strength and rigidity.

Reliability: the star wheel single screw air compressor is wearing parts, except for the star wheel material has high requirements, star also need regular replacement.Double screw air compressor without wearing parts, trouble free operation time can be up to 5-10 years.

Product performance and stability: single screw air compressor without special processing equipment for mature, resulting in the performance of products is not very stable. Double screw air compressor is ripe for screw milling and grinding machine, to ensure stable product performance.

Manufacturing cost: single screw air compressor screw and a star wheel bearings canuse ordinary bearing, low manufacturing cost. Double screw compressor due to relatively large two screw rotor load bearing requirements, use high precision, so the manufacturing cost is relatively high.

Universal applicability: occasions single screw air compressor is suitable for high exhaust pressure (such as high pressure air compressor, refrigeration and aircompressor and gas air compressor etc.. ) double screw air compressor due to rotor rigidity and bearing load and other constraints, the general is only suitable for low pressure range,, (such as power air compressor, refrigeration compressor and low-pressure natural gas compressor.) And the exhaust pressure is generally not more than 4.5MPa.

Reminder.

Chronicles and the electromechanical device limited company to recommend air compressor, water heater, air compressor heat recovery equipment, as long as youhave the air compressor factory, can 0 operation cost of producing hot water andheating. See details > >
