Basic troubleshooting of Hot Or Cold Water Cycling Machine
Hot Or Cold Water Cycling Machine is generally recommended to be placed at a temperature of 8 ° C ~ 28 ° C, for laboratories that do not have this condition, must be equipped with the appropriate air conditioner. Continuous professional management and maintenance, qualified units should not punctually send someone to the supplier factory to practice, to obtain more professional maintenance, repair experience and talent.
The condenser should be cleaned once every 3 months. For air-cooled cooling of the compressor, the condenser fan should be repaired on time and the condenser should be decontaminated and dedusted to ensure its excellent ventilation and heat transfer function.
For the compressor to use water-cooled cooling, in addition to ensuring its inlet pressure and inlet water temperature, it is necessary to ensure the corresponding flow rate, and clean the decontamination inside the condenser to obtain its continuous heat transfer function. Punctual cleaning of the evaporator: Because the cleanliness of the sample varies, the evaporator will condense a lot of small particles such as dust under the action of forced air circulation, and should be cleaned on time. The circulating fan and condenser fan cleaning and balancing are similar to the cleaning evaporator. Because the working environment of the test box is different, it should be cleaned on time.
Waterway and humidifier cleaning: If the waterway is not smooth, the humidifier fouling may cause the humidifier to dry, or damage the humidifier, so it is necessary to clean the waterway and the humidifier on time. After each test, the temperature is set near the ambient temperature. After working for about 30 minutes, the power is blocked and the wall of the working chamber is cleaned. When the machine is not used for a long time, it should be energized every half month for punctuality. The power-on time is not less than 1 hour.
The foundation consists of multiple systems of electrical, refrigeration and mechanical, so once the equipment is in doubt, all equipment systems should be inspected and summarized. Generally speaking, the process of analyzing and distinguishing can be first and foremost, that is, after the external elements are first cleaned, the device is first systematically decomposed according to the defect phenomenon.
After the analysis and differentiation of the system summary, or you can use the reverse method to find the disadvantage elements. First of all, according to the electrical wiring diagram to find out whether the electrical system has doubts, after all, to find out whether it is a refrigeration system. Before you can figure out the shortcomings, you must not disassemble or replace parts to prevent unnecessary troubles.
