Abstract
The invention relates to a novel cooling device for a high-temperature pump. The novel cooling device for high-temperature pump comprises a water inlet, cooling grooves, stop plates, a water outlet, a baseplate, threaded holes, threads and the like. The novel cooling device for the high-temperature pump is characterized in that a water cooling manner is adopted. When the high-temperature pump works, a high-temperature medium enters a pump inlet and reaches to a pump outlet via an impeller, heat is transferred to a mechanical seal and a bearing via a rotating shaft, and the cooling device is capable of cooling the mechanical seal and the bearing. The novel cooling device for high-temperature pump ensures the high-temperature pump to operate continuously in a long time without the bearing and the mechanical seal and has the advantages of low cost, no cooling pipeline, convenience in maintenance and transportation, no expensive cooling water, simple structure, small size, safety, reliability, simplicity in manufacturing and easiness in wide-range popularization.
Description
Affiliated technical field
The present invention relates to new pump High-temperature cooling device.
Background technique
High temperature pump is widely used in the every field of the national defence such as chemical industry, electric power, medicine food, metallurgical mine, textile printing and dyeing, the nuclear industry energy and national economy.
Generally, high temperature pump passes through carried high temperature media, axle and temperature is passed to Seal cage and bearing bore by the parts that are connected with the pump housing, because the operating temperature General Requirements of bearing and mechanical seal is below 100 degree, exceeding this temperature just need to cool by external means, guarantee bearing and mechanical seal are normally worked at a relatively low temperature, common way is that to adopt constituent to force cooling, but most of this method makes whole system complex structure, volume large and waste valuable water resources.
Summary of the invention
The object of the invention is for above problem, propose a kind of new type high temperature pump refrigerating device that can overcome above problem.In order to achieve the above object, design proposal of the present invention is as follows:
New pump High-temperature cooling device, it mainly comprises the parts such as water intake, cooling bath, baffle plate, water outlet, base plate, tapped hole, screw thread.Its working principle be high-temp liquid from pump housing import by impeller to pump discharge, the connected body part that connects the pump housing and Seal cage (or bearing bore) attenuates, and has reduced on the one hand the heat of high-temp liquid to mechanical seal and bearing transmission; On the other hand, it is large that the relative surface area contacting with air becomes, this is more conducive to moving air and attenuates and take away heat from connected body part, reduce the transmission of high temperature media to mechanical seal and bearing heat, simultaneously, cooling water is entered to enter cooling bath from cooling vent and is streamed baffle plate and flow out from coolant outlet, and the heat of taking away thus most further reduces bearing and mechanical seal cavity temperature, thereby has ensured that bearing and mechanical seal can long-time continuous runnings.
The present invention is a kind of high temperature pump cooling unit of new structure, adopts Green Water cooling system, and simple in structure, volume is little, and cost is low, easy to use.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the present invention is further illustrated:
Fig. 1 is structural drawing of the present invention.
As shown in the figure, in figure: water intake 1, cooling bath 2, baffle plate 3, water outlet 4, base plate 5, tapped hole 6, screw thread 7.
Embodiment
Have shown in Fig. 1, new type high temperature pump refrigerating device of the present invention, mainly comprises the parts such as water intake 1, cooling bath 2, baffle plate 3, water outlet 4, base plate 5, tapped hole 6, screw thread 7.Its notable feature is to have adopted water-cooling pattern.When the running of this new type high temperature pump, high temperature media from pump inlet by impeller to pump discharge, heat is by axial rotary mechanical seal and bearing transmission, this cooling unit can play cooling to mechanical seal and bearing.Ensured this high temperature pump do not need bearing and mechanical seal just can long-time continuous the feature of running.
Claims (2)
1. new pump High-temperature cooling device, mainly comprises the parts such as water intake 1, cooling bath 2, baffle plate 3, water outlet 4, base plate 5, tapped hole 6, screw thread 7.Its notable feature is to have adopted water-cooling pattern.When the running of this new type high temperature pump, high temperature media from pump inlet by impeller to pump discharge, heat is by axial rotary mechanical seal and bearing transmission, this cooling unit can play cooling to mechanical seal and bearing.Ensured this high temperature pump do not need bearing and mechanical seal just can long-time continuous the feature of running.
