Efficiency is closely related to domestic and foreign users concerned compressor machine gap energy conservation and efficiency differences between screw machine, because the nose is leaking inside cause the compressor efficiency decline. Leakage within a screw head at a specific pressure and lubrication condition is basically constant, that is just about the amount of internal leakage screw air compressor and the intake and exhaust pressure difference and the fuel injection quantity, nothing to do with speed. That is a screw speed is higher, namely displacement, the smaller the relative amount of leakage, the higher the efficiency. But the speed increase will bring lower reliability, carbon tends to increase, increased seal and bearing wear, shortening the life of the machine and other issues. Where the thrust bearing wear caused by changes in the exhaust side of the gap, resulting in rapid deterioration of the efficiency of the machine. Assess whether a compressor before saving, first make sure it's the speed, if it is at 3000 rev / min 2 or above in order to achieve an energy efficiency, this machine is certainly at the expense of reliability, the cost in exchange for energy conservation target . Many foreign clients in the procurement compressor mature, not only concerned about the costs incurred once the purchase and installation, operation and maintenance costs concerns, but also carefully assess the cost of quality. The so-called cost of quality refers to the production loss may be caused by failure of the compressor. Thus, the quality of the cost of attention to domestic users are very different, domestic users rarely seriously consider the cost of quality. The level and extent of the relationship between the temperature of the compressor how cold objects, called temperature. We know from the energy conservation law in the power and heat can be converted to each other, increasing the temperature around the compressor from mechanical friction work, converted from the compression work. For example, a combination of improper or poorly lubricated bearing friction will increase the power and heat dissipation in the form of exchange, so the bearing temperature will rise, and even burn the bush, so the machine can be judged according to the temperature level of the compressor around Quality is good or bad. Ambient temperature and oil temperature high and low have the following effect on the compressor: a suction gas temperature is too high, it will reduce the displacement; 2, the compression process gas temperature is too high, it will increase the power consumption, reduce productivity; 3, the cylinder temperature is too high, valves and piston rings lubricant coke, loss of lubrication, bumped spark risk of explosion, piston rings and bad at the same time make the compressor valve Qin Wei, fillers and other mechanical work, increasing Large air compressor rental wear, poor sealing; 4, the temperature is too high will burn bearings, bearing not even continue to operate; 5, other parts will reduce the mechanical strength even overheating deformation; 6, the oil temperature is too high, it will reduce oil viscosity and reduce the effectiveness of the lubricating oil pressure impact; 7, the cooling water temperature is too high will reduce the cooling effect; 8, the motor, the engine temperature is too high and there will be danger of burned.
