呢？ How to choose a low-temperature coolant circulation pump ? First of all, the temperature range to be used must be determined. The temperature required for different tests is different. The lower the required temperature, the more expensive it is. The second is to determine the volume of the cooling liquid. The more cooling fluid there is, the larger the amount of cooling is, and the more expensive it is; after the zui is to see if the environment where the cooling water pump is used is corrosive? If there is, use a stainless steel shell, if not, use engineering plastics.
In general, the lower the temperature of the low-temperature coolant circulation pump, the more expensive it is, and the larger the volume, the more expensive it is. The price of stainless steel casing is more expensive; otherwise, the price is relatively cheap; therefore, you must pay attention when buying. Take the Great Wall Instrument's DLSB-series cryogenic cooling circulation pump as an example:
，是采用机械制冷的低温液体循环设备，可提供恒流恒压循环冷却液体，以满足电子显微镜、电子探针、超高真空溅射仪、X光机、激光器、反应釜、加速器等用来降低仪器工作温度的需要。 DLSB-series cryogenic coolant circulation pump uses DLSB-series cryogenic coolant circulation pump , is a low-temperature liquid circulation equipment using mechanical refrigeration, can provide constant current and constant pressure circulating cooling liquid to meet the electron microscope, electronic probe, ultra-high Vacuum sputters, X-ray machines, lasers, reactors, accelerators, etc. are required to reduce the working temperature of the instrument. For instruments that need to be cooled with constant current and constant pressure water when the water source is insufficient, the water quality is poor, or the temperature is relatively high, this machine is an essential device to ensure the normal operation of the instrument. Can provide low-temperature liquids can be combined with rotary evaporator, vacuum drying box, circulating water multi-purpose vacuum pump, magnetic stirrer and other instruments for multifunctional chemical reaction operations and drug storage at low temperature. This equipment is particularly suitable for various chemical, biological, and physical laboratories that need to maintain low temperature conditions. It is an indispensable equipment for the medical and health, food industry, metallurgical industry, and research institutes of universities and colleges.
的特点： Features of DLSB-series low temperature coolant circulation pump :
1. It adopts compressor refrigeration and intelligent control system, and has various protection devices such as time delay, overheating, overcurrent and overvoltage.
2. The compressor and main components are imported high-quality components to ensure reliability and service life.
3. The circulating pump can output the cooling liquid in the tank (machine), cool or keep the experimental container outside the constant temperature machine, or establish a second constant temperature field.
4. The circulation system is made of stainless steel, which has the functions of anti-corrosion, anti-rust and anti-low temperature liquid pollution.
5. It can provide cooling water that meets the dual requirements of temperature and water quality. It has the characteristics of energy saving, water saving, pollution prevention and scale prevention.
6. The machine and circulating cooling are integrated into one, and the power is reasonable, which fully shows the characteristics of saving space.
7. Some products have meter parameter lock function, which can lock the system parameter setting values. Non-operators cannot change the set parameters at will.
8. All operations are completed by pressing the touch soft key on the microcomputer intelligent controller, and the operation is simple and intuitive.
9. The product is easy to use and can work continuously.
