The correct use and maintenance of the oil-injected screw air compressor is the prerequisite and condition for ensuring the safe and stable operation of the unit. In the use of the screw compressor, the inlet air filter is clogged, the oil filter is clogged, the exhaust gas temperature is high, and the exhaust air has a lot of oil. The gas valve limiter that caused the accident was mostly cast iron. The valve was repaired and disassembled several times, and a few cracks appeared on the valve limiter. Since the suction valve is subjected to frequent pulse impact of the air flow, the crack of the limiter gradually expands, and finally the limiter and the center screw slip off and enter the cylinder, causing a collision accident. By analyzing the structure, working process and performance characteristics of the unit, improvements were implemented to ensure long-term operation of the equipment. Replace the oil filter; improve the quality of the imported air. There are many reasons for oil in the exhaust air: the oil separator is blocked; the oil cooler is blocked; the oil temperature is high. Replace the oil separator core; replace or clean the oil cooler core and oil circuit; replace the oil. Compared with foreign countries, China started late in the research of high-pressure gas injection technology, and its development is slow; natural resources are not fully exploited; low-injection gas has low experience in developing low-permeability reservoirs, and gas injection technology is not suitable. The requirements of high-pressure gas injection technology in oilfield mines; due to the few gas injection projects on site, it is unable to effectively promote the technological development of gas compressor manufacturing, gas production and recycling. Regularly clean the cylinder water jacket and cooler to remove slime and scale to ensure cooling. Increase the amount of water supplied. If it is found that the compressor temperature is too high due to insufficient water supply, increase the amount of cooling water to reduce the outlet temperature and the corresponding cylinder cavity temperature. Reduce the temperature of the circulating water.
