Problems solved by technology

The disadvantage of the traditional sealed stuffing box is that the stuffing is hard filled in the stuffing box. When it is deformed by cold and heat, it is limited, and gaps are easy to appear between the stuffing, which affects the sealing effect.

Embodiment Construction

[0014] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] Such as figure 1 As shown, the water pump seal stuffing box structure of the mining sand washing machine in this embodiment includes a packing seat 2 and a packing 3 connected to the pump shaft 1, the packing seat 2 is connected to the packing ring 4, and the end of the packing seat 2 is connected to the pump shaft 1. The screw 8 is equipped with a packing gland 5, and the screw 8 is equipped with a compression spring 7 whose two ends are respectively against the packing seat 2 and the packing gland 5; the packing ring 4 has a deformation ring groove 6 arranged along its circumferential direction, and the packing 3 is arranged between the packing ring 4 and the packing gland 5 along the axial direction of the pump shaft 1.

[0016] The section of the deformation ring groove 6 is I-shaped, and the ring groove of the I-shaped structure...

Abstract

The invention relates to a water pump seal stuffing box structure of a mining sand washer. The water pump seal stuffing box structure comprises a stuffing base and stuffing which are connected to a pump shaft. A stuffing ring is connected in the stuffing base. A stuffing gland is arranged at the end portion of the stuffing base through screws. Compression springs with the two ends abutting against the stuffing base and the stuffing gland correspondingly are arranged on each screw. The stuffing ring is provided with a deformation ring groove arranged in the ring direction of the stuffing ring. The stuffing is arranged between the stuffing ring and the stuffing gland in the axial direction of the pump shaft. In the water pump seal stuffing box structure, through the joint action of the deformation ring groove of an I-shaped structure and the compression springs, generation of gaps during deformation of the stuffing in the cold and heat state is avoided, accordingly, the sealing performance of a stuffing box is prevented from being affected, and the work reliability of the stuffing box is improved.

Description

technical field [0001] The invention relates to the technical field of mining equipment, in particular to a pump body stuffing box of a sand washing machine. Background technique [0002] In the sand washing equipment, the water pump is an indispensable equipment, in which a sealing structure is required between the high-speed rotating pump shaft and the fixed pump body. This sealing mechanism is called a stuffing box, and its function is to reduce the pressure of the water when draining. It prevents air from entering the pump on the suction side, and plays the role of water lubricating and cooling the pump shaft. The disadvantage of the traditional sealed stuffing box is that the filler is hard filled in the stuffing box, and it is limited when it is deformed by cold and heat, and gaps are easy to appear between the fillers, which affects the sealing effect. Contents of the invention [0003] In view of the above shortcomings of the prior art, the applicant has conducted...
