Abstract
The invention discloses a novel high-performance double-bearing vortex pump. With the adoption of methods of empirical design and numerical simulation of model test data, optimization design of the vortex pump is realized, the optimization of impeller backlash and a double-bearing structural design of an impeller shaft are obtained, and the serious problems that various domestic vortex pumps are complicated in structure, the overall dimensions of the pumps are increased, and the transmission accuracy cannot be ensured since the vortex pumps adopt single bearing suspension separated structures at present are solved. The pump is used for the fields of lorries, ships, large-sized diggers, railway locomotives, coal and oil exploitation machines and the like extensively, and has a very high promotional value.
Description
Technical field
The present invention relates to a kind of
The novel dual-supporting peripheral pump of high-performance, particularly relate to
Fields such as truck, boats and ships, large excavator, railway locomotive, coal and petroleum production machinery
Background technique
At present, developed countries has the research of this respect, but because blockade on new techniques causes this technology to introduce.Domestic research, production
The novel dual-supporting peripheral pump of high-performanceAll do not satisfy
TruckUsage requirement to peripheral pump.At home "
The novel dual-supporting peripheral pump of high-performance" can't realize production domesticization.
Develop the novel dual-supporting peripheral pump of high-performance that performance satisfies fields such as truck, boats and ships, large excavator, railway locomotive, coal and petroleum production machinery as early as possible, be an imperative and ten minutes urgent task.
Summary of the invention
(1) on seal form, adopts Inner bag skeleton rotary shaft lip seal, the limitation of the mechanical seal mode that the breakthrough existing product adopts has been simplified sealing configuration, has satisfied the requirement of this product miniaturization.Its material selection F-G has high-and low-temperature resistance and good anti-corrosion capacity, has improved sealing reliability.
(2) on the optimal design of impeller,Set up both sides both shoulders formula blade wheel structure, broken through the impeller sideshake and adjusted difficult constraint, eliminated flow pulsation, moved jiggly problem.Thereby guaranteed the axial clearance minimum of impeller and the pump housing and pump cover.
(3) on the supporting structure mode of peripheral pump, adopt double supporting structure,Avoid impeller shaft bending deflection at work effectively, fundamentally guaranteed the functional reliability of product, improved the shock resistance of product.
Description of drawings
The novel dual-supporting peripheral pump of high-performance working principle: the novel dual-supporting peripheral pump of high-performanceBe made up of direct current motor and pump head, pump head mainly contains the pump housing, pump cover and impeller, and the cavity between impeller and the pump housing and the pump cover constitutes runner.During the rotation of motor drives impeller, cause the motion of all making circumferencial direction in the impeller with the interior liquid of runner, thereby produce centrifugal force.Because the peripheral velocity of the liquid in the impeller is greater than the peripheral velocity of liquid in the runner, namely the centrifugal force of liquid forms the circulatory motion of similar vortex greater than the centrifugal force of the liquid that moves in the runner in the impeller.
In the Figure of description, Fig. 1 is the outline drawing of the novel dual-supporting peripheral pump of high-performance.Among Fig. 1: the 1-hollow bolt; The 2-pipe joint; The 3-pump cover; The 4-motor; The 5-pump housing.
