Description

Pressure maintaining cylinder tool clamp

Technical Field

The application relates to the technical field of pressure maintaining cylinder processing equipment, in particular to pressure maintaining cylinder tool pliers.

Background

A plurality of pressure-maintaining cylinders are arranged around the cone crusher, usually 4-6 pressure-maintaining cylinders are arranged, the phenomenon that the crusher is stuck is reduced through the design of the pressure-maintaining cylinders, and the service life of the crusher can be prolonged.

In the actual use process, the phenomenon of oil leakage of the pressure maintaining cylinder can often occur, the oil leakage phenomenon can greatly increase the use cost of equipment on one hand, and the pressure maintaining effect can be reduced to influence the normal work of the crusher in severe cases.

The reason for the above situation is found to be that in the production process, the installation of the sealing ring on the piston of the pressure maintaining cylinder is manually realized at present, and because the diameter of the inner ring of the sealing ring is smaller than the outer diameter of the piston, the sealing ring needs to be stretched and expanded when being installed, then is sleeved on the piston, and then is gradually pushed to the installation position.

The situation that the sealing ring after being installed is turned over and the like can occur, so that the sealing ring is not tight enough after the piston is installed, or the sealing ring is easy to wear and further the service life of the sealing ring is influenced, and therefore the leakage problem during use is caused.

The reliability of the installed sealing ring can only be guaranteed by the experience and the careful degree of an installer, the adjustment is time-consuming and labor-consuming under the condition of obvious roll-over, and partial roll-over condition is easy to be neglected when not obvious, especially for installers with insufficient experience. In addition, whether the inspection is careful or not and whether the inspection is carried out after the installation is difficult to supervise, so that the problem that the reliability of the installed sealing ring is low cannot be avoided even if the enterprise pays enough attention to the problem.
