Analysis of Common Faults of Experimental Instrument Low Temperature Coolant Circulation Pump

Low-temperature coolant circulating pump is used as an experiment commonly used experimental instrument, which can be used with a variety of instruments (rotary evaporator, fermentor, chemical reactor, freeze-drying equipment, biopharmaceutical reactor, etc.).

The experimental instrument has large cooling capacity and fast cooling speed, which greatly improves the working efficiency; the flow of the local circulating pump can be adjusted and customized, which can meet the actual needs of different users; all models of this machine can be at low temperatures according to the requirements of users. With a reasonable amount of cooling capacity, low temperature and container volume. During the use of the instrument, due to improper use or routine maintenance, there are often some such failures. How do we deal with these problems? Below we analyze some actual problems.

1, failure: no temperature display

Possible causes: Check whether the circuit board connection cable is detached, whether the sensor is detached, and whether water is splashed on the circuit board.

Solution: Plug in the cable, dry the circuit board and turn it on.

2. Failure: No cooling or slow cooling

Possible causes: The system has leaks, and the system has dirty plugging.

Solution: Ask a professional to repair.

3, failure: no external circulation

Possible reasons: The circulation pump is blocked, the power box is disconnected, the valve is open, and there is ice formation in the circulation pump.

Solution: Check the cable, remove the blockage, open the valve

4, failure: the whole machine without electricity

Possible causes: Leakage protector protection, fuse blown, power supply phase sequence error

Solution: Adjust the position of two fire wires, replace the fuse, and reset the leakage protector

In fact, experimental personnel should generally strengthen the routine maintenance and maintenance of experimental instruments, not only to extend the life of the instrument, but also improve the efficiency of use. Through the analysis of the common failures of the experimental instrument cryogenic coolant circulating pump, we hope to help everyone work and study.

Akodi supplies Tool Trolley For Workshop. Also, we have mobile dock ramp and Container Loading Ramp for transporting goods on and off trailers. Stationary dock ramp is also popular for warehouse dock application. Furthermore, for narrow aisle, we supply aluminum alloy lifting platform to assist the aerial cleaning or aerial maintenance job to be done more efficiently.

 

Automatic cleaning machine for welding gun: save time, improve efficiency, stable welding quality


In general, we are accustomed to the use of hand loosened gun mouth cleaning, finished and then screwed back. However, this approach is not safe, waste of time, and may be due to the tightness of welding will directly affect the efficiency of finished product quality.
 
    For these reasons, Akodi developed an automatic cleaning machine for welding gun. After programming, the machine will automatically clean the gun. The process will only take less than one minute to achieve a thorough cleaning effect. However it will take up to 10 minutes for the traditional method. It will not only clean the gun nozzle by injecting oil but also cut wires.
