What should be paid attention to during the use of screw air compressor

During the use of the screw air compressor, some problems need to be paid attention. If the product is used, it will cause the screw air compressor to malfunction or seriously affect the service life of the screw air compressor.

1. Screw air compressor is afraid of dust

Screw air compressor host rotor clearance is smaller than hair, so it is more sensitive to dust. The filtering accuracy of the air filter is generally 15 microns, and then the small dust will directly enter the inside of the head, affecting the host and bearings. Dust, especially metal dust and chemical dust, has a great influence on the host, so the dust problem should be taken into account when choosing the installation position of the screw air compressor. At the same time, we should also strengthen the daily maintenance, clean the air intake filter and air filter every week to prevent the air filter from clogging and causing greater damage.

2. Screw air compressor afraid of chemicals

Screw air compressor host lubrication and heat dissipation is carried out by the lubricating oil, so the normal operation of the equipment on the lubricating oil requirements are relatively high. In addition to selecting qualified lubricating oil, we should also pay attention to the volatile organic solvents, acid and alkaline substances in and around the air compressor room as far as possible. These chemicals will seriously affect the nature of the lubricating oil after entering the lubricating oil, causing the air compressor to have problems such as glue, oil deterioration and loss of lubricity, etc., resulting in serious damage to the air compressor.

3. Screw air compressor afraid of high temperature

Because the lubricating oil has certain requirements for the temperature of use, the temperature is too high, the lubricating oil will produce carbonization phenomenon, so the exhaust temperature of the air compressor is strictly controlled. Under normal circumstances, the shutdown temperature of the air compressor is set at 105 degrees (Atlas air compressor is 120 degrees), and the air compressor will stop autonomously if it exceeds this temperature. The ambient temperature designed for the air compressor is generally 45 degrees, so the temperature of the air pressure room may exceed this upper temperature limit in summer. At this time, we should find ways to ventilate, clean the air intake filter and radiator, install air guide pipes to discharge the hot air generated by the air compressor outdoors, increase convection fans to circulate the air in the air pressure room, and other methods to cool down.

4. Screw air compressor afraid of low temperature

The lubricating oil of screw air compressor has an index called "pour point", which means that the lubricating oil will freeze when reaching this upper temperature. Therefore, in areas with low temperature in the north, the air compressor should be protected after the air compressor is shut down or the oil and gas barrel of the air compressor should be equipped with heating wire and preheated before the air compressor starts again. In the central region where the temperature is not particularly low, protection should also be paid attention to in winter: vent the moisture in the air storage tank and filter after shutdown, and perform jog operation when the air compressor is shut down and restarted. Generally, it can be directly started after 2-3 times of jog.

5. Screw air compressor afraid of wet rain

Screw air compressor internal electronic control system, motor and frequency converter and other electrical components, these electrical components in the humid environment prone to breakdown may, this will cause the circuit short circuit or electrical burning, serious will fire fire. Therefore, it is necessary to keep the air compressor room relatively dry and avoid adjacent to water vapor. In addition, the air compressor room also needs to do a good job of rainproof. At present, the frequency converter used by most frequency conversion air compressors is installed under the radiator. If the air compressor room leaks rain, rainwater will enter the frequency converter along the radiator, thus causing the frequency converter to short circuit or even burn down.
