Description
Technical field
The invention belongs to slurry pump technical fields, and in particular to a kind of high-lift multi-stage Pulp pump.
Background technique
Pulp pump, which refers to, says that finger makes solid, liquid blending agent energy by the effect by centrifugal force (rotation of the impeller of pump)
A kind of increased machinery, converts electric energy to the kinetic energy of medium and the equipment of potential energy.Be primarily adapted for use in: mine, power plant, dredging,
The industry fields such as metallurgy, chemical industry, building materials and petroleum, its working principle is that: under the influence of centrifugal force, liquid is from impeller center quilt
It throws to outer rim and obtains energy, enter volute pump case to leave impeller outer edge at a high speed.In volute pump case, liquid is due to runner
It is gradually expanded and slows down, and part kinetic energy is changed into static energy, discharge line is finally flowed into higher pressure, is sent to needs
Place.When liquid flows to outer rim by impeller center, certain vacuum is formd in impeller center, due to the pressure of storage tank ullage
Power is greater than the pressure at pump intake, and liquid is just continuously pressed into impeller, and common slurry pump configuration is as follows: pump head framework.Pump
Body is vertical middle open type using the double-deck pump case (inside and outside double-layer metal structure), double pump shell shell mechanism, and water outlet position can be by 45 °
Interval, rotates 8 different locations and installs and uses.It is close using dynamic seal, packing seal or machinery to effectively prevent axle envelope to reveal
Seal combining form.Impeller and rear backplate are asked to be sealed equipped with labyrinth gap, significantly reduces slurry to stuffing box amount of leakage, has
It ensure that power the reliability of sealing.Impeller is equipped with back blade, and the slurry of discharge reflux in time reduces to improve plot ratio
Reflux and erosion, improve the flow passage components service life.It is equipped with stripping ring for easy access and disassembly, is avoided due to cannot dismantle
It causes to cut axis phenomenon；Carrier structure.Carrier structure is horizontal middle open type, for the service life for extending bearing, from the Hydraulic Design and
It is optimized in structure design.Make radial force and axial force reasonable layout, and correctly select bearing type, model, cooling with
Lubricating system etc., to reach the low fever of bearing, the requirement of high life；Axle envelope form.Gland seal device to the pump housing and pump shaft it
Between seal.It can prevent from leaking out out of pump in air intrusion pump with a large amount of water.The seal form of Centrifugal Slag Pump is logical
Frequently be the filled sealing of accessory impeller, the filled sealing of accessory impeller is hydrodynamic seal, the pressure head generated by accessory impeller
The leakage of impeller outlet liquid is resisted, while setting back blade using impeller cover and seal cage and filler is added to prevent air from entering,
The pressure at filler is reduced with back blade and seal cage again, prevents impurity from entering sealing, Multi-stage slag traditional at present
There are still various problems for stock pump.
The Multi-stage slag-slurry pump as disclosed in the invention that Authorization Notice No. is CN204061201U, can make the grade of Pulp pump
