Difference between cryogenic circulating vacuum pump and cryogenic coolant circulation pump

Cryogenic circulating vacuum pumps can be used both as a cryogenic coolant circulation pump and a circulating water multiple vacuum pump. Zhengzhou Great Wall equipment production of low-temperature circulating pump has two series of models, according to the needs of users to choose, DLSB-FZ low-temperature circulating vacuum pump is a single form of suction, refrigeration split one dual-use machine controllable temperature -20 to room temperature, Liquid storage capacity of 20L with 2L Rotary Evaporator supporting the use of. DLSB-ZC low temperature circulating vacuum pump set vacuum three table three taps, controllable temperature -10 to room temperature, liquid storage capacity of 20L with 5L Rotary Evaporator supporting the use. DLSB-G1010 low-temperature cycle high-pressure pump for complex and narrow system coolant, suitable for electron probe X-ray microanalyser, electron microscope and other large precision instrument cooling. Buy low temperature coolant circulation pump to pay attention to how to buy low temperature coolant circulation pump it? First of all, we must first determine the temperature range used, different test requirements require the temperature is not the same, the lower the required temperature the more expensive the price; Second, to determine the volume of coolant, the larger the volume of the coolant, The more coolant, so the amount of cooling is also very large, and its price is very expensive; the last is to look at the cooling water pump used in the environment is corrosive it? If you want to use stainless steel shell, if not on the use of engineering plastics on it. Some specifications cryogenic coolant circulation pump can not directly into the liquid cooling bath, only the external cooling cycle. And some specifications of the existing can be directly into the cooling bath cooling, but also an external cooling cycle. Large size with a bath, small size without a bath, like the size of the mainframe computer, customers should also pay attention to the purchase. Low temperature coolant circulation pump failure analysis Cooling speed seems more and more slow, the more obvious when the temperature is higher? Low-temperature coolant circulation pump is very simple to use, but regular maintenance work can not be ignored. There are many problems that appear to be malfunctioning, which is caused by the fact that there is no regular maintenance. The cryogenic coolant circulation pump's own electrical power and the amount of heat the refrigerant takes away from the load will have to be removed from the radiator at the front hood and will be obstructed if the front hood is filled with dust, , The cooling effect will be greatly reduced. In general, under normal conditions of use cooling capacity decline is due to ventilation cooling effect is too poor or caused by the ambient temperature is too high. The use of cryogenic coolant circulation pump found that the noise much larger than the previously mentioned low temperature coolant circulation pump routine maintenance, this issue is also related. We all know that there are very few impurities in the water, that is, distilled water can not be completely guaranteed after adding water tank. For the water circulation of the cryogenic coolant circulation pump, the general temperature is set at 20 ° C, especially suitable for the growth and multiplication of microorganisms. After a long time these microorganisms will block the water filter caused by poor return, the pump will have a lot of noise. Sometimes these microorganisms are attached to the surface of the heat exchanger, resulting in deterioration of the heat transfer effect of the heat exchanger, resulting in a decrease in cooling capacity. Therefore, we must strictly follow the instructions in the routine maintenance work, regular cleaning of the tank, long-term deactivation, keep the tank dry. Zhengzhou Great Wall Instrument Co., Ltd. is a research, development, manufacturing and operation of science and technology innovation-oriented enterprises. After a long period of research and development and constant accumulation of technology, the company has obtained a number of national patents and has been widely promoted and applied in the fields of chemical, chemical, biological, pharmaceutical and polymer engineering. The company manufactures circulating water-type multi-purpose vacuum pumps, Pumps, cryogenic coolant circulation pump, low temperature thermostatic mixing reaction bath, closed refrigeration heating cycle device, rotary evaporator, glass reactor, thermostatic magnetic stirring bath and so on more than 10 series of more than 100 models of equipment and equipment deep By the customer's trust. Among them, the refrigeration series, vacuum series has long been leading the development of the industry.
