Promote the development of science and technology of the times more machinery instead of labor, the rise and prosperity of the compressor industry has also led to a lot of the development of industry, oil-free screw air compressor models as one, in today's very epidemic. Whatever the model user must pay attention to the displacement of purchase options, often displacement parameters to be greater than the actual displacement, it is going to be influenced by other factors. Then factor oil-free screw compressor displacement, what does? Factors actual oil-free screw compressor displacement: 1, temperature. Ambient temperature affects the amount of intake air, at the same volume, the higher the temperature, the smaller the density of the air, the less displacement; opposite the lower the temperature, the greater the displacement. 2 speed. Is proportional between oil-free screw compressor speed and displacement, and factors affecting the speed of the main grid voltage and frequency. 3, the leak. Between the compressor rotor and the rotor housing in the rotation when it is not in contact, there will be a gap in the middle air compressor parts, resulting in leakage. 4 loss. Compressed gas delivered to devices, there will be a period of piping, pipe bend over, pipe length, will want a certain amount of compressed air loss. 5, the cooling effect. Air compression process, the temperature will rise, expansion and contraction principle of the cooling effect is poor, reducing the displacement. Of course, the factors affecting the actual oil-free screw compressor displacement is far more than that, to remind the user when sorting machine, take this into account, to avoid displacement during the subsequent lack of use, and keep up with the production of situation. Sometimes our operators will find that in the case of the engine is running, the air compressor to inflate cylinders, pneumatic reach barometer indicating the value of the initial pressure. That is, insufficient pressure compressor performance, why is there such Xianyang compressor imagine it may be several reasons for this failure and specific solutions:? 1, may be the barometer failure. Observe the barometer, if indicated pressure enough to allow engine speed operation for several minutes, still no pressure rise or rise slowly depress the brake pedal when the air compressor, deflated sound very strong, indicating that the barometer has been damaged, and this barometer should be repaired. 2, the transmission belt between the compressor and the engine is too loose or slipping compressor to the line between the gas tank ruptured or leaking joints. Check the compressor belt is too Sonko Myrtle air compressor, air compressor from the gas tank to the intake manifold control valves, fittings for loose, broken or leak place. 3, oil-water separators, piping or air filter clogged excessive sediment. Should check the oil-water separator is not too much dirt in the air filter and piping and lead to blockage, if it is clogged, you should remove the dirt. 4, compressor discharge valve piece Mifengbuyan, spring is too soft or broken compressor cylinder head bolts loose, trachoma and cylinder head gasket leak and washed out. Check the compressor discharge valve leaks, the spring is too soft or broken, and so to replace or repair damaged parts of the fault based on the look out. 5, the compressor piston and cylinder liner and piston ring wear off even leak. Check the compressor cylinder, piston ring for excessive wear. These are the five factors that lead to insufficient pressure, if you find that you have insufficient pressure compressor, it can immediately carry out more checks. Can give you the best advice.
