Abstract
The utility model discloses a five-cylinder piston pump which solves the problem that a lubrication pipeline of an existing five-cylinder piston pump utilizes the fact that a box is arranged outside. The five-cylinder piston pump comprises a box, a crank shaft main shaft bearing, a crosshead lateral pin bearing, a crosshead guide plate, a disassembling port, a connecting rod bearing shell, a connection rod, a crosshead, an intermediate rod and a lateral pin, wherein the connecting rod bearing shell is connected with the crosshead, the crosshead lateral pin bearing is arranged inside the crosshead which is connected with the intermediate rod, the lateral pin is arranged inside the crosshead lateral pin bearing, and the crank shaft main shaft bearing and the crosshead guide plate are arranged inside the box. The five-cylinder piston pump brings great convenience to installation, maintenance and construction work, reduces the number of connection pipelines, saves installation space on a table top, reduces cost, and is economical and practical.
Description
Technical field
The utility model relates to a kind of five cylinder pumps, is the Five-cylinder piston pump of a kind of large discharge capacity, high pressure.
Background technique
Five-cylinder piston pump is used for the fracturing unit truck that the oilfield fracturing work is used.
Dismounting mouth on the existing Five-cylinder piston pump casing is in side vertical surface or the casing top levels of casing, causes the inconvenient integral demounting of connecting rod, connecting rod bearing shell, crosshead, Jie's bar and lateral pin; Crank spindle bearing, cross guide plate, crosshead lateral pin bearing, lubricated pipeline adopt casing to arrange outward, and pipeline is many, random, and operator's operation inconvenience with it pump is easily trampled on lubricated pipeline when causing construction; Platform is provided with the Special lubricating fuel tank, causes on the platform space narrow.
The model utility content
The purpose of this utility model provides a kind of Five-cylinder piston pump, the outer problem of arranging of lubricated pipeline employing casing that exists to solve existing Five-cylinder piston pump.
Technical solutions of the utility model are as follows: a kind of Five-cylinder piston pump, comprise casing, crank spindle bearing, crosshead lateral pin bearing, cross guide plate, dismounting mouth, connecting rod bearing shell, connecting rod, crosshead, Jie's bar, lateral pin, described connecting rod bearing shell links to each other with crosshead by connecting rod, be provided with crosshead lateral pin bearing in the described crosshead, described crosshead links to each other with Jie's bar, described lateral pin is located in the crosshead lateral pin bearing, and described crank spindle bearing, cross guide plate are located in the described casing.
As further improvement of the utility model, described dismounting mouth is obliquely installed described casing (9) top, and the included angle A of the end face of described dismounting mouth and described casing is 135 ° of-150 ° of angles.
The utility model is compared with existing Five-cylinder piston pump and is had following characteristics:
1. crank spindle bearing, cross guide plate, crosshead lateral pin bearing, lubricated pipeline adopt in the casing and arrange.
2. the dismounting mouth is obliquely installed, and can make connecting rod, connecting rod bearing shell, crosshead, Jie's bar and lateral pin make things convenient for integral demounting or installation.
3. box height is increased, bottom half removes the peripheral hardware lubricating oil tank as lubricant sump, has reduced the pipeline connection, has saved the installing space of preciousness on the table top.
Three characteristics of the present utility model for I﹠M, construction operation provide a great convenience, have reduced connecting line, have saved the installing space on the table top, have reduced cost, and are economical and practical.
Below in conjunction with accompanying drawing the utility model is described further.
