Description
(1) technical field: the utility model relates to a kind of boosting water injection pump mechanical seal device, is applicable to the boosting water injection pump of various models.
(2) background technique: the pressurized water injection Type of pump that use in domestic each oil field is a lot, have 3H-8/45 type, 3YPI-8/450 type, ZYT32Y-8/37 type, 3Z-8/450 type or the like.At present; mostly the sealing of water injection pump bent axle is to adopt rubber framework grease seal to seal; because boosting water injection pump all is at high pressure; long-term continuous operation under the condition of heavy load; temperature is higher in the pump housing, and oil sealing is easily aging under the high temperature, and each component wear of pump is accelerated; the bent axle gap increases; oil leak, each parts of pump can not guarantee that because of lubricated bad often shutdown water injection pump normally moves; need to drop into a large amount of manpowers; material resources are carried out irregular reparation and adjustment; adjust once, break-in face position change once, shorten once the working life of pump; so not only maintenance expenses is multiplied; and labor strength is big, inefficiency, also befouling environment.
(3) summary of the invention: easily aging in order to solve the boosting water injection pump oil sealing, oil leak, problems such as maintenance load is big, the purpose of this utility model provides a kind of " boosting water injection pump mechanical seal device ", replace oil sealing sealing with mechanical seal, good seal performance, energy-conservation, maintenance load is little, long service life.
The technical solution of the utility model realizes in the following manner:
The sealing device is by blind flange, elastic sleeve and retaining ring are formed, a seal groove is arranged in the interior step hole of blind flange, seal ring is housed in the groove, two protruding pins are arranged on the baffle plate of interior step hole, elastic sleeve is fitted on the protruding pin by two pits on the end face of the positioning ring outside, positioning ring is connected with the ripple reed pipe, the ripple reed pipe is connected with dead turn, one deck hard alloy face is arranged on the outside end face of dead turn, this alloy face tightly rides over the hard alloy face of retaining ring, a seal groove is also arranged in the endoporus of retaining ring, seal ring is housed in the groove, positioning screw hole is arranged on the retaining ring.
The beneficial effects of the utility model are:
1, this product hermeticity can be good, when axle rotates, because the elastic reaction of ripple reed pipe is close together the hard alloy face of elastic sleeve friction circle and the hard alloy face of retaining ring all the time, plays seal action.
2, this product good energy-conserving effect, because it is to lean on the cooperation of two hard alloy faces to realize sealing, because surface of contact is little, and also smooth, reduced frictional resistance, reduced motor load relatively.
3, this product is owing to good seal, and crank lubricating can not leak, and has created a good environment for oil field water filling work.
4, this product simple installation, long service life.
(4) description of drawings:
Fig. 1 is a general structure schematic representation of the present utility model
Fig. 2 is an elastic sleeve schematic representation of the present utility model
Fig. 3 is that K of the present utility model is to view
(5) embodiment: the utility model is elaborated below in conjunction with accompanying drawing
Provided concrete structure of the present utility model among Fig. 1,2,3, this device mainly is made up of blind flange 1, elastic sleeve 4 and retaining ring 12.
A seal groove 2 is arranged in the interior step hole 5 of blind flange 1, " O " type rubber seal 3 is housed in the groove, two protruding pins 6 that are symmetrically distributed along circumference are arranged on the termination baffle plate 7 of interior step hole 5, fastening screw 19 is arranged on the blind flange;
Elastic sleeve 4 constitutes one by positioning ring 18, ripple reed pipe 8 and friction circle 10, two pits 9 that are symmetrically distributed along circumference are arranged on the outside end face of positioning ring, positioning ring is connected with ripple reed pipe 8, the ripple reed pipe is connected with friction circle 10, and the extremely hard smooth again hard alloy face 11 of one deck is arranged on the outside end face of friction circle;
A seal groove 15 is arranged in the endoporus of retaining ring 12, " O " type rubber seal 14 is housed in the groove, three uniform positioning screw holes 13 are arranged on the retaining ring, the extremely hard smooth again hard alloy face 11 of one deck is also arranged on the outside end face of retaining ring;
During assembling, earlier retaining ring 12 is contained in the place, location of running shaft 17, and it is fastening by positioning screwn 16, " O " type rubber seal 14 in the retaining ring is pressed on the axle 17 just, again elastic sleeve 4 is sleeved on the axle 17,11 in the hard alloy face of friction circle 10 tightly rides on the hard alloy face of retaining ring 12 on the elastic sleeve, the positioning ring 18 of elastic sleeve is contained in the step hole 5 of blind flange 1, two pits 9 on positioning ring 18 outside end faces, just be fitted on two protruding pins 6 on the blind flange baffle plate 7, the external diameter of positioning ring is squeezed on interior " O " type rubber seal 3 of blind flange just, by clamping bolt blind flange 1 is tightened at pump output axle head again.
During water injection pump work, because pump shaft rotates, make the hard alloy face of elastic sleeve friction circle and the hard alloy face of retaining ring, under the elastic reaction of ripple reed pipe, tightly ride over together all the time, play seal action, lubricant oil can not leak.
