Abstract
The utility model discloses a novel piston of a high-pressure grouting pump, wherein an annular support plate is sleeved at the end part of the piston rod of the piston; annular blue pelts and polyurethane are sequentially sleeved against the support plate; the blue pelts and the polyurethane form a piston ring; a press plate is pressed outside the blue pelts; a lock nut preventing the press plate from loosening is screwed on the screw rod outside the press plate; and a pin preventing the lock nut from loosening is inserted onto the lock nut. The annular blue pelts and the polyurethane forming the piston ring have V-shaped cross sections. As the piston ring consists of two layers of blue pelts and one layer of polyurethane, the piston has the characteristics of corrosion prevention, abrasion resistance and high-temperature resistance, expands after absorbing water, has excellent sealing property, and can scrape off dust from the cylinder wall during the moving process; and the combination of the hard blue pelt and the soft polyurethane improves the sealing property of the piston and greatly prolongs the service life of the piston.
Description
One, technical field
The utility model relates to a kind of parts of conveying equipment, specifically a kind of novel high-pressure grouting pump piston.
Two, background technique
The slush that the material that high-pressure injection pump is carried is made up of sand, stone, cement and water requires the piston of piston type grouting pump should have wear-resisting, withstand voltage intensity and hardness, has excellent sealing property softness again, and is also corrosion-resistant.If intensity and hardness are not enough, will soon be between cylinder body and working surface of piston by wearing and tearing or crowded bad such as sand, stones; If do not have certain softness, sealing is poor, and water will be missed in the slush in the course of conveying, can't guarantee to carry quality; Corrosion-resistant degree deficiency also is easy to make piston to damage, and influences its working life.Current, the piston of the piston type high-pressure injection pump of application, its structure is set with the nitrile rubber folder cloth piston ring of ring-type for the piston rod outer rim; Use this kind structure and material, its intensity and hardness are not enough, and softness also can not get usage requirement; And corrosion-resistant; Piston ring scuffing is serious, and easy deformation comes off, and working life is short.
Three, summary of the invention
In order to solve the deficiency of existing technology, the purpose of the utility model provides a kind of good seal performance, the novel high-pressure grouting pump piston of long service life.
The technological scheme that realizes the purpose employing of the utility model is: this piston mainly is made up of piston rod, supporting plate, piston ring, pressing plate and locknut; The end of piston rod is with the ring-type supporting plate; Be with the blue skin of ring-type, polyurethane successively near supporting plate, blue skin and polyurethane are formed piston ring, and blue skin is pressed with pressing plate outward; Be screwed with the locknut that prevents that pressing plate is loosening on the piston rod outside the pressing plate, be inserted with the bearing pin that prevents that locknut is loosening on the locknut.
The transverse section of the blue skin of the ring-type of described composition piston ring, polyurethane is a V-type.
The beneficial effect of the utility model is: because piston ring is made up of two-layer blue skin, one deck polyurethane, and characteristics such as blue leatherware has certain rigidity, and is anticorrosion, wear-resisting, high temperature resistant, the expansion of suction back, good seal performance; The polyurethane softness is wear-resisting, corrosion-resistant, has good sealing, can wipe the dust on the casing wall off in moving; Both soft or hards combine, and have improved the sealing of piston, have prolonged the working life of piston greatly.
Four, description of drawings
Fig. 1 is the sectional structure chart of the utility model high-pressure slip-casting pump piston.
Five, embodiment
In the accompanying drawings, the utility model high-pressure slip-casting pump piston mainly is made up of piston rod, supporting plate, piston ring, pressing plate and locknut; The end of piston rod 1 is with ring-type supporting plate 2; Be with the blue skin 4 of ring-type, polyurethane 5 successively near supporting plate 2, blue skin 4 is formed piston ring 3 with polyurethane 5, the blue skin 4 outer pressing plates 6 that are pressed with; Be screwed with the locknut 7 that prevents that pressing plate is loosening on the piston rod outside the pressing plate 6, be inserted with the bearing pin 8 that prevents that locknut is loosening on the locknut 7.The transverse section of the blue skin 4 of the ring-type of described composition piston ring 3, polyurethane 5 is a V-type.Described blue skin is treated hard ox-hide.
Claims (2)
