Researchers doing research know that it is often necessary to cool down or warm the instrument with cooling and cryogenic liquids while doing laboratory experiments. Therefore, it is essential to provide a device for circulating cooling water at low temperature. Generally, The use of low-temperature coolant circulation pump on the device cooling or constant temperature. How to buy low temperature coolant circulation pump? 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. In general, the lower the temperature of the cryogenic coolant circulation pump, the more expensive the price. The larger the volume, the more expensive the price. The lower the price of the stainless steel shell, the more expensive it is. Therefore, the time to buy must pay attention. Take the Great Wall equipment DLSB-series cryogenic cooling circulation pump as an example: DLSB-series low temperature coolant circulation pump uses: DLSB-series of low-temperature coolant circulation pump is the use of mechanical refrigeration cryogenic liquid circulation equipment, providing constant current constant Pressure circulation cooling liquid to meet the electronic microscope, electron probe, ultra-high vacuum sputtering instrument, X-ray machines, lasers, reactors, accelerators and other instruments used to reduce the temperature needs. For work in the lack of water, poor water quality or high temperature constant current water pressure required to cool the instrument, the machine is to ensure the normal operation of the equipment necessary equipment. Can provide low-temperature liquid can be combined with rotary evaporator, vacuum oven, circulating water vacuum pump, magnetic stirrer and other equipment for multi-functional low-temperature chemical reaction operations and drug storage. The device is especially suitable for all kinds of chemical, biological and physical laboratories that need to work under the condition of low temperature. It is an indispensable equipment in the laboratories of medical, health care, food industry, metallurgical industry and universities and research institutes. DLSB-series low temperature coolant circulation pump features: 1, the use of compressor cooling, intelligent control system, and a delay, overheating, over-current, over-voltage protection device. 2, the compressor and the main components are imported high-quality components to ensure reliability and service life. 3, circulating pump tank (machine) within the cooling fluid output, cooling or constant temperature outside the experimental vessel or to establish a second temperature field. 4, the circulatory system uses stainless steel, with anti-corrosion, rust, anti-cryogenic liquid pollution function. 5, can meet the dual requirements of temperature and water quality cooling water, with energy saving, water saving, pollution prevention, anti-fouling characteristics. 6, the machine and cooling in one cycle, the power is equipped with a reasonable, fully demonstrated the characteristics of space-saving. 7, some products have the instrument parameter lock function, the system can lock the system settings, non-operator can not freely change the parameters have been set. 8, all operations are in the microcomputer intelligent controller touch the touch softkey to complete, easy to operate, intuitive. 9, the product easy to use, can work continuously.
