  More dust and poor water quality in  the chiller environment will affect the normal operation of the equipment, and even lead to downtime. In order to increase the operating power of the chiller, it is necessary to create high-quality conditions for use and effectively maintain the operating power of the  air-cooled chiller . ​ When using the chiller, if there is a lot of dust and other problems in the environment during the operation of the equipment, the normal operation of the equipment will be affected after the equipment enters the water-cooled chiller. In order to prevent the chiller equipment from being affected by dust in the environment and a large amount of scale due to long-term lack of maintenance, companies need to conduct professional inspections on chillers on a regular basis. A layer of solid or ooze builds up, called fouling, which adds additional fouling thermal and flow resistance, increasing required heat transfer area, power consumption and maintenance cleaning c

 The  water-cooled chiller system  is an industrial cooling system composed of a water-cooled chiller, a water tank, a water pump, and a cooling tower. The water-cooled chiller is based on the cooling method of the condenser, which uses cooling water to take away the heat (cooling tower), rather than the fan to take away the heat, which is relative to the air-cooled chiller. Water-cooled chillers include Packaged water-cooled units, open-type water-cooled units, and screw-type chillers. The water-cooled chiller is composed of a compressor, an evaporator (the evaporator can be a water tank coil, a plate heat exchanger, or a shell and tube evaporator), a shell and tube condenser, an electric control part, and a water pump (can be external, not It is made on the chiller), and the water tank (generally, the box-type chiller will have a built-in water tank, and the open-type chiller or screw-type chiller will need an external water tank). Today we will talk about water-cooled screw chillers

  Water cooled screw chiller   is a water to water chiller which compressor use semi-hermetic screw type. It’s high efficient water chiller system. The cooling water system including a water cooled screw chiller, a cooling tower, a water tank, and 3 water pumps. Water cooled screw chiller is widely used in the industrial cooling system. High pressure failure of the water cooled screw chiller is the common failure when it working. While how to deal with the high pressure failure of the water cooled screw chillers. Blow let’s talk with the Possible causes and solutions of the high pressure. 1. The temperature of the chiller is too high and the condensing effect is not good. The rated working temperature of the cooling water required by the water-cooled screw chiller is 30℃-35℃. The high water temperature and poor heat dissipation will inevitably lead to excessive condenser pressure. Occurs in the high temperature season, the reason for the high water temperature may be: cooling tower fai

  It is understood that the   magnetic bearing chiller   is a new type of centrifuge equipment appearing in the international market. Compare to screw chillerIts main characteristics are fast speed, low noise, energy saving, intelligent management, in line with the trend of green development, and the magnetic levitation technology is in the world's leading level. Magnetic levitation  compressor . bearing sensors detect bearings 6 million times per minute . make sure that the maximum offset of the shaft does not exceed 7 microns Automatic control software can compensate vibration error automatically . bearings up to 48000 rpm, smaller size Only 2a-4a starting current has no impact on the power grid Centrifugal compressor, magnetic bearing without lubricating oil, variable frequency drive, integrated digital control. Magnetic compressor 9 characteristics 1.The unit controls the water temperature to an accuracy of ±0.1 °C, and the general unit temperature is ±1 °C. It can realize the
