The principle of the water-lubricating oil-free frequency conversion energy-saving system is as follows: the pressure value of the pipe network measured by the pressuretransmitter is compared with the set value of the pressure, and the deviation is obtained. The frequency value of the inverter acting on the asynchronous motor is cal-culated by the PiD regulator.The corresponding frequency and amplitude of the alter-nating current output by the inverter get the corresponding speed on the motor. Thenthe air compressor outputs the corresponding compressed air to the gas storage tank,SO that the pressure changes until the pipe network pressure is the same as the givenpressure value, which has obvious energy- saving effect.

Our company produces and sells various stainless steel products, and supports customized production of various non-standard products. Stainless steel products are mainly used in fields such as medicine and universities.
