Description
Technical Field
The invention relates to the field of petroleum engineering equipment, in particular to a drilling pump base precision and installation adjusting structure.
Background
The current situation of the drilling pump design and manufacture industry is that users promise that key moving parts at the power end of the drilling pump are freely maintained for 1 year, the key moving parts of the drilling pump comprise a power input gear, a crankshaft bearing, a connecting rod bearing, a crosshead, a slideway and the like, and the hydraulic end wearing parts of the drilling pump comprise a cylinder sleeve, a piston, a valve body, a valve seat, a sealing part and the like, have short service life and are one of the main running costs of the users. In order to promote the development of the drilling pump industry, the existing drilling pump design and manufacturing enterprises actively provide a challenging target, promise that key moving parts at the power end of the drilling pump are free for 10 years, prolong the service life of wearing parts at the hydraulic end of the drilling pump by more than 3 times, and provide a necessary precision requirement for a drilling pump base by one of guarantee measures in order to meet the ambitious target.
The drilling pump industry is not deeply researched due to the very low quality commitment time of users, particularly, the research on a base is a very weak link, the base is considered to bear the weight of the drilling pump, so the design and manufacturing precision requirement of the base is very low, the base of the drilling pump is researched by the invention that the base is arranged between a frame of the drilling pump and concrete, the upper surface of the base is connected with the frame through bolts, the lower surface of the base is contacted with the concrete, and the base has the following functions besides bearing the weight of the drilling pump:
function 1, the original design manufacturing accuracy of frame can not be destroyed after the upper surface of base and frame bottom surface are connected with the bolt. All moving parts such as a power end input shaft, a crankshaft, a connecting rod, a crosshead and the like and key valve box parts at a hydraulic end are arranged on a drilling pump frame, the size of the drilling pump frame is very large, taking a 2400hp drilling pump frame as an example, the length of a hole for installing the crankshaft is more than 2000mm, the lengths of a hole for installing a slideway and a valve box are more than 2700mm, in order to realize free 10-year-package maintenance of the key moving parts at the power end of the drilling pump for a user, the precision of the frame must meet the overall requirements, for example, the verticality requirements of an axis for installing the crankshaft hole and an axis for installing the slideway hole on the frame are 4-grade precision (0.05 mm), the planeness requirement of the bottom surface of the frame is 6-grade (0.06 mm), the surface roughness is Ra6.3 mu m, while the verticality requirements of the axis of the crankshaft hole and the axis for installing the slideway hole on the frame are between 6-grade and 7-grade (0.127 mm) for free 1-year-package maintenance of the key moving parts at the power end of the drilling pump for the user, the flatness of the bottom surface of the rack has no requirement at all, only needs to be processed, meets the requirement of surface roughness Ra25 μm, has different commitment time for users, has quality which is not a grade at all, and can not damage the precision of the rack after the upper surface of the base is connected with the bottom surface of the rack by bolts. The design of the base to satisfy function 1 in the first place therefore requires a corresponding precision.
And 2, the contact area between the base and the concrete is large, and the vibration of the drilling pump during operation is reduced. The drilling pump moving part belongs to a crank-link mechanism, the first-order inertia moment, the second-order inertia moment and the rotating inertia moment of the crank-link mechanism cannot be balanced in the drilling pump and are necessarily transmitted to the outside of the drilling pump, and the first-order inertia force, the second-order inertia force and the rotating inertia force of some drilling pumps can even be transmitted to the outside of the drilling pump to cause the vibration of the drilling pump. The base meeting the function 2 can be guaranteed to be installed in a manufacturing enterprise, but the drilling pump is used in a field, the field for installing the drilling pump is temporarily built in different places, and the surface of the field cannot be as good as the surface of the field for installing the drilling pump in the manufacturing enterprise, so that how the base with high precision guarantees that the precision in the manufacturing enterprise is continuously maintained after the base is installed on the temporarily built surface of the field in the drilling enterprise is very important work.
Therefore, the problem to be solved urgently is formed by researching the precision and the installation and adjustment structure of the base of the drilling pump.
