How to prevent premature suction thread loosening

There is a strong connection between the suction connection of the suction dunk truck and the connection performance of the suction dunk truck. The working environment of the suction dunk truck is relatively poor, and it is usually discharged into the sewer. Mud or the relevant work for dung and dung, etc., so when the suction truck is designed, it is used to have relevant anti-loose measures, and the friction force used by the vehicle is loosened and preloaded. Anti-loose, spring washers are loose or have special self-locking threads and so on. The use of mechanical anti-loose method has a fuse to prevent loose, open pin anti-loose and so on.

The method of installing the spring washer of the suction truck is relatively simple and convenient, and the cost price thereof is also relatively low, and the use of the spring washer on the suction truck is also much more. It is the elastic deformation of the washer used, so that the thread pair is axially tensioned, and the beveled tip of the washer is also beneficial to prevent loosening. However, during the use of this gasket, all the elasticity was lost because of long-term compression and heat. Therefore, before the suction truck is fitted with spring washers, it should be checked whether the elasticity of the washers is intact. It can be seen that the gasket's interface and the two ends are not staggered to a certain angle. If there is no misalignment or the angle of misalignment is relatively small, it indicates that the gasket cannot be used. When selecting spring washers, their dimensions should be matched to the size of the bolts.

If the big connecting bolt of the engine connecting rod of the suction truck has loosened immediately, it will cause looseness of the connecting rod bearing, resulting in abnormal sound of the engine of the suction truck, and in case of seriousness, it will even damage it. Some related parts of the vehicle engine. When it is detected that there is a malfunction of the connecting rod bearing, it is seen that there are some other cotter pins that are connected to the screw-locking nuts that are connected. The cotter pin is already completely missing. This is because the cotter pin is too long because it is too high. In the operation, it will collide with the crank arm and it will break off. To determine the correct length of the cotter pin, the cotter pin should be inserted into the corresponding hole in the lock nut and tapped in place with a hand hammer. The length of the cotter pin should not exceed the length of the crank arm Plane, and finally in accordance with the desired requirements of the split pin on it.

Places that buy scrap metal will not buy wire if the insulation is still attached.


This is because they want to melt it down right away so it can be quickly sold.


The insulation gets in the way of this process and cannot be melted down along with the wire.


An automatic Scrap Wire Stripper can help you strip the insulation from the wire very quickly and easily.
