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 manufacture 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 adopt a series of guarantee measures to meet the ambitious target, for example, strict requirements on the precision of a frame and a base of key basic parts, and the suction pipe support is a structure related to the precision maintenance of the frame and the base.
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, and has quality which is not a grade at all, so that the precision of the rack cannot be damaged after the upper plane of the base is connected with the bottom surface of the rack by bolts, and the precision of the base is matched with that of the rack, thereby meeting the requirement of no deformation of the rack.
The hydraulic end of the drilling pump is provided with a suction pipe, the suction pipe is connected with a valve box at the hydraulic end, the valve box is arranged on a machine frame, the machine frame is arranged on a base, the suction pipe is separated from the base, if the suction pipe is not fixed with the base, the rigidity of the whole pump set in operation is influenced, and therefore the suction pipe and the base are required to be fixed together. At present, a drilling pump which promises that key moving parts at a power end of the drilling pump are freely maintained for 1 year is a drilling pump which measures the distance between a suction pipe and a base after the drilling pump is assembled, a support frame is assembled and welded on an assembly site, the support frame of the suction pipe and the base are welded together, welding stress cannot be eliminated after welding, the deformation of the base is caused, and the base and a rack are fixed together, so that the rack can also deform. Therefore, the drilling pump which promises free maintenance of key moving parts at the power end of the drilling pump for 10 years is not provided with a connecting structure of a welding suction pipe.
The drilling pump which is promised by a user to maintain key moving parts at the power end of the drilling pump for free 10-year bags also requires high interchangeability of parts, the support seats which are welded and assembled cannot be interchanged, and the original support frames which are welded and assembled must be cut off and welded again when a new suction pipe needs to be replaced. Therefore, the research on the suction pipe supporting structure of the drilling pump, which can not be welded on the assembly site and can well ensure that the suction pipe is fixed with the frame, constitutes an urgent need to solve the problem.
