Abstract
It is related to a kind of packing_seal device of plunger pump, one end of packing box is connected on pump head body by clamping screw, the other end of packing box protrudes into pump head body, there is cavity in packing box, cavity is provided with packing, realizes the dynamic sealing to plungers pump plunger, has seal groove on the end face of packing box, edge face sealing member realizes static seal by edge face sealing member between packing box and pump head body in seal groove.The packing box and pump head body of the utility model are two individual parts, reduce manufacture pump head body waste of material, packing_seal part in packing box realizes the sealing of plungers pump plunger, and the edge face sealing member between packing box and pump head body realizes static seal, ensure that sealing effect.
Description
Technical field
The utility model belongs to oil drilling and extracting equipment field, is related specifically to plunger pump.
Background technique
Current routine, the development difficulty of unconventional petroleum resources are more and more big, are drilled the equipment scale of the operations such as well, pressure break
Constantly increase, pressure rating constantly increases.Therefore the sealing performance for improving plunger pump, reducing manufacturing cost becomes inevitable requirement.
Conventional plunger pump uses integrated sealing structure, i.e., the structure that is integrated of packing box and pump head body, packing etc. seal components peace
Inside pump head body, such design leads to the pump head body waste of material in manufacturing process.
Summary of the invention
The purpose of this utility model is that designing a kind of packing_seal device, it not only guarantees sealing performance, reduces simultaneously
Pump head body manufacturing cost.
To achieve the above object, the technical solution of the utility model are as follows:
A kind of packing_seal device, comprising: packing box, clamping screw, edge face sealing member, pump head body, packing, packing box
One end is connected on pump head body by clamping screw, and the other end of packing box protrudes into pump head body, there is cavity in packing box, empty
It is intracavitary that packing is housed, it realizes the dynamic sealing to plungers pump plunger, has seal groove on the end face of packing box, edge face sealing member is mounted in close
In sealing groove, static seal is realized by edge face sealing member between packing box and pump head body.
The good effect of the utility model are as follows: the sealing components such as packing are mounted in packing box, and packing box and pump head
Body is separately manufactured, therefore reduces the waste of pump head body blank material；And realize the dynamic sealing of plungers pump plunger；Meanwhile disk
The end face that root box is contacted with pump head body realizes the static seal between packing box and pump head body using end face seal structure, thus
It ensure that integral sealing.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the fluid end assembly part axis side view of Fig. 1.
Specific embodiment
Referring to Fig. 1-2, packing box 1 and pump head body 4 separate separately fabricated；One end of packing box 1 is extend into pump head body 4,
Sealing element packing 5 is mounted in the cavity 1-1 in packing box 1, realizes the dynamic sealing to plungers pump plunger；Packing box 1 simultaneously
The other end packing box 1 is fixedly connected with pump head body 4 with several clamping screws 2；There is seal groove 1-2 on the end face of packing box 1,
Using seal groove 1-2 and the edge face sealing member being mounted in slot 3 between packing box 1 and pump head body 4, static seal is realized, to protect
Demonstrate,prove the reliability of integral sealing.
