Gas compressor lubrication system use and maintenance
From;    Author:
Gas compressor failure is the most common piston and piston rings, the rotor parts, abnormal wear at the sliding support and bonding, crosshead slide the bite, fever and other abnormalities. These failures are directly or indirectly, with the lubrication system Lubrication systems and equipment to poor maintenance. As the use of maintenance personnel in addition to study and master the lubrication system and device for the composition of the principle, performance structure, requirements and other general knowledge, but also in practice Continue to sum up the experience accumulated to strengthen the routine maintenance work to ensure that the compressor and lubricating system kept in good running condition. Spot check in daily and periodic maintenance should note the following points: (1) pay attention to maintaining clean oil liquid: oil or dirty oil will cause accelerated deterioration of the vicious circle of worn parts, lubrication of the forced circulation-type system should pay attention to the timely replacement of oil filter clogging and cleaning in place Of the filter; to avoid the oil tank or oil pool exposed to the air to prevent dust and dirt to be mixed with oil, no pressure on the oil tank and air filter can be used to pool the general communication with the atmosphere ;, the overhaul should be From the oil sample testing of its components, such as oil changes to achieve or exceed targets, should all or part replacement and add new oil. Usually every three to six months (or working 2000-4000 hours) can be replaced once the new oil. (2) should be checked regularly: the cylinder should be checked regularly, valves, and exhaust pipes, etc. There is accumulation of solid carbon particles and clay, once discovered should be promptly removed, or may cause the combustion cylinder explosion, increased exhaust resistance , Resulting in abnormal heating. (3) should pay attention to the work of the compressor status: should observe the working status of the compressor, periodically check the wear of lubricating the cylinder valve, adjust the amount of oil, and lubricants to prevent excessive amount of oil shortage Situation. Of the forced circulation system, the lubrication pressure indicator too low or decreased, often to insufficient lubrication, and you should promptly down for maintenance, spare parts and spare parts replaced as necessary. (4) should pay attention to maintaining oil lubrication system: the oil tank or oil in the pool to the normal temperature of 40-50 ℃ appropriate, high oil temperature, oil viscosity reduction, oil-oxidative deterioration of oil temperature is too low, viscosity increases, flow Poor, both of which can lead to inadequate lubrication conditions. Apart from the oil temperature thermometer (dollars) by direct observation, the cold circulating water from the cylinder or the oil cooler cooling water temperature also get an indirect response to the cooling water temperature Too high and too low will affect the oil temperature and oil viscosity.
