Abstract
The utility model discloses a combined plunger piston, belonging to a plunger piston, in particular to a combined plunger piston. The utility model is characterized in that a working face bush is arranged on the outer surface of a plunger piston body. The utility model has the advantages that the plunger piston is designed into two parts as a reusable plunger piston body and a replaceable working face bush; at the same time the plunger piston body volume is reduced, which realizes repeated utilization of resources, saves great amount of metal materials and reduces equipment operation cost.
Description
Affiliated technical field
The utility model belongs to plunger, particularly a kind of combined type plunger.
Background technique
Plunger is the critical piece of plunger pump, in use, the working surface of plunger is pulled out groove owing to friction or by filler, to such an extent as to bad efficient reduction will occur sealing scraps, particularly plunger is used costly material mostly, cost an arm and a leg, some patent proposes the technological scheme of combined type plunger, a kind of combined type plunger is disclosed as CN87201292, form by plunger rod and plug, the Sealing that is characterised in that of the present utility model is located between plunger rod and the plug, and successively plug, Sealing and plunger rod is connected by Flexible Connector.This patent is unsuitable for plunger pump and uses.
Summary of the invention
The purpose of this utility model provides a kind of technological scheme that is suitable for the novel combination type plunger of plunger pump application.
The technical solution of the utility model is that a kind of combined type plunger is characterized in that: the plunger body appearance is equipped with the working surface sleeve.
Described plunger body outer surface intermediate portion except that the fitting surface of two ends reservation 1-15cm is an annular recess.
The working surface sleeve is installed in the plunger body appearance in the mode of interference fit in the utility model, the working surface sleeve can be pulled down replacing as the wearing and tearing of working surface generation in use, only having avoided, the working surface wearing and tearing can reduce user cost with regard to needing to change the phenomenon of whole plunger.Plunger body appearance intermediate portion except that the working surface of two ends is an annular recess, and the economical with materials that promptly can reduce cost alleviates plunger weight again, is convenient to install.
The beneficial effects of the utility model are that plunger design is become reusable plunger body and removable working surface sleeve two-part, reduced the volume of plunger body simultaneously, realize the recycling of resource, can save a large amount of metallic material, reduced the equipment operation cost.
