Hydraulic Breaker is a lot of engineering machinery ancillary equipment, now many of the projects is also more and more demand for modern machinery and equipment, broken hammer suitable oil pressure is needed to work, a lot of friends all know this thing, but how much is the oil pressure ?

According to the design pressure parameters, an oil zhi pressure gauge larger than the design pressure is installed at the corresponding position. For new excavators and crushing hammers, it is generally between 200-220, while for old excavators, it is generally above 230.

If oil pressure is too great in the process of the actual use is likely to be broken hammer load will be bigger, then the oil temperature increase, the oil temperature is too high, can make the transmission of the hydraulic oil pressure is insufficient, which can lead to equipment can't work normally, if long time not to solve it might damage the broken hammer accumulator, cause air leakage, oil spill. Once we find that the oil temperature rises too high during use, we should consider replacing the oil cooler of the equipment or installing auxiliary cooler to achieve our purpose. So,Timely cleaning of the oil filter is also crucial.

The main reasons for the decrease of hammer frequency are insufficient pressure or flow in the hydraulic system, loose brazing rod, wear of hydraulic seal, pollution of hydraulic grease and failure of safety valve, etc.

Solution: Check the hydraulic fracturing hammer oil pump, adjust the oil pressure and flow rate to be too high or too low, so as to realize the control of hammer head; Check the oil path of the hydraulic crushing hammer to avoid the blockage of the pipeline, which affects the impact frequency of the hydraulic crushing hammer; Replace worn parts.
