Abstract
The invention relates to the technical field of centrifugal pumps, in particular to a shaft-seal water-cooling heat dissipation protecting system of a centrifugal pump. The shaft-seal water-cooling heat dissipation protecting system comprises a pump shell, an impeller shell, a pump shaft, a shaft seal and a bearing housing, wherein a cooling water feeding line is respectively connected with the inlet of a coil pipe inside the bearing housing, the inlet of a chamber at the outer end of the shaft seal and the inlet of a shell side of a heat exchanger; a cooling water return line is respectively connected with the outlet of the coil pipe, the outlet of the chamber at the outer end of the shaft seal and the outlet of the shell side of the heat exchanger. The shaft-seal water-cooling heat dissipation protecting system is reasonable in structure and easy to operate. In actual application, the shaft-seal water-cooling heat dissipation protecting system has the advantages that heat dissipation can be conducted on the shaft seal effectively, service life of a mechanical seal of a like pump is prolonged, the number of maintenance times is reduced, cooling water branches at the tail end are full of water, and stable operation of the system is guaranteed.
Description
Technical field
The present invention relates to centrifugal pump technical field, relate 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 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.
Summary of the invention
The present invention is intended to for the deficiency existing in background technique, and a kind of centrifugal pump seal water-cooling protective system is provided.
of the present inventioncentrifugal pump seal water-cooling protective 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 protective system of the present invention; 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.
