Abstract

The present invention relates to centrifugal pump technical field, relate in particular to a kind of centrifugal pump seal water-cooling protection system, comprise pump case, impeller housing chamber, pump shaft, shaft seal and bearing housing, cooling upper waterline is connected respectively at the coil pipe entrance in bearing housing, shaft seal outer end chamber entrance, heat exchanger shell pass entrance; Cooling water backwater line is connected with coil pipe outlet, the outlet of shaft seal outer end chamber, heat exchanger shell pass outlet respectively. The present invention is rational in infrastructure, simple to operate. In actual application, the present invention can be shaft seal heat radiation effectively, and the service life of long this type of pump mechanical sealing, has reduced the maintenance number of times of pump, makes end cooling water branch road abundant water, for system even running has brought guarantee.

Description

Centrifugal pump seal water-cooling protection system
Technical field
The present invention relates to centrifugal pump technical field, relate in particular to a kind of centrifugal pump seal water-cooling protection system.
Background technology
Centrifugal pump is utilize vane rotary and make the centrifugal force of water generates carry out work. Water pump, before startup, must make to be full of water in pump case and suction hose, and then starter motor makes pump shaft impeller and water do high speed rotary motion, and water, under the effect of centrifugal force, is thrown toward impeller outer edge, flows into the setting-out pipeline of water pump through the runner of volute pump case. At present utilization rate is high aborning for centrifugal pump, but now in factory when actual use, often there will be some problems. For example, in the time that shaft seal is cooling, often occur cooling not in time, not thorough, cool position is selected the problems such as not good. Friction pair between the bad very easily damage of cooling effect machine envelope dynamic and static ring, thus mechanical seal destroyed, cause pump normally to work. Particularly, in the time of chilled(cooling) water supply (CWS), do not control the valve of flow, the cooling water of end branch is difficult to the abundance of guaranteeing supply, if the slightly high cooling water of water level is just difficult to arrive more, affects the cooling effect of shaft seal.
Summary of the invention
The present invention is intended to for the deficiency existing in background technology, and a kind of centrifugal pump seal water-cooling protection system is provided.
Of the present inventionCentrifugal pump seal water-cooling protection system, comprises and draws together pump case, impeller housing chamber, pump shaft, shaft seal and bearing housing, and in its system, cooling upper waterline is connected respectively at the coil pipe entrance in bearing housing, shaft seal outer end chamber entrance, heat exchanger shell pass entrance; Cooling water backwater line is connected with coil pipe outlet, the outlet of shaft seal outer end chamber, heat exchanger shell pass outlet respectively.
As a further improvement on the present invention, wherein the tube side of heat exchanger outlet is connected with the inner chamber entrance of shaft seal in pump case, and the inner chamber of shaft seal exports through impeller housing chamber to pump discharge and is connected with the tube side entrance of heat exchanger.
As a further improvement on the present invention, the described cooling upper waterline being connected with shaft seal outer end chamber entrance is provided with restriction orifice.
Centrifugal pump seal water-cooling protection system of the present invention; reasonable in design, easy to use; the design of restriction orifice; having ensured the flow uniform distribution of each pipeline, thereby realized the effective cooling of pump mechanical sealing, can be shaft seal heat radiation effectively; extend the service life of this type of pump mechanical sealing; reduce the maintenance number of times of pump, made end cooling water branch road abundant water, for system is steadily normally moved and brought guarantee.
