Abstract
The utility model discloses a mechanical seal device for a gear oil pump shaft head, comprising a press cap, a mechanical seal seat, a spring seal ring seat, a spring, a mechanical seal ring and a seal loop. The outer wall of the spring seal ring seat is provided with an annular seal slot; the lower end surface of the spring seal seat is provided with a flute around a shaft hole; an 'O' shaped seal slot is arranged on the outer wall of the shaft hole of the lower end of the spring seal seat; the upper end surface of the mechanical seal ring is provided with a fixed pin; the bottom surface of the flute is provided with a fixed pin hole; the spring seal seat configured with the spring and the lower end surface of the mechanical seal ring pressing on the end of the spring and the upper end surface of the mechanical seal seat are hermetically matched. The mechanical seal device for a gear oil pump shaft head has the advantages of simple structure, and good sealing performance, and the material of the seal element is easily obtained.
Description
Technical field
The utility model relates to a kind of seal arrangement, belongs to a kind of mechanical seal device that uses the gear oil pump spindle nose in the burning machine that oil acts as a fuel.
Background technique
The structure of the mechanical seal device of the gear oil pump spindle nose in the external at present burning machine equipment of introducing is complicated, and the material of sealed member is had relatively high expectations.The gear oil pump that production domesticization is produced is at the mechanical seal device of spindle nose and since the material of sealed member can't solve, there is poor sealing performance in the spindle nose seal arrangement of the gear oil pump that production domesticization is produced, does not reach the problem of seal request.
Summary of the invention
The purpose of this utility model provides a kind of mechanical seal device of gear oil pump spindle nose of simple in structure, good seal performance.
The purpose of this utility model is achieved in that it is to comprise gland, mechanical sealing base, spring sealed ring support, spring, mechanical seal ring, seal ring; The outer wall of described spring sealed ring support is established annular seal groove, and groove is established around axis hole in spring sealed seat lower end surface, and the axis hole outer wall of spring sealed seat lower end is established " O " shape seal groove, and fixing pin is established in the mechanical seal ring upper-end surface, and groove floor is established the fixing pin hole; The spring sealed seat of configuration spring and be pressed in the lower end surface of mechanical seal ring of spring end and the upper-end surface of mechanical sealing base is sealed and matched.
Mechanical sealing base described in the utility model is installed on a last as a whole structure, and select copper product for use, has the high advantage of wear resistance, spring in the spring sealed ring support is that downward masterpiece is used on the seal ring, the lower end surface of seal ring and the upper-end surface of mechanical sealing base are sealed and matched, also play the effect of automatic compensation end wear.The utlity model has material simple in structure, sealed member and solve the advantage of good seal performance easily.
