After long-term research and development and continuous technical accumulation, Zhengzhou Great Wall Instrument Co., Ltd. has obtained a number of national patents and has been widely promoted and applied in the fields of chemistry, chemical, biological, pharmaceutical, polymer engineering, etc. Zhengzhou Changcheng Branch Industry and Trade Co., Ltd. The company's circulating water multi-purpose vacuum pump, diaphragm pump, low temperature coolant circulation pump, low temperature constant temperature stirring reaction bath, closed refrigeration heating cycle device, rotary evaporator, glass reactor, collector type thermostatic magnetic stirring bath, etc. more than 10 series More than 100 models of instruments and equipment are trusted by customers. Among them, the refrigeration series and vacuum series products have long been leading the development of the industry.
When using the circulating water type multi-purpose vacuum pump, it should be noted that the water temperature should not be too high, because the water temperature is too high, it will be vaporized in the pump body, and the efficiency of the circulating water vacuum pump will be lowered, and the vacuum will not be able to be broken. Therefore, the water temperature must be controlled. but! Generally speaking, as long as the ambient temperature does not exceed the working environment of the pump, there is no shortage of water. There will be no problems. There is also a piston that should open the buffer bottle after the suction filtration is completed. When the vacuum pump is stopped, this is to prevent the working fluid of the vacuum pump from reaching the suction buffer bottle.
Precautions when using Zhengzhou circulating water multi-purpose vacuum pump
The water circulation vacuum pump is also called a circulating water multi-purpose vacuum pump, a water circulation vacuum pump, a circulating water type vacuum pump and the like. In many processes of industrial production, such as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum regain and vacuum degassing, water ring pumps are widely used. Due to the rapid development of vacuum application technology, the water ring pump has been paid attention to in the acquisition of rough vacuum. Therefore, Great Wall Instrument Co., Ltd. has produced a circulating water multi-purpose vacuum pump. Since the gas compression in the water ring pump is isothermal, it can remove flammable and explosive gases. In addition, it can also remove dusty and water-containing gas. According to the characteristics of the Great Wall Science and Industry Trade Bench Pump, the laboratory area is small. Reduced volume and improved, with small size, light weight, beautiful appearance, etc., double-table, double-headed pumping, four-table four-tap, double-sided same multi-purpose vacuum pump, even in the teacher's visual demonstration, students can also arbitrarily Turn it on and off.
