Characteristics and operation principle of air compressor for oil free screw air compressor
Screw air compressor is a new type of air compressor. It has been used for less than 20 years. Screw air compressor is very different from traditional air compressor. Screw air compressor has a series of advantages, such as novel structure, small volume, light weight, low noise, long service life, smooth connection of gas transmission, simple operation and low maintenance cost. It is called "no need to repair" by operators "Air compressor" and "new modified air compressor".
The air compressor of screw air compressor is made up of two double function equation profile's dynamic and static vortex disks meshing with each other. In the process of suction, contraction and exhaust operation, the static disk is fixed on the frame, and the dynamic disk is driven by the eccentric shaft and restricted by the anti rotation arrangement. It rolls around the base circle of the static disk with a small radius. The gas is sucked into the periphery of the static disk through the air filter element and rotated with the eccentric shaft. The gas is gradually compressed in a number of crescent shaped compression cavities combined by the dynamic disk occlusion, and then discharged from the axial holes of the static disk base parts.
Screw air compressor air compressor features: first, high reliability. 1) The main machine parts of screw air compressor are few, which is 1 / 8 of the number of piston machines. The substantial reduction of parts is the main factor of product reliability. 2) The rotary radius is small, the linear velocity is only 2m / s, so the wear is small, the mechanical power is high, and the oscillation is small. 3) Scientific control of the whole system to ensure the stability of the product.
2、 The noise is the lowest. 1) Because there is no suction and exhaust valve and disorderly movement arrangement, the knocking sound of valve plate and explosion sound of air flow are eliminated, and the noise is sharply reduced. 2) The suction and exhaust are continuous and stable, more than 6000 times per minute, which makes the airflow pulsation extremely small. 3) A 20HP (15kw) screw air compressor only needs 62dba noise, so that it can be used in any place and place, saving cost and meeting the requirements of environmental protection.
3、 The energy consumption is the lowest. 1) Because of the suction supercharging effect and no spare volume, the volume power of screw air compressor air compressor is as high as 98%. 2) Because several working chambers are gradually compressed, the pressure difference between adjacent working chambers is very small, so there is little natural leakage. A tightening process is divided into several times, and the thermal power rate is high. 3) There is no suction and exhaust valve, so the resistance loss of intake and exhaust is almost zero. No movement arrangement of conflict wear, high mechanical power, this is the screw compressor compressor than other air compressor greatly energy saving primary factor. For example: (1 set of 20hp15kw) screw air compressor works 6000 hours a year, saving electricity up to 18000 yuan.
4、 The maintenance cost is the lowest. The main engine has less parts and less vulnerable parts, which greatly reduces the possibility of parts replacement. It has the advantages of long cycle, convenient operation, less maintenance and low maintenance cost.
5、 Compressed air is 100% oil-free. Oil free air compressor must be needed to produce oil-free compressed air. In pharmaceutical, food, fine electronics and other similar industrial occasions, it is necessary to pay attention to safety. This is why the oil-free air compressor is used in the situation where high purity compressed air is needed. No oil means no risk, no risk of pollution, no risk of product damage or product insecurity, no loss caused by shutdown. All in all, no oil means no risk of damaging the hard won reputation.
