For hydraulic typeHammerIn other words, using too high or too low will interfere with the operating characteristics of the machine. The working pressure or total flow of the operating system is insufficient, the hydraulic drill rod is loose, the hydraulic seal is damaged, the pressure grease will pollute the environment, and the hydraulic pressure will be polluted. The breaker safety valve fails.
However, once the use is too high, the internal leakage of the hydraulic system will expand, and various characteristics of the hydraulic system will become unstable. The pressing operation of the breaker will slow down, reduce the quality rate, and increase the fuel consumption of the engine. The operating accuracy of the hydraulic system will decline. Control valve The spool and valve body are heated to expand, and the matching gap becomes smaller, which interferes with the movement of the spool, intensifies the damage, and even gets stuck, which interferes with the operation of the hydraulic system.
From then on, we need to test the relevant main parameters of the facility during the operation period of the normal use of the machine. Once abnormality is found, we will analyze the countermeasures that can be taken purposefully according to the main parameters.
Use the inspection basis to formulate the main parameters of the working pressure, and install an oil pressure gauge that exceeds the specified working pressure in the corresponding part, which can be divided into system working pressure and operating pressure measurement. For the oil circuit with a large shock, a shock-proof oil pressure gauge should be used. .The operation is realized by means of the pressure regulating valve and the relief valve. Before the test machine of the newly installed application system, the working pressure adjustment handle should be loosened, the oil pump should be turned on, and the adjustment handle should be slowly tightened. Observe the oil pressure gauge to adjust the working pressure to Standard value. The flow control adjustment is realized by the speed regulating valve or the throttle valve, and the total flow is generally adjusted according to the size of the orifice of the regulating valve core.
Use auxiliary instruments to check and use, immediately adjust and restore the operating characteristics of the machine, reduce the blockage of the operation process caused by the downtime, and help to adjust the operating cost.
