Abstract
The utility model relates to a pump rotor, in particular to a multilevel push type centrifugal impeller for the pump, which comprises an impeller hub and an impeller cover connected with each other. Wherein, the impeller is provided with a communicated impeller water inlet end inner chamber and an impeller inner chamber as well as the multilevel blade; of which, the first level blade is positioned inside the impeller water inlet end inner chamber, the second and the third blades are inside the impeller inner chamber, specifically on the edge for the third one; the impeller water inlet end inner chamber is a protuberant conical cavity composed of the impeller hub and the impeller cover. With the adoption of the three level blades push type accelerating structure, the impeller increases the liquids' centrifugal pull and outflow speed and can be widely applied on the centrifugal pump, the horizontal submersible pump and the liquid transfer pump.
Description
Technical field
The utility model relates to the multistage pusher centrifugal impeller that a kind of rotor of pump, particularly pump are used.
Background technique
The centrifugal impeller of the pump that uses has only one group of (level) blade at present, the water that will be taken out when impeller rotates pressurization output.The pumping impeller of daily submersible pump is to keep flat when using, and the current that pump need to turn 90 ° and go to vertical direction and flow by substantially horizontal is anxious, thereby elbow is set, and increase resistance to water-flow, and cause the hydraulic pressure recoil force to strengthen, so high-head pump can not be done the low-lift pump use.
Summary of the invention
The purpose of this utility model provides the multistage pusher centrifugal impeller that pump that multistage blade is housed on a kind of impeller is used, and current vertically are installed are become parabola to dish out.
The utility model is finished with following mode: connected and composed by impeller boss and impeller cover, blade is housed in impeller.Impeller has impeller feed-water end inner chamber and the impeller inner chamber that is connected, multistage blade is housed in the impeller, first order blade installation is in impeller feed-water end inner chamber, second level blade and third level blade installation are in the impeller inner chamber, third level blade installation position is at the edge of impeller inner chamber, and impeller feed-water end inner chamber is the frustoconic shape cavity of the protrusion that is made of impeller hub and impeller cover.First order blade shape is the oar type in the shape of a spiral, and its blade quantity has 3 to 6.Second level blade shape is parabolic shape or involute-type, and its blade quantity has 27 to 54.First order blade quantity and second level blade quantity and third level blade quantity be 1: 1: 9 than the ratio of greater inequality value.
This impeller is provided with multistage blade, and after suction entered impeller, water increased the initial velocity that water flows into second level blade through first order blade axial advance, and the water through quickening is dredged down at first order blade angle of deflection, enters second level blade at a high speed.Water enters third level blade through the further speedup of second level blade, is further speedup, and third level blade quantity is the several times of second level blade quantity, to increase the fluid surface of contact, the biography speed that helps power strengthens the angle of dishing out of blade simultaneously, promotes the centrifugal speed that fluid (water) is dished out.Because impeller adopts the laddering accelerating structure of three grade blades, fluid centrifugal force and outlet velocity in impeller are increased greatly.This impeller can be widely used in centrifugal pump, horizontal submersible pump, and liquid delivery pump uses.
Description of drawings
The multistage pusher centrifugal impeller master that Fig. 1 pump is used looks schematic representation.
Fig. 2 is the A-A cross-sectional schematic of Fig. 1.
Embodiment
The multistage pusher centrifugal impeller that pump is used has three grade blades, and every grade blade is installed in diverse location, thereby becomes three grade blades are arranged.First order blade quantity has 3 to 6, and blade 3 quantity in the second level have 3 to 6, and third level blade 4 quantity have 27 to 54.Present embodiment adopts the more excellent ratio of three grade blade quantity, and first order blade 2 has 4, and blade 3 quantity in the second level have 4, and third level blade 4 quantity have 36, and promptly their ratio is 1: 1: 9.
Impeller hub is connected the back internal cavities and is divided into two inner chambers that are connected with impeller cover, promptly impeller feed-water end inner chamber 6 and impeller inner chamber 7 flow through liquid (water) when being used to install blade and use.The frustoconic shape cavity of the protrusion that impeller hub 1 and bucket cover 5 constitute is an impeller feed-water end inner chamber 6, dress first order blade 2 in it, and blade shape is the oar type in the shape of a spiral.Second level blade 3 and third level blade 4 are contained in the impeller inner chamber 7, blade 3 shapes in the second level are parabolic shape, the first order blade 2 of its blade-section length in the impeller feed-water end inner chamber 6, accept during the work running water that flows at a high speed from the pushing of first order blade and by second level blade with water in impeller inner chamber 7 again speedup flow to third level blade 4 at a high speed.Third level blade 4 is contained in the edge of impeller inner chamber 7, the angle of dishing out of blade strengthens, because blade quantity is more, increased the surface of contact of blade and water, help the transmission of power, third level blade 4 is accepted to extrude impeller with high-voltage high-speed again from the water of second level blade 3 high speed inflows, and water advances pressurization to quicken through three grades in blade in impeller.Water flows into the end flow pipe from impeller in use.First order blade 2 and second level blade 3 are side by side mode and arrange that second level blade 3 and third level blade 4 are the in-line arrangement mode and arrange in impeller inner chamber 7 in impeller.Impeller of the present utility model has axis hole 8, uses so that running shaft is installed when using.
When the utility model impeller uses at horizontal submersible pump, the horizontal placement of the motor of pump, impeller is vertical installation, and the conduit pipe of water delivery straight up can be tangent direction with impeller and be connected.The fluid of being dished out by impeller during work (water) is tangent direction takes advantage of a situation and is pressed into the vertical conduit pipe of upwards water delivery, needn't install 90 ° elbow guiding additional in the joint, situation when hydraulic pressure and water velocity keep dishing out from impeller substantially, reduce the recoil pressure of current greatly, help strengthening the high low lift of horizontal submersible pump and using impeller.
