When does the oil-free air compressor need maintenance?
The maintenance of oil-free air compressors in Pingwu County requires 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 oil-free 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 keep the oil-free silent air compressor unit 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 oil-free air compressor system has been released, separated from other pressure sources, the switch on the main circuit has been disconnected, and the safety mark of not closing has been made.
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 oil-free 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. The machine with annual operation less than 4000 hours 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
in order to remove the dust on the heat dissipation surface after the oil-free air compressor runs for about 2000h, it is necessary to open the blowing hole cover of the cooler on the fan bracket, and blow the cooler with a dust blowing 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.
High-end air compressors are basically monopolized by foreign brands, mainly: the price of the whole machine of major international brands is relatively expensive. Domestic products such as: granklin is not bad, the price of the whole machine is relatively cheap
It is recommended that you consider these comprehensive factors when buying air compressors: price, use, gas production, and after-sales service. Imported brands are more expensive than domestic air compressors, but the cost performance of domestic brands and
The application industries of water-lubricated air compressors produced by Shanghai Granklin Group: university laboratories, chromatographic analysis, medical pharmacy, dentistry, food processing, construction engineering, chemical industry, machinery, environmental protection, meteorology, hydropower, spraying, sandblasting, PET Bottle blowing, leak detection, metallurgy, water treatment, printing, shipping, textile, petrochemical, electronics, instrumentation, tobacco, nitrogen production.
Granklin screw air compressor without oil and water lubrication 1. The oil-free design adopts water lubrication, the design of all stainless steel main machine and high-precision processing technology make water become the core of the well-deserved oil-free compressor; 2. The main machine adopts medical 304 stainless steel precision high-pressure casting, which will never rust; 3. Fully computer-controlled automatic water supplement system, all-round system operation detection, and completely oil-free exhaust quality, let the oil-free air flow;
View detailsIn the field of food production, the quality of compressed air is directly related to food safety and product quality. In view of the problem of "whether the air compressor in the food factory can use the micro-oil air compressor", it is necessary to advance from the aspects of food safety risk, regulatory requirements and industry practice.
The purchase of air compressors has corresponding standards according to different industries. Oil-free air compressors are generally used in some industries with higher air quality requirements. Laboratories and medical industries belong to them. For laboratories, oil and gas in oil air compressors will affect valves, nozzles and pollution.
There are several possible reasons for the overload of air compressor: 1. The main engine or motor is blocked or the bearing is damaged. 2. The power supply voltage is too low. 3. Missing phase operation. 4. Poor contact of the main power supply or contactor. 5. The oil filter or oil-gas separator is blocked.
First of all, answer the main question: the food industry with oil-free compressor is not necessarily good. This should first remove several aspects of compressed air used in the food industry. Compressed air used in the food industry is divided into three types according to whether it is in direct contact with food: 1. Direct
The precision equipment used in the laboratory requires relatively high gas, and "oil-free compressed air" is a necessary gas. "Water lubricated air compressor" is one of the essential equipment. In the process of laboratory construction, the gas used in different laboratories is diverse.
1. operators must be familiar with the structure, performance, working principle, operating procedures and precautions of the air compressor. 2. operators must undergo technical training and safety training, and after passing the examination, they shall take up their posts with certificates and shall not operate without certificates.
