Breaking hammer pressure relief, also known as leakage, is one of the common problems of breaking hammers. Once the breaking hammer finds pressure relief, it will not be able to create system pressure, and it will also cause air pollution, increase the downtime of the breaking hammer, and reduce production efficiency. , increase production costs, affect production and cause unpredictable serious harm, therefore, control the leakage of the breaker. However, there are several situations for pressure relief. The leakage of the breaker is mainly divided into leakage at the fixed seal and movement seal. Leakage. So why is there a pressure release? Let's find out together:
1. Install elements.
When installing the breaker, avoid rough operation. If too much force will cause the parts to deform, the parts should be carefully and carefully before installation. During installation, the parts should be dipped in a little hydraulic oil and pressed gently. It is rubber components such as sealing rings, dustproof rings, O-rings, etc. If they are cleaned with gasoline, they will easily age, lose their original elasticity, and reduce the sealing performance.
2. Part damage.
The seal is made of oil-resistant rubber and other materials. Long-term use will cause aging, cracks, and damage, which will cause system leakage. If the parts are damaged by collision during work, the seal will be scratched, which will cause leakage.
3. Selection of seals.
The reliability of the breaker mainly depends on the design of the seal and the selection of the seal. Because the sealing structure in the design is not scientific, the use of the seal does not meet the specifications, and the compatibility of the hydraulic oil and the sealing material is not considered in the design. Load conditions, ultimate pressure, working speed, ambient temperature changes, etc., will more or less directly and indirectly lead to leakage of the hydraulic system. In addition, because the use scene of the breaker has dust and impurities, it is necessary to choose Appropriate dust-proof seal to prevent dust and other waste from entering the system to pollute the oil, damage the seal, and cause leakage.
