How to deal with the high drilling and tapping pressure of energy radial drilling machine?
The normal operation of the radial drilling machine needs to be within a certain range of hydraulic pressure to operate normally. It can be seen that the normal pressure is the premise of the radial drilling machine. Therefore, the user should do a good job in adjusting the hydraulic pressure. In case of excessive pressure of the radial drilling machine, symptomatic analysis should be carried out and reasonable disposal measures should be taken.
The cause of the high pressure of the radial drilling machine system may be the failure of the pilot valve and the overflow valve. Under the action of the spring force, the main valve core is closed and cannot leak out, and the external load pressure increases, resulting in an increase in system pressure. In addition, the excessive wear of the seal of the relief valve and the main valve core will also cause the hydraulic system of the radial drilling machine to be unstable.
The pressure of the hydraulic system of the rocker drill is usually controlled by the hydraulic pump. When the pressure of the equipment is unstable, the problem of the hydraulic pump can be considered. If the hydraulic pump is a variable pump, there is a failure of the variable mechanism of the oil pump or the control spring of the overflow valve. If the above two situations are all right, you need to proceed to the next step.
Check whether the piston rod in the hydraulic cylinder of the rocker drill is connected with the connecting pin and the transmission wheel. The positioning of the transmission wheel needs to be realized by the cooperation of steel balls and circlips. Due to the complexity of the transmission mechanism, hydraulic components have high requirements for use and maintenance. In order to reduce maintenance time, when a transmission failure occurs, it is first necessary to Determine the location of the fault.
