The submerged pump comprises the motor, the pump shaft and a supporting tube assembly, the pump shaft is positioned in the supporting tube assembly, a bearing block shaft is arranged at the upper end of the pump shaft, and is detachably connected with the pump shaft, a motor coupler and a pump coupler are arranged between the motor and the pump shaft, the bearing block shaft and the pump coupler are formed integrally, and the motor coupler is connected with a motor shaft. The connecting structure of the pump shaft and the motor of the submerged pump adopts the mode, maintenance load is reduced, and the service efficiency of the pump is improved.
Description
Technical field
The present invention relates to Under Water Pumps, particularly relate to a kind of pump shaft of Under Water Pumps and the linkage structure of motor.
Background technique
The medium of automobile, household electrical appliances, the discharge of silicon steel cold-reduced sheet pickling conveying spent acid is high temperature concentrated hydrochloric acid, sulfuric acid, hydrofluoric acid etc., corrosivity is extremely strong, temperature higher (80 DEG C ~ 100 DEG C), most metal and alloy all can not as the use materials of pump, and specific alloy can use but price spy is expensive, so must use nonmetal, but not metal corrosion-resisting is very strong, but physical property is unstable, easily expands with heat and contract with cold, very easily cause the leakage at pump seal place.Existing Under Water Pumps comprises motor, pump shaft, support tube assembly, outlet pipe, the pump housing, impeller and slips through the net, pump shaft is positioned at support tube assembly, the side of support tube assembly has outlet pipe, the lower end of pump shaft has impeller and the pump housing, the bottom of outlet pipe has the bend pipe be communicated with support tube assembly, and the below of the pump housing has slips through the net.Such structure, the workload of maintenance when Under Water Pumps damages is large, and engineering time is long.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of pump shaft of Under Water Pumps and the linkage structure of motor, and the use of the pump shaft of this kind of Under Water Pumps and the linkage structure of motor can reduce maintenance load, improves the utilization efficiency of pump.
Solve this technical problem, technological scheme of the present invention is: a kind of pump shaft of Under Water Pumps and the linkage structure of motor, Under Water Pumps comprises motor, pump shaft and support tube assembly, pump shaft is positioned at support tube assembly, the upper end of described pump shaft is provided with bearing support axle, and described bearing support axle and pump shaft removably connect, and is provided with motor coupler and pump coupling between described motor and pump shaft, described bearing support axle and pump coupling form one, and described motor coupler is connected with motor shaft.
The upper end of described pump shaft is provided with labyrinth seal portion.
The pump shaft of Under Water Pumps of the present invention and the linkage structure of motor are adopted in such a way, decrease maintenance load, improve the utilization efficiency of pump.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, high temp. salt acid Under Water Pumps of the present invention is described in further detail;
Fig. 1 is pump structure schematic diagram under high temp. salt acid solution of the present invention;
In FIG, 1, motor; 2, rolling bearing; 3, bearing support; 4, pump shaft; 5, outlet pipe; 6, sliding bearing; 7, impeller; 8, bend pipe; 9, slip through the net; 10, liquid lower link bolt; 11, the pump housing; 12, support tube assembly; 13, bearing support axle; 14, pump coupling; 15, motor coupler.
Embodiment
As shown in Figure 1, high temp. salt acid Under Water Pumps comprises motor 1, motor coupler 15, pump coupling 14, bearing support axle 13, pump shaft 4, support tube assembly 12, outlet pipe 5, the pump housing 11, impeller 7 and slip through the net 9, pump shaft 4 is positioned at support tube assembly 12, the side of support tube assembly 12 has outlet pipe 5, upper end and the bearing support axle 13 of pump shaft 4 removably connect, the upper end of pump shaft is provided with labyrinth seal portion, the lower end of pump shaft 4 has impeller 7 and the pump housing 11, the top of pump shaft 4 has bearing support 3 and rolling bearing 2, rolling bearing 2 is positioned at bearing support 3, sliding bearing 6 is installed in the bottom of pump shaft 4, the bottom of outlet pipe 5 has the bend pipe 8 be communicated with support tube assembly 12, the below of the pump housing 11 has slips through the net 9.Liquid lower link bolt 10 adopts the plastic technique of stainless steel, and nut also uses stainless steel nut plastic, guarantees that nuts and bolt bolt not only has good intensity but also can not by dielectric corrosion.
Pump drive shaft has upper and lower two independent sector bearing support axles 13 and pump shaft 4 to form, top and bearing support and bearing assemble integral, the pump shaft 4 of lower part for ladle mould after and sliding bearing 6 and impeller 7 assemble rear medium contact.Such structure can be provided convenience for during maintenance, need not pull down bearing and bearing support axle when keeping in repair, and only need place under repair to pump shaft or change and then can.Design bearing adopts rolling bearing and sliding bearing to be combined, and liquid top is divided into rolling bearing, and liquid bottom is divided into sliding bearing, bear axis and radial force, and sliding bearing material is silicon carbide, only bears radial force, do not bear axial force, there is the performance of silicon carbide anticorrosive wear-resistant simultaneously.Because pump shaft is longer, this spline structure can ensure that pump operation is stablized, and noise is low, shakes little, long service life.
