Proper Use of Wrenches in Diesel Generator Maintenance

Compared with wrenches, everyone will be more familiar with them. They are an indispensable maintenance tool when we repair electromechanical equipment. For the maintenance of diesel generator sets, wrenches may be needed when necessary. But how to correctly use wrenches when maintaining generator sets, the editor of Dingbo Power Generator Manufacturer tells you.

1.Adjustable wrench handle. To adjust the torque arm, the length can be triggered according to the tightness of the adjusting screw to achieve different required force arms.

2.Universal joint head, because its head is movable, it can be used in various restricted parts.

3.Ratchet wrench handle can be used to speed up the disassembly or installation of screws to improve efficiency, but cannot reach the specified torque.

4.Torque wrench. Nuts and screws with specified torque. The head of the wrench can be matched with an appropriate socket according to the size of the nut. There is a dial at the tail to show the torque. Therefore, in the process of tightening the nut, the indication of the dial must be observed at any time according to the specified torque.

Because of their own several different structural characteristics, the above wrenches have different scopes, which depend on the specific situation of maintenance operations to choose correctly. In the process of use, the following points must be noted:

1.During use, the opening diameter of the wrench must match the size of the nut, and the contact between the two must be close. Do not be too loose or too tight, otherwise it is easy to cause "slipping" and "jamming" phenomena. Slipping is most likely to cause the opening of the wrench to crack, causing inconvenience in work. Therefore, when using an adjustable wrench, it must be within a good range, and strive to be able to determine the suitable wrench size when seeing the nut in work.

2.When tightening the screw, try to use hands first, and then use a wrench when the hand strength is not enough. As for how tight the screw should be, it is generally based on experience. Use a torque wrench to turn until the required torque stops, then apply a little more force to turn it quickly once to lock the nut.

3. The wrench should be kept clean. If it is contaminated by oil, it should be cleaned at any time. If necessary, the handle can be wrapped with cotton yarn to ensure safety. If the rusty screw is not easy to turn, you can inject an appropriate amount of diesel or kerosene, then tap it gently with a small hammer a few times, and the screw will loosen. Try not to use the method of splitting the nut to remove the nut, as this may cause other unexpected losses.
