The cold winter is approaching,but the production cannot be stopped.The cold air has a great impact on the air compressor,so how do we protect the cold air from the air compressor?

1.Improve the environment and working conditions of the computer room

First of all,if possible,put the air compressor indoors or build a temporary tent in winter as much as possible.This can not only prevent the temperature from getting too low,but also improve the air quality at the air inlet of the air compressor and maintain the temperature of the air compressor room above zero.

Secondly,pay attention to keeping the environment clean and tidy.In particular,pay attention to the fact that there is no accumulation of water around the equipment and the ground of the station building to prevent ice and slippage,which may cause the operator to fall and be injured.

2.Improve the operation mode of air compressor

Before the air compressor is used,we must open the side cover to observe whether the oil thickens or freezes.If so,the oil must be heated first.Even if the oil is not frozen,the oil viscosity of the lubricating parts of the unit is relatively high when the unit is just turned on in winter,and the voltage of some outdoor work sites is relatively low,which may cause relatively difficult startup when the unit is first turned on.The general method is to first turn the unit 2-3 times,start the air compressor 3-4 times,and then load the unit after running for a period of time.The current of the air compressor can be measured with a multimeter after its normal operation.Normally,it is within 5% of the rated current of the motor.If it exceeds 10% of the normal current,the unit has a problem or the voltage is low.It should be shut down for inspection.Otherwise,the motor will easily heat up and burn out,and will also waste electricity.An important reason for the high current is that the oil starts to block.

After the shutdown in winter,you must pay attention to venting all gas,sewage,and water,and venting the water,gas,and oil in various pipes and air bags.This is because the temperature of the unit is relatively high when the unit is working in winter.After the unit is shut down,because the outside temperature is low,a large amount of condensate will be generated after the air is cooled.Intercooler blockage,air bag swelling and cracking and other hidden dangers.

At the same time,after the cold air enters the air compressor,it will produce a lot of water vapor when it encounters high temperatures,which will increase the burden of the air compressor's post-treatment,so it is necessary to frequently discharge the water in the post-treatment equipment.

Compressed air enters the production area through pipes and is used by users.Some of these pipes are buried in the ground,and some exposed pipes are erected in the air.Exposed pipes in cold weather may cause part of the humidity to be generated due to low temperature,and some may even increase the humidity,which will have a certain impact on the normal use of users.For example,in the laser cutting machine industry,if the compressed air contains high oil and water content,it will affect the accuracy of the cutting process.In the mining industry,humid air compressor compressed air may not affect the normal use of pneumatic tools,but it will affect the strength of pneumatic tools during operation.

Therefore,when off work in winter or when the equipment is shut down,drain valves such as pipes,gas storage tanks,and dryers should be fully opened,and the condensed water should be drained before closing the valves.
