Abstract
The utility model is a kind of Super Long-axles Under Water Pumps pump head activity stationary support bottom, it is characterized in that the pump inlet pipe 4 of Super Long-axles Under Water Pumps 1 is fixed on pump diffuser 2 by bolt 3, dunnage 5 is fixed on pump inlet pipe 4 by bolt 7, support plinth 8 is coordinated by fitting surface 6 with dunnage 5, be provided with guiding gutter 10 between dunnage 5 and support plinth 8, described dunnage 5 is provided with the dunnage guiding conical surface 11.Advantage: during installation, dunnage 5 freely slides in support plinth 8 by the dunnage guiding conical surface 11 and the base guide conical surface 9, and carry out activity cooperation by fitting surface 6, play radial fixation, thus secure long shaft submerged pump pump head bottom, eliminate the distortion of pump shaft, ensure that the running accuracy of pump, alleviate the vibration of pump, thus improve the working life of pump; And structure is simple, reliable, to research safety, reliable, long lifetime Super Long-axles Under Water Pumps is significant.
Description
Technical field
The utility model relates to a kind of Super Long-axles Under Water Pumps pump head activity stationary support bottom, belong to Under Water Pumps technical field.
Background technique
Under Water Pumps is immersed in the middle of transported medium by the flow passage components such as impeller, the pump housing, and the driving mechanisms such as motor are positioned at the vertical pump of a kind of special shape of top, basis, in the pump series products that China uses, occupies sizable ratio.Have vertical installation compared with horizontal pump, floor space is few, can reduce pump house area, and reduce capital construction cost, the impeller of Under Water Pumps is immersed in the medium of conveying, need not pump priming during startup, can carry out the advantages such as centralized automatic control; There is the advantage of Electrical Safety compared with submersible pump; Compared with self-priming pump, can use the working condition that the degree of depth under liquid is greater than 8 meters, therefore Under Water Pumps is widely used in the industries such as metallurgy, petrochemical industry, power plant and environmental protection.
Super Long-axles Under Water Pumps installation method is arranged on base layer by pump base plate, pump head is suspended on pump base plate by connecting tube, pump head is generally greater than 8 meters to the distance of pump base plate and is less than 28 meters, Here it is refers to the degree of depth under the liquid of Super Long-axles Under Water Pumps, because pump head is suspended on pump base plate, pump head is made to be in overlength cantilever state like this, pump head is built with an impeller or multiple impeller simultaneously, vane rotary produces certain centrifugal force, centrifugal force can cause the pump head end of cantilever to produce larger swing, pump shaft is caused to be out of shape, distortion can make the guide bearing of pump supports main shaft produce wearing and tearing, wearing and tearing make the gap between guide bearing and axle sleeve strengthen, thus cause the vibration of pump, substantially reduce the working life of pump, this is long shaft submerged pump life-span of current common form short main cause.
The simple and effective Super Long-axles Under Water Pumps pump head that prevents produces the method swung, and fixes long shaft submerged pump pump head bottom exactly, makes it under any operating mode, can not produce and radially wobble, thus ensure that the running accuracy of pump, eliminate the distortion of pump shaft, alleviate the vibration of pump, improve the working life of pump.
Summary of the invention
