When does the water lubricated single screw air compressor need maintenance?
In Mianzhu, the maintenance of water lubricated single screw air compressor needs to find a professional team. If the air compressor is not well maintained, there will be many invisible problems.
In order to ensure the normal and reliable operation of the water-lubricated single-screw air compressor and ensure the service life of the air compressor unit, a detailed maintenance plan must be formulated, and the fixed-person operation, regular maintenance, and regular inspection and maintenance must be carried out to make the oil-free and silent air compressor The unit is kept clean, oil-free and dirt-free.
main components shall be maintained according to the following table:
note:
a, according to the above table maintenance and replacement of each component must be determined: the pressure in the water lubricated single screw air compressor system has been released, separated from other pressure sources, the switch on the main circuit has been disconnected, and the safety identification of closing is not allowed.
B. The replacement time of compressor cooling lubricating oil depends on the use environment, humidity, dust and whether there is acid and alkaline gas in the air. The newly purchased water-lubricated single screw air compressor shall be replaced with new oil for the first 500 hours of operation, and then replaced every 4000 hours according to the normal oil change cycle. Machines with less than 4000 hours of annual operation shall be replaced once a year.
C, the oil filter in the first boot operation 300-500 hours must be replaced, the second time in the use of 2000 hours of replacement, after the normal time every 2000 hours to replace.
D, maintenance and replacement of air filter or intake valve remember to prevent any debris into the compressor host cavity. When operating, the entrance of the host is closed. After the operation is completed, rotate several circles by hand according to the rotation direction of the host to make sure there is no obstacle before starting the machine.
E. Check the tightness of the belt every 2000 hours or so of the machine. If the belt is loose, adjust it until the belt is tight. In order to protect the belt, it is necessary to prevent the belt from being scrapped due to oil pollution during the whole process.
F, each oil change, must be replaced at the same time the oil filter.
G, replace the parts as far as possible the original company parts, otherwise there is a matching problem, the supplier will not be responsible.
Clean the cooler
the water-lubricated single-screw air compressor runs for about 2000h. In order to remove dust on the heat dissipation surface, it is necessary to open the blowing hole cover of the cooler on the fan bracket, and blow the cooler with a dust blowing air gun until the dust on the heat dissipation surface is cleaned. If the heat dissipation surface is seriously dirty and difficult to purge, the cooler can be removed, the oil in the cooler can be poured out and the four inlets and outlets can be closed to prevent dirt from entering, then the dust on both sides can be blown off with compressed air or washed with water, and finally the water stains on the surface can be dried. Place back in position.
Remember! Do not use iron brush and other hard objects to scrape dirt, so as not to damage the surface of the radiator.
Drain condensate
the moisture in the air may condense in the oil and gas separation tank, especially in humid weather, when the exhaust temperature is lower than the air pressure dew point or shutdown cooling, there will be more condensed water precipitation. Too much water in the oil will cause emulsification of the lubricating oil and affect the safe operation of the machine, such:
1, resulting in poor lubrication of the compressor host;
2. The oil and gas separation effect becomes worse, and the pressure difference of the oil and gas separator becomes larger;
3, causing corrosion of machine parts.
Therefore, a condensate discharge schedule should be developed based on humidity conditions.
Condensate water discharge method
it should be carried out after the machine is shut down, there is no pressure in the oil and gas separation tank, sufficient cooling, and the condensed water is fully precipitated, such as before starting up in the morning.
① Screw out the front screw plug of the ball valve at the bottom of the oil and gas separation tank.
② slowly open the ball valve drainage, until there is oil flow, close the ball valve.
③ Screw on the front screw plug of the ball valve.
In the field of air compressor, there are not many manufacturers that can use real frequency conversion motors. Shanghai Granklin Group produces water-lubricated variable frequency air compressors. Through the use of permanent magnet motors and variable frequency controllers, it has achieved the effect of energy saving and emission reduction. General frequency conversion means can suppress frequent loading and unloading of equipment, and can also save a lot of power, improve reliability and reduce noise. If the air compressor uses frequency conversion, it can also stabilize the system pressure.
The use of oil-free water-lubricated air compressors in food, beverage processing, pharmaceutical, packaging, electronic manufacturing, painting, powder coating and textile manufacturing processes must eliminate any risk of contamination, which can lead to serious consequences. Professional oil-free water lubrication screw air compressor completely avoided
What are the common shortcomings of the screw air compressor?(1) When the screw air compressor is shut down, the air inlet is sprayed outward. When the air compressor suddenly stops and does not open the exhaust valve in time to discharge exhaust gas, the air inlet sprays cooling oil outward. At this time, first check whether the intake valve has defects and cannot be closed normally. Second, check whether the oil cut-off solenoid valve has defects. Assuming it is normal, further check whether the check valve on the main exhaust pipe can be closed in time or completely. If there are defects, it should be removed.
For oil-free air compressor, most people will think that the air compressor uses air compressor oil during operation and adopts post-processing filtration to remove oil. In fact, this is one of our misunderstandings about oil-free air compressors. Air compressor oil has many functions, including cooling and lubrication. The so-called oil-free air compressor of Granklin air compressor uses water lubrication, and the compressed air is 100% oil-free.
Shanghai granklin group is engaged in the production and processing of oil-free and water-lubricated air compressors. we are focused on the production of screw air compressors. doing a good job in water-lubricated air compressors can make mechanical failures lower and users feel more at ease in using gas. On the use of the effect to see the screw air compressor has the following advantages.
Buy products preferred big brand, good service quality manufacturers. From foreign to domestic, there are only a few enterprises that can make water-lubricated air compressors in the screw air compressor industry. "Shanghai granklin Group" is one of them. granklin Do not forget your initiative mind strove forward on the road of water-lubricated air compressors.
The main engine of the air compressor is the core part of the air compressor. It has been in a state of high-speed operation for a long time. Since the components and bearings have their corresponding service life, preventive main engine overhaul must be carried out after a certain period of time or years of operation. In general, it is mainly required for the following 4 items
No oil and water lubrication screw air compressor which good quality recommendation, in recent years, in response to the national call for energy conservation and emission reduction, Shanghai granklin group is committed to the compressed air system for customers, to provide quality energy-saving solutions. 1. without oil and water lubrication screw empty
Energy conservation and environmental protection is always advocated by our country, and the R & D teams of manufacturing enterprises are also trying to develop energy-saving equipment. The screw air compressor, as one of the important gas equipment for production enterprises, will inevitably cause environmental pollution in the process of use.
Enterprises in the purchase of air compressor, facing in the frequency conversion air compressor and power frequency air compressor two choose one situation, in the process also need to consider the air compressor is to choose no oil, oil, or micro oil, what is the difference between the three. Air compressor is a mechanical equipment that provides power for the production line, which can be used in various production industries such as textile, laser cutting, and medicine. Although many production industries need air compressors, different industries have different requirements for air compressors.
