Water ring vacuum pump for dyeing and finishing process
In the use of water ring vacuum pump, the normal make-up water is supplied from the main water supply pipe of the pump. Under different working conditions, the make-up water quantity is different. In the process of water replenishment, if there is less water replenishment, the compression heat in the pump cannot be fully discharged, and the temperature of water ring and gas will rise, resulting in the decrease of air volume and vacuum degree of the vacuum pump. If the water volume is too small, the loss of the water ring can not be supplemented, which not only further reduces the performance, but also stops working because the water ring cannot be formed. For example, there is a large amount of supplementary water, too much water, which makes the water ring thickened and the real gas volume and exhaust pressure reduced. At the same time, too much water will increase the consumption of motor power, reduce efficiency, generate noise and vibration. Make the water ring vacuum pump work very unstable, and will discharge a lot of water from the exhaust port. In the use of water ring vacuum pump, whether the water supply is too large or too small, it will directly affect the performance of water ring vacuum pump and reduce the efficiency of water ring vacuum pump.
Water ring vacuum pump is used in papermaking, dyeing and finishing processes. In addition to the normal water supply pipe, a large amount of water will be sucked in from the suction port, and users often do not pay attention to the adjustment of water ring vacuum pump.
At present, the working fluid of water ring vacuum pump is used circularly in modern paper factory and dyeing and finishing factory. In the use environment, if the enterprise does not do well in filtration and cooling, the viscosity of working water will increase, the water temperature will rise, and the efficiency of water ring vacuum pump will decrease;
In addition, there is more water in the suction gas, which will reduce the air volume of the water ring vacuum pump, significantly increase the shaft power and make the vacuum pump unstable in a certain range, and the more the water, the more the impact.
In addition, there are a large number of fibers, fillers and various chemical AIDS in the gas and water pumped from paper making and dyeing and finishing, which lead to the annual large working fluid, high temperature, and deterioration of circulating water quality, resulting in scale, blockage, corrosion, wear and other bad consequences, further reducing the performance of water ring vacuum pump, and making the motor appear heat and overload Condition.
1. Select high-quality water ring vacuum pump, because different quality water ring vacuum pump first has different proportion of ingredients in raw materials, and different casting process. In addition, high-precision processing, assembly and other processes are required to jointly determine the performance and stability of water ring vacuum pump;
2. Do a good job in the control of filtering and suction water, reasonably control the water coming from different ways during the work, and select the front steam water separator with reliable quality and reasonable rationality, and regularly check to ensure its normal operation. ;
3. Regularly check whether the working current of the water ring vacuum pump is abnormal, and rectify in time if there is any problem;
4. Pay attention to the water quality of water ring pump vacuum pump; etc
