Description
Technical field
This utility model relates to a kind of pump, is 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 by filler with axle sleeve frictional heat by exporting outflow, 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 that axle sleeve is short for service life.
Summary of the invention
For solving deficiency of the prior art, the purpose of this utility model is in that providing a kind of utilizes negative pressure and hydraulic pressure isolation medium and a kind of light slurry pump simultaneously filler cooling rinsed.
For reaching object above, the technical scheme that this utility model is taked 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, described main shaft is socketed with axle sleeve, it is filled with filler assembly between axle sleeve and pump cover endoporus, described main shaft is provided with accessory impeller, 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 in pump cover hole end surface；Being respectively equipped with along the circumferential direction 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 the inner groovy of ring-type, the bottom of each radial direction through hole and inner groovy UNICOM；The intake tunnel of UNICOM's water proof circle and 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 the outer groove of ring-type, the top of each radial direction through hole and intake tunnel and outer groove UNICOM, described pump cover is provided with and channel attached water inlet and outlet.
After taking above technical scheme, the beneficial effects of the utility model are:
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 and axle sleeve gap when running, thus reaching spacer medium purpose, being prevented effectively from granule medium and entering 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, it is possible to maximum magnitude meets the basic demand of field condition.
The technical program may insure that under duty, medium does not enter packing seal cavity, thus extending gland sealed service life.

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.
Detailed description of the invention
