Description
Technical field
The invention belongs to the oil-well drilling equipment technical field, relate to a kind of method of the F of raising series slurry pump assembly quality of bolt of main bearing.
Background technique
Slurry pump is the important component part of drilling equipment, in the drilling process, and the washing solutions such as slurry conveyed or water in the boring.In direct circulation probing commonly used, slurry pump is with the earth's surface flushing medium--and Qing Shui ﹑ mud or polymer flush fluid are under certain pressure, by the bottom of high pressure hose, water tap and drill string center hole direct sending drill bit, be used for the cooling drill bit, and the earth's surface is removed and be transported to the landwaste that cuts.Slurry pump commonly used is piston type or plunger type, and by the crank up of power engine drive pump, bent axle drives piston again by crosshead or plunger moves reciprocatingly in pumping cylinder.Under the alternating action of suction and expulsion valve, realize force feed and the circulation of washing solution.
The F series slurry pump is a kind of new-type slurry pump, have simple in structure, volume is little, the life-span is long, the characteristics of smooth running, can satisfy the needs of middle-deep well operation.But the normally problem of dismounting of Main bearing bolt often appears in existing F series slurry pump when large assembling, its form of expression mainly contains two kinds: 1) Main bearing bolt can't normally cooperate with the tapped hole of frame main bearing seat, and the on-the-spot manual method of crossing button of screw tap that usually adopts solves the problem that occurs in this assembling; When situation is serious, even Main bearing bolt occurs and be sintered together and separate with main bearing seat, so that Erbium-doped is the situation of lucky Ignorant wantonly, and can only fall screw rod, built-up welding, the step such as bore hole and tapping thread mill drilling again again this moment by destroying bolt, boring, in order to make the Main bearing bolt normal mounting; 2) tapped hole of main bearing cap and frame main bearing seat can't centering, causes the Main bearing bolt can't normal mounting, and on-the-spot usually the employing redresses processing to main bearing cap on boring machine, so that the Main bearing bolt normal mounting.
Summary of the invention
The method that the purpose of this invention is to provide a kind of F of raising series slurry pump assembly quality of bolt of main bearing, can guarantee that Main bearing bolt and frame main bearing seat tapped hole are normal cooperates and the centering of main bearing cap and frame main bearing seat tapped hole, so that normally dismounting of Main bearing bolt.
The technical solution adopted in the present invention is, improves the method for F series slurry pump assembly quality of bolt of main bearing, and the method may further comprise the steps:
Step 1: process respectively by existing processing method and to obtain semi-finished product frame and semi-finished product main bearing cap, in the course of working of semi-finished product frame,
A. control the size conforms designing requirement of main bearing seat positioning spigot A on the semi-finished product frame, the lower side mark in position in this positioning spigot A is decided to be to reference for installation A, processing positioning datum using this reference for installation A as the base bearing screwed hole, process respectively two base bearing screwed holes of same main bearing hole both sides on this semi-finished product frame, guarantee that the distance between two base bearing screwed holes one of them and reference for installation A meets designing requirement, guarantee that the center line of these two base bearing screwed holes and the distance of mounting center line meet designing requirement
B. the main bearing tapped hole on the semi-finished product frame that machines among the step a is tested, obtains qualified semi-finished product frame,
C. whenever finish the processing of main bearing tapped hole on 10 semi-finished product frames, change screw tap, and tapping attachment is detected;
In the process of processing semi-finished product main bearing cap, one section on the semi-finished product main bearing cap among discontinuous two sections positioning spigot B as another benchmark, process two Main bearing bolt via holes, control these two Main bearing bolt via holes one of them center line and the distance between this another benchmark meet designing requirement, control simultaneously two centre distance between the Main bearing bolt via hole and meet designing requirement, the reference for installation B that to specify this another benchmark be the semi-finished product main bearing cap;
Step 2: the Main bearing bolt via hole on the semi-finished product main bearing cap that makes of the main bearing tapped hole on the semi-finished product frame that makes of cleanup step 1 and step 1 respectively;
Step 3: taking technique bolt, according to the service bolt adjacent with reference for installation B is installed first, rear installation is away from the order of the service bolt of reference for installation B, semi-finished product frame and semi-finished product main bearing cap after number of assembling steps 2 cleanings, and so that in the step 1 regulation the semi-finished product frame on reference for installation A and the reference for installation B on the semi-finished product main bearing cap coincide, obtain the semi-finished product pump housing of F series slurry pump, reference for installation B on the semi-finished product main bearing cap is the processing positioning datum, to the whole processing of this semi-finished product pump housing, make the pump housing;
Step 4: the service bolt on the pump housing that dismounting step 3 makes obtains frame and main bearing cap;
Step 5: the Main bearing bolt via hole on the main bearing cap that obtains of the main bearing tapped hole on the frame that obtains of cleanup step 4 and step 4 respectively;
Step 6: main bearing cap and frame and aforementioned all the other related components after the accurate Main bearing bolt of label taking, step 5 are cleared up respectively, obtain F series slurry pump semi-finished product according to existing assembly method assembling, in assembling process, so that the reference for installation A on the frame and the reference for installation B on the main bearing cap overlap, and by the Main bearing bolt of installing first away from reference for installation B, the order of the Main bearing bolt that rear installation is adjacent with reference for installation B is installed Main bearing bolt;
Step 7: remove the Main bearing bolt of installing in the step 6, adjust the main bearing play, then, remove front corresponding screw by each Main bearing bolt, and by the erection sequence in the step 6, the Main bearing bolt of pulling down is re-started installation, finish the assembling of F series slurry pump.
Method of the present invention is by strictly controlling the course of working of frame, main bearing cap, make the quality of product of these two kinds of parts obtain large increase, when effectively having avoided large assembling, since on the frame on Main bearing bolt hole, the main bearing cap screw thread cross hole location and the pitch-row error is excessive, cause on the frame problem that screw thread via hole on the Main bearing bolt hole and main bearing cap can't centering, effectively reducing Main bearing bolt can't dismounting phenomenon odds, has solved the problem that Main bearing bolt can't normally assemble.
