[0006] 3. Ignoring the force of tightening the screw port, as far as the cable fixing device itself is concerned, because the water pump stops when the deflation condition is not good, the liquid in the pipeline will flow back and the impeller will reverse, thereby generating upward water thrust. Under the action of the force, the unit has a tendency to lift upwards. When the force is greater than the gravity of the water pump, the machine will be lifted. The original cable fixing method has no protective measures for this, which is undoubtedly unreasonable

Embodiment Construction

[0020] see image 3 , straight seam electric welded steel pipe is divided into two sections, steel pipe A and 4 steel pipe B, connected by flange so as to avoid installation inconvenience caused by improper height of steel pipe, steel pipe A and 4 steel pipe B are fixed by bolts; water pump lifting frame 6 Welding one section is fixed with steel pipe 8 larger than cable steel pipe B4 diameter five to eight millimeters, the lower end of steel pipe B4 is directly inserted in the pipe of fixed steel pipe 8, so just finished fixing below conveniently. Cable wire 13 is wrapped up with protective rubber 9, and it is pressed with steel pipe as Figure 4 Arranged in the same way, the cables 13 are fixed between the pressure plates 11, the pressure plates 11 (two, one welded on the steel pipe) and the steel pipe collar 10 are fixed on the steel pipe B with bolts 5, and a group is fixed every 300mm or so, so that Just finished the fixing of cable and steel pipe. The rotatable steel pi...

Abstract

An improved submersible pump cable protector comprises steel pipes, a slider, channel steel and a cable-fixing device. A rotating steel pipe is set on the flange on top of the shaft and it is connected with the channel steel. The slider is mounted on the channel steel and the bottom of the slider is connected with a steel pipe A (3). Several sets of the cable-fixing device are mounted on a steel pipe B and the lower end of the steel pipe B is inserted in the steel pipe (8) for fixing. The lower end of the steel pipe (8) is welded on the lift frame of the water pump.

Description

[technical field] [0001] The invention relates to the technical field of water conservancy machinery, in particular to a cable protection device and an anti-lifting device installed in submersible axial flow and mixed flow pumps. [Background technique] [0002] Such as figure 1 As shown, the existing cable fixing method. The fixing principle is mainly as follows: firstly, pass the steel wire rope through the lifting frame of the pump, and clamp it with a wire rope clamp; then, as shown in Figure 2, fix the cable and the steel wire rope in the pressure plate at the same time, and press the pressure plate with bolts. Carry out this kind of fixing on the cable at an appropriate distance; when it reaches the tail, pass the wire rope through the turnbuckle, fix it with a wire rope clamp, pass the other end of the turnbuckle through the eye screw, and then tighten the turnbuckle. In this way, the fixing of the cable is completed. [0003] Disadvantages of this cable fixing meth...
