Description
[technical field]
The present invention relates to centrifugal multistage pump multiple centrifugal pump technical field, the vertical multi-stage of a kind of universal connection support from
Heart pump.
[background technology]
At present, vertical multi-stage centrifugal pump is quite varied, in recent years along with Chinese science and technology as the application of universal hydraulic
Developing rapidly, the demand of vertical centrifugal multistage pump multiple centrifugal pump is also constantly increasing.Traditional vertical multi-stage centrifugal pump, generally connects with motor
Connect employing electric machine support mode when being attached, increase, according to electric machine stand number and watt level because water pump progression increases power
Difference need the support of multiple specifications to mate, often because mould is many, model is many, thus to produce bring the biggest
Trouble, is difficult to carry out the production and processing of batch.And, because support is short, space is little, must be by electricity when dismantling and change mechanical seal
Machine is dismantled, fairly cumbersome, all brings a lot of inconvenience to maintenance and replacing mechanical seal.
[summary of the invention]
Present invention aim to solve above-mentioned deficiency and provide the vertical multi-stage of a kind of universal connection support from
Heart pump, solves that water pump support batch production processing model multi-mould is many and in operation, more mold exchange and frock waste time and energy and ask
Topic, decreases bracket mould and processing tool, facilitates storehouse management.
Design the vertical multi-stage centrifugal pump of a kind of universal connection support for achieving the above object, including water pump water inlet-outlet segment
1 and motor 9, described water pump water inlet-outlet segment 1 is internal is provided with impeller 2, stator 3 and pump shaft 13, and described water pump water inlet-outlet segment 1 is provided with
Sleeve 4, described sleeve 4 upper end connects pump cover 11, is provided with mechanical seal 5, described pump shaft between described pump shaft 13 and pump cover 11
Being connected by shaft coupling 6 between 13 with motor 9 output shaft, described pump cover 11 is provided with connection support 7, described connection support 7
Upper connection has counter flange 8, described counter flange 8 to be connected with motor 9, passes through transition between described connection support 7 and motor 9
Flange 8 conversion connects.
Described connection support 7 is set to hollow heightening type, and described shaft coupling 6 is located in connection support 7, described shaft coupling 6
Being reserved with withdrawal space cavity 10 between interior pump shaft 13 and motor 9 output shaft, described withdrawal space cavity 10 is not for dismantling
Carry out pump maintenance in the case of motor 9 and change mechanical seal 5.
Being provided with base plate 14 below described water pump water inlet-outlet segment 1, described base plate 14 connects pull bar 12, and described base plate 14 leads to
Cross pull bar 12 pump cover 11, sleeve 4, water pump water inlet-outlet segment 1 to be connected as one.
The present invention is compared with the existing technology, novel structure, simple, reasonable in design, by the connection of water pump and motor being propped up
A kind of universal type made by frame, thus water pump is in the case of progression increases power increase, it is not necessary to changes and connects support, only needs
Change counter flange to be connected easily with motor, the most both need not out multiple bracket mould model, and advantageously
In produce in batch machining and the trouble of inventory multiple gauges, solve water pump support batch production processing model multi-mould many with
And in operation, more mold exchange and frock waste time and energy problem, decrease bracket mould and processing tool, facilitate storehouse management；This
Outward, the present invention is by by connecting the amplification of internal stent space, when keeping in repair and change mechanical seal, it is not necessary to dismantles motor and props up
Frame, and only motor and water pump coupler need to be dismantled and can change mechanical seal easily, so that maintenance maintenance is convenient,
It is worthy of popularization.
[accompanying drawing explanation]
Fig. 1 is the structural representation of the present invention；
In figure: 1, water pump water inlet-outlet segment 2, impeller 3, stator 4, sleeve 5, mechanical seal 6, shaft coupling 7, connection
Frame 8, counter flange 9, motor 11, pump cover 12, pull bar 13, pump shaft 14, base plate.
[detailed description of the invention]
Below in conjunction with the accompanying drawings the present invention is made further explained below:
As shown in Figure 1, the present invention includes: water pump water inlet-outlet segment 1 and motor 9, and water pump water inlet-outlet segment 1 is internal is provided with impeller
2, stator 3 and pump shaft 13, water pump water inlet-outlet segment 1 is provided with sleeve 4, and sleeve 4 upper end connects has pump cover 11, pump shaft 13 to be provided with machine
Tool seals 5 and is connected to form sealing with pump cover 11, is connected, on pump cover 11 by shaft coupling 6 between pump shaft 13 with motor 9 output shaft
Being provided with connection support 7, connecting to connect on support 7 has counter flange 8, counter flange 8 to be connected with motor 9, connects support 7 and electricity
Being connected by counter flange 8 conversion between machine 9, be provided with base plate 14 below water pump water inlet-outlet segment 1, base plate 14 connects pull bar
