Abstract
The utility model relates to a high-efficient pulp pump, belonging to the technical field of the pump. The high-efficient pulp pump is characterized in that a vane wheel is a complete open structure, a shaft gland adopts the combination of the pump auxiliary sealing and the single-end surface machine sealing, and a cooling water tube is provided. The technical proposal of the utility model can make the vane wheel have a larger passage, realizing no clogging. The combination of the auxiliary sealing and the single-end surface machine sealing can realize no leakage, so the utility model is the new type product of the existing pulp pump. The high-efficient pulp pump has the advantage of simple and reasonable structure.
Description
Technical field
The utility model relates to the pump technical field, relates in particular to a kind of efficient pulp pump.
Background technique
Domestic existing pulp pump structure adopts the logical nothing of double fluid to stop up pulp pump, half-opened impeller pulp pump, include two phase flow pulp pump, Characteristics of Centrifugal Pulp Pump, traditional packing seal, mechanical seal and sub-propeller sealing are adopted in sealing, therefore, this class pulp pump exists defectives such as efficient is low, the paper pulp passing capacity is not strong, sealing is unreliable, can't satisfy user's demand to greatest extent.
Summary of the invention
The purpose of this utility model is at existing pulp pump above shortcomings, and a kind of efficient, as not have advantages such as dielectric leakage, installation and maintenance convenience when the anti-plugging performance reaches operation well efficient pulp pump that has is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of efficient pulp pump, constitute by critical pieces such as the pump housing, impeller, main shaft, pump cover, machine end-blocking lid and suspensions, it is characterized in that impeller is the full-open type structure, impeller axial plane exit portion is parallel to each other, import department is diagonal flow type radially, the impeller outlet of cutting sth. askew during the impeller reducing, the distortion of blade inlet part is also protracted, the main shaft outer periphery of impeller one side is equipped with pump auxiliary seal and the combination of single end face machine envelope, and pump cover is provided with the water pipe that communicates with auxiliary seal and the combination of single end face machine envelope.
The utility model has produced following technique effect by taking technique scheme: 1, because impeller axial plane shape is parallel to each other, can prevent that medium is subjected to the jam phenomenon in circulation; 2, because the impeller outlet of cutting sth. askew makes front and rear cover plate streamline length near equating, to improve pump efficiency; 3, adopt the full-open type impeller, improved the stationarity of running, impeller is subjected to axial force and reduces; 4, impeller inlet is designed to diagonal flow type, can strengthen the radius of curvature of impeller axial plane import as far as possible, makes inlet blade angle bigger, and inlet space is big, can stop blocking phenomenon; 5, blade protracts, and can strengthen pump duty, improves pumping head, improves pump efficiency; 6, pump shaft envelope adopts auxiliary seal and the combination of single end face machine envelope, and can add and send the cooling sparge water, can realize that medium does not have leakage, the raising pump efficiency, and sealingly secure is reliable.
Blade inlet part attenuate in the impeller, and be circular shape, can improve the anti-plugging performance, the pump auxiliary seal can be the pumping ring or is whorl.
Description of drawings
Fig. 1 is the utility model sectional structure schematic representation.
Among the figure, the 1st, the pump housing, the 2nd, backplate, the 3rd, impeller, the 4th, back backplate, the 5th, pump cover, the 6th, auxiliary seal, the 7th, single end face machine envelope, the 8th, machine end-blocking lid, the 9th, suspension, the 10th, impeller nut, the 11st, water-cooling tube.
Embodiment
The utility model is made of critical pieces such as the pump housing 1, backplate 2, impeller 3, back backplate 4, pump cover 5, auxiliary seal 6, single end face machine envelope 7, machine end-blocking lid 8, impeller nut 10, water-cooling tube 11 and suspensions 9, impeller 3 is the full-open type structure, its axial plane exit portion is parallel to each other, import department is diagonal flow type radially, the impeller outlet of cutting sth. askew during the impeller reducing, the distortion of blade inlet part is also protracted, thereby guarantees that impeller has than major path, can realize not having and stop up; Pumping ring or whorl auxiliary seal 6 and 7 combinations of single end face machine envelope are adopted in sealing, and auxiliary seal is used for stoping medium to enter Seal cage; The position that the simultaneous pumping cooling water easily amasss the what medium by water-cooling tube 11 flushing impeller hub places, single end face machine envelope is used for sealing cooling water.
Claims (3)
1, a kind of efficient pulp pump, constitute by critical pieces such as the pump housing, impeller, main shaft, pump cover, machine end-blocking lid and suspensions, it is characterized in that impeller is the full-open type structure, impeller axial plane exit portion is parallel to each other, import department is diagonal flow type radially, the impeller outlet of cutting sth. askew during the impeller reducing, and the distortion of blade inlet part is also protracted, the main shaft outer periphery of impeller one side is equipped with pump auxiliary seal and the combination of single end face machine envelope, and pump cover is provided with the water pipe that communicates with auxiliary seal and the combination of single end face machine envelope.
