Industrial chillers are widely used in a variety of industrial production - 1. Chemical (scholar) industry 2. Plastic products, plastic containers, film making, plastic steel profiles, pipes, wires, cable sheathing, tire industry 3. Electroplating and machine cutting fluid Cooling industry 4. Pharmaceutical industry 5. Electronics industry 6. Hardware industry 7. Food and beverage industry 8. Laboratory 9. Medical equipment 10. Optical instruments.
1. The chemical industry is mainly used for cooling and cooling of chemical reactors (chemical heat exchangers), and takes away the huge heat generated by chemical reactions in time to achieve the purpose of cooling (cooling) to improve product quality.
2. In the injection molding process of plastic products (television, computer, washing machine, mobile phone, refrigerator, air conditioner, plastic toy, automobile plastic parts, etc.) in the manufacturing industry of plastic products, plastic containers, food packaging films, medical packaging films, etc., can it be timely Effective cooling (cooling) will directly affect the appearance and appearance of the product, which will affect production efficiency and affect production costs and corporate profits.
The production of plastic containers (blowing bottles) and packaging films is even more inseparable from chillers (ice water machines). If the plastic container cannot be cooled and shaped in the production process, the produced container will not be full, the wall thickness will be uneven, the color will not be bright, and even the molding will not be possible, resulting in low product quality. In the production of packaging film, if there is no cold water (wind) cooling molding, it is impossible to produce a qualified product. Cooling with cold water (wind) provided by a chiller (ice water machine) not only greatly improves product quality, but also increases production efficiency.
3. In the cooling electroplating production of electroplating solution, hydraulic oil and machine tool cutting tool coolant, the electroplating solution generates heat in the electroplating reaction without any part, so that the temperature of the electroplating solution is gradually increased. When the temperature of the electroplating solution is higher than the process requirement, The surface plating of the produced electroplated products has a great influence on the firmness, uniformity, flatness and surface finish of the coating. The choice of the cold water provided by the chiller (ice water machine) to cool and maintain the constant temperature of the plating solution will greatly improve the electroplating production process and production efficiency.
The cooling of the coolant of the machine tool cutting tool and the control of the tool blade temperature will directly affect the tool life and product quality.
4. Pharmaceutical industry The pharmaceutical industry is mainly used for the control of temperature and humidity in the production workshop and the reaction heat in the process of producing raw materials.
5. In the electronics industry, the components need to be kept or cooled at a specific temperature during the production of electronic components, and the performance parameters of the electronic components can be controlled in the design state.
1. Analysis of the cause of high pressure alarm:
1. The cooling water is not open. This problem is very easy to solve, but it is a common mistake. Solution: Please open the water valve.
2. The cooling water flow is too small or the temperature is too high. Solution: Increase the cooling water flow or reduce the water temperature (cooling water allows 21 degrees -38 degrees).
3. Condenser copper tube has many fouling, small diameter and poor heat dissipation. Solution: Clean the condenser copper tube.
4. There are too many refrigerants. Solution: Discharge excess refrigerant (R22)
5. The expansion valve opening degree is too large. Solution: Properly reduce the expansion valve opening degree, press the compressor thermal relay protection REST (RESTET), find out the cause and then restart.
2. Analysis of the cause of low pressure alarm:
1. Insufficient refrigerant. Solution: leak detection, pipe joints have leak points? Replenish the refrigerant after repair.
2. The filter is clogged. Solution: Remove or replace the filter.
3. The copper tube of the condenser has more fouling, smaller diameter and poor heat dissipation. Solution: Clean the condenser copper tube.
