What kind of pressure gauges do you need for repairing refrigerators?
Maintenance of refrigerator needs with a minimum of 3 pressure gauge, 2 pieces of 2.4 kg, a 1.5 meter, pressure for a 6 tube 20-30 cm for the table header and good expansion valve, bell, head table valve is connected with the need to use teflon tape, tied to the wire head on and valve connection table header all together, even after looking for a 8 to 6 of the copper pipe welding, a set of tools to complete, maintenance of refrigerators need tools to cut, expander, welding, solder, sealing device, electronic scales, pressure gauge, fluoride bottles, evacuation tools, it is best to prepare some brass 6 and 8.
At least two, one is low voltage with negative pressure, the other is without negative pressure measurement of high pressure, one end of the refrigerant bottle or not connected, and the other end of the expansion bell mouth of the copper pipe reception test pipeline. When you go to the accessories store, the boss will tell you.
Maintenance of refrigerators requires at least 3 pieces of pressure gauge, 2 pieces, 2.4 kilograms, a piece of 1.5. The refrigerator low pressure gauge can not measure high pressure.1. Maintenance of pressure gauges for refrigerators is a necessary tool for maintenance.2, through the high-low pressure to determine the operation of air conditioning.3. Vacuum system and evaporation pressure are determined by observing low pressure meter when pumping vacuum and charging refrigerant.4. Watch the high and low pressure meter at the same time when the refrigerator is running, and pass the evaporation pressure of the low pressure meter.
