Background technique
In the oil field, the various operations in the petroleum technology flow processs such as drilling well, well workover all are to come the transportation work medium by slurry pump.
Present domestic oil field is widely used to be three cylinder single-acting piston type slurry pump and double cylinder double acting piston type slurry pump, and its deficiency is:
(1) power end lubricant oil is in pump case.Pump is when work, and abrasive dust and lubricant oil coexist, and has influenced the turbidity test and the lubrication effect of oil product;
(2) need subsidiary piston water to wash (cooling) system, the water rinse-system needs independently centrifugal pump water supply, and structure is loaded down with trivial details;
(3) the power end pattern is to slow down in the eccentric wheel combination, deceleration type structure heaviness in the eccentric wheel combination, and the movement inconvenience, the drive system power that needs is big, the operating cost height, maintenance, maintenance difficulties increase.
Summary of the invention
The purpose of this utility model is to upgrade on slurry pump is from the structure to the transmission at the existing various oil field of using, and releases working pressure height, big, the lightweight slurry pump of discharge capacity under the constant power condition.
The scheme that realizes above-mentioned purpose is: the dual-purpose mud pump with plunger of three cylinder horizontal borer well workovers, it has power end, fluid end, power end lubrication system, fluid end plunger pressure oil lubrication system.The base of pump is positioned at the bottom as fuel reserve tank simultaneously, the required lubricant oil of power end is all in fuel reserve tank, the gear oil pump intake is communicated with fuel reserve tank by oil outlet tube, the exhaust port of gear oil pump is delivered to each lubricating point of power end by oil exit pipe with the lubricant oil branch, and the return tube of collecting oil return is connected with fuel reserve tank.
Front end at oil outlet tube is equipped with oil purifier.
Described plunger forces oil lubrication system to have gear oil pump, the gear oil pump intake is communicated with fuel tank by fuel sucking pipe, the exhaust port of gear oil pump is delivered to each plunger lubricating point of fluid end by oil exit pipe with the lubricant oil branch, and the return tube of collecting oil return is connected with fuel tank.Front end at fuel sucking pipe is provided with oil purifier.
Plunger is forced oil lubrication system also to be provided with and is overflowed back oil pipe, remains in the suitable scope so that in time adjust the oil pressure of lubricating oil path.
The beneficial effects of the utility model are:
(1) designs independently power end lubrication system, improved the lubrication effect of each parts of power end.
(2) change piston water rinse-system into plunger pressure lubrication oil system, simple in structure; Plunger pressure lubrication mode, the wearing and tearing that alleviated plunger and filler prolong the working life of plunger combination.
(3) piston sealing structure is changed into the plunger seal structure, the easily damaged parts expense reduces greatly.
(4) deceleration system in the pump is changed in pump case side suspension speed reducer system, the weight of complete machine is alleviated greatly.
(5) multiple plunger quick detach rapid-changing structure makes things convenient for the user to regulate flow, pressure.
(6) bent axle five supporting meanss design, stress equalization, stable drive.

Embodiment
Accompanying drawing 1-5 has provided the utility model embodiment.
(1) main structure summary:
Power end mainly is made of frame 1, bent axle 2, crosshead 4, connecting rod 3, guide plate 5, gear reduction system 9, power end lubrication system 10 etc.; The base of pump promptly is a fuel reserve tank 14, and all in this fuel tank, the required lubricant oil of each parts of power end is delivered to each lubricating point, back backflow base by gear pump to the required lubricant oil of power end after pump-foot sucks.After oil purifier filters, suck by gear oil pump again, carry out next round and lubricate.The advantage of this system design is: abrasive dust that produces during pump work and heat bring in the base by lubricant oil, power end is used and more clean, and lubricant oil can be cooled off and filter fully simultaneously.Overcome the drawback that lubricant oil mixes coexistence in the pump power end in the past with abrasive dust.
Fluid end and existing plunger pump basically identical mainly are made of liquid cylinder 8, valve assembly 7, plunger combination 6, plunger lubrication system 12 etc.Fluid end adopts the pressure lubrication mode.
The base of the utility model pump is positioned at the bottom as fuel reserve tank 14 simultaneously, the required lubricant oil of power end is all in fuel reserve tank, the suction port of gear oil pump 17 is communicated with fuel reserve tank 14 by fuel sucking pipe 16, the exhaust port of gear oil pump 17 is delivered to each lubricating point of power end by oil exit pipe 18 with the lubricant oil branch, and the return tube 13 of collecting oil return is connected with fuel reserve tank 14.Front end at fuel sucking pipe 16 is equipped with oil purifier 15.
Described plunger forces oil lubrication system to have gear oil pump 21, the suction port of gear oil pump 21 is communicated with fuel tank 25 by fuel sucking pipe 20, the exhaust port of gear oil pump 21 is delivered to each plunger lubricating point of fluid end by oil exit pipe 22 with the lubricant oil branch, and the return tube 24 of collecting oil return is connected with fuel tank 25.Front end at fuel sucking pipe 20 is provided with oil purifier 19.Plunger is forced oil lubrication system also to be provided with and is overflowed back oil pipe 23, remains in the suitable scope so that in time adjust the oil pressure of lubricating oil path.
