Description of drawings
Accompanying drawing 1 is looked the half section structural representation for the master of the utility model most preferred embodiment.
Accompanying drawing 2 is looked the half section structural representation for the master under the utility model most preferred embodiment use state.
Coding in the accompanying drawing is respectively: axle centered by 1, and 2 is left righting positioning sleeve, and 3 is right supporting positive cover, and 4 are the location pressure cap, and 5 is plunger, and 6 is plunger packing, and 7 is cylinder sleeve, and 8 is the plunger pull bar.
The specific embodiment
The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
In the utility model, for convenience of description, the description of the relative position relation of each parts all is that the Butut mode according to Figure of description 1 is described, as: the position relationship of upper and lower, left and right etc. is to determine according to the Butut direction of Figure of description 1.
Below in conjunction with embodiment and accompanying drawing the utility model is further described:
As shown in Figure 1, this pump plunger auxiliary installer comprises central shaft 1, left righting positioning sleeve 2 and right righting positioning sleeve; Left end at central shaft 1 has external screw thread, is installed with left righting positioning sleeve 2 at the middle part of central shaft 1, at the right part of central shaft 1 external screw thread is arranged, and the right part of central shaft 1 is installed with right righting positioning sleeve by screw thread.At first plunger 5 is fixedly mounted on the right part of central shaft 1 by left righting positioning sleeve 2 and right righting positioning sleeve, move by pulling central shaft 1, realize that central shaft 1 drives plunger 5 and enters in the cylinder sleeve 7, and be tightly fixed and link together with plunger packing 6 in the cylinder sleeve 7; Realize the installation between plunger packing 6 and the plunger 5; Whole process is easy for installation, and stability is high, and is safe.
Can according to actual needs, said pump plunger auxiliary installer be made further optimization and/or improvements:
As shown in Figure 1, right righting positioning sleeve comprises right supporting positive cover 3 and location pressure cap 4; Right part at central shaft 1 is set with right supporting positive cover 3, is installed with location pressure cap 4 by screw thread on the central shaft 1 on right supporting positive cover 3 right sides, and the external diameter of right supporting positive cover 3 is greater than location pressure cap 4.By changing the different right supporting positive cover 3 of external diameter, applicable to the plunger 5 of different model, location pressure cap 4 is threaded to realize the axial location to plunger 5 with central shaft 1; But economical with materials reduces waste like this, and is practical.
