Routine Maintenance Of Spiral Sand Washer

Spiral sand washer is widely used in highway, water and electricity, construction and other industries, and has high efficiency in washing, grading, impurity removal, and fine and coarse material washing. No matter how good the mechanical equipment is, it is necessary to do a good job in maintenance to ensure stable mechanical performance and make full use of its advantages. The same is true for the spiral sand washer. Maintenance is very important and needs to be done well by every user.

Because the working environment of the spiral sand washer is poor and dust is everywhere, it is necessary to pay attention to the cleaning work of the spiral sand washer during daily use, otherwise the production efficiency of the spiral sand washer will be affected. Also pay attention to the lubrication of the spiral sand washer. The spiral sand washer has two lubrication points, namely the gear reducer lubrication point and the lower bearing lubrication point. The gear reducer shall be lubricated with medium load industrial gear oil N68, N100 (GBN5903-86) or lubricating oil with similar performance. Replace the lubricating oil every six months; The lubricating point of the lower bearing is lubricated with ZG-3 calcium and grease, which can shorten or extend the lubricating oil, grease and service cycle according to the working environment and working conditions.

Large-scale equipment such as spiral sand washer needs manual operation. Therefore, in order to make its operation more professional and prevent unnecessary errors, special technical personnel should be responsible for taking care of it during its use. Operators must have certain skills. Before the installation of the sand washer, the operators must receive technical operation training to make them understand the principle and performance of the spiral sand washer and be familiar with the operating procedures. Remember, before starting the machine, make sure that the water tank is started with no load, and before stopping the machine, make sure that the sand in the water tank is cleaned. Overload operation is strictly prohibited.

In daily use, please pay attention to the noise of the spiral sand washer, observe the operation and working conditions of the spiral shaft, triangular belt, sealing device, water pipe and other components, check whether the motor and gearbox are overheated, and whether the bolts of each part are tightened, etc. After the spiral sand washer is operated for 3-6 months, the gearbox should be cleaned and replaced. The electrical equipment of large sand-washing equipment must have a reliable grounding device. In addition, the wires should be reliably insulated and installed in the coil. It is necessary to check the motor wiring for wear and leakage to avoid accidents. The seasonal maintenance of sand-washing equipment is also important, mainly replacing oil, fuel oil, antifreeze, and adding refrigeration facilities.

In addition, the spiral sand washer should be replaced with a new one in time after reaching its service life, because with the long-term use of the spiral sand washer, the aging degree will be higher and higher, and the failure rate will also increase, which not only affects the sand washing production efficiency, but also increases the maintenance cost.
