Precautions for the use of circulating water multi-purpose vacuum pump

According to the characteristics of the small laboratory area, the bench pump of Great Wall instrument is improved by reducing the volume It has the characteristics of small volume, light weight, beautiful appearance, etc it is a multi-purpose vacuum pump with double meter, double head pumping, four meter and four tap, and the same double side Even if the teacher demonstrates directly, the student can start and shut down on any side After long-term research and development and continuous technology accumulation, Zhengzhou Great Wall Instrument Co., Ltd has won 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 bath manufactured by Zhengzhou Great Wall Instrument Co., Ltd More than 100 models of more than 10 series of instruments and equipment, such as closed refrigeration and 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.
