Abstract
The invention relates to a large circulating pump with a bearing box cooling device. The pump comprises a pump body, wherein a water inlet and a water outlet are formed in the pump body; an impeller is installed in the pump body; the impeller is connected to a spindle; a bearing box is installed on one side of the pump body; the bearing box and the pump body are separated by a pump cover area; the spindle successively passes through the bearing box and a pump cover; and a seal assembly is disposed at the joint between the pump cover and the spindle. The pump is characterized in that a front water seal plate and a rear water seal plate are disposed on two ends of the bearing box respectively; two independent circular cooling chambers are formed and enclosed within the front and rear water seal plates and the box wall of the bearing box respectively; bottoms of the two cooling chambers communicate by a cooling water communicating pipe; a water inlet is formed in the top face of the cooling chamber at the front end; a water outlet is formed in the top face of the cooling chamber at the rear end; and multiple baffles disposed at intervals are disposed on the inner walls of the cooling chambers.
Description
Technical field
The present invention relates to a kind of circulating pump, be specifically related to the large-scale circulating pump of a kind of band cooling device for bearing housing.
Background technology
Circulating pump is that a kind of industries such as electric power, Coal Chemical Industry, environmental protection that are widely used in process for desulphurization and denitration and waste water
Multipurpose chemical pump.Large desulfurization pump bearing axial force and radial force all have bigger load, can produce substantial amounts of heat in bearing housing
Amount, if can not effectively dispel the heat be easily caused the damage of bearing, affects the use of pump.
Summary of the invention
It is an object of the invention to provide the large-scale circulating pump of a kind of band cooling device for bearing housing.
The technical scheme that the present invention takes is:
The large-scale circulating pump of a kind of band cooling device for bearing housing, including the pump housing, the pump housing is provided with water inlet and outlet, in the pump housing
Being provided with impeller, impeller is connected with rotating shaft, and the side of the pump housing is provided with bearing housing, is separated by pump cover between bearing housing and the pump housing, institute
Stating rotating shaft and sequentially pass through bearing housing and pump cover, pump cover and rotating shaft junction are provided with black box, and the two ends of described bearing housing are respectively
It is provided with front water shutoff plate and rear water shutoff plate, encloses respectively between the tank wall of described forward and backward water shutoff plate and bearing housing and be connected into two independent rings
Shape cooling chamber, the bottom of two cooling chambers is by cooling down water cross over pipe UNICOM, and the cooling chamber end face of described front end is provided with water inlet, after
The cooling chamber end face of end is provided with outlet, and described cooling chamber inwall is provided with the spaced baffle plate of polylith.
Further, described cooling chamber inner ring wall being provided with two pieces of baffle plates, two baffle plates are distributed in the left and right two of water inlet
Side, left side baffle plate and inwall gap, cooling chamber outer ring are more than right-hand apron and the gap of cooling chamber outer ring inwall.
After taking above technical scheme, the invention have the benefit that and be designed with before and after's chiller at bearing housing two ends,
The dependability of elevator pump.Front cooling chamber is to have front water shutoff plate to form a front cooling chamber with bearing housing, and rear cooling chamber is by rear
Water shutoff plate and bearing housing form rear cooling chamber；Two cooling chambers are carried out UNICOM by cooling down water cross over pipe.Cooling water is by cooling water inlet
Enter cooling chamber, logical supercooled water communicating pipe carry out UNICOM with cooling chamber, then flowed out by coolant outlet, it is achieved cooling.Cooling
Chamber is designed with long short shutter, is arranged according to certain angle and quantity and gap, is possible to prevent to cool down water and directly enters from import
Such as communicating pipe, add the contact area with bearing bore and time, improve but effect.
