In order to ensure that the cooling machine does not damage the key components such as the compressor during the working process, the high voltage, low voltage protection and phase protector of the cooling machine are simultaneously connected to the control loop of the electric control box. When a certain part fails, The control loop will automatically disconnect the AC contactor and turn off the main power supply of the main unit to protect it. The connecting pipe system mainly consists of high and low pressure connecting pipes and thermal expansion valves. The expansion valve is connected in series in the high and low circuits, close to the evaporation coil, in order to control the flow of Freon entering the evaporation tube. The temperature-sensing water of the thermal expansion valve is connected to the low-pressure pipe, which can automatically adjust the size of the expansion valve according to the temperature of the return pipe to control the proper freon flow to achieve the best cooling effect. The size of the thermal expansion valve depends on the cooling capacity of the cooling machine and the evaporation temperature of the evaporation coil in the solution. Too large or too small will directly affect the cooling effect.

The electroplating solution cooler with the air conditioner compressor (ie high temperature compressor) as the main unit can fully meet the cooling requirements of the electroplating solution as long as the appropriate condenser and cooling tube are selected. The selection of the material and length specification of the cooling pipe is directly related to the rationality of the system and the cooling effect. If the lead-bismuth alloy is used repeatedly, the pipeline has insufficient pressure resistance and bursts, so that the solution is sucked into the compressor and the condenser, causing damage to the main engine. . The airtightness test and the withstand voltage test of the cooling pipe are strictly prohibited by the water pressure test. Otherwise, the residual water vapor in the pipeline will condense into water after the cooler is working, and then freeze, thereby blocking the expansion valve and causing blockage of the pipeline. Low-pressure protection of the refrigeration system affects the normal operation of the chiller.

Machining Aluminum

Aluminum machining is the use of CNC machining out, including: drilling, boring, cutting, turning, screw. Product material are: aluminum6061,6061-T6,6063,6083,7075.5052,2017 .In the high-speed machining out of the workpiece has a good finish. Aluminum machining product surface treatment has anode, electroplating, sand blasting, laser engraving LOGO, mechanical drawing, rolling flower, according to the requirements of the drawings on the product anode all kinds of colors such as color, black, red, blue, yellow. We have a special inspection department to carry out inspection, to ensure that each size of products meet the requirements of the drawings, machining aluminum(cnc aluminum) is the most common in mechanical processing, low density, not easy deformation, high precision products. So it is widely used in various industries.
