Description
Technical field
This utility model belongs to high-pressure pump technical field, especially relates to the fluid end structure of a kind of high-pressure pump.
Background technology
The fluid end structure of existing double plunger high-pressure pump is usually and is made up of two plungers, plunger bushing, cylinder body and casing, and it also requires the hitch structure such as the swash plate supporting with it or bent axle drives, thus make complicated integral structure, so that the efficiency of assembling of complete machine is low, it is therefore necessary to improved.
Summary of the invention
The purpose of this utility model is the deficiency existed for above-mentioned prior art, it is provided that the fluid end structure of a kind of high-pressure pump, and it has efficiency of assembling height, saves the feature of cost and long service life.
To achieve these goals, this utility model be the technical scheme is that the fluid end structure of a kind of high-pressure pump, including plunger assembly, left plunger bushing, right plunger bushing, cylinder body and casing,
Described plunger assembly includes left connecting rod and right connecting rod, described left connecting rod and the dismountable connection of right connecting rod, the inner side of described left connecting rod is provided with left plunger, the inner side of described right connecting rod is provided with the right plunger relative with left plunger coaxial line, the external peripheral surface of described left plunger and right plunger is coated with wear-resistant coating, and the arranged outside of described right connecting rod has union joint;
Described left plunger bushing, right plunger bushing and cylinder body are provided with connecting rod by groove, described cylinder body is additionally provided with the check valve of water inlet, outlet, pressure relief opening and the corresponding left plunger of difference and right plunger;
Described left plunger bushing is connected with the side of cylinder body, the opposite side of described cylinder body is connected with right plunger bushing, described left connecting rod is arranged on the connecting rod on left plunger bushing, cylinder body and right plunger bushing by groove, and make that left plunger is supporting with left plunger bushing to be connected, described right connecting rod is connected with left link detachable, and making that right plunger is supporting with right plunger bushing to be connected, the periphery of the combinative structure of described plunger assembly, left plunger bushing, right plunger bushing and cylinder body is provided with casing.
The coalition of described left connecting rod and right connecting rod is rectangular shape.
After adopting said structure, this utility model is compared to the prior art advantageously: left plunger of the present utility model and right plunger connect into a double plunger assembly by left connecting rod and right connecting rod, only need union joint to be connected with eccentric hitch structure and just can drive left plunger and the acting of right plunger, without using swash plate or crankshaft structure to do traction drive, facilitate the overall assembling of high-pressure pump, the efficiency of assembling making high-pressure pump is greatly improved, simultaneously also because eliminating swash plate or bent axle hitch structure, the cost of complete machine is made to reduce;The wear-resistant coating of the external peripheral surface coating of left plunger and right plunger makes increase service life of the present utility model.
