Single screw compressor structure features

The superior performance of Shanghai Shenlong Single Screw Compressor has unique advantages in addition to its simple structure, small size and no air valve components.

1, the structure is reasonable, with ideal balance of force.

Since the star wheel is arranged symmetrically on both sides of the screw, the radial gases acting on the screw cancel each other out, and the axial load on the gas in the screw groove also cancels out each other. In addition, there are bleed air passages between the two ends of the screw, so the effect is The gas forces on both sides of the screw also cancel themselves. Therefore, the screw does not bear any radial or axial gas force, and the gas force on the star wheel teeth is very small, which is only about 1/30 of that of the piston compressor or twin screw compressor.

2, energy efficient.

When the single-screw compressor is working, each revolution of the worm, each worm gear operates twice, so that the worm groove space can be fully utilized. Compared with other rotary compressors, the structure size is small, and the worm groove depth of the worm is also As the pressure in the compression chamber increases, it becomes shallower, and it is zero at the end of the exhaust. Theoretically, there is no clearance volume and the volumetric efficiency is high. The single-screw compressor has a complete control system, with servo-type stepless automatic adjustment of gas volume, automatic unloading and load conversion, automatic shutdown and automatic start and other functions to meet the needs of different users of gas consumption, significant energy saving, no-load operation, Its power consumption can be reduced by 60%.

3, low vibration, low noise.

Due to the rational design of the compressor main engine, high speed and light load, the design of the meshing sub line type is advanced. The worm generates 12 compression cycles per revolution, exhausts 35,280 times per minute, and there is almost no pulsation in the exhaust. Therefore, the vibration is minimal, and noise and noise reduction devices are used. Therefore, the noise is low, and a quiet working environment can be maintained. Due to the above reasons, when the compressor is operating at full capacity, a coin will not stand on the body.

4, long life.

The single-screw compressor has a novel main structure. The worm rod has no axial force and radial force load, and is in a fully balanced state. The bearing life is as long as 100,000 hours, which overcomes the shortcomings of the twin-screw air compressor bearing's vulnerability and its durability exceeds the current type of air compressor. machine.

5, high reliability.

Excellent science and technology in design, excellent production technology, and high-precision special equipment ensure the quality of products. Only routine replacement of air filter cores, oil filter cartridges, oil and gas separation filter cartridges, and compressor oil are required in daily operations. The maintenance cost is reduced to a low level, the overall layout is compact and reasonable, the volume is small and exquisite, the cover is dismantled, the replacement of parts is very quick and convenient, the installation is quick, and the installation base can be used once it is in place.

6, safe operation device.

The operation control surface is provided with a monitoring device to display various relevant parameters and working conditions, and the operation status and fault display are clear at a glance. Overpressure protection, over-temperature protection, motor overload protection, water cut protection, phase-failure and phase-fill protection are carefully set. Filter plugging light alarm. In the emergency stop, over-temperature protection, overload protection and so on are all interlocked protection functions. In addition PLC control, man-machine interface, multi-machine joint control, fortune and online monitoring, a variety of control modes available to the user to choose.
