Portable Screw Compressor

1. The original imported airend is used to ensure high effciency and stability, and smoother cutting.

2. Multiple protection devices, multiple shock and noise reduction configurations, low noise.

3. High-effciency refrigerant dryer and 5-level high-effciency special precision filter, high filtration accuracy, pressure dew point as low as 2~5°C, gas oil content as low as 0.001PPM, particulate matter filtration accuracy up to 0.01um, ensuring pure compression air.

4. Constant temperature control. The start and stop of the cooling fan can be set according to the season for the

better control on oil temperature to avoid emulsification.

5. The 500L large air storage tank has buffered air and stable air supply.

6. Centralized drainage aer post-treatment is helpful to keep the customer's site clean.

Due to the closed-loop design of the system, synthetic products are particularly suitable for portable screw compressor. The lubricating oil and compressed gas enter the separator. The separated oil passes through an oil cooler and flows back into the compressor. The degradation of lubricating oil in this process can lead to compressor problems such as bearing failure, insufficient sealing or corrosion.

In many applications, the use of synthetic compressor lubricants can result in effective hydrocarbon compression and gas production. Centrifugal compressors are mainly composed of a rotor and a stator. The rotor includes an impeller and a shaft. There are blades on the impeller, in addition to the balance disc and part of the shaft seal. The main body of the stator is the casing (cylinder), and the stator is also arranged with a diffuser, a curve, a return device, an air pipe, an exhaust pipe, and a partial shaft seal. The working principle of the centrifugal compressor is that when the impeller rotates at a high speed, the gas rotates with it. Under the action of centrifugal force, the gas is thrown into the diffuser behind, and a vacuum zone is formed at the impeller. At this time, the outside fresh gas enter the impeller. The impeller continuously rotates, and the gas is continuously sucked in and thrown out, thereby maintaining a continuous flow of gas.

Compared with reciprocating compressors, centrifugal compressors have the following advantages: 1. Compact structure, small size, light weight; 2. Continuous and uniform exhaust, no need for interstage intermediate tanks and other devices; 3. Small vibration and easy There are few damaged parts and no large and heavy foundation is required; 4. Except for bearings, the internal parts of the machine do not need lubrication, save oil, and do not pollute the compressed gas; 5. High speed; 6. Small maintenance and easy adjustment. The centrifugal compressor transfers the energy of the prime mover to the gas through the high-speed rotating impeller, so that the gas pressure and speed are increased, and the gas converts the speed energy into pressure energy in the fixed element of the portable screw compressor. Mainly used to compress and transport gas.

The working principle of the centrifugal compressor is that after the gas enters the impeller of the entrifugal compressor, under the action of the impeller blades, it rotates with the impeller at high speed while flowing to the outlet of the impeller under the action of the rotating centrifugal force, and is diffused by the impeller. After the gas enters the diffuser, the kinetic energy is further converted into pressure energy, and the gas flows into the next stage impeller through the bend and reflux device for further compression, so that the gas pressure can reach the process requirement Requirements.

Portable screw compressor have the advantages of simple structure, simple operation, fewer wearing parts, convenient replacement of accessories, low noise and safe and reliable operation, so they are more and more widely used in enterprises. However, if the maintenance measures are not correct or the operation is improper, it will cause more equipment failures and reduced service life, which will affect the normal operation of the unit. To keep the compressor unit working normally and reliably, with a long working life, it is necessary to formulate a detailed maintenance plan, perform scheduled operations, regular maintenance, and regular inspection and maintenance to keep the compressor clean, oil-free, and dirt-free. Only a comprehensive grasp of common sense of maintenance and familiarity with troubleshooting methods can ensure the smooth operation of the compressor.
