Description
The invention belongs to the technical field of solid material pipelines hydraulic-transporting device.
Solid granular material (concentrate, mine tailing, bauxite, coal, lime-ash etc.) mixes with water and is solid-liquid two-phase flow, utilizes the pipe long-distance transportation to emerge in recent years, is considered to a kind of and the competitive material means of transportation of railway transport, by being paid attention to various countries.
At present, as the material transport pump, existing centrifugal pump, reciprocating pump, oil isolation pump and water isolation pump etc.
Centrifugal pump (sand pump, grey dredge pump, fertile graceful pump etc.) lift low (lift is less than the 90m water column) only is suitable for material short distance transportation.Level transportation iron tailings, pumping plant apart from be 2～3 kilometers/stand, than long-distance transportation, just need the multi stage pumping station series connection, the mine tailing that has at present transports and has been connected in series to nine grades of pumping plants.Because slurry directly enters quick abrasions such as the pump housing, impeller, backplate, make the life-span of pump short, maintenance expenses is high, efficient is low, these problems will improve and aggravate along with slurry concentration.
Reciprocating pump (plunger pump, reciprocating pump, diaphragm pump) flow is little, and peak rate of flow is 200 cubic metres/hour usually.This pump structure complexity, maintenance difficult.Because slurry enters the diaphragm pump pump housing, enters plunger pump, reciprocating pump pumping cylinder, makes guide pin bushing, piston rod, check valve etc. become easily damaged parts, short and replacing difficulty of life-span, maintenance expenses height.
Oil isolation pump is called the Ma Ersi pump again.This pump is a kind of distortion of reciprocating pump, and it separates oil and ore pulp by isolation tank, prevents that slurry from entering pumping cylinder, has improved the life-span of pump.But this pump, also exists the suspended matter in the slurry to sneak into the phenomenon that enters pumping cylinder in the oil, thereby causes oil consumption so existing fluid runs off owing to be to take oil directly to contact with slurry, reduces the working life of pump again.Because oil is reliable inadequately with the level control that slurry directly contacts, often cause a large amount of loss of fluid, befouling environment again.And flow is little, is unsuitable for big flow slurry transportation.
Water isolation pump is called hydraulic elevator again.This pump, water and slurry are isolated by ball float, because ball float and tank skin are gapped, the clear water leakage are arranged, so clear water can not closed-circuit; Also often there is the slurry of mixing phenomenon to occur, so need establish clear water reserviors.In order to prevent that ball float from blocking, this pump can not transport particle diameter greater than 2 millimeters solid material.This pump need have complicated detection and control system for the position of controlling ball float and the speed of related movement of regulating three ball floats, has increased the complexity and the expense of equipment.
