Abstract
The utility model discloses a three-cylinder single-action plunger pump, which is composed of a power device, a pump body, and a pump head, wherein, an eccentric wheel is arranged in a transmission tank of the pump body; the eccentric wheel drives a connecting rod which drives a plunger; the pump body is also provided with a sealing device which comprises the plunger, a positioning sliding sleeve, a rotation plug type oil cup, and an oil filtering ring; combined sealing rings which are formed by the overlapped arrangement of an elastic body and the sealing ring are arranged between the plunger and the positioning sliding sleeve; the oil filtering ring is arranged between the two combined sealing rings; the positions of the rotation plunger type oil cup and the oil filtering ring correspond to each other; the lower end of the oil filtering ring is provided with an oil leakage joint. The utility model has good sealing effect, and can be operated without failures for a long time.
Description
Technical field
The utility model relates to a kind of three cylinder single-action plunger piston pumps.
Background technique
Sometimes need to adopt chemical grouting in the dam foundation engineering construction, the perfusion medium is corrosive, and viscosity is higher, easily solidify, thus require the continuous time between failures of grouting pump long, and leakage must not be arranged when working.Existing grouting pump seal arrangement all can not adapt to requirement.
Summary of the invention
The purpose of this utility model overcomes the prior art shortcoming exactly, and a kind of three cylinder single-action plunger piston pumps are provided.
The purpose of this utility model is achieved in that a kind of three cylinder single-action plunger piston pumps, by power plant 1, the pump housing 2, pump head 12 is formed, setting-up eccentricity wheel 3 in the pump housing 2 transmission cases, eccentric wheel 3 drivening rods 4, connecting rod 4 drives plunger 5, the pump housing 2 also is provided with seal arrangement, seal arrangement comprises plunger 5, locating slide sleeve 6, cock-type lubricating cup 7, cross oil ring 8, plunger 5, be provided with between the locating slide sleeve 6 by elastomer 9 and the seal ring 10 stacked combined seal rings that form, cross oil ring 8 between two combined seal rings, cock-type lubricating cup 7 is corresponding with the position of crossing oil ring 8, crosses oil ring 8 lower ends and also is provided with leakage of oil joint 11.
Because adopt said structure, but the gap that the wearing and tearing of the elastomer 9 automatic compensation sealing parts of combined seal ring produce guarantees sealing effect, the abrasive dust that produces in the work overflows from the leakage of oil joint, prolongs plunger, seal ring life-span, no failure operation for a long time.
Description of drawings
Be described further below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of seal arrangement.
Fig. 1 double as Figure of abstract.
Embodiment
As shown in the figure, a kind of three cylinder single-action plunger piston pumps, by power plant 1, the pump housing 2, pump head 12 is formed, setting-up eccentricity wheel 3 in the pump housing 2 transmission cases, eccentric wheel 3 drivening rods 4, connecting rod 4 drives plunger 5, the pump housing 2 also is provided with seal arrangement, seal arrangement comprises plunger 5, locating slide sleeve 6, cock-type lubricating cup 7, cross oil ring 8, plunger 5, be provided with between the locating slide sleeve 6 by elastomer 9 and the seal ring 10 stacked combined seal rings that form, cross oil ring 8 between two combined seal rings, cock-type lubricating cup 7 is corresponding with the position of crossing oil ring 8, crosses oil ring 8 lower ends and also is provided with leakage of oil joint 11.
Work as sealing part abrasion, but the elastomer automatic compensation gap guarantees sealing effect, makes the long-time no failure operation of pump.In work, produce abrasive dust, overflow, prolong plunger, seal ring life-span from the leakage of oil joint.
