Screw air compressor is a common type of compressor, widely used in various industries and fields. In order to ensure the normal operation of the screw air compressor and extend the service life, daily maintenance is crucial. This paper will introduce the daily maintenance knowledge of screw air compressor to help users master the key skills.
1.Clean and check regularly
Regular cleaning is the basis of the maintenance of the screw air compressor. First, the filter and cooler should be cleaned regularly to prevent the accumulation of dust and dirt from affecting the normal operation of the air compressor. Secondly, to check the cleanliness and oil level of the oil, and replace or add lubricating oil in time. At the same time, check whether the connection of the electrical system is loose, to ensure the normal operation of the electrical part.
2.Pay attention to the operating state of the compressor
When using the screw air compressor, always pay attention to its operating state. Observe the pressure gauge and temperature indicator to ensure that the pressure and temperature are within the normal range. If an abnormal situation is found, such as high pressure or abnormal temperature rise, stop the compressor to inspect in time to avoid further expansion of the fault.
3.Keep the cooling system of the compressor open
The cooling system of the screw air compressor is essential to maintain the normal operation of the machine. Ensure that the supply of cooling water is sufficient, and clean the cooler regularly to prevent dirt accumulation from affecting the heat dissipation effect. At the same time, check the normal operation of the cooling fan, to ensure that the heat dissipation effect of the machine is fine.
4.Replace the filter elements and sealing elements regularly
Filter elements and sealing elements are important vulnerable parts in the screw air compressor, which need to be replaced regularly. The replacement frequency of the filter elements is generally 500 hours or according to the actual use situation. The wear and aging of sealing elements would lead to leakage, so they should be checked regularly and replaced in time.
5.Maintain the air system of the compressor
The air system of screw air compressor includes air inlet, exhaust port and pipe. Regularly check whether the connection of these parts is fastened, and whether the exhaust port has a foreign body blockage, etc. Meanwhile, the air filter should be cleaned and replaced regularly to keep the air system open.
6.Regular repairing and maintenance
In addition to daily cleaning and inspection, the screw air compressor also requires regular repairing and maintenance. Regular repairing includes replacing the lubricating oil, cleaning the cooling system, checking the electrical system, etc. Regular maintenance is carried out by professional technicians, including the replacement of key parts, calibration instruments, etc.
Through correct daily maintenance, it can extend the service life of screw air compressor and improve its working efficiency and stability. At the same time, it can also reduce the probability of breakdown, and reduce repairing and operation costs. Therefore, it is very important to arrange the maintenance plan reasonably and carry out the maintenance operation according to the requirements.
