Description
Technical field:
The vertical sewage pump that the present invention has automatic exhaust device relates to the vertical sewage pump field.
Background technique:
In the vertical sewage pump in the past, the sewage that when opening, will get rid of by the sewage import of the spiral case of vertical sewage pump when the outlet of sewer of spiral case is discharged, in the inner chamber that mechanical seal is installed of bearing support, there is air, can't discharge, just cooling water can't enter in the inner chamber that mechanical seal is installed of above-mentioned bearing support, then mechanical seal is because dry operation produces dry friction, thereby producing high temperature damages mechanical seal, therefore, before pump startup, need earlier the air in the bearing support inner chamber be discharged by the people is manual,, mechanical seal is damaged because of the high temperature that dry friction produces if forget the above-mentioned air of eliminating.
Summary of the invention:
The purpose of this invention is to provide a kind of vertical sewage pump that has automatic exhaust device, by on bearing support, having mechanical seal coolant exhaust hole, make cooling water enter into the inner chamber of bearing support through mechanical seal coolant exhaust hole, make the air in the inner chamber can automatically be discharged from inner chamber, then can reach mechanical seal is cooled off and the purpose that is not damaged.
A kind of vertical sewage pump that has automatic exhaust device, it is made up of hoisting ring, rotor, mechanical seal, impeller, spiral case, mechanical seal coolant exhaust hole, bearing support, bearing and motor, the rotor that contains the motor of shell, stator is installed in the bearing inner race, in the rotor bottom mechanical seal and impeller is installed; Bearing Installation is in bearing support, and bearing support is connected with the shell of motor, and hoisting ring is installed on the bearing support, and spiral case is connected with bearing support by bolt; On bearing support, have mechanical seal coolant exhaust hole with its intracavity inter-connection; The spiral case lower end has the sewage import, has outlet of sewer in spiral case one side, has peep hole at the spiral case opposite side.
The automatic vent principle that the present invention has the vertical sewage pump of automatic exhaust device is described as follows, behind electric motor starting, the rotor impeller is rotated, cooling water by the sewage import of spiral case in mechanical seal coolant exhaust hole enters into the inner chamber that mechanical seal is installed of bearing support automatically, cooling water then can cool off the mechanical seal of operation, has guaranteed that the vertical sewage pump that originally has automatic exhaust device moves automatically.
Quiet of epitrochanterian mechanical seal and motion block just can not cause mechanical seal to damage because of dry friction forms high temperature in the bearing support inner chamber.
Mechanical seal coolant exhaust bore dia is in 10 to 20 millimeters; the mechanical seal exhaust port of minor diameter is directly cast and can't be cast like this; therefore; after bearing support is cast; by manually on bearing support, getting out above-mentioned mechanical seal coolant exhaust hole; so just can reach and to discharge the purpose of the air in the bearing support inner chamber again simultaneously with water quench, thereby protect mechanical seal, vertical sewage pump can normally be moved mechanical seal.
The present invention has the vertical sewage pump of automatic exhaust device, its motor consists predominantly of shell, stator and rotor, rotor is installed in the inner ring of bearing, Bearing Installation is in bearing support, the shell of bearing support and motor links together by attachment screw, on bearing support, also add hoisting ring, so that this vertical sewage pump is installed in lifting.
Impeller is installed on the lower shaft of rotor by key and nut; Mechanical seal is installed on the rotor on leaf top, is positioned at the bearing support lower lumen.
Spiral case is connected with bearing support by bolt, have the sewage import in the spiral case lower end, the spiral case lower end is connected with the supplying tube of sewage, has outlet of sewer in spiral case one side, be connected with waste pipe, sewage, is discharged by the sewage drainage pipe after the sewage supplying tube sucks by water pump again, also has the pressure gauge mounting hole on spiral case one side, measure the blowdown lift of pump for the setting pressure table, opposite side at spiral case has peep hole, i.e. hand hole is for the dirt of getting rid of in the spiral case.
The vertical sewage pump advantage that the present invention has automatic exhaust device is the air that can automatically get rid of in the bearing support inner chamber, need not exhaust manually, cooling water can be input in the bearing support inner chamber by mechanical seal coolant exhaust hole, mechanical seal is cooled off, thereby make the not high temperature that forms of reason dry friction and damaging of mechanical seal, can improve mechanical seal working life.
