Do the following four steps to avoid high air compressor temperature
Because the air compressor will produce a lot of heat in the process of operation, if the heat can not be dispersed in time, it may lead to high temperature failure of the air compressor, then the radiator is needed to heat and cool the air compressor。The air compressor radiator needs to be regularly maintained, otherwise the dust in the air duct is easy to be blocked. How to avoid the failure of the air compressor radiator, the following four "prevention" must be done.。
1, to prevent insufficient oil or lubricating oil deterioration
Lubricating oil is very important for the normal operation of air compressors, and has the role of lubrication, cooling and sealing。Less oil or lack of oil will lead to an increase in the internal friction of the air compressor, resulting in high temperature failure, and the use of lubricating oil has a certain replacement cycle, which needs to be replaced regularly to prevent the deterioration of lubricating oil and cause failure。
2, to prevent the air compressor working environment temperature is too high
The location of the air compressor installation should choose a well-ventilated, low temperature environment, can not be placed in the open air, can not be placed in a closed environment。If the ambient temperature is too high, the air compressor cannot dissipate heat, and the working load of the radiator increases。
3, prevent oil filter and air filter blockage
The compressed air of the air compressor contains a large number of dust impurities, if the oil filter and air filter are not cleaned in time, these particles will block the filter element, and the lubricating oil can not flow to the position that needs lubrication, resulting in an increase in the temperature of the air compressor, causing failure。
4, prevent temperature control valve failure

The temperature control valve is an important component to control the internal temperature of the air compressor, which can control the temperature of the air compressor in a certain reasonable range. If the temperature control valve fails, the temperature probe cannot monitor the temperature in real time, the air compressor is prone to high temperature failure。

Influence of cold weather on air compressor

   Air compressor is an important component of PSA oxygen/nitrogen production system,Working in cold temperatures will have a great effect on it,Because of the low temperature,The lubricating oil in the air compressor circulation system will become viscous,Affect the service life of the machine,另外,Cold air into the air compressor will encounter heat to produce a lot of water vapor,The efficiency of the molecular sieve in the system decreased。In order to eliminate these problems, it is necessary to regulate the use of air compressors and reduce the impact of low temperatures on equipment。

1, pipeline cold protection because the water in the compressed air will be discharged through the automatic drainage valve, at low temperatures, it may freeze in the pipeline or other parts。Therefore, it is necessary to winterize the electronic drainage valve and piping system。

2. Keep the temperature of the machine room above zero. Use electric heater to raise and adjust the indoor temperature of the oxygen (nitrogen) machine room;Ensure that the ambient temperature of the equipment room is above 0 ° C。

3. Confirm that the working state of the automatic drainage valve is close to work or before the equipment needs to be shut down, fully open the drainage valve of the pipeline, gas storage tank, dryer, etc., and discharge the condensed water air before closing the valve。

4, shutdown time and space press management If you need to shut down the air separation system, you need to check that the gas emission is displayed as 0 on the display screen after the compressor is shut down.0bar, at the same time must close the valve。Then open the automatic drainage valve of the air compressor, gas storage tank and dryer, and close the air and condensate after completely empting。If it is a long shutdown, you must start once a week and repeat the above operations after 3 hours。

In short, in the low-temperature environment of the air separation equipment, we should always pay attention to the operating status of the air compressor, regularly carry out maintenance and maintenance, prevent the occurrence of air compressor failures, and ensure the smooth progress of production。

How can we prevent the air compressor from leaking oil
When it comes to air compressor equipment, people in the industry should know that lubricating oil plays the main effect, without lubricating oil as a support, air compressor will have no way to operate and work normally, but many people will encounter air compressor oil leakage phenomenon when using air compressor equipment, what is the cause?
How can air compressor device not leak oil?
1, the correct device gasket: the gasket between the air compressor accessories plays the function of leak-proof sealing, if the material, manufacturing quality and device do not meet the technical specifications, oil leakage can be formed。
2, the correct tightening of the nut: too loose will form the pressure is not tight lining and leakage, too tight will make the metal around the screw hole convex, or will screw the buckle and cause oil leakage。
3, timely replacement of failed oil seal: many parts of the oil seal on the air compressor will be due to improper device, forming a different heart of the journal and the oil seal edge and throwing oil。Some oil seals will lose elasticity due to rubber aging after being used for too long。
4, timely replacement of wear parts: after the use of air compressor accessories wear too much, resulting in high pressure gas in the combustion chamber into the crankcase, forcing oil leakage。
5, to prevent the check valve, air valve blocked: if the check valve, air valve blocked, will cause the temperature inside the box shell rise,Oil and gas filled the whole space,Raise the pressure inside the case,And increase the piston movement resistance,Fuel up,At the same time, because of the effect of the air pressure difference in the box shell,Often causes a weak seal oil leakage。

6, to ensure the sealing of all kinds of tubing joints: the pipe nut used in construction machinery is often disassembled, easy to loose due to the slip wire break, such as the poor accuracy of the two joints, the center line of the two cones does not coincide or the taper is different will cause oil seepage。The cone seal can be repaired by grinding, so that the nut is pressed tightly and firmly sealed。

Air compressor head resistance is too large solution

In the process of operation, there will be different failures, these failures will cause the loss of manpower and money, such as the phenomenon of excessive resistance of the air compressor head, how should we solve it?


(1) Manual turning is a basic detection method for the connection and free rotation of the compressor power parts, transmission parts and linkage parts。By manually turning the compressor before starting, check whether the head and motor can rotate freely, and determine whether the rotation resistance increases according to the previous turning experience。

(2) Oil coking in the head is a phenomenon that often occurs when the oil is poor or the temperature is high in the screw compressor. Due to the coking of the head, the gap between the screw or the screw and the star wheel becomes smaller, the friction resistance increases during rotation, the load of the unit increases, and the current increases。In serious cases, the screw and the star wheel are bonded together by oil coke, and the unit cannot rotate freely。
(3) The function of the oil cut-off valve on the head injection pipe is to cut off the injection pipe in time when the unit is shut down to prevent a large number of lubricating oil from being pressed into the head due to the residual pressure in the oil and gas barrel, resulting in too much lubricating oil in the head。Therefore, excessive lubricating oil in the head after shutdown is also one of the reasons for the large starting current of the compressor。The direct way to solve the problem of excessive lubricating oil in the head is to open the head end cover, release part of the lubricating oil in the head, and repair or replace the oil cutoff valve。
