Abstract
The utility model relates to the technical field of centrifugal pumps, in particular to a water-cooling heat-dissipating protection system of a shaft seal of a centrifugal pump. The water-cooling heat-dissipating protection system comprises a pump shell, an impeller shell chamber, a pump shaft, the shaft seal and a bearing box, wherein a cooling water feeding line is connected with a coil pipe inlet inside the bearing box, a shaft seal outer end chamber inlet, and a heat exchanger shell pass inlet respectively; a cooling water returning line is connected with a coil pipe outlet, a shaft seal outer end chamber outlet and a heat exchanger shell pass outlet respectively. The water-cooling heat-dissipating protection system is reasonable in structure and simple in operation. In the practical application, the water-cooling heat-dissipating protection system can effectively conduct heat dissipation on the shaft seal, prolong the service life of the mechanical seal of the type of pumps, reduce the maintenance times of the pump and keep water in a tail end cooling water branch plentiful, and brings a guarantee to the stable operation of the system.
Description
Technical field
The utility model relates to centrifugal pump technical field, relates in particular to a kind of centrifugal pump seal water-cooling protective system.
Background technique
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 sleeve, and then starting electrical machinery, 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 during actual use, often there will be some problems.For example, when 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, when 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.
Model utility content
The utility model is intended to for the deficiency existing in background technique, and a kind of centrifugal pump seal water-cooling protective system is provided.
Centrifugal pump seal water-cooling protective system of the present utility model, comprise and draw together pump case, impeller housing chamber, pump shaft, shaft seal and bearing housing, 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 further improvement of the utility model, 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 further improvement of the utility model, the described cooling upper waterline being connected with shaft seal outer end chamber entrance is provided with restriction orifice.
Centrifugal pump seal water-cooling protective system of the present utility model; reasonable in design, easy to use; the design of restriction orifice; having guaranteed 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 working life of this type of pump mechanical sealing; reduced the maintenance number of times of pump, made end cooling water branch road abundant water, for system is steadily normally moved and brought guarantee.
