Abstract
Disclosed is a single-suction multi-section centrifugal pump, comprising a motor, a pump body, a one-way inlet valve, a one-way outlet valve and a control mechanism for controlling the valves to be on and off. The pump body is composed of multi-section unit pump liquid seals; a left bearing support and a right bearing support which are connected with a drive shaft are correspondingly arranged at both ends of the pump body; both ends of the pump are also provided with a left cooling case and a right cooling case taken as end covers of the pump; the two cooling cases are connected with the pump body seals. The cooling cases used as the seal end covers are added at both sides of the pump body and corresponded to the bearing supports. The bearing supports are communicated with the cooling cases by pipes, the bearing supports are directly and indirectly cooled circularly by the cooling water flowing through the bearing supports and the cooling cases, the influence of high temperature pump body on the bearings in the bearing supports is reduced; thereby the bearings are not easily damaged and the service lives of the bearings are indirectly improved. No special design is necessary for the pump body structure; the utility model has simple process and low production cost.
Description
(1) technical field
The utility model relates to a kind of centrifugal pump.
(2) background technique
Existing centrifugal pump does not have cooling unit between the pump housing and the bearing support, and the adjacent pump housing discharges a large amount of heats and conducts to the bearing support middle (center) bearing by transmission shaft, and the bearing support middle (center) bearing that is in for a long time under the hot environment is easily impaired, and working life is short; China Patent No. is: 200610050344.9 disclosed a kind of centrifugal pumps, and by directly indent design in pump housing end being formed cooling chamber, the centrifugal pump manufacturing process complexity of this structure, manufacture cost height.
(3) summary of the invention
In order to overcome the deficiency of existing centrifugal pump, the utility model provides a kind of bearing support middle (center) bearing to be difficult for impaired and the simple centrifugal pump of manufacturing process.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of single suction multi-section type centrifugal pump, comprise the control mechanism that motor, the pump housing, unidirectional inlet valve, unidirectional outlet valve, control valve open and close, the described pump housing is made up of multistage modular pump liquid sealing, described pump housing two ends correspondence is provided with left shaft holder, the right bearing seat that is connected with transmission shaft, described pump housing two ends are respectively equipped with the double left cooler bin of end cap, the right cooler bin done, and the described cooler bin and the pump housing are tightly connected.
The right bearing seat is provided with cooling water intake, described right bearing seat is communicated with by conduit with adjacent right cooler bin, described right cooler bin is communicated with the left shaft holder of the other end by being positioned at the outer conduit of the pump housing, left shaft holder is communicated with left cooler bin by conduit again, and described left cooler bin is provided with coolant outlet.
The beneficial effects of the utility model mainly show: 1, add the cooler bin that can doublely do pump housing end cover in the pump housing both sides of bearing support corresponding position, bearing support, cooler bin pass through pipeline connection, the cooling water that runs through bearing support, cooler bin carries out direct and indirect circulation cooling to bearing support, reduced of the influence of the high temperature pump housing to the bearing support middle (center) bearing, the bearing support middle (center) bearing is difficult for impaired, has improved working life indirectly; 2, need not pump body structure is carried out particular design, manufacturing process is simple, low cost of manufacture.
(4) description of drawings
Fig. 1 is the overall structure schematic representation.
(5) embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to accompanying drawing 1, a kind of single suction multi-section type centrifugal pump, comprise the control mechanism that motor 1, the pump housing 2, unidirectional inlet valve 4, unidirectional outlet valve 5, control valve open and close, the described pump housing is made up of multistage modular pump 21 liquid sealings, described pump housing two ends correspondence is provided with left shaft holder 61, the right bearing seat 62 that is connected with transmission shaft, described pump housing two ends are respectively equipped with double left cooler bin 31, the right cooler bin 32 of doing end cap, and the described cooler bin and the pump housing are tightly connected.The right bearing seat is provided with cooling water intake 7, described right bearing seat is communicated with by conduit 81 with adjacent right cooler bin, described right cooler bin is communicated with the left shaft holder of the other end by being positioned at the outer conduit 83 of the pump housing, left shaft holder is communicated with left cooler bin by conduit 82 again, and described left cooler bin is provided with coolant outlet 9.
Claims (2)
