The EH oil main pump skeleton oil seal TCM589332 is mainly equipped with the PVH series oil pump produced by VICKERS. When replacing the skeleton oil seal, pay attention to checking the inner wall for debris, scratches, dust, and casting sand. Special tools should be used to smoothly push the skeleton oil seal into the housing seat hole.
Working principle
The EH oil main pump skeleton oil seal TCM589332 of the anti-natural injection circulating pump mainly consists of an inner ring, an outer ring, a packing, and a skeleton. The inner and outer rings are filled with special packing, and the inner ring, outer ring, and packing form a sealed flow. During the working process of the cycle, the fire-resistant oil medium is pumped into the sealing cavity, and the filler blocks the medium between the inner and outer rings, forming a sealed state. At the same time, under the action of the skeleton between the inner and outer rings, the fire-resistant oil in the sealing courtyard will generate relative motion with the rotation of the recording shaft, forming a small lubricating oil film, further improving the sealing effect.
Overall, the keleton oil seal TCM589332 of the EH oil main pump is a device that uses the principle of friction sealing to achieve individual sealing. Its sealing effect and service life are influenced by the filler material and framework structure
