Abstract
The utility model provides a fracturing pump power end plunger sealing device, by seal receptacle 2, bearing 4, sealing washer 6, intercommunicating pore 7 etc. constitute, be fixed with seal receptacle 2 between clamping ring 5 and bearing 4, it has the recess to open on the interior disc of seal receptacle 2, the recess is embedded to have "K" style of calligraphy sealing washer 6, 2 axial equipartitions in seal receptacle have 3-6 intercommunicating pores 7 with the recess, owing to adopted "K" style of calligraphy sealing washer in the seal groove, therefore the problem of lubricating oil scurrying each other has been solved well, sealed effect improves greatly, has simple structure again simultaneously, characteristics such as simple to operate.
Description
The utility model relates to a kind of fracturing pump power end plunger sealing device in the petroleum machinery.
At present, the key equipment that the pressing crack construction operation is carried out in the oil field is a fracturing unit truck, and fracturing pump is the heart of fracturing unit truck, in case break down, pressing crack construction just can not carry out, sealing between fracturing pump power end and the plunger is again a key point, this seal failure will cause the plunger cooling liquid to be scurried in the power end lubricant oil, make deterioration of lubricant, thereby the bent axle axis tile takes place, the serious accident of crosshead adhesion guide plate, the sealing between fracturing pump power end and the plunger at present adopts " V " type packing to add bearing ring more, the sealing configuration of supporting ring, the major defect of this structure is: sealing effect is poor, particularly when malalignment is big slightly between crosshead and the plunger, when becoming to have in the plunger to-and-fro motion micro-radial displacement, sealing effect reduces greatly, very easily damages fracturing pump.
The purpose of this utility model is: the novel fracturing pump power end plunger sealing device that a kind of simple in structure, good sealing effect is provided.
The utility model is achieved in that by plunger 1, sealing seat 2, dividing plate 3, supporting base 4, pressure ring 5, seal ring 6, intercommunicating pore 7 to be formed, supporting base 4 and dividing plate 3 are by bolt, between pressure ring 5 and supporting base 4, be fixed with sealing seat 2, sealing seat 2 is a hollow circular cylinder, it is enclosed within on the plunger 1, have groove on the inner headed face of sealing seat 2, groove is embedded with " K " font seal ring 6, axially is evenly equipped with 3-6 intercommunicating pore 7 that communicates with groove at sealing seat 2.
Advantage of the present utility model is: owing in the seal groove of sealing seat, adopted " K " font seal ring, thereby solved the problem that lubricant oil is scurried mutually well, and sealing effect improves greatly, has characteristics such as simple in structure, easy for installation simultaneously again.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is described further:
The utility model is by plunger 1, sealing seat 2, dividing plate 3, supporting base 4, pressure ring 5, seal ring 6, intercommunicating pore 7 is formed, supporting base 4 and dividing plate 3 are by bolt, between pressure ring 5 and supporting base 4, be fixed with sealing seat 2, sealing seat 2 is a hollow circular cylinder, it is enclosed within on the plunger 1, one end of sealing seat 2 leans against on the supporting base 4, the other end is connected by the internal thread with supporting base 4 by pressure ring 5 and compresses sealing seat 2, sealing seat 2 is fixed in the annular space of pressure ring 5 and supporting base 4 formation, on the inner headed face of sealing seat 2, have groove, groove is embedded with " K " font seal ring 6, direction at sealing seat 2 edge axles is evenly equipped with 3-6 intercommunicating pore 7 that communicates with groove, the effect of intercommunicating pore 7 is to make groove and ambient pressure balance, guarantees the sealing effect of " K " font seal ring.
