Detailed Description
The present invention is further described in conjunction with the appended drawings so that the advantages and features of the present invention may be more readily understood by those skilled in the art and the scope of the invention will be more clearly defined.
As shown in figures 1, 2, 3 and 4,
the utility model provides a mud pump is with anticorrosive readily removable cylinder jacket seat, includes cylinder liner sleeve 1 and with 1 integrated into one piece's of cylinder liner sleeve ring flange 2, through-hole 3 unanimous with cylinder liner sleeve 1's internal diameter is seted up at the middle part of ring flange 2, and the chamfer has been seted up to through-hole 3 on the diapire of ring flange 2. The flange plate 2 is provided with a plurality of bolt holes 4 used for being connected with bolts in the circumferential direction, and the bolt holes 4 are uniformly distributed in the circumferential direction of the flange plate 2. During installation, bolts penetrate through the bolt holes 4 on the flange plate 2 to fixedly install the flange plate 2 on the outer wall of a piston cylinder connecting port of a high-pressure discharge cylinder at a hydraulic end of the slurry pump, and correspondingly, screw holes for screwing the bolts into are formed in the outer wall of the high-pressure discharge cylinder.
Two sealing washer mounting grooves 7 have been seted up on the outer fringe surface of ring flange 2, and wedge water drainage tank 8 has been seted up to the bottom lateral wall of ring flange 2, and the diapire of wedge water drainage tank 8 is for following the inclined plane that the ring flange lateral wall set up, the diapire diameter of wedge water drainage tank 8 reduces along the position department of sealing washer mounting groove to ring flange bottom gradually.
When the slurry pump is used, the flange plate 2 is fixedly arranged on the outer wall of a piston cylinder connecting port of a high-pressure discharge cylinder at a hydraulic end of a slurry pump by a bolt 9 penetrating through the bolt hole 4, the cylinder sleeve 10 is positioned in an inner hole of the cylinder sleeve 1, and the cylinder sleeve 10 and the cylinder sleeve are fixed by the cylinder sleeve gland 11.
In use, due to the reciprocating motion of the piston assembly 12 within the cylinder casing 10, the piston assembly 12 is a vulnerable component that is highly susceptible to wear and requires periodic replacement or replacement of the cylinder casing 10. Slurry or water inevitably leaks between the high-pressure discharge cylinder 13 and the liner sleeve 1 of the liner seat due to, for example, damage to the seal ring 14, and this leakage causes corrosion between the liner 10 and the liner sleeve 1 and makes it difficult to remove the liner. Therefore, by designing the drain hole 6, the drain hole 6 is positioned at the bottom of the cylinder sleeve 1 after the installation of the cylinder sleeve 1 is completed, so that water or slurry and the like leaked into the cylinder sleeve seat can be timely drained, and the situations of corrosion and difficulty in disassembly are avoided.
Meanwhile, slurry or water invasion is inevitable between the flange 2 and the high-pressure discharge cylinder 13 due to the use environment of the slurry pump, so that the flange 2 and the high-pressure discharge cylinder 13 are extremely easy to corrode and are difficult to disassemble. Therefore, two sealing ring mounting grooves 7 are formed in the surface of the outer edge of the flange plate 2, corrosion of slurry or water between the flange plate 2 and the cylinder wall can be avoided, and the two sealing ring mounting grooves 7 are located at the upper end and the lower end of the outer wall of the flange plate 2, so that the two sealing rings are mounted in the two sealing ring mounting grooves 7, corrosion can be effectively avoided in the place between the two sealing rings, and the cylinder sleeve seat can be detached more easily.
The invention improves the cylinder sleeve seat, and effectively solves the problem that slurry flows backwards to isolate the gap between the cylinder sleeve seat and the hydraulic cylinder rack 15 and cannot be rusted after the sealing ring 14 is damaged by installing the two sealing rings in the two sealing ring installation grooves 7. The drain hole 6 of position on the cylinder liner seat has been increased, has both had the effect of observation hole, and it can be timely discovery to have mud to spill here if sealing ring 14 breaks, has effectively stopped the mud refluence and has corroded the mud between cylinder liner seat, cylinder liner 10 and the cylinder liner gland 11, can not flow backwards the hookup location here, has effectively protected the cleanness of screw thread department, has had the quick detachable of wearing parts damage easily.
The above description is only exemplary of the present invention, and not intended to limit the present invention, and any modifications, equivalents, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
Other technical features than those described in the specification are known to those skilled in the art, and are not described in detail herein in order to highlight the novel features of the present invention.
