Description
Technical field
The utility model relates to a kind of pumping unit, is specifically related to a kind of scale pump.
Background technique
Existing pump industry long-axis vertical dirty pump of mixing comes transport process city, power plant waste water, and long-axis vertical mixes dirty pump structure as shown in Figure 1, and long-axis vertical dirty pump of mixing exists following shortcoming in use:
1. the bearing in the pump housing adopts water lubriucated bearing 107, because bearing is generally with teflon or polyethers ether copper etc., its expansion coefficient is larger, water lubricating pilot bearings 107 and axle 108 fitting surface produce more heat transfer when running, easily axle 108 locking, thus water lubriucated bearing 107 and axle 108 are scrapped, the working life of water lubriucated bearing 107 is 1-3 month, causes the pump life-span short;
2. adopt between each axle 108 in the pump housing and breathe out not 104 connections, although not 104 centerings connected are good in Kazakhstan, when using, there is the caducous shortcoming of appearance;
3. because the pump housing is long, just must dismantle from guide shaft seat 115 when pump will change axle or bearing, and then tear guide bearing lid 114, impeller nut 113, pump cover 112 and impeller 111 successively open, pump integral demounting could need be safeguarded when the pump housing is safeguarded, and it is longer to change time of bearing, cause the pump housing safeguard needed for chronic;
4. the connection between connecting tube 105 and guide bearing support 106 belongs to interior rim of the mouth, ensure concentricity between the two, parallelism, perpendicularity, and cause the processed complex of connecting tube 105, work efficiency is low;
5. long-axis vertical is mixed when dirty pump uses and need be added clean cooling water in pillar 103, and cooling water top to bottm enters below sky finally by impeller 111 and leads 112 and be transferred away with medium, and water resource waste is serious;
6. two dish bearings only used by bearing on using, and all the other are water lubriucated bearing, and because water lubriucated bearing very easily weares and teares, thus cause axle 108 to carry with water lubricating pilot bearings 107 bias, precision reduces, and vibrate bigger than normal during pump operation, the pump life-span greatly reduces;
7. what pump adopted is packing seal, and sealing effect is poor, forms dynamic cooperation during pump operation between axle 108 with filler 102, and filler wearing and tearing cause leakage.
Model utility content
The purpose of this utility model is to provide a kind of scale pump, and pump operation is reliable steadily, life, and pump housing processing and assembling cost and maintenance cost are all very low.
For achieving the above object, the technological scheme that an embodiment of the present utility model takes is:
Comprise impeller, impeller eye connects pump cover, impeller outlet auxiliary connection impeller, and sub-propeller is socketed deflector outward, and the sub-propeller the other end connects lower shaft, and deflector is connected with pillar by contiguous block; Outside framework oil seal is equipped with between deflector and lower shaft, between contiguous block and lower shaft; Lower shaft connects upper axle by multiple jack shaft; Lower shaft, jack shaft and upper outer shaft sleeve connect multiple pillar, and pillar overcoat is taken in succession, and lower shaft, jack shaft and upper axle support by bearing, and be stationary fit between bearing and axle, bearing is positioned at bearing support, male-female between bearing support and connecting tube; Upper axle upper end is connected with power system, and power system is driven by motor; Connecting tube and power system are all located on pump holder.
Preferably, upper axle upper end joins device, Electricity Federation device and pivot pin with axle equal between power system, between lower shaft with jack shaft, between jack shaft, between jack shaft with upper axle by pump and is connected.
Preferably, bearing is equipped with outside framework oil seal and 0 type circle static seal; Sub-propeller motive sealing is added above impeller.
Preferably, pump cover connects filter screen.
The beneficial effect that this scale pump produces is:
1. pump connection device, Electricity Federation device, pivot pin have connected carry-over moment between axle and axle and damping effect and automatically coaxality problem between adjusting axle and axle;
2. adopt convex-concave to combine between connecting tube and bearing support, form that honeycomb duct makes the well flowing from below to up of institute's fed sheet of a media, connecting tube adopts boss also well to solve processing problems;
3. be provided with outside framework oil seal between bearing and axle, bearing support, bearing gland, between bearing and outside framework oil seal, form confined space, define good oil sealing space after filling it up with grease and the bearing of high speed operation is lubricated; Its grease is cooled by self fed sheet of a media, need not additional cooling water.
4. between bearing and axle for stationary fit, there is not friction, just not there are wearing and tearing, make axle and bearing remain highi degree of accuracy cooperation and then ensure that traveling comfort;
5. impeller, pump cover, choma, sky are led and are defined a seal space, impeller the moment transmitted to axle after at the uniform velocity rotate, and power is passed to carried medium, and liquid centrifugal force and to lifting force, liquid just prolongs space that pillar and connecting tube bearing support formed to pump discharge flowing and realizes pumping the object of liquid medium;
6. each bearing position all have employed outside framework oil seal and adds 0 type circle static seal in the pump housing, and installed sub-propeller motive sealing above impeller additional, and between spatial guide blade, gap control is at 0.3-0.5mm, sealing effect is better.
