The use of cryogenic coolant circulation pumps abides by 9 principles

Shanghai Haozhuang Instrument Co., Ltd. has developed the LNB brand low-temperature coolant circulation pump, which is energy-saving and environmentally friendly, leading the country. Professional manufacturing is more secure and affordable

The low-temperature coolant circulation pump is especially suitable for chemical, biological, and physical laboratories that need to maintain low temperature and normal temperature conditions. Necessary equipment for laboratories.

Precautions for use

1. Before using the low-temperature coolant circulation pump, liquid medium (pure water, alcohol, antifreeze is also acceptable) should be added to the tank. The medium liquid level should not pass through the cooling coil in the tank and should be 20mm below the worktable.

2. Power supply: 220V50Hz, the power supply should be greater than the total power of the instrument, the power supply must have a good "ground" device;

3. Avoid acid and alkali materials from entering the tank to corrode the coil and the liner.

4. The instrument should be placed in a dry and ventilated place with no obstacles within 300mm around the instrument;

5. Always pay attention to the liquid level in the observation tank. When the liquid level is too low, the liquid medium should be added in time

6. When the working temperature of the low-temperature coolant circulation pump is low, care should be taken not to open the upper cover and do not enter the tank with your hands to prevent frostbite;

7. After use, all switches are turned off to cut off the power supply;

8. When the liquid is circulated outside, the customer should pay special attention to the firmness of the connection of the outlet pipe to prevent it from falling off to prevent the liquid from leaking out.

9. The instrument should be cleaned regularly, if not used for a long time, empty the medium in the tank, and wipe it clean to keep the work surface and operation panel clean.

Artificial turf, or synthetic turf, is a man-made (something made by humans) surface made from synthetic materials, made to look like natural grass. It is most often used in arenas for sports that are normally played on grass. However, it is now being used on lawns and in commercial applications as well. The main advantage of artificial turf is low cost of maintenance as there is no need to water it and trim it. Artificial turf have some downsides to, like requirement for cleaning, toxicity and limited lifetime. Artificial turf is extremely popular in sporting industry - especially in US and regions where weather make it difficult to sustain high quality live turf.
