Bo Sheng Jiangsu freezer refrigeration equipment _ _ air-cooled chillers

Chiller Common Cause Failure Analysis and Troubleshooting chillers use a long time, it will inevitably have some fault, then we will produce according to the phenomenon of these failures, to analyze the causes of failure, find troubleshooting methods. A, industrial chiller capacity to mobilize for incorrect reasons:..... 1 temperature is too low, the oil viscosity is high; 2 capillary obstruction; 3 capacity control solenoid valve opening blocked; 4 capacity control piston ring wear; 5 content transfer passage obstruction; 6 oil filter blockage; 7 insufficient amount of lubricating oil (oil level less); 8 temperature switch fault system; B, industrial chillers abnormal vibration or noise, this phenomenon reasons The following are several, one may be bearing damage, replace bearings; 2. friction between the rotor and the casing or friction, inspection and repair or replacement of a screw; 3. emit electromagnetic solenoid valve sound, replacement or repair; 4. internal fixed parts loose screws, tighten the screws; 5. internal parts loose, tighten. 6. There is a foreign object enters the compressor, remove foreign bodies. C, when the expansion valve for liquid has been uneven, because: 1 Turn degrees superheat too small, adjust the opening superheat; 2, temperature of improper position or balance pipe location, a reasonable choice of installation location; 3 selection... excessive expansion valve, replace capacity suitable expansion valve. Air-cooled chiller and water-cooled chillers and cooling functions is the same way, the overall structure and operation of the circuit in addition to the condenser, the other part is the same. Air-cooled chiller using fin condenser with fan forced air flow directly away refrigerant heat; water-cooled chiller using shell and tube condenser, cooling water constantly flowing away refrigerant heat dispersed through cooling towers the heat absorbed by the cooling water. Comparison of energy efficiency of heat transfer due to the different temperature, in the same outdoor ambient conditions, air-cooled chiller running than water-cooled condensing temperature is high, so in the same cooling capacity, the power consumption of air-cooled chillers It will be higher. From energy efficiency, it is generally a water-cooled unit cooling capacity than air-cooled unit to be higher than 300 ~ 500 Kcal / h. 20-22 August 2013, China's largest, most professional Chemical Equipment Exhibition - The 5th China (Shanghai) International Petrochemical Technology and Equipment Exhibition (CTEF) held at the Shanghai New International Expo Center. The exhibition representative of China at this stage the most advanced chemical technologies and equipment products and application areas show the most powerful platform to attract the world's 35 countries and regions more than 650 well-known domestic and foreign enterprises gathered in one. Nanjing this year, Bo Sheng Refrigeration Equipment Co., Ltd. & Nanjing Lead Sheng Machinery Co., Ltd. to participate in the International Petrochemical Technology and Equipment Exhibition, on display are widely used in chemical industry chillers, large screw chillers, low temperature refrigeration units, heating temperature control equipment and explosion-proof units, etc., by the attention from all regions and national professional buyers, customers can intuitively feel I am Secretary of quality and technical details of requirements. With customers face to face, we explore the industrial temperature control equipment in chemical equipment in technological upgrading and industry trends, receiving a lot. In this exhibition, we work with a lot of customers to reach the intention of cooperation, but also look forward to more business cooperation in the field of chemical production, promote the development of petrochemical industry.
