How to Clean the Laboratory High and Low Temperature Integrated Machine?

The laboratory high and low temperature integrated machine is widely used in various experimental equipment in the pharmaceutical and chemical industry. The heat transfer oil is used as the heat transfer medium, and the refrigerant is used as the cooling liquid to realize the temperature control process of refrigeration and heating.

The long-term operation of the equipment will cause scaling on the surface of the condenser, thus interfering with the normal operation of the laboratory high and low temperature integrated machine. For example, users need to clean large pharmaceutical and chemical cryogenic refrigeration units in order to make them work inefficiently or easily damaged, etc.

1. The high and low temperature integrated machine in the laboratory is an integrated device. The refrigeration system and the heating system are installed in the same chassis. This type of equipment is generally installed indoors. The installation location should be as good as possible on a well-ventilated, dust-free and cool stable floor or laboratory table. Avoid In places with droplets and high steam, avoid places where inflow, stagnation, and leakage of flammable gas may occur, avoid places near devices that generate high frequency (high-frequency welding machines, etc.), and avoid places where acid solutions are frequently used.

2. If you want to clean the equipment, you must disassemble it first, because the parts to be cleaned are not easy to see inside the collector. The various components of the refrigeration unit cross each other, and the pipelines are complicated and difficult to disassemble, which is an understanding of the whole structure.

3. After the connection between the cleaning device and the condenser is disassembled in the previous step, find the direction of the water inlet of the condenser and connect it to the water inlet or outlet of the water pump, then use the tool to heat the pipe.

4. Make sure that each step is done well and the pipes are connected, first add clean water to clean for about 20 times, then discharge the sewage and repeat it 3 times. After the cleaning is completed, it is important to add medicine and clean. Of course, his ph The value should be guaranteed to be between 4-5 and maintained for 2-3 hours, drain the potion, and then carry out the flushing of biological residues to keep the pH.

5. After cleaning, install it back in the original form. This is also the main step to clean the laboratory high and low temperature integrated machine. Disassembling the machine can easily lead to damage to the parts.
