Embodiment 1

[0037] Example 1. Such as Figure 1 to Figure 10 As shown, a wear-resistant and pressure-stabilized plunger mud pump includes a transmission assembly, a plunger assembly, a sealing lubrication assembly and a valve box assembly. The port 12 and the liquid outlet 13, the inner chamber 19 arranged in the box, the right mounting hole 113 of the plunger arranged on the left side wall of the box body 11, the right mounting hole 113 of the plunger is set with a center axis transversely arranged The plunger right mounting sleeve 14, the right end of the plunger assembly is located in the inner cavity 19 of the tank, the tank 11 is provided with a liquid inlet valve 15, a liquid outlet valve 16, the liquid inlet valve 15 is connected with the liquid inlet 12, and the liquid outlet valve 16 It is connected with the liquid outlet 13.

[0038] The plunger assembly includes a plunger wear-resistant jacket 21 arranged transversely to the central axis, a plunger inner shaft 22 arranged lat...

Embodiment 2

[0053] Example 2. Such as Figure 11-13 As shown, the difference between this embodiment and Embodiment 1 is that a sediment filter 410 is provided on the pipeline 49 between the oil outlet 48 and the oil-water separator 46 .

[0054] The mud pump includes a pressure relief assembly. The pressure relief assembly includes a pressure relief hole 61 on the side wall of the box body 11 that can communicate with the inside and outside of the box body 11 . The pressure relief hole 61 is provided with a valve 62 . There are multiple pressure relief devices, which can quickly release pressure and facilitate the internal maintenance of valve box components. Through the pressure relief hole, the residual mud inside the valve box assembly can also be released, which is convenient for cleaning the inside of the valve box, and the medium can also be cleaned when the mud pump is not in use, so as to avoid oxidation and freezing in winter.

Abstract

The invention discloses a wear-resisting pressure-stabilizing plunger slush pump. The wear-resisting pressure-stabilizing plunger slush pump comprises a transmission assembly, a plunger assembly, a sealing ad lubricating assembly and a valve box assembly. The valve box assembly comprises a box, a liquid inlet, a liquid outlet and a plunger right mounting hole. The plunger right mounting hole is connected with a plunger right mounting sleeve, and a liquid inlet valve and a liquid outlet valve are arranged in the box. The liquid inlet valve is connected with the liquid inlet, and the liquid outlet valve is connected with the liquid outlet. The plunger assembly comprises a plunger wear-resisting outer sleeve with the center axis arranged transversely, a plunger inner shaft with the center axis arranged transversely, and an inner sealing assembly. The transmission assembly comprises a transmission assembly supporting box, a transmission device, a plunger left mounting hole and a plunger left mounting sleeve. The sealing and lubricating assembly comprises a metal sealing sleeve, a non-metal fiber sealing part and a lubricating assembly. The wear-resisting pressure-stabilizing plunger slush pump can solve the problems that a slush pump plunger in the prior art is large in machining difficulty, high in manufacturing price, inconvenient to replace, unstable in pumping pressure and thelike.

Description

technical field [0001] The invention relates to the technical field of pumps, in particular to a mud pump. Background technique [0002] Mud pump is a very important production equipment in the oil field industry and an important part of drilling equipment. It is mainly used for deep well and shallow well operations in oil fields. It can complete water blocking and oil displacement operations to oil wells, and can also be used for cement plugging during oil field workover. , channel sealing, well washing, sand washing and cementing operations, near and long-distance transportation of crude oil and pressure testing, etc. [0003] The plunger of the existing mud pump is made of metal materials. Because the plunger needs to move repeatedly and bear a certain high pressure, the plunger often adopts an integrated structure. Although this structure has good rigidity, pressure resistance and impact resistance, but During manufacture, the precision of the thread on the surface and ...
