Engineering machinery seal design points:

1, Choose a reasonable sealing program, focusing on the following requirements.

First, consider that the dust-proof performance must be good. More than 80% of the failures of the hydraulic system are directly or indirectly derived from the stains in the system.

2, Choose the best seal

The seals of the same structure, the product quality of each company is very different. On the whole, the quality of foreign large seal parts company is relatively stable, but the probability of encountering fake goods is too great. Sometimes the so-called direct supply is not reliable. Most of the domestic seals are not very good, but at present some manufacturers' products have been catching up or even surpassing imported products, and the quality is stable and reliable, such as the tetrafluoroethylene and rubber seals produced by DMSSEALS.

3, Choose the right sealing material

There are many types of sealing materials, including a variety of metals, plastics and rubber. The same material, different company products have different performance. On the other hand, the same seal has different performances in different working conditions or different sealing schemes, so it must be carefully considered when selecting.

Note: Be sure to consider the seals under the premise of a reasonable sealing scheme, thenthe sealing material, and thenthe seal manufacturing company. If you don't have enough sealing experience, it's best to consider the seal company first, and let the seal company consider issues such as sealing solutions, such as DMS SEALS

Engineering machinery seal use points:

1. There must be a dust-free site during installation to prevent dust from being introduced into the system during installation.

2, Each mounting must be clean, iron filings, rust, paint, welding slag, etc.

3, To prevent dust from entering the tank mouth and other places (such as refueling).

4, Replace the filter element on time, the hydraulic system will produce stains during work, must be removed by replacing the filter.

5. The hydraulic oil will gradually deteriorate and oxidize during work, and the hydraulic oil must be replaced on time.

6. When replacing the oil pipe or other parts at the work site, pay special attention to dust and dirt.
