Convenient liquid mixing split plunger slurry pump

Abstract

The invention discloses a convenient liquid mixing split plunger slurry pump which comprises a hydraulic end and a power end. A plurality of liquid suction systems are arranged between the hydraulic end and the power end; each liquid suction system comprises a valve box assembly, a pull rod mounting cover and a transmission assembly; each valve box assembly is arranged at the hydraulic end, and each pull rod mounting cover is arranged at the power end; each transmission assembly comprises a pull rod, a pull rod sealing assembly, a plunger, a plunger sealing assembly, a plunger horizontal position fine adjustment assembly and a connecting rod; the plunger horizontal position fine adjustment assembly comprises a plunger end cover, two metal inner clamping rings and two elastic outer clampingrings; a liquid inlet of each valve box assembly is connected to a liquid inlet pipe; and a liquid outlet of each valve box assembly is connected to a liquid outlet pipe. The slurry pump can interchange single liquid, double liquids and multiple liquids, can mix liquid in different proportions, is stable in liquid suction pump pressure and is uniform to mix the liquids.

Description

technical field [0001] The invention relates to the technical field of pumps, in particular to a plunger 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. In this process, it is often necessary to inject mixed mud solutions with different ratios. The existing multi-cylinder mud pumps have a stroke of It is fixed and does not adapt to the actual situation of different usage environments and different requirements for mud solution and mixing. [0003] The plunger of the existing mud pump is made of meta...

AI Technical Summary

Problems solved by technology

The plunger, sealing ring, liquid inlet valve and liquid outlet valve of the mud pump work under the conditions of high temperature, high pressure and high speed. The uneven pressure in the pump will cause the service life of these devices to be very short, and most of these parts are Metal material, the surface is easily corroded and worn, and must be replaced regularly, otherwise it is easy to leak and partially fail, causing safety hazards

Therefore, the operation and maintenance costs of the above types of pumps are high. Although people have thought of many ways, they have not been able to fundamentally solve the problem.
