Q: Oil-free air compressor common faults and maintenance methods?
Answer:
oil-free air compressor common faults include:
leakage: Check whether the gas supply pipeline, one-way valve, safety valve, pressure switch and other joints are leaking. If gas leakage is found, it must be dealt with in time.
Head cup wear: general cup life of about 3 years, expired must be replaced.
Exceeding the rated flow or overloading the machine may also cause the oil-free air compressor to malfunction.
For the maintenance of oil-free air compressors, the following methods can be adopted:
regularly check and replace the air intake filter core to ensure the normal operation of the oil-free air compressor. If the filter core is seriously fouled, it will increase the air intake resistance and affect the air pressure. In addition, it is necessary to check whether the suction pipe has a longer and thinner pipe to minimize the suction resistance.
Check whether the check valve, air valve, etc. are faulty, because the failure of these parts is usually caused by indentation, cracks, spring breakage, etc. on the valve plate. At the same time, check the fastening of the fasteners and the degree of wear of the wear parts, and replace the wear parts.
Check whether the exhaust pressure is normal. Too low exhaust pressure is usually caused by clogging of the air filter, too long suction pipe or pipe cracking, which must be checked and adjusted in time.
Check whether the oil-free air compressor is overheated. If it is overheated, it may be caused by high exhaust temperature, insufficient lubricating oil or insufficient cooling water. In this case, the cooling system must be checked and the lubricating oil or cooling water must be replenished in time.
As an oil-free air compressor, the water-lubricated air compressor of Shanghai Granklin Group also needs to pay attention to the common faults and maintenance methods mentioned above. At the same time, because it uses water as a lubricating and cooling medium, it does not need to use lubricating oil. Therefore, during the maintenance process, it is necessary to regularly check the quality of the water and replace the water to ensure its normal operation and extend its service life.
When there is water in the air compressor, you can take the following methods to deal with: 1. direct drainage method using the drain valve drainage: at the bottom of the air compressor cooler is usually equipped with a drain valve. Once it is found that there is water inside the air compressor, the drain valve should be opened immediately.
The reason why the temperature of the air compressor has been rising may be the following: the surrounding environment of the air compressor has poor ventilation and heat dissipation. It may be that there are other heat sources around the air compressor, which causes the fan to fail to form a strong airflow, so that the air compressor temperature is too high. Air compressor
The main differences between oil-free air compressors and oil-free air compressors are reflected in the lubrication method, compressed air quality, use occasions, energy consumption and maintenance. Lubrication method: oil-free air compressor does not need to add lubricating oil during operation, usually other non-connected
When the air compressor output with water, usually refers to the compressed air contains too much moisture, which may affect the use effect and may cause equipment damage. For the water-lubricated oil-free variable frequency screw air compressor of Shanghai Granklin Group, although it is adopted.
The core requirements of compressed air in pharmaceutical enterprises and the suitability of water-lubricated air compressors in Gilanklin Description 1. The core requirements of the pharmaceutical industry for compressed air In the production process of pharmaceutical enterprises, compressed air directly contacts drugs or is used for power drive in clean areas, and its quality needs to be met.
The amount of moisture in the air is expressed in parts per million (ppm), which is not a fixed value, but is affected by many factors, including temperature, humidity, geographical location and climatic conditions. In the air at normal temperature and pressure, moisture
As the core power source of fermentation process, compressed air runs through the whole process such as strain cultivation, fermentation metabolism and product separation, and its quality stability and supply reliability are directly related to fermentation efficiency and product quality.
The main differences between oil lubrication and oil-free lubrication in compressors are as follows: Lubrication method: Oil-lubricated compressors need to use lubricating oil to reduce friction and wear between mechanical parts. The oil-free compressor uses other non-oil lubrication.
The use time of air filter (air filter) varies due to many factors, including the quality of air filter, the use environment of air compressor and air quality. The following is a detailed analysis of the use time of air compressor air filter: 1. general use period under normal circumstances, good
Answer: The water-lubricated air compressor appears after the screw air compressor, it is a new type of green air compressor. Water-lubricated oil-free screw air compressor Shanghai Granklin Group is specialized in this production.
