Abstract
The invention relates to a light-duty slurry pump. An auxiliary impeller is mounted on a main shaft and located between a pump cover and a main impeller; an annular partition board is disposed between the auxiliary impeller and the main impeller and fixedly mounted on the end face of a pump body; a filler assembly comprises a water isolating ring, a filler, a water guide ring and a filler gland which are sequentially connected to the outer wall of a shaft sleeve in a sleeving mode in the axis direction of the main shaft; the water isolating ring is arranged on the side close to the auxiliary impeller; the water isolating ring and the water guide ring are in clearance fit with the shaft sleeve; the filler gland is connected to the inner hole end face of the pump cover; radial through holes which are uniformly distributed in the circumferential direction are formed in the water isolating ring and the water guide ring correspondingly; inner annular grooves are formed in the inner rings of the water isolating ring and the water guide ring, and the bottom end of each radial through hole communicates with the corresponding inner groove; water inlet channels which communicate with the water isolating ring and the water guide ring at the same time are formed in the pump cover; outer annular grooves are formed in the outer rings of the water isolating ring and the water guide ring, and the top end of each radial through hole and the water inlet channels communicate with the outer grooves; and a water inlet and a water outlet which are connected with the channels are formed in the pump cover.
Description
Technical field
The present invention relates to a kind of pump, be specifically related to a kind of light slurry pump.
Background technology
Pulp pump filler pump cover of the prior art is filler design of cooling water, and logical supercooled water enters water guide circle, water guide circle cooling water is carried out uniform, be diffused in packing sleeve surrounding, and filler is flowed out by outlet with axle sleeve frictional heat, it is achieved the derivation of heat.This Pulp pump filler pump cover design defect: frictional heat can only be taken away, but the granule medium abrasion to axle sleeve can not be effectively isolated, cause axle sleeve short for service life.
Summary of the invention
For solving deficiency of the prior art, it is an object of the invention to provide a kind of a kind of light slurry pump utilizing negative pressure and hydraulic pressure isolation medium and filler being cooled down flushing simultaneously.
For reaching object above, the technical scheme that the present invention takes is:
A kind of light slurry pump, including the pump housing, pump cover, main shaft and main impeller, main impeller is arranged in the pump housing, the side of the pump housing is sealed and installed with pump cover, main shaft is through pump cover endoporus and fixing with main impeller is connected, it is socketed with axle sleeve on described main shaft, it is filled with filler assembly between axle sleeve and pump cover endoporus, on described main shaft, accessory impeller is installed, described accessory impeller is between pump cover and main impeller, it is provided with toroidal membrane between described accessory impeller and main impeller, toroidal membrane is fixedly installed in the end face of the pump housing, described filler assembly includes the water proof circle being sequentially socketed on axle sleeve outer wall along main-shaft axis direction, filler, water guide circle and gland, described water proof circle is disposed in proximity to accessory impeller side, water proof circle and water guide circle all with axle sleeve matched in clearance, described gland is connected to hole end surface in pump cover；Being respectively equipped with the most uniform radial direction through hole on described water proof circle and water guide circle, the inner ring of water proof circle and water guide circle is equipped with ring-type inner groovy, the bottom of each radial direction through hole and inner groovy UNICOM；UNICOM's water proof circle and the intake tunnel of water guide circle simultaneously it is provided with in described pump cover, the outer ring of water proof circle and water guide circle is equipped with ring-type external groove, the top of each radial direction through hole and intake tunnel and external groove UNICOM, described pump cover is provided with and channel attached water inlet and outlet.
After taking above technical scheme, the invention have the benefit that
1. outside flushing water enters in pump cover cross over pipe by interface, flushing water is divided into two-way, a portion flushing water enters water proof circle, and enter axle sleeve and pump cover gap entrance pump chamber by water proof circle, because this Pulp pump designs for sub-impeller seal, accessory impeller produces negative pressure by the rotation of back blades when properly functioning, and flushing water has certain pressure of foundation, therefore flushing water can be immediately wicked into pump chamber by water proof circle and pump cover with axle sleeve gap when running, thus reach spacer medium purpose, it is prevented effectively from granule medium and enters filler cavity；Another part cooling water continues the heat that cooling shaft cover produces with filler spin friction, maintains basic refrigerating function
2. the design of this washing water is one-in-and-one-out, and the flow of washing water, pressure etc. are all had no special requirements by this invention, can meet the basic demand of field condition with maximum magnitude.
The technical program may insure that under duty that medium does not enter packing seal cavity, thus extends gland sealed service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the technical program；
Fig. 2 is the structural representation of water proof circle；
Fig. 3 is the structural representation of pump cover.
