Abstract
The utility model relates to a self-sucking and turbulence non clogging drainage pump which is composed of a pump body, a pump cover, an impeller, a pump shaft, a seal component and an installation component. The utility model is characterized in that a turbulence chamber and an impeller chamber which are communicated with each other are fabricated in the pump body, blades are uniformly distributed on a chassis of the impeller, the radial central line of the turbulence chamber is formed on the central line of a pump outlet, and thus, media can be directly led to the outlet from an inlet through the turbulence chamber. A phenomenon that an impeller passage of the existing product is easy to be clogged is eliminated, operational reliability is enhanced, and the utility model is especially suitable for draining and pumping solid particles, fibres, thick slurry and highly concentrated media of various kinds of industry.
Description
The utility model relates to a kind of pump, specifically about a kind of self-priming no-blocking pollution discharging pump.
Self-priming no-blocking pollution discharging pump is a kind of waste removal equipment of pumping media such as solid particle, fiber, slurry and mix suspending in the industries such as light industry, papermaking, weaving, food, oil, chemical industry, mine, municipal administration that is applicable to, it comprises the pump housing, pump cover, impeller, pump shaft, bearing, holds shaft-cup and Sealing.At present, the impeller of domestic common pollution discharge pump has single channel and two kinds of forms of Twin channel, and the radial centre lines of blade wheel chamber and pump discharge are on same axis, and this pollution discharge pump can be inhaled and send general pulpous state fluid.But because medium sends through impeller passage, when sending the bigger medium of concentration for suction, its impeller passage stops up easily, thereby makes the pollution discharge pump operational failure.
The purpose of this utility model is a kind of nonclogging self-priming pollution discharge pump fully of design.
The purpose of this utility model is achieved in that not blocking pollution discharging pump of a kind of self-priming eddy current, comprise the pump housing, pump cover, pump shaft, impeller, bearing, bearing cap, Sealing and assembling set, be shaped on blade wheel chamber and vortex chamber in the pump housing, the diameter of vortex chamber is greater than the true footpath of blade wheel chamber, its radial centre lines is on pump housing outlet axis, the front, chassis of impeller is uniform-distribution with the blade more than 4, blade divides inside and outside two sections, inner segment front side of vane and this working surface hand over the normal by a place to acutangulate with the impeller hub cylindrical, outer section front side of vane and this normal parallel.
The utility model beneficial effect compared with prior art is to be shaped in the pump housing vortex chamber and blade wheel chamber, blade wheel chamber is not on the outlet axis, impeller is made of uniform blade on the chassis, by the eddy current that wheel rotation produces flowing medium is directly carried to outlet through the vortex chamber from import, the course of conveying medium is not passed through impeller all the time, thereby make the utility model not have impeller blocking phenomenon, reliable operation.
Fig. 1 is a structure erection drawing of the present utility model.
Fig. 2 is the structure sectional view of the utility model impeller.
Fig. 3 is the blade distribution map of the utility model impeller.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.Self-priming eddy current shown in Figure 1 is blocking pollution discharging pump not, comprise the pump housing 1, pump cover 2, impeller 3, pump shaft 4, bearing 6 and 7, bearing cap 8, Sealing and assembling set, between the import of the pump housing 1 and the outlet vortex chamber is arranged, its radial centre lines is on center line of discharge, be communicated with a diameter than its little blade wheel chamber in the inboard of vortex chamber, impeller 3 is by in the fixing blade wheel chamber of pump shaft 4, evenly distribute 4 on the chassis of impeller 3 shown in Figure 3 with upper blade 5, the quantity of blade 5 increases with the increase of pump latus rectum.Inside and outside the blade 5 minutes two sections, inner segment working surface and this working surface acutangulate with the normal at impeller hub cylindrical interface point place, and its angle is advisable with 10 °-50 °, and the best is 30 °, outer section working surface and this normal parallel.Pressure when the thickness of blade 5 is worked can bear pollution discharge pump is advisable.
Claims (2)
1, a kind of self-priming eddy current blocking pollution discharging pump not, comprise the pump housing, pump cover, impeller, pump shaft, bearing, bearing cap, Sealing and assembling set, it is characterized in that being shaped in the described pump housing (1) vortex chamber, the radial centre lines of vortex chamber is on pump housing outlet axis, in the blade wheel chamber that impeller (3) is contained in the vortex chamber is communicated with, the diameter of vortex chamber is greater than the diameter of blade wheel chamber; Evenly distribute 4 on the positive chassis of described impeller (3) with upper blade (5), inside and outside two sections of blade (5) branch, inner segment working surface and this working surface acutangulate with the normal at impeller hub cylindrical interface point place, outer section working surface and this normal parallel.
2, self-priming eddy current according to claim 1 blocking pollution discharging pump not, the working surface that it is characterized in that described blade (5) inner segment and this working surface are with becoming 10 ° of-50 ° of angles between the outer normal of impeller hub cylindrical interface point, and the best is 30 °.
