Q: How is diesel generator on the water right and deal with the leaking?

A:Diesel generator set because of the external environment temperature is too low, cooling water should be in a downtime for the decrease in 15 minutes after the water is warm, but not immediately, otherwise it will be because of the fuselage and the external environment temperature difference is too big, cause diesel generator set some of the components deformation, thus influenceThe use of the diesel engine performance(such as cylinder head deformation, etc.).

Open drain will not drain switch after everything is all right, but should also pay attention to the observation of water flow, to see if the water is smooth, if there is the phenomenon of water decreases or when the fast slowly.When these situations arise, shows that the cooling water contains impurities, obstruct the normal flow of water, the best water switch will be removed at this time, let the cooling water flow directly from the body.If the water is still not smooth when I applied the wire a hard and long and thin steel items such as dredging, until the water clear.

When the cooling water stopped flowing, it is best to diesel generator set to turn a few laps, those remaining at this time, not easy flow of cooling water will flow due to the vibration of the diesel engine net, this can prevent water plugging is frozen falls, cylinder head oil cooling water flows into the shell in the future.Machinist also should pay attention to, if not remove the drain switch, etc. After the water, drain switch should be in an open position, to prevent those due to various reasons lead to the rest of the cooling water can't flow and corresponding freezing diesel engine parts cause unnecessary losses.

The radiator will be identified and repair leaks:

1 to block a radiator inlet and outlet from the overflow pipe or drain plug part of the installation of a joint, scored 0.15 to 0.3 KGF/cm2 of compressed air.The radiator to be included in the pool.If there is bubbled, is broken.

2 with the method of the water.Check, the radiator inlet and outlet of the congestion, since water mouth filled with water, observe whether the leak, find tiny cracks to facilitate, you can ask the radiator in a certain pressure or make a little vibration radiator, and then watch carefully and broken place there is water leakage.Welding radiator radiator welding trim usually adopt the method of soldering.Welds before welding place smeary rub-up, reoccupy scraper scrape new metal layer, and then proper heating, soldering iron after hot dip in zinc solution, then stick to solder.Glue the ponder, and weld again after washed with hot water around the welding of zinc oxide, to prevent corrosion.

3, the water chamber on welding repair, broken water chamber is not big, can directly use soldering repair, such as leakage is larger, with purple steel sheet welding repair.Welding stoppage time will be one side of the steel sheet and broken place first coated with a layer of solder, put steel sheet leaks, reoccupy heating iron on the outside, make the solder melts, the weld around.
