At present, most domestic vertical diagonal flow pump product does not arrange thrust bearing part, bears residual axial force by motor, and mostly adopts packing seal to carry out shaft seal, reduces reliability and the environmental requirement of product; The Spit Section of common vertical diagonal flow pump is cast structure, and weight is large and whole part is a kind of material, and manufacture cost is higher; And box coupling adopts completely circular structure, be easily engaged in pump shaft installation and unloading process, occur the problem of dismounting inconvenience.
Summary of the invention
For above-mentioned existing problems, the purpose of this utility model is to provide that a kind of reliability is high, structure is simple, cost is low, be easy to the vertical diagonal flow pump product of installing/dismounting, to meet user's high reliability and environmental requirement.
The purpose of this utility model is realized by following technical proposals: propose a kind of vertical diagonal flow pump, bearing part is arranged on Spit Section, upper axle and lower shaft adopt box coupling to be connected, suction casing is positioned at below the pump housing, bearing housing is provided with the angular contact ball bearing of a pair back-to-back placement, angular contact ball bearing is fixedly connected with bearing housing.
The bend pipe that spues of described Spit Section is formed by the welding of multistage pipe crimping, and Spit Section base plate is carbon steel base plate, and the overcurrent position built-up welding on the base plate of Spit Section has stainless steel lining.
The overcurrent position of the described bend pipe that spues is formed by the welding of stainless steel pipe crimping, and non-overcurrent position is formed by the welding of carbon steel pipe crimping.
Described box coupling is split type box coupling, and split type box coupling is made up of the sleeve of two semicircle shapes.
Be provided with mechanical seal below described bearing part, below mechanical seal, be provided with sliding bearing.
Vertical diagonal flow pump described in the utility model compared with prior art, has the significant advantage of following several respects:
1. adopt the thrust bearing part of angular contact ball bearing as pump of a pair back-to-back setting, improve the reliability of unit, below bearing part, be configured with mechanical seal simultaneously, instead of packing seal conventional in existing diagonal pumps, greatly reduce the vent flow of medium, improve the application area of environmental requirement and product.
2. Spit Section is welded structure, avoids casting defect, and component quality easily ensures, overcurrent position adopts stainless steel, non-overcurrent position employing carbon steel material simultaneously, greatly reduces cost of material.
3. adopt split type box coupling to connect upper axle and lower shaft, avoid spindle parts, in installation and unloading process, scuffing occurs, greatly facilitate the I&M of pump, reduce maintenance cost.
4. mechanical seal place is provided with sliding support, reduces the beat of pump shaft in sealing place, improves the working life of mechanical seal.
