Twin screw air compressor with single screw air compressor difference

Twin screw air compressor with single screw air compressor difference

(1) manufacturing cost:

Single screw compressor screw and wheel bearing can adopt ordinary bearing, low manufacture cost; twin-screw type air compressor screw rotor for two with the comparison, the selection requirements of bearings with higher accuracy, higher manufacturing cost.

(2) efficiency:

With the movement time increased, the single screw compressor wheel wear will cause the volume reduction and efficiency.

(3) operation and maintenance:

Single screw air compressor and screw air compressor for daily operation and maintenance is basically the same.

(4) force balance:

Single screw compressor screw under radial and axial force can automatically balance, star wheel under air force requirements, star-wheel tooth has enough strength and rigidity; double screw type air compressor screw rotor bear large radial and axial force, requirements of screw has enough strength and rigidity.

(5) the processing equipment:

Single screw air compressor without mature dedicated processing equipment, resulting in product performance is not very stable. Twin screw air compressor has been a mature screw milling machine and grinder, can ensure product performance and stability.

(6) noise and vibration:

Single screw compressor and screw type air compressor vibration and noise of basically the same.

(7) reliability:

Single screw compressor wheel is wearing parts, except for the star wheel material have higher requirements, also need regular replacement. Twin screw air compressor without wearing parts, trouble-free operation time of up to 40000-8 million H ( intermediate required regular overhaul).

(8) the processing equipment:

Single screw air compressor without mature dedicated processing equipment, resulting in product performance is not very stable. Twin screw air compressor has been a mature screw milling machine and grinder, can ensure product performance and stability.

(9) applicability:

Single screw air compressor for high exhaust pressure. Twin screw air compressor due to the rigidity of rotor and bearing load and other aspects, the twin-screw air compressor can only apply in low pressure exhaust pressure, range, generally not more than4.5MPa.

Summary:

Single screw and twin screw from the structure, double screw manufacturing process than single screw complex, in the new machine state, single screw compressor and screw compressor efficiency basically the same. But at present domestic single screw twin-screw manufacturing technology not mature, the main problem is to solve the transmission and sealing, that is to say the life and the maintenance of single screw to lack some.
