Notes on the use of Zhengzhou circulating water multi-purpose vacuum pump

Water circulating vacuum pump is also called circulating water multi-purpose vacuum pump, water circulating vacuum pump, circulating water vacuum pump, etc In many industrial processes, such as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum moisture return and vacuum degassing, water ring pump is widely used Due to the rapid development of vacuum application technology, people have been paying attention to the water ring pump in obtaining the coarse vacuum Therefore, Great Wall Instrument Co., Ltd has produced the circulating water multi-purpose vacuum pump As the gas compression in the water ring pump is isothermal, it can pump out inflammable and explosive gas In addition, it can pump out the gas containing dust and water According to the characteristics of small laboratory area, the water ring pump is improved by reducing the volume It has the characteristics of small volume, light weight, beautiful appearance, double surface and double head pumping, Four watches and four taps, the same multi-purpose vacuum pump on both sides, even in the teacher's intuitive demonstration, students can turn on and off on either side 　　 After long-term research and development and continuous technology accumulation, Zhengzhou Great Wall Instrument Co., Ltd has obtained many countries, and has been widely promoted and applied in the fields of chemistry, chemical industry, biology, pharmacy, polymer engineering, etc the circulating water type multi-purpose vacuum pump, diaphragm pump, low-temperature coolant circulation pump, low-temperature constant temperature stirring reaction manufactured by Zhengzhou Great Wall Technology Industry and Trade Co., Ltd More than a dozen series and more than 100 models of instruments and equipment, such as bath, closed refrigeration heating cycle device, rotary evaporator, glass reaction kettle, constant temperature magnetic stirring bath, are deeply trusted by customers Among them, refrigeration series and vacuum series products have been the development of the industry for a long time When using the circulating water type multi-purpose vacuum pump, pay attention to the water temperature not to be too high, because the high water temperature will vaporize a lot in the pump body, which will reduce the efficiency of the circulating water type vacuum pump, and the vacuum cannot be knocked down So the water temperature must be controlled But! Generally speaking, as long as the ambient temperature does not exceed the working environment requirements of the pump, there is no water shortage No problem After the completion of suction filtration, the piston of the buffer bottle shall be opened first, and the vacuum pump shall be stopped to prevent the working liquid of the vacuum pump from entering the suction buffer bottle.
