The deficiency of traditional vertical centrifugal pump is, at normal temperature or under less than 120 ℃ of temperature, can satisfy usage requirement.But under 350 ℃ to 500 ℃ high temperature condition, the use of traditional vertical centrifugal pump is restricted: 1. the bearing under the conventional construction, comprise rolling bearing and sliding bearing, at high temperature the bearing play diminishes, and the little meeting of rolling play of rolling bearing causes the rolling bearing sharp wear; And the little sharp wear that not only can cause in the gap of sliding bearing also might make the rotatingshaft newspaper dead; 2. in the high temperature media environment, the flushing of the sliding bearing of traditional vertical centrifugal pump is lubricated also can not to be realized because the flushing Lubricants is improper; 3. the axle design that can extend of traditional vertical centrifugal pump, but under the high temperature condition, extension shaft can produce very large deformation, making the friction aggravation, and vibration and noise significantly increase, the shortening in working life of pump; 4. traditional sealing means is difficult to the sealing under the realization high temperature condition.
Summary of the invention
The purpose of this invention is to provide a kind of high temp, vertical centrifugal pump, make the traditional vertical centrifugal pump under the prerequisite that does not change cantilever structure, serviceability temperature is increased to below 500 ℃ from about 100 ℃.
Technological scheme of the present invention is: high temp, vertical centrifugal pump, by the pump jar, the pump housing, impeller, axle, support tube, bearing bracket stand, the motor frame, bearing and sealing component are formed, pump jar and upper plate, the pump housing and support tube, bearing bracket stand, the motor frame connects successively, the tip of the axis and impeller link, the output shaft that passes the motor on support tube and bearing bracket stand and the motor frame successively connects, its structure is that the described pump housing is the hydraulic model that the integral ring-shaped extrusion formula pump housing combines with prismatic blade formula impeller and constitutes, axle is a multidiameter shaft, the stage casing of axle is positioned on the shaft part of support tube is equipped with the effect ring, the effect ring is the circle shell-like, effect ring external peripheral surface has spiral helicine groove, Hand of spiral is to make the pressure that generation is directed downwards in the support tube after the rotation of effect ring, the lower end and the pump cover of support tube are connected as a single entity, be pump cover be again the lower shoe of support tube.
High temp, vertical centrifugal pump of the present invention, its structure is that the sliding bearing of axle adopts the high temperature sliding bearing and cancels sliding bearing lubricating system in the conventional construction, the rolling bearing of axle adopts the high temperature rolling bearing, and the bearing bracket stand of rolling bearing is provided with the cooling system that is made of cooling sap cavity and intake-outlet.
High temp, vertical centrifugal pump of the present invention, its structure are that described axle is adjustable axle, are respectively equipped with the screw thread that matches with locking nut at the two ends of axle, by the adjusting of adjusting lock nut's realization to the impeller clearance.
Characteristics of the present invention are:
One, pump structure is at the high temperature media specialized designs, and is simple and practical, is suitable for high temperature media and uses; Two, use the high temperature rolling bearing also with cooling liquid cooling bearing frame and employing high temperature sliding bearing, reduced the wearing and tearing of high temperature lower bearing, guaranteed the working life of bearing; Three, the effect ring is set in the support tube, makes the pressure that generation is directed downwards in the support tube, can further avoid high temperature media to external leakage; Four, adopt adjustable axle, help adjusting the gap between the pump housing and impeller blade, improve hydraulic efficiency, behind blade wear, also can readjust the gap simultaneously, make hydraulic performance need not change parts and just can recover, improve working life.
