Abstract
The present invention relates to a liquid pump, in particular, it relates to a multi-channel impeller centrifugal pump. Said invention is composed of pump body, pump cover and pump shaft. On the described pump shaft at least one impeller whose interior is equipped with at least two channels is set, and a pump body sealing ring capable of preventing fluid medium from flowing out from said two channels is set in the correspondent position between inside of pump cavity of pump body and outlet ends of every two channels of said impeller.
Description
Technical field:
The present invention relates to a kind of liquid pump, particularly a kind of multi-runner type vane centrifugal pump is the liquid pump that needs centrifugal pump place first-selection.
Background technique:
Water pump is widely used in industry, agricultural and every field such as civilian, for development national economy had once been brought into play positive effect.But along with developing rapidly of science and technology, combination property to liquid pump requires also more and more higher, yet the impeller of centrifugar liquid pump in the past is the single channel formula, for satisfying the requirement of lift, a plurality of single channel formula impellers need be set in multistage pump, consequently the volume of pump increases, disc friction increases, and for the axial force of balance multistage pump, general pump efficiency will reduce 4-10%, for these reasons, centrifugal pump in the past has further improved necessity.
Summary of the invention:
The present invention is directed to the technical problem that prior art exists, provide a kind of compact structure reasonable, volume is little, and is in light weight, and disc friction is little, and is stable and reliable for performance, the multi-runner type vane centrifugal pump that rate of fault is low.
The present invention realizes that the technological scheme of goal of the invention is made up of the pump housing, pump cover and pump shaft, at least be provided with an impeller that has at least two runners in it on its described pump shaft, the pump chamber of the pump housing inboard with per two the runner exit ends of impeller between corresponding position be provided with and prevent the mixed mutually casing ring of two runners outflow medium.
The inlet of the described pump housing communicates with impeller first flow inlet, the outlet of each last runner communicates with the inlet of back one runner by the stationary flowpath that is provided with on the pump housing and the pump cover in the impeller, and the outlet of last runner is outwards carried highly pressurised liquid by the outlet on the pump housing.
Each runner of described impeller is axially analysed and observe for parallel or arranged in a crossed manner, the cover plate outside of last runner is provided with the back blades of balancing axial thrust, the position of wheel hub presses closer on the invagination right angle of axle sleeve and end face that the pump shaft shaft shoulder combines, and opposite side is installed on the pump shaft by impeller nut.
In the Seal cage that described pump cover and axle sleeve are formed, be provided with mechanical sealing assembly, the outside is fixed by mechanical seal cover.
Described pump shaft rear portion is provided with bearing, and places on the bearing suspended rack assembly, and the bearing outside is provided with bearing gland.
The present invention compared with prior art, owing to adopted a series of technical measures such as multi-runner type vane and casing ring, and axial force balance is arranged through evidence, disc friction is little, the pump efficiency height, and an impeller is equivalent to the lift of a plurality of impellers of same specification in the past, and volume is little, in light weight, save material, obviously reduce manufacture cost and operating cost.
