Abstract
The utility model discloses a split type high pressure plunger pump which is easily detached. The aim of the utility model is to provide a plunger pump which has the advantages of simple structure and convenient maintenance and assembling-disassembling. The essential point of the technical scheme is that the plunger pump comprises a pump seat, a high pressure cylinder and a plunger rod, wherein, the pump seat is inserting-connected with the high pressure cylinder. A sealing ring is provided at the contact surface between the pump seat and the high pressure cylinder. The split type high pressure plunger pump of the utility model is used for the high pressure water cutter.
Description
Technical field
The utility model relates to a kind of plunger pump, refers in particular to the split type high-pressure plunger pump a kind of easy to assemble that is used for the high pressure water cutting device.
Background technique
Water jet cutting machine (high-pressure water cutting machine) is to be pressurized to 200MPa～380MPa by the water that essence is filtered, form a kind of jet of about tripler speed again through jewel nozzles, can change its pressure into concentrated kinetic energy, thereby reach the purpose of energy cutting material; The water jet cutting machine is realized cutting process to material because of the high-energy jet beam of its nonthermal source, it is fast to have cutting speed, the precision height, otch is smooth, no dust, no thermal distortion, pollution-free, reduce characteristics such as waste of material, being particularly suitable for cutting various method for hot cutting is difficult to competent or can not material processed, in aviation, military project, glass, stone material, building, decoration waits in the fine finishing enterprise and has obtained extensive use, is used for titanium alloy, copper coin, steel plate, aluminium sheet, cast iron, granite, marble, ceramic tile, glass, chemical fibre, timber, cloth, paper, leather, the cutting of plastic or other material.
Core component in the water jet cutting machine is an extremely-high tension generator, extremely-high tension generator is to promote high-pressure plunger pump compression water body by mechanical force or hydraulic coupling to produce ultrahigh pressure, traditional hydraulic coupling promotes extremely-high tension generator, be that the hydraulic coupling promotion plunger that utilizes hydraulic station to produce moves the compression water body, can produce the water pressure of about 200MPa～380MPa, but complex structure, cost height, use and maintenance cost height; And mechanical force promotes extremely-high tension generator, is to utilize motor directly to drive the crankcase drive plunger to move the compression water body, can produce the water pressure of about 200MPa～380MPa, structure is simple relatively, cost is low, and use and maintenance cost is also lower, thereby social recoverable amount is also bigger.The high-pressure plunger pump that uses in the mechanical type extremely-high tension generator, its pump seat and high-pressure cylinder are overall structures, and the Sealing in the high-pressure cylinder belongs to easily damaged parts and working life certain restriction is arranged, and often needs frequent replacing, this brings inconvenience to use; Simultaneously the guide sleeve of plunger is arranged in the high-pressure cylinder usually, because guide sleeve need bear ultrahigh pressure, and particularly when hydraulic pressure surpasses 250MPa, as easy as rolling off a log damage, only be the time about a week its working life, causes the increase of operating cost.
The model utility content
The technical problems to be solved in the utility model provide a kind of simple in structure, the maintenance easy accessibility easy to assemble split type high-pressure plunger pump.
The technical solution of the utility model is such: a kind of split type high-pressure plunger pump easy to assemble, comprise pump seat, high-pressure cylinder and plunger rod, and wherein: described pump seat and high-pressure cylinder socket connection are provided with seal ring between the surface of contact of pump seat and high-pressure cylinder.
Pump seat end face described in the above-mentioned easy to assemble split type high-pressure plunger pump is provided with columniform flange, and the external diameter of this flange and the internal diameter of high-pressure cylinder adapt, one side being plugged on this flange of high-pressure cylinder.
Above-mentioned easy to assemble split type high-pressure plunger pump can further be provided with the guiding copper sheathing in described pump seat, the guiding copper sheathing cooperates with plunger rod is movable.
Guiding copper sheathing described in the above-mentioned easy to assemble split type high-pressure plunger pump is installed in the counterbore at pump seat rear portion, is provided with Y shape O-ring seal, packing ring and circlip successively in the guiding copper sheathing outside, with replacing for convenience detach.
After the utility model adopts said structure, simple in structure by with being designed to socket connection between pump seat and the high-pressure cylinder, and also the replacing of high-pressure cylinder is convenient, easy; After further improving, because the copper sheathing that will lead is arranged in the pump seat, the guiding copper sheathing does not need to bear the ultra high water pressure in the high-pressure cylinder when work, under the equal conditions, can prolong the working life of copper sheathing more than one times of leading.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the utility model is described in further detail, but does not constitute any restriction of the present utility model.
Fig. 1 is the structural representation of a kind of specific embodiment of the utility model;
Fig. 2 is the structural representation of pump seat in the utility model.
Among the figure: pump seat 1, flange 1a, high-pressure cylinder 2, plunger rod 3, seal ring 4, guiding copper sheathing 5, Y shape O-ring seal 6, packing ring 7, circlip 8, pump cover 9, screw rod 10.
Embodiment
Consult Fig. 1, shown in Figure 2, a kind of split type high-pressure plunger pump easy to assemble of the present utility model, comprise pump seat 1, high-pressure cylinder 2 and plunger rod 3, be provided with columniform flange 1a at pump seat 1 end face, the external diameter of this flange 1a and the internal diameter of high-pressure cylinder 2 adapt, one side of high-pressure cylinder 2 is plugged on this flange 1a, is provided with seal ring 4 between pump seat 1 and high-pressure cylinder 2; Further also in pump seat 1, be provided with guiding copper sheathing 5, guiding copper sheathing 5 and 3 movable cooperations of plunger rod, guiding copper sheathing 5 in the present embodiment is installed in the counterbore at pump seat 1 rear portion, be provided with Y shape O-ring seal 6, packing ring 7 and circlip 8 successively in guiding copper sheathing 5 outsides, can after 4 wearing and tearing of guiding copper sheathing, change convenient like this.
When the utility model specifically uses, consult shown in Figure 1ly, be connected and fixed by four screw rods 10 between pump seat 1, high-pressure cylinder 2, plunger rod 3 and the pump cover 9, dismounting, easier for installation; Plunger rod 3 reciprocatingly moves along pump seat 1 and high-pressure cylinder 2 under the effect of external force (mechanical force or hydraulic coupling) during work, and water is sucked into and enters accumulator after high-pressure cylinder 2 compresses, and the said process that constantly circulates; Plunger rod 3 can stable operation under the leading role of guiding copper sheathing 4, and because the postposition of guiding copper sheathing 4 is avoided its alternation water pressure of bearing ultrahigh pressure, can prolong its working life greatly.
