Operation method of hydraulic crusher

selection principle of hydraulic crusher

more and more users choose the supporting device of hydraulic crusher (hammer) when purchasing hydraulic excavator, so that the excavator can more effectively clean the floating stones and the soil in the rock gap when excavating the building foundation. The principle of selecting the hydraulic crusher is to select the most suitable hydraulic crusher according to the working stability of the excavator, the working pressure and power consumption of the hydraulic circuit of the working device. Before that, carefully read the operation manual of the hydraulic excavator, or conduct technical consultation with the excavator manufacturer and seller

correct use of hydraulic crusher

now take the domestic YC series hydraulic crusher as an example to illustrate the correct use of hydraulic crusher

1) read the operation manual of the hydraulic crusher carefully to prevent damage to the hydraulic crusher and excavator, and operate them effectively

2) before operation, check whether the bolts and connectors are loose and whether the hydraulic pipeline has leakage

3) do not use a hydraulic breaker to peck holes in hard rocks

4) do not operate the crusher when the piston rod of the hydraulic cylinder is fully extended or retracted

5) when the hydraulic hose vibrates violently, stop the crusher and check the pressure of the accumulator

6) prevent interference between the boom of the excavator and the bit of the crusher

7) do not immerse the crusher in water except the drill bit

8) do not use the crusher as a lifting appliance

9) do not operate the crusher on the track side of the excavator

10) when the hydraulic crusher is installed and connected with the hydraulic excavator or other engineering construction machinery, the working pressure and flow of the host hydraulic system must meet the technical parameter requirements of the hydraulic crusher. The "P" port of the hydraulic crusher is connected with the high-pressure oil circuit of the host, and the "O" port is connected with the oil return circuit of the host

11) the optimum hydraulic oil temperature of the hydraulic crusher during operation is ℃, and the maximum temperature shall not exceed 80 ℃. Otherwise, reduce the load of the hydraulic crusher

12 shock merchants operate cautiously. The shock test machine is based on the fact that the impacted sample is impacted by the hammer. According to the reporter, the signal generated by the high-speed load measuring sensor is amplified by the high-speed amplifier, which is quickly converted into a/d digital signal and sent to the computer for data processing. At the same time, it is sent to the computer for data processing by detecting the angular displacement signal. The accuracy is high On the basis of the impact structure conforming to the national standard, the instrument is equipped with a high-speed angular displacement monitoring system, a force detection sensor and an amplifier. After high-speed sampling and data processing by the computer, it can display N-t and J-T curves, save data, print data reports, etc.) The working medium used by the hydraulic crusher can usually be the same as the oil used by the hydraulic system of the main engine. Yb-n46 or yb-n68 anti-wear hydraulic oil is recommended for general areas, and yc-n41 is generally converted into negative difference 6 or yc-n68 low temperature hydraulic oil for cold areas. The filtering accuracy of hydraulic oil shall not be less than 50micro; m。

13) when the new and repaired hydraulic crusher is started, it must be recharged with nitrogen, and its pressure is 2.5, ± 0.5MPa

14) calcium base grease or compound calcium base grease must be used for lubrication between the shank of the drill rod and the guide sleeve of the cylinder block, and it shall be filled once per shift

15) when the hydraulic crusher works, the drill rod must be pressed on the rock first and a certain pressure must be maintained before starting the crusher hammer. It is not allowed to start in the suspended state

16) it is not allowed to use the hydraulic breaker as a crowbar to avoid breaking the drill rod

17) when in use, the hydraulic breaking hammer and the slender rod shall be perpendicular to the working face and shall not generate radial force

18) when the broken object has broken or begins to crack, the impact of the crusher shall be stopped immediately to avoid harmful "empty beating"

19) if the hydraulic crusher is to be stopped for a long time, it should discharge all nitrogen, seal the oil inlet and outlet, and store the cut iron under high temperature and -20 ℃
