Silicone Crank Case Heater Element Factory for Compressor

The matrix of the compressor crankcase heating belt is a long belt, with a narrow groove in the middle of one side, the resistance wire is wound on the glass fiber above the wire, through the matrix hole, the wire and silicone rubber wire are connected with the copper clip and the silicone rubber is sealed into the end of the heating belt, and then the retracting hook is fixed on the end with rivets, and the retracting spring is installed on the retracting hook, and the other end is pulled when used The spring connection is set around the crankshaft, and after electricity, the oil is softened by heat, so that the compressor is easy to start.

After the compressor is shut down for a long time, the lubricating oil in the crankcase will flow back into the oil pan, causing the lubricating oil to solidify, and then affect the lubrication performance. To avoid this, compressors are usually equipped with crankcase heating belts. The role of the crankcase heater belt is to keep the lubricating oil in the crankcase at the appropriate temperature by heating to ensure the fluidity and lubrication effect of the lubricating oil.

The opening temperature of the air-conditioner crankcase heater is generally set at about 10 ° C, which is because the viscosity of the lubricating oil will increase sharply below 0 ° C, and the fluidity will become worse, and better fluidity can be achieved above 10 ° C. When the temperature reaches the set value, the heating belt will be turned on until the temperature of the lubricating oil in the crankcase reaches the appropriate range.
