  If the chiller is used for too long, some impurities will inevitably exist inside, which will affect the refrigeration system. In order to ensure the stable cooling effect of the chiller and prolong the service life of the chiller, regular maintenance of the chiller is required. So, what are the requirements for pipe cleaning of   screw chiller system ? Observe that the oil color of the compressor refrigerating oil of the screw chiller turns brown, indicating that the oil has been turbid, check whether the smell has a burnt smell, and check the resistance value of the motor winding in the compressor. If the resistance between the windings and the casing is normal and well insulated, the refrigerating oil and cleaning system must be replaced. For the contamination in the system pipeline, the cleaning agent can be used to clean it. Before cleaning, first discharge the refrigerant in the refrigeration system, then remove the compressor, and pour the refrigerant oil from the pro...

  1. In order not to affect the cooling effect of the   air-cooled screw chiller , to ensure the normal and continuous operation of the plastic equipment. Please place the chiller in a clean, well-ventilated place with good heat dissipation (it is recommended to place it outdoors with a sunshade, and there is no large heat source in the space within 2M of the equipment). 2. Please clean the condenser regularly. It is best to use gas of no less than 0.8Mpa (usual nitrogen) or a soft brush to clean the dust on the condenser fins (blow perpendicular to the fins to prevent the fins from blowing Inverted), in order to avoid the poor heat dissipation of the condenser during long-term operation of the equipment, resulting in high-pressure protection of the chiller, and the compressor does not start, which may affect customer use. 3. Please remind customers to clean the water tank regularly and change the water frequently. Generally, the pure water is replaced once a month, and t...

  With the development of the refrigeration industry, the application of chiller refrigeration technology has become increasingly widespread. Water chillers  are widely used in plastic injection and blow molding, metal processing cutting oil, welding equipment, die casting and machining, chemical processing, pharmaceuticals, industrial processing equipment, food, and beverage processing, paper-making, cement processing, vacuum systems, X-ray diffraction, analysis equipment, semiconductors, compressed air and gas cooling, etc. 1. Clothing inventory chiller: processing clothing, clothing production, and workshop cooling, initial cooling of service processing equipment, clothing inventory, and other series of cooling control the temperature, humidity, and cleanliness of the environment to varying degrees. 2. Food ice water machine engineering Perishable food must maintain a stable low-temperature environment during the entire circulation process from purchasing or fishing, proces...

  What to do with the low-pressure alarm of the chiller? First, the low-pressure failure of the water chiller is due to the compressor suction pressure being too low. The compressor's normal suction pressure is 0.4~0.6MPa. When the suction pressure is lower than 0.2MPa, the low-pressure protection relay will act. If it is too low, the return air volume is lacking, and the cooling capacity cannot meet the requirements, which will cause unnecessary power loss. Therefore, the   water-cooled chiller factory   is here to talk about the six possible reasons for the low-pressure alarm: 1. Check whether the temperature of the cooling water is too low. When the outside temperature is too low, the cooling water is turned on and running at low temperatures; or the temperature of the refrigerating oil is too low, and the refrigerator cannot be completely separated, which will cause low-pressure failure. If the temperature of the cooling water is too low, shut down the cooling tower o...

  After many customers purchase the required  industrial water chiller , they often ignore some basic aspects of the refrigeration unit water pipe during the installation and construction process. Today, a few key points of the construction, installation, and purchase of the refrigeration unit water pipe are briefly explained. Everyone knows that many plastic products factories, mold cooling in the plastics industry, electroplating tank cooling in the electroplating industry, ultrasonic cleaning fluid cooling, various cooling in the chemical industry, various cooling in the food industry, and many other industries will be useful for refrigeration units, so how do you get the right pipes after you buy a refrigeration unit? I want to tell you some simple methods for selecting water pipes for refrigeration units. Hope to be of some help to my friends: 1. Pay attention to the heat preservation and moisture prevention of the water pipes. The heat preservation of the inlet and outle...

  In this article, the   air-cooled chiller manufacturer   will explain in detail the installation steps of industrial chillers and some simple daily maintenance tasks. I hope it will be helpful to everyone. Simply put, the installation process of industrial water chiller is roughly divided into the following 15 steps: 1. Please check whether the chiller is damaged before installation, and choose a suitable place to facilitate the chiller installation and future maintenance. 2. The installation site must be the floor, installation mat, or level foundation, the level of which is within 6.4mm and can bear the operating weight of the industrial water chiller. 3. The chiller should be placed in a computer room with a room temperature of 4.4 to 43.3 degrees. There should be enough space around and above the industrial water chiller for routine maintenance. 4. At one end of the industrial water chiller, there should be a space for cleaning the condenser tube bundle. You can als...

  1. The temperature difference of the standard water chiller is 5 degrees (20 degrees drop 15 degrees) if a 10HP water chiller has a standard chiller flow rate of 5 cubic meters per hour. 2. When you try this chiller, you can't just look at the flow rate of the chiller, but also how much temperature you need. If the temperature you tried was dropped from 28 degrees to 7 degrees, if you try the chiller If the temperature difference is large, then the hourly chilled water flow will be reduced from 3.5 cubic meters to more than one cubic meter. Then if you need 5 cubic meters per hour, you have to choose a larger chiller. 3. When trying out the chiller, it depends on whether you are cooling directly or indirectly. Direct cooling is to feed water directly into the chiller, and the frozen water will directly cool the product you need, so the effect will be better, then Indirect cooling, for example, put water in a basin, put a small basin on top of the basin, and put the product to be ...
