Abstract
The utility model relates to a novel plunger slurry pump used for a drilling and workover machine in the oil field, which comprises a pump casing 3. A power end 1 and a hydraulic end 4 are respectively arranged at both ends of the pump casing 3; a forced lubricating box 2 is arranged at the bottom part of the power end; the gear reducing box 5 of the power end 1 is arranged on the outer side of the pump casing 3; the gear reducing box 5 is connected with the moving switching part of the power end through a gear reducing box and a pump casing connecting system 6; the moving switching part of the power end is connected with a fluid extruding device 8; the fluid extruding device 8 is connected with the pump valve of the hydraulic end. As the decelerating system of the power end is arranged outside the pump casing, the utility model has the advantages of light and handy appearance, great reduction of weight and reduction of product cost; as the piston sealing of the hydraulic end is changed into the plunger sealing, the utility model also has the advantages of static sealing, less attrition of the sealing element, long service life and low maintenance cost.
Description
Technical field
The utility model belongs to mechanical equipment technical field, particularly a kind of improvement of mud pump for petroleum drilling.
Background technique:
Slurry pump is as the imperative equipment of oil field drilling and repairing well, and is very big at the oil field consumption.Bore at present general oil field, well workover is arranged in the pump case with the power end deceleration system of slurry pump (structure as shown in Figure 3), need come the driven gear deceleration system with the eccentric wheel of a heaviness, cause the bulky of whole slurry pump product, weight increases, the product cost height.In addition, bore at present general oil field, well workover is adopted piston seal with fluid end of pump, and the shortcoming of this sealing means is the motion sealing, has directly caused quick abrasion, the life-span weak point of Sealing.
Summary of the invention:
The utility model purpose is the novel mud pump with plunger of design a kind of oil field drilling and repairing well, to overcome the defective of existing slurry pump.
Specifically, the novel mud pump with plunger of a kind of oil field drilling and repairing well, it has pump case (3), be respectively power end (1) and fluid end (4) at pump case (3) two ends, be pressure lubrication case (2) in the power end bottom, the gear reduction box (5) of power end (1) is arranged in pump case (3) outside, gear reduction box (5) partly is connected with the power end movement conversion with pump case connected system (6) by gear reduction box, power end movement conversion part is connected with liquid squeezing unit (8), and liquid squeezing unit (8) is connected with the pump valve of fluid end.
Described liquid squeezing unit (8) adopts the plunger combination seal.
The utility model beneficial effect is as follows:
1, oil field brill, well workover are arranged in outside the pump case with mud pump power end deceleration system.Advantage is that profile is light and handy, weight alleviates greatly, product cost lowers.
2, change the fluid end piston seal into plunger seal, the advantage of this sealing means is a standstill seal, and the wearing and tearing of Sealing are little, and the life-span is long, and maintenance expenses is low.

Fig. 3 is existing slurry pump schematic representation.
Embodiment
Accompanying drawing 1,2 has provided the utility model embodiment.
The novel mud pump with plunger of a kind of oil field drilling and repairing well, it has pump case 3, be respectively power end 1 and fluid end 4 at pump case 3 two ends, be pressure lubrication case 2 in the power end bottom, the gear reduction box 5 of power end 1 is arranged in pump case 3 outsides, gear reduction box 5 partly is connected with the power end movement conversion with pump case connected system 6 by gear reduction box, and power end movement conversion part is connected with liquid squeezing unit 8, and liquid squeezing unit 8 is connected with the pump valve of fluid end.Described liquid squeezing unit 8 adopts the plunger combination seal.
To be the rotation high-speed motion that will come from power source by power input shaft 7 will rotatablely move and be converted to straight reciprocating motion input liquid squeezing unit 8 by the gear reduction box back input power end movement conversion part of slowing down the utility model working principle, by this squeezing unit the liquid that the pump valve suction port sucks be discharged by its exhaust port.The movement conversion part can adopt general connecting rod.
The lubrication box 2 that relates in the utility model, gear reduction box 5, pump case connected system 6, power end movement conversion part, plunger combination, pump valve etc. are and well known to a person skilled in the art product, no longer describe its concrete structure here.
Claims (2)
1. novel mud pump with plunger of oil field drilling and repairing well, it has pump case (3), be respectively power end (1) and fluid end (4) at pump case (3) two ends, be pressure lubrication case (2) in the power end bottom, the gear reduction box (5) that it is characterized in that power end (1) is arranged in pump case (3) outside, gear reduction box (5) partly is connected with the power end movement conversion with pump case connected system (6) by gear reduction box, power end movement conversion part is connected with liquid squeezing unit (8), and liquid squeezing unit (8) is connected with the pump valve of fluid end.
