The utility model provides a kind of anti-stab leakage device of the short pump of high-pressure plunger and the short pump of high-pressure plunger anti-pricked, overcomes
The deficiency of the above-mentioned prior art can effectively solve when plunger pump packing seal failure in cementing operation, cementing slurry thorn leakage
The problem of will be directed into plunger pump grease-box and leading to deterioration of lubricant.
The technical solution of the utility model first is that being realized by following measures: a kind of short pump anti-pricked of high-pressure plunger
Device, including end cap, oil sealing and supporting positive cover, the step-like through-hole for having the wide right part of left part narrow in the middle part of end cap, the outside of supporting positive cover
In narrow step-like of the wide right part of left part, the left part diameter of supporting positive cover is greater than the left part diameter of through-hole, and the right part of supporting positive cover is sleeved on
In the through-hole of end cap right part, the oil sealing left part of supporting positive cover withstood on stepped hole is set in the end cap of supporting positive cover left part.
Here is the further optimization and/or improvements to above-mentioned utility model technical solution:
Above-mentioned supporting positive cover is nylon supporting positive cover.
Above-mentioned end cap is equipped at least two bolt mounting holes.
Handle is fixed on the outside of above-mentioned end cap.
The technical solution of the utility model second is that being realized by following measures: a kind of high-pressure plunger anti-pricked is short
Pump, including the anti-stab leakage device of the short pump of high-pressure plunger, the short pump of cementing concrete truck high-pressure plunger and plunger, in cementing concrete truck high-pressure column
It fills in and is set in short pump and can be fixedly mounted on cementing concrete along the plunger that the short pump of cementing concrete truck high-pressure plunger moves left and right, end cap
The side of the short pump of overall height hydraulic plunger, oil sealing and supporting positive cover are sleeved on plunger.
The utility model reasonable and compact in structure, it is easy to use, it can not only be effectively reduced when plunger pump packing_seal fails
Cause cementing slurry thorn leakage to be directly entered the hidden danger of plunger pump grease-box, and the processing is simple, it is at low cost, easy to operate,
Highly-safe, maintenance is simply.
Detailed description of the invention
Attached drawing 1 is schematic diagram of main cross-sectional structure of the utility model embodiment 1.
Attached drawing 2 is schematic diagram of main cross-sectional structure of the utility model embodiment 2.
Coding in attached drawing is respectively as follows: 1 for end cap, and 2 be oil sealing, and 3 be supporting positive cover, and 4 be bolt mounting holes, and 5 be handle, and 6
It is plunger for the short pump of cementing concrete truck high-pressure plunger, 7.
Specific embodiment
The utility model is not limited by following embodiments, can technical solution according to the present utility model and actual conditions
Determine specific embodiment.
In the present invention, for ease of description, the description of the relative positional relationship of each component is according to specification
The Butut mode of attached drawing 1 is described, such as: the positional relationship of upper and lower, left and right is the Butut according to Figure of description 1
Direction determines.
The utility model is further described below with reference to examples and drawings:
Embodiment 1: as shown in Fig. 1, the anti-stab leakage device of the short pump of the high-pressure plunger includes end cap 1, oil sealing 2 and supporting positive cover 3,
The step-like through-hole that the middle part of end cap 1 has the wide right part of left part narrow, the outside of supporting positive cover 3 are helped in narrow step-like of the wide right part of left part
The left part diameter of positive set 3 is greater than the left part diameter of through-hole, and the right part of supporting positive cover 3 is sleeved in the through-hole of 1 right part of end cap, in righting
Cover the oil sealing 2 for being set with and withstanding on the left part of supporting positive cover 3 on stepped hole in the end cap 1 of 3 left parts.
Can according to actual needs, the anti-stab leakage device of pump short to above-mentioned high-pressure plunger makes further optimization and/or improvements:
As shown in Fig. 1, as needed, supporting positive cover 3 is nylon supporting positive cover.
As shown in Fig. 1, for the ease of installation and removal, end cap 1 is equipped at least two bolt mounting holes 4.
As shown in Fig. 1, for the ease of positioning, handle 5 is fixed on the outside of end cap 1.
Embodiment 2: as shown in Fig. 2, a kind of short pump of high-pressure plunger anti-pricked, including the short anti-stab neglected loading of pump of high-pressure plunger
