Walk-in cooler special tool (2)
walk-in cooler special tool
When welding the walk-in cooler pipeline, copper pipes of different bending shapes are often used, which will be used at this time The pipe bender processes the copper pipe to make it reach the required state. The refrigeration pipeline of the walk-in cooler often needs to be bent into a specific shape, and in order to ensure the effect of the system circulation, there are strict requirements for the bending of the pipeline. Generally, the bending radius of the pipeline cannot be less than 3 times its diameter, and the inner cavity of the pipeline must not be deformed.
Other special equipment In the process of walk-in cooler maintenance, in addition to pipeline adding tools, the following special tools and equipment will also be used. The vacuum pump is used when vacuuming the compressor and pipeline of the walk-in cooler. The main function of the vacuum pump is to vacuum the refrigeration system of the walk-in cooler, and its specification is 2 to 4L/s (exhaust capacity). The quality of the vacuum pump will directly affect the effect of vacuuming the system, that is, the vacuum degree of the system, and the vacuum degree of the system will directly affect the quality of the walk-in cooler. When the system contains other gases, the high and low pressures in the system will increase, which will increase the load of the compressor and reduce the refrigeration efficiency of the compressor. Especially when the refrigeration system contains more moisture, the harm will be greater. The moisture in the refrigeration system will reduce the insulation resistance of the compressor, and it will corrode the compressor and the pipeline of the refrigeration system. Moisture can also deteriorate the refrigeration oil, causing a series of failures. Therefore, when vacuuming the walk-in cooler refrigeration system, a qualified vacuum pump must be used and all the gas in the refrigeration system must be evacuated.
