Utility model content
The purpose of this utility model is to provide a kind of new-type fracturing pump spring supports, use monoblock cast, structure letter
It is single, it is easily worked, the spring support of opposite traditional type is not easy long-pending sand, and does not destroy the internal structure of pump head body.
To achieve the above object, the utility model uses following technical scheme：
A kind of new-type fracturing pump spring support, overall structure is L-shaped, including traversing section and vertical section；The traversing section
Arc transition is set with the junction of vertical section, to reduce stress concentration；The both ends of the traversing section are taper surface and are filling
It is close to the pump head body intracavitary conical surface when with state；The middle part of the traversing section to having a spring positioning platform, spring positioning platform it is straight
Diameter is less than the diameter of bore of pressure break pump hydraulic end conical compression spring, and spring positioning platform is inserted into pressure break pump liquid when to assemble
In the endoporus of power end toper compressed spring；The top of the vertical section is equipped with mounting hole, one end of mounting hole direction sucking gland
Mounting hole accurate positioning and smoothly coordinate with sucking gland protrusion cylinder table equipped with chamfering, when to assemble.
Said program can also advanced optimize for：
The bevel angle of the taper surface is 20 ° -40 °.
The bevel angle of the taper surface is 30 °.
The material of the spring support uses stainless steel.
The utility model has the advantages that：
1. simple in structure, dependable performance, easy to use；
2. processing capacity is small, processing cost is low, high in machining efficiency；
Rapid, precision is assembled 3. realizing, is conducive to improve working efficiency and work quality；
4. not easily causing pump head body product sand, be conducive to the normal operation of fracturing pump；
5. not destroying the internal structure of pump head body, it is conducive to extend pump head body life time；
6. being subjected to the test of field application, good resultant effect is shown.
