The three-cylinder tailings stowing pulp pump plunger combination is characterized in that the plunger is of a hollow structure, and a hard alloy wear-resisting layer is sprayed on the surface of the plunger. In the core component of the three-cylinder tailings stowing pulp pump plunger combination, a hollow welding structure is adopted in the plunger, the hard alloy is sprayed on the surface of the plunger, and a secondary remelting technology is adopted, thus the surface hardness and the grain fineness are improved to reach the nano level, thus the abrasive resistance and the corrosion resistance of a quick-wear part are greatly improved, and the service life is prolonged. Meanwhile, a design of a packing is improved, a multi-material combination structure seal design is adopted, a specially-designed oil soaking ring is also adopted, the plunger and a sealing member are lubricated and cooled by using high-pressure oil provided with a peripheral mating gear oil pump, and a novel structure with the characteristics of corrosion resistance, abrasion resistance, ageing resistance, good self-lubricating performance and small friction coefficient is selected, so that the service life of a packing is longer.
Description
Technical field
The invention belongs to the conveying equipment for fluid substances technical field, particularly the improvement of stowing pulp pump plunger structure.
Background technique
Abroad begin adopt and select factory classified tailings carry out slush to the beginning of the fifties forties in 20th century.Exist the thin mud of excessive-20 μ m in this filling process, the surface that it stays the stope filling layering makes back production be difficult to carry out, and can't form the firm group's wall that can support oneself.After getting into the sixties in 20th century; Countries such as the U.S., Canada, Australia, Germany, the former Soviet Union and China; Developed new preparation, the conveying equipment of filling slurry; Add the application of trackless mining equipment, it is progressive hugely that consolidated fill technology has been obtained, and the appearance of mining with stowing is taken on a new look.But because the slip real quality concentration of using in the production reality generally is merely 60%～68%, in the stope dehydration, because segregation appears in slip; From the waste water that the stope diafiltration goes out, can take away part cement and fine particle stage material unavoidably, increase cement and run off, reduce strength of filling mass; Improve mining cost; Pollute operating environment, even more serious is that cement selects factory with the ore entering, brings harmful effect to ore dressing.To the seventies in 20th century, high concentration that Here it is or dense mortar cementitious filling are taken measures slip real quality concentration is brought up to more than 70%～78% in many mines.States such as China, Germany, South Africa, the U.S., Canada, Kazakhstan, Austria adopt different processes, have successively realized full tailings high concentration consolidated fill.It is the most extensive that this kind filling method is used, up to the present, in filling in mine still in the highest flight.Paste body filling is just to grow up in nearest more than 10 years, is one of new technology with high content of technology in the current mining industry.Filler is the mixture of full tailings or full tailings and rubble.This filling slurry need not dehydration; Reduced underground filling and polluted and effluent cost, strength of filling mass height and cement consumption are little, can reduce filling cost; Reduce the packing job cycle period; And filler is easy to connect the top, helps the stable and mining safety of stope, is the direction of mining with stowing technical development.
Full mine tailing filling effluxes the development trend that the environmental pollution that brings and mine tailing storehouse potential safety hazard become following mine tailing filling owing to alleviating mine tailing.On the other hand, for fully reclaiming underground resources, strengthen the ecological environmental protection dynamics, the method for mining by the way of filling has become the developing direction of modern underground mining technology, and it can prolong mine age, guarantees Mine Sustainable Development.But because old-fashioned filling process basically all is to utilize the manual work or the discrepancy in elevation to rely on method such as power gravity flow transportation for support mine tailing rubble or the filling slurry that stirs are delivered to the goaf; It is low to have manufacturing efficiency; Labor intensity is big, and diafiltration waste water dyes subsurface environment with thin dirt, and mine tailing and goaf can't connect the top; The tailings utilization ratio is low, shortcomings such as mining cost height.So it is imperative to research and develop new mining with stowing technology and filling slurry conveying equipment.The slurry pump that NB series filling pump is researched and developed for full tailings high concentration consolidated fill technology just; Can realize mine tailing high concentration, remote filling continuously; Further improve cemented fill intensity, be beneficial to stope filling and connect the top, be beneficial to the stope underground pressure management; Be beneficial to the abundant recovery of mining deposits, extremely important meaning arranged improving the mine tailing stowage capacity.
Summary of the invention
The present invention seeks to working medium and operating mode to NB type stowing pulp pump; In the filling slurry of height abrasion, high concentration, high pressure is carried; How to improve the working life of plunger and stuffing box packing, reduce the apparatus maintenance number of times, improve operation rate, thereby improve the reliability of equipment.
The combination of three cylinder mine tailing stowing pulp pump plungers is made up of plunger and the combination sealing arrangement on it, it is characterized in that plunger adopts hollow-core construction and surface to be coated with hard alloy abrasion-resistant layer.
Said combination sealing arrangement is installed on the plunger circumferential surface with Stuffing box, and Stuffing box one end seals with adjusting nut; Said combination sealing arrangement is made up of support ring, pressure ring, spacer ring and the mistake oil ring and the combined packing between said annular element that are enclosed within successively on the plunger.
Plunger adopts hollow welded structure in the core component of the present invention; Surface coated with hard alloy adopts the secondary remelting technology simultaneously, has improved surface hardness and fineness of grain reaches nanometer; Improve the wear resistance and the corrosion resistance of this easily damaged parts greatly, thereby prolonged working life.Improved the design of packing simultaneously; Adopt many materials composite structure Seal Design; The oil ring excessively of while unique design; Utilize high pressure oil that the peripheral matched gear oil pump provides that plunger and Sealing are lubricated and lower the temperature, select for use to have new material corrosion-resistant, wear-resistant, anti-aging, that self-lubricating property is good, friction ractor is little, make the longer service life of filler.
The present invention uses NB type filling triplex mud pump, and in the filling slurry of height abrasion, high concentration, high pressure was carried, the core component plunger adopted hollow welded structure; Surface coated with hard alloy; Adopt secondary remelting technology simultaneously, improved surface hardness and fineness of grain reaches nanometer, improve the wear resistance and the corrosion resistance of this easily damaged parts greatly; Improved the design of packing simultaneously; Adopt many materials composite structure Seal Design, simultaneously unique design cross oil ring, the high pressure oil that utilizes the peripheral matched gear oil pump to provide is lubricated plunger and Sealing and lowers the temperature; Select for use to have new material corrosion-resistant, wear-resistant, anti-aging, that self-lubricating property is good, friction ractor is little, make the longer service life of filler.Improve the working life of plunger and stuffing box packing, reduce apparatus maintenance number of times, raising operation rate, thereby improve the reliability of equipment thereby reach.
