For refrigeration equipment repair, time is the second step of the general fault maintenance. The first is to suppress (not including the compressor or change tube) in determining the pipeline without leakage, the next step is to fit. There are two commonly used methods: 1, use the vacuum pump. You can also use a compressor to replace the vacuum pump. Time is longer than generator price with the vacuum pump is a few longer, because of the relative likelihood () compressor exhaust two (amount) to some smaller than vacuum diesel engine pump. On the fridge process pipe connected to a job with a pressure gauge valve, one head welding on the compressor, the other end with a liquid pipe connection on the vacuum pump, open the table method (valve) the door, start the vacuum pump or external compressor, start time, when there is no gas discharge vent on the vacuum pump, took over. 2, to use own compressor to itself. This method is very suitable for go out to repair, need not with vacuum pump. The method is: if the filter is on double tail, mouth open work (the original is www.dongfeng-motor.com welding die), start the compressor, there will be a lot of air from the mouth, when the mouth no gas discharge, the mouth with the hand, unplug the power supply. (be sure to pay attention to safety) open the charging the practice to the system such as refrigerating fluid, when the filter working gas discharge. In the mouth of tongs death, gas welding is used after sealing the mouth.????

Add liquid small diesel engine cooling: cooling liquid, add fluid tube, table after the valves are connected, open the charging the practice period of open (loosen) the end of the charging tube when the tube had cooling liquid discharge head, tighten the method of block (LAN). Open the table on the compressor valve, had better add liquid cooling liquid cylinders upside down, ac synchronous generator when the table shows 4 diesel generator set kg pressure, close the charging valve. The refrigerator electricity, then the pressure of the table with the work single phase induction motor of machine down. When the clock stability have a look at the pressure, generally between zero point three to zero point 8 belong to normal pressure. The static plus 4 kg is based on the refrigerator when the low pressure of static pressure is 4 times at work. As the refrigerator working time increased, the temperature in the oven has been falling, filled volume of the normal, running after a period of time on the muffler should meet (knot), temperature and environmental temperature is the same as the filter or a touch more heat for exactly. If acmotortrading.blogspot.com on the muffler by frosted) (cooling fluid add much, off some, open the charging valve slowly, let while observing muffler, see the frost charging valve shut. If a long time running back up the (gas) pipe temperature is not cool or without dew, open the charging valve and adding some refrigeration fluid. Practice has proved that the choice of low voltage motor fuse and maintenance fuse for low voltage motor phase short circuit, single phase short circuit fault and squirrel cage induction motor overload protection device is simple and effective. But if the fuse type and parameter selection, improper or disadvantage in operation and maintenance, also can not meet the expectations of protection.
