Hammer, The key is to deal with some hard rocks, which are highly risky and difficult. During long-term construction operations, apart from the breakage of the breaker, some failures will inevitably occur. The long construction period delays the workload, which is what each of our operators will eventually Existing difficulties. How can we increase the service life of the breaker? Reduce the occurrence of common failures?
First, inspection is the most important thing. Before the failure occurs, the early detection of signs can quickly deal with small failures and reduce the occurrence of major failures. The abnormality of the breaker hammer during the work of many excavators is ultimately due to the small abnormality of the breaker Did not check out, for example, whether the high and low pressure oil pipes of the breaker have loosened? Is there any oil leakage in some pipelines?
2. Maintenance, the daily maintenance of the breaker is often mentioned in our previous articles. Next, we will talk about two more.
1. Make butter regularly and reasonably to avoid excessive damage to consumable parts. The correct way to fill butter is to insert the drill rod vertically on the ground and press it to the bottom, otherwise the butter will enter the striking chamber and be brought to the cylinder by the piston to mix with hydraulic oil. , will cause "black oil". Fill the grease into the guide sleeve and the inner liner, and try to avoid the grease from adhering to the piston.
2. Replace the hydraulic oil in 2000 hours, and replace the hydraulic oil return filter in 500 hours. (If the working environment is harsh and the dust is large, the replacement time needs to be advanced.)
3. Storage. When the breaking hammer is cut off from the excavator for storage, in order to avoid the entry of rainwater, the side of the rear cylinder body needs to be raised, and it should be stored in a room with a low temperature. Close the hydraulic system with a plug to prevent foreign matter from entering the hydraulic system. For long-term storage, nitrogen gas should be released. At the same time, pay attention to the rust prevention of the piston, release the nitrogen gas of the rear cylinder, push the piston to the inside with the ejector rod, and apply anti-rust at the end Oil.
The high working intensity of the breaker will undoubtedly have a certain impact on the service life, but if the application and maintenance are in place, the probability of common failures will also be reduced. The details are well done, which is convenient and worry-free and saves money!
