Abstract
The invention provides a sealing ring of a sand suction pump. The sealing ring comprises a sealing ring body made of a rubber material and an installation ring made of a metal material and provided with the annular cylindrical surface. The installation ring is arranged on the inner side of an inner ring opening of the sealing ring body, and the installation ring and the sealing ring body are integrally manufactured and formed. The outer cylindrical surface of the installation ring is covered with the inner ring opening of the sealing ring body. Furthermore, the height of the cylindrical surface of the installation ring is larger than or equal to the thickness of the inner ring opening of the sealing ring body in the length direction of a pump shaft. Furthermore, the metal material of the installation ring is preferably stainless steel or brass. The rubber sealing ring does not directly make contact with the pump shaft in the working process, and connection looseness or abrasion with the pump shaft caused by rubber aging is avoided; the situation that the rubber sealing ring body is deformed due to extrusion of an impeller and a water seal chamber pressing plate, then sealing is affected, and sand leakage is caused is avoided; abrasion of a water seal and a bearing is reduced, then the maintenance and use cost of the sand suction pump is reduced, the service life of the sand suction pump is prolonged, and the efficiency of the sand suction pump is improved.
Description
Technical field
The present invention relates to a kind of seal ring, especially relate to a kind of sand suction pump seal ring.
Background technique
The anti-bearing of existing sand suction pump enters the circular rubber seal that husky device uses, be socketed on the pump shaft of sand suction pump, between impeller and the water tight compartment pressing plate of ring, this structure and mounting type have following two defects: the first, at pump shaft in the radial direction, along with the wearing and tearing of rubber sealing ring and aging, its radial constrictive force be combined with pump shaft can be lost gradually, makes to occur space between pump shaft and rubber seal, causes into sand.The second, on the length direction of pump shaft, when pressure is excessive between seal ring and impeller, water tight compartment pressing plate, it can be made to be out of shape, to affect seal action; Pressure is too small or when not having pressure, its sealing effect can be made to reduce or lose, also can cause Lous sand.The sand that above two kinds of situations enter, all can accelerate the wearing and tearing of water seal and bearing, reduction of service life, increases maintenance load and the user cost of sand suction pump, has a strong impact on the utilization efficiency of sand suction pump.
Summary of the invention
technical problem:for the deficiency that above-described prior art exists, provide a kind of install reliable, prevent into husky sand suction pump seal ring.
technological scheme: sand suction pump seal ring provided by the invention, comprise the circular seal ring main body that rubber material is made, the outer ring mouth of seal ring main body is sealing lip, and its innovation is, it also comprises the installing ring of the cylinder annular that a metallic material is made; Described installing ring is arranged at the inner side of the inner ring mouth of seal ring main body, and integrally manufactured shaping with seal ring main body, and the inner ring mouth of seal ring main body is coated in the outer cylinder of installing ring.Like this, the seal ring main body of rubber material does not operationally directly contact with pump shaft, but realizes being connected with the installation of pump shaft by the installing ring being positioned at the rigidity inside its inner ring mouth, can not cause connect lax or wear and tear with pump shaft because of ageing of rubber, and then impact sealing, cause Lou husky.
For the distortion of the rubber seal main body that the extruding prevented because of impeller, water tight compartment pressing plate causes, the cylinder height of described installing ring can be made to be greater than or equal to the thickness of inner ring mouth on pump shaft length direction of seal ring main body.Like this, the squeeze force of impeller or water tight compartment pressing plate is also all born by the installing ring of rigidity, and seal ring main body other parts except the lip of its sealing lip of rubber, can not be subject to direct pressure, can not affect sealing effect because of distortion.
Preferably, the metallic material of described installing ring is stainless steel or brass.
beneficial effect: the technological scheme that present invention employs the rigidity installing ring that metallic material is made, the seal ring main body of rubber material does not operationally directly contact with pump shaft, but realize being connected with the installation of pump shaft by the installing ring being positioned at the rigidity inside its inner ring mouth, or can not cause Lou husky with the wearing and tearing of pump shaft because of the aging of rubber.When the thickness of the inner ring mouth that the cylinder height of installing ring is greater than or equal to seal ring main body on pump shaft length direction, the squeeze force of impeller or water tight compartment pressing plate is also all born by the installing ring of rigidity, the seal ring main body of rubber can not be subject to direct pressure except the lip of its sealing lip, can not affect sealing effect because of distortion.Due to the effect of above two kinds of aspects, present invention reduces the wearing and tearing of water seal and bearing, improve water seal and bearing working life, and then reduce the maintenance and use cost of sand suction pump, improve working life and the efficiency of sand suction pump.

Fig. 2: the radial cross-section of the embodiment of the present invention.
Have in figure: seal ring main body 1, installing ring 2.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is further illustrated.
Embodiment:
See Fig. 1, Fig. 2, in figure, seal ring main body 1, installing ring 2.
The sand suction pump seal ring of the present embodiment, comprise the circular seal ring main body 1 that rubber material is made, the outer ring mouth of seal ring main body 1 is the sealing lip of flare opening, also comprise the installing ring 2 being arranged at the cylinder annular inside seal ring main body 1 inner ring mouth that a stainless steel material is made, when the present invention uses, this installing ring 2 closely cooperates, with pump shaft synchronous axial system with pump shaft.This installing ring 2 is integrally manufactured shaping with seal ring main body 1, and the seal ring main body 1 inner ring mouth of rubber material is coated in the outer cylinder of this installing ring 2, and especially, the cylinder height of this installing ring 2 is greater than the thickness of inner ring mouth on pump shaft length direction of seal ring main body 1.
The protection domain of patent of the present invention is not limited to the concrete scheme of the present embodiment; every technological scheme utilizing metal installing ring provided by the invention; and carry out the production of sand suction pump seal ring, manufacture, assembling, usage behavior, within the protection domain all falling into this patent.
