Shenzhen Guanglong Technology Co., Ltd.-- is a refrigeration equipment manufacturing company integrating design, development, production and sales. Specializing in the production of industrial chillers and related refrigeration equipment, the screw-type chillers have been divided into single compressor heads and double compressor heads through the refrigeration industry manufacturing standards and ISO9000 quality system certification. The twin-screw refrigeration compressors are energy-adjustable fuel injections. compressor. Its three consecutive processes of inhalation, compression, and exhaust are achieved by periodic volume changes caused by the rotation of a pair of intermeshing male and female rotors in the body. Generally, the male rotor is the active rotor, and the female rotor is the driven rotor. A single compressor utilizes the engagement of an active rotor and two star wheels to create compression. Its three consecutive processes of suction, compression and exhaust are realized by periodic volume changes caused by the rotation of the rotor and the star wheel. So what should you pay attention to when purchasing a screw chiller? Based on years of experience in production and sales, Guangshang Technology has summarized some experiences and shared it with you! 1. The main control parameters of the screw chiller are the refrigeration performance coefficient, rated cooling capacity, input power and refrigerant type. 2. The selection of screw chillers should be considered according to the cooling load and application. For refrigeration systems with long periods of low load operation, a multi-head piston compressor unit or a screw compressor unit should be used for easy adjustment and energy saving. 3. When using a screw chiller, priority is given to units with higher coefficient of performance values. According to statistics, the general screw-type chillers operate under 100% load for about one-fourth of the total running time. The percentage of running time for 100%, 75 percent, 50 percent, and 25 percent of the total operating time is approximately 2.3%, 41.5 percent, and 4 percent. 16. Therefore, when selecting a chiller, priority should be given to models with a flatter efficiency curve. At the same time, the adjustment range of the chiller load should be considered when designing and selecting. The multi-head screw chiller has excellent partial load performance and can be selected according to actual conditions. 4. When using a screw chiller, pay attention to the conditions of the nominal working condition. The actual cooling capacity of the chiller is related to the following factors: a cold water effluent temperature and flow rate; b cooling water inlet water temperature, flow rate and fouling coefficient. 5. When selecting a chiller, pay attention to the normal working range of the unit, mainly because the current limit of the main motor is the current value of the shaft power under nominal conditions. 6. In the design selection, it should be noted that under nominal operating conditions, the outlet temperature of cold water should not exceed 15 °C, and the outdoor dry bulb temperature of air-cooled units should not exceed 43 °C. If it is necessary to exceed the above range, it should be understood whether the range of use of the compressor is allowed, and whether the power of the main motor is sufficient. In addition, by the way, the advantages of the next billion screw screw chiller in the industry are widely used. The company uses Laficon/Japan Kobelco/Taiwan Fusheng/Hanzhong semi-closed screw compressor and imported twin screw compressor. . Double screw 5:6 gear ratio and advanced line design, energy saving and efficient. Efficient valve energy control for grading or stepless control. Balanced design, running quietly and smoothly. The moving parts are strictly treated, the oil balance block of the special exhaust is designed, the maintenance period is long, and the trouble-free operation is more than 40,000 hours. High-efficiency oil separator, the exhaust gas output is less than 1.5%, which effectively improves the heat exchange between the two devices, and is more energy-saving and durable. Secondly, all the units of the 10 billion brand screw chillers passed the safety test system 100% test before leaving the factory to ensure that the performance of the unit meets the standards, and the various performance tests are completed before leaving the factory, charging the refrigerant and lubricating oil, and the wiring customers only need to connect. The outlet pipe and power supply can be operated, reducing installation time and cost. EVA sponge pad http:// Chemical Reactor
