Air compressor repair and maintenance

Air compressor is a kind of equipment for producing and conveying compressed air, especially suitable for coal mine, electric power and other places. Compared with other types of air compressors, screw air compressors have the advantages of safety, environmental protection, energy saving, convenient operation, and simple maintenance and repair. At present, it is widely used in China. Especially because of its advanced nature, reliability, and energy saving, it has been widely used in modern industry. The correct maintenance and maintenance of equipment plays a vital role in the service life and operational reliability of screw air compressors. The author of this article, based on his actual work experience, through the composition and classification of Ingersoll Rand air compressor accessories, compressor maintenance and maintenance and other issues, a simple analysis of how to properly maintain and maintain the machine.

Effective maintenance and troubleshooting of screw air compressors is a prerequisite to ensure its normal use. According to the system's demand for compressed air, first analyze the composition and operation of the compressor system, and conduct a large number of field experiments and theoretical studies. Based on this, a set of methods suitable for the daily maintenance of the machine system are proposed.

For example: the air compressor maintenance is very popular with current users of the frequency conversion control system. When the screw air compressor is turned on, the soft start reduces the impact on some electrical and mechanical components, and the rotation speed of the rotating part is most during normal operation. When the time is lower than the rated speed, various related solenoid valves and pneumatic components also reduce their operating frequency and extend the service life of parts. Thereby reducing the failure rate, improving the efficiency of the system, and indirectly reducing the maintenance cost of the air compressor.

Shipbuilding industry application: In addition to providing the necessary power source for the main engine to start and operate, the air compressor also provides convenience for daily production and life. The most basic maintenance work of an air compressor is to replace the valve discs (high pressure, low pressure) regularly or as appropriate to ensure a good working condition of the air compressor oil. The method of grinding the valve disc is the "8" method, so that the valve disc is evenly ground without causing partial abrasion. The grinding valve plate mainly grinds the working surface, and it is not necessary to require a higher flatness on both sides, so as to avoid unnecessary abrasion and waste. The grinding method of the valve seat is also the Zhuzi method. For the valve seat, the ring groove may become shallower and the valve seat may become thinner due to long-term use and wear and tear. Most ships either put the valve seat in such situations or discard it. In fact, the valve with the ring groove becoming shallow and the valve seat thinning can be processed and used again by turning the valve seat on a lathe. Deepen the ring groove, re-grind, you can use it again. The method is simple, but it is very practical. It not only saves the company's spare parts expenses, but also brings convenience to its own work. After the valve plate and valve seat are ground, they are cleaned with air, reassembled, and tested for leaks. Fill the air intake test with diesel oil and observe whether there are oil traces on the reverse side to determine whether the sealing condition is good or bad.

We require the operators in the enterprise to have a detailed understanding of the product specifications, system processes, and the structure and function of each part of the screw air compressor head overhaul, which is conducive to the daily inspection, maintenance and troubleshooting of the equipment.

Doing a good job in the maintenance and repair of air compressor parts is of great significance for ensuring the normal operation of the equipment and avoiding accidents. Including overall maintenance, maintenance and daily maintenance, maintenance and regular maintenance and maintenance. In view of these aspects, specific maintenance content is proposed. There are mainly several common failures, such as insufficient exhaust gas, cooling system failure, carbon deposits, etc. Specific maintenance measures are proposed for the causes of these failures.

Study the detailed information and characteristics of each accessory, formulate a reasonable replacement cycle, do a good job of daily maintenance, and improve the filter element of the air compressor, so as to save maintenance costs and extend the service life of the unit.
