Abstract
The utility model relates to a swashplate-type plunger pump. The swashplate-type plunger pump utilizes though framework oil seal mounting flanges. Framework oil seals are pushed into the flanges by big ends. The mounting positions of the framework oil seals in the flanges are confirmed by clamping rings, wherein the clamping rings are in the flanges. The framework oil seals of the pump can not be easily deformed and damaged. If the framework oil seals of the pump are damaged, and the framework oil seals need to be replaced. The framework oil seals are easily pushed out and are conveniently replaced by dismantling the clamping rings.
Description
Technical field
The utility model relates to a kind of swash plate plunger pump, relates in particular to domestic CY type plunger pump.
Background technique
Existing CY type plunger pump is used for flange plate (3) structure such as Fig. 2 of mounting framework oil sealing, and this structure is non-flow-through, and outside framework oil seal is installed as anti-upper the installation.The outside framework oil seal flange plate of this form is installed and is had following defective: when 1, outside framework oil seal pushes flange plate, because discontinuity easily causes the outside framework oil seal damage, thereby cause the leakage of pump.2, this structural framework oil sealing changes inconvenience.
Summary of the invention
The purpose of this utility model is to provide a kind of new CY type plunger pump, and this pump adopts flow-through (inner through hole) outside framework oil seal flange plate, thereby solves the above problem of background technique.
The technical solution of the utility model is achieved in that this pump adopts the outside framework oil seal mounting flange of flow-through, and outside framework oil seal pushes flange by large end, and the mounting point of outside framework oil seal in flange determined by the snap ring that is contained in the inside.
Due to the flange plate that adopts flow-through structure shown in Figure 4, the inner through hole that is installed as of outside framework oil seal is installed so, just is and installs, and outside framework oil seal is to use setting tool by large end face to push, and outside framework oil seal is stressed evenly, is difficult for deformed damaged.Push and carry out spacing with snap ring afterwards.In the time will changing outside framework oil seal, as long as split out snap ring, can release very easily outside framework oil seal, change.

Fig. 2 is existing outside framework oil seal mounting flange schematic diagram.Fig. 3 is existing outside framework oil seal mounting flange A-A generalized section.
Fig. 4 is outside framework oil seal mounting flange schematic diagram of the present utility model.Fig. 5 is outside framework oil seal mounting flange generalized section of the present utility model.
Number in the figure: 1, outside framework oil seal; 2, snap ring; 3, flange
Embodiment
A kind of improved plunger pump is characterized in that: this pump adopts the outside framework oil seal mounting flange 3 of flow-through; Outside framework oil seal 1 is used setting tool, pushes flange 3 by large end, and the mounting point of outside framework oil seal 1 in flange is definite by the snap ring 2 that is contained in the inside.Due to the flange plate that adopts flow-through structure shown in Fig. 3, the inner through hole that is installed as of outside framework oil seal is installed so, just is and installs, and outside framework oil seal is to use setting tool by large end face to push, and outside framework oil seal is stressed evenly, is difficult for deformed damaged.Push and carry out spacing with snap ring 2 afterwards.
