By adopting the design, the plunger and the sealing component sleeved on the plunger can be disassembled and replaced without disassembling the whole pump body through the end cover and the plunger which are coaxially arranged; simultaneously, through setting up the sealing washer of different hardness, material, can play the suggestion effect in seal assembly local failure, and then be convenient for observe, maintain and maintain.
Drawings
Fig. 1 is a schematic structural view of a high-pressure slurry pump according to the present embodiment.
Detailed Description
The invention is further illustrated by the following specific examples.
As shown in FIG. 1, the high-pressure slurry pump convenient for maintenance comprises a shell 1, a one-way valve assembly 2, a plunger 3, a sealing assembly 4 and an end cover 5; the casing 1 is hollow and is provided with openings at the upper part and the bottom part respectively, a one-way valve component 2 is arranged at an outlet at the upper part of the casing 1 and serves as a pulp outlet 6, a plunger 3 and an end cover 5 are arranged at the openings at the two sides of the bottom part of the casing 1 respectively, wherein the one-way valve component 2 is also arranged in the opening at the end cover 5, a pulp sucking opening 7 is arranged at the side of the one-way valve component 2, and a sealing component 4 is sleeved on the plunger 3; thus, the flow control of the slurry in the shell 1 is realized through the matching of the plunger 3 with the one-way valve assembly 2 at two positions of the slurry outlet 6 and the slurry suction port 7.
In the high-pressure slurry pump convenient to maintain, the axial lead of the plunger 3 and the axial lead of the end cover 5 are coaxially arranged, so that the plunger 3 can penetrate through the shell 1 and can move out of the end cover 5; the plunger 3 is of a nested structure, that is, the plunger 3 comprises an outer sleeve 31 and a core rod 32, and the outer sleeve 31 and the core rod 32 are connected through an end bolt 33.
In the high-pressure slurry pump convenient to maintain, the sealing assembly 4 comprises a cylindrical base frame 41, and an elastic sealing ring 42 and a hard sealing ring 43 which are respectively sleeved on the base frame 41, and when the sealing assembly 4 is sleeved on the plunger 3, the plunger 3 and the inside of the shell 1 are sealed through the elastic sealing ring 42 and the hard sealing ring 43.
In the high pressure mud pump for easy maintenance, the base frame 41 further includes an oil reservoir 44 for storing the injected oil through the oil reservoir 44 of the seal assembly 4 when the seal assembly 4 is mounted on the plunger 3.
By adopting the design, the plunger and the sealing assembly sleeved on the plunger can be disassembled and replaced under the condition of not disassembling the whole pump body through the end cover and the plunger which are coaxially arranged; meanwhile, the sealing rings with different hardness and materials can play a role in prompting when the sealing assembly is locally failed, and observation, maintenance and repair are facilitated.
