In order to maintain a hydraulic breaker, inspection work is indispensable
First check whether the hydraulic oil is within the range of the normal scale line;
Then check whether the bolts, nuts and other parts of hydraulic hammer are loose. If they are loose, they should.Tighten with tools from time to time to prevent malfunctions. Pay attention that the inspection is carried out with the hydraulic breaker in a static state;
Then check the wear status ofhydraulic rock breaker parts. If the wear is serious, the parts should be replaced in time, otherwise there will be a bigger accident, which will seriously affect the service life of the hydraulic breaker.
Finally, measure whether the gap between the steel drill and the bushing exceeds 8mm (here 8mm is the maximum wear limit). If it has exceeded the maximum wear limit, the inner diameter of the steel rod bushing needs to be measured. If it exceeds, replace with a new steel rod liner. If it is not exceeded, you only need to replace the new steel rod.
After all the above inspections are completed, the hydraulic rock breaker can be prepared.
Butter is indispensable for smooth construction
The hydraulic breaker needs to be filled with butter every two hours of work.
After beating butter, we need to warm up
Many construction sites do not carry out the warm-up operation, just ignore this step and directly start the crushing. This is wrong. Before the crushing officially starts, observe the temperature of the hydraulic oil temperature monitor and keep the temperature at 40-60 degrees. , In colder areas, the warm-up time can be increased, and crushing can be carried out after warming up.
