What are the interference of air pressure on the breaker

　　HammerIt is an auxiliary equipment in many construction machinery and equipment. At present, many projects have more and more requirements for contemporary machinery and equipment. The breaker must be suitable for its own steam pressure to work normally. I think many people understand this, but steam How much pressure should be appropriate, and what are the disturbances of steam pressure to the breaker?

The steam pressure test is based on the main parameters of the design pressure, and the oil pressure gauge that exceeds the design pressure is modified in the corresponding part. For the new excavator with a breaker, it is generally 200-220, and for the old excavator, it is generally 230 above.

If the steam pressure is too high in a specific application, it is very likely that the load on the breaker will increase, and as the temperature will rise, if the temperature is too high, the transmission pressure of the hydraulic oil will be insufficient. This will cause the machinery and equipment to fail to work properly. If it is not handled for a long time, the breaker accumulator will be damaged, causing steam leakage and oil leakage. In our case, once we find that the temperature rises too high, we should Taking into account the replacement of the oil channel cooler of the mobile phone, or the assembly of an auxiliary cooler to achieve their effect, it is very important to clear the oil channel filter immediately.

The main reasons for the decrease of the breaker frequency are insufficient pressure or flow of the steam pressure system, loose brazing rod, wear of hydraulic seals, pollution of hydraulic grease, failure of safety valve, etc. Solution: Check the hydraulic breaker oil pump, adjust the steam pressure and flow rate. High or too low to complete the control of the hammer head; check the oil passage of the hydraulic breaker to prevent the pipeline from being blocked and interfere with the impact frequency of the hydraulic breaker; replace the worn parts.
