Description

The rotary flow type Non-blinding pump

Technical field

The utility model is a kind of pump, particularly a kind of rotary flow type Non-blinding pump that mainly is applicable to the medium transport that contains large particle solid matter (as wood chip, unit of plastic etc.), long fibre (as the rag in the secondary stock, straw rope, nylon rope, plastic film etc.), high air content, viscosity height or easy damaged in the light industry paper industry.

Background technique

Carry the medium that contains larger particles solid matter, long fibre, viscosity height or easy damaged mainly to adopt following technology in the prior art in the light industry paper industry:

Adopt one step single sucking passage pump to carry out pumping, (impeller channel is circular or square though with the impeller of channel-type structure, be generally 2 enclosed runners), its conveyance capacity is stronger, thus medium must flow through this impeller could pumping, impeller thus can wear and tear, pump-conveying property is descended, impeller shortens working life greatly, and mean lifetime was generally 3 months, made troubles to use; This impeller volume is big, and weight is heavier, and operation stability is certainly less better, and medium that can not the high air content of pumping, and therefore, there is certain narrow limitation in the use in this one step single sucking passage pump.

Summary of the invention

The utility model mainly is to solve the deficiencies in the prior art, a kind of conveyance capacity that improves pump is provided, pump can be successfully carried for a long time contain the medium of large particle solid matter (as wood chip, unit of plastic etc.), long fibre (as the rag in the secondary stock, straw rope, nylon rope, plastic film etc.), high air content, viscosity height or easy damaged; Prolong the working life of rotary flow type impeller; Improve the rotary flow type Non-blinding pump of pump beautiful shape and coupling barrier propterty.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:

A kind of rotary flow type Non-blinding pump, comprise the pump housing, be provided with impeller in the described pump housing, described impeller is the rotary flow type impeller, described rotary flow type impeller comprises wheel body, axis hole, long rotary flow type blade and short rotary flow type blade, the centre of described wheel body is provided with axis hole, and the described surface of taking turns is provided with long rotary flow type blade and short rotary flow type blade, and described long rotary flow type blade and short rotary flow type blade are distributed on the wheel body.

Pump when rotated, can form in the no phyllocyst of rotary flow type impeller front and connect stream (axial flow) and circular flow, connecting stream flows out by the pump chamber that long rotary flow type blade on the impeller and the interlobate runner of short rotary flow type enter in the pump housing, circular flow then circulates in no phyllocyst, because the circular flow middle part is a low pressure area, media such as long fibre or solid particle are fallen into this district and can be flowed out under the drive of eddy flow, therefore, most of long fibre or solid matter etc. can directly flow out from no phyllocyst without the rotary flow type impeller, make difficult obstruction of pump or easy damaged medium not.In addition, the back blades on the rotary flow type impeller works mainly to prevent that small amount of impurities from entering axle envelope and balancing axial thrust.

As preferably, the back side of described wheel body is provided with back blades, and described back blades is corresponding with long rotary flow type blade and short rotary flow type blade, and the quantity of described back blades equates with long rotary flow type blade and weak point rotary flow type blade quantity sum; Be provided with no phyllocyst in the described pump housing, described no phyllocyst and impeller are complementary.

As preferably, the surface of described wheel body is provided with 4 long rotary flow type blades, and described long rotary flow type blade contacts with the axis hole outward edge, is respectively equipped with a short rotary flow type blade between every long rotary flow type blade; Described no phyllocyst is strip.

As preferably, described short rotary flow type blade is located at the interlobate interposition of long rotary flow type, and the corresponding end with axis hole of described short rotary flow type blade is a beveled end, described beveled end and the transition of wheel body surface smoothing.

As preferably, described long rotary flow type blade is skewed.

As preferably, the quantity of described back blades is 8 to 12, and the quantity of described long rotary flow type blade and short rotary flow type blade is respectively 4 to 6.

Therefore, the rotary flow type Non-blinding pump that the utility model provides, no plugging performance is good, easy damaged medium not, rotary flow type impeller not easy to wear, the rotary flow type impeller weight is light, and pump operation is steady, long service life, maintenance expenses is low.
