Cable fixing device of submersible pump

Abstract

The invention discloses a cable fixing device of a submersible pump, which comprises a hanging piece and a cable fixing component, wherein the hanging piece is installed on a shaft wall and is connected with a wire rope for lifting the submersible pump, and a rope strainer and a rope shackle are arranged on the wire rope; and the cable fixing component comprises a cable fixing seat, an elastic coating piece coated on the cable fixing seat, a rigid strip for fixing the elastic coating piece, and a fixing piece for positioning the cable fixing seat on the wire rope. The invention solves the problem of cable fixing of the submersible pump in a shaft type installation system and ensures that the cables are kept stable in the water flow free from tension and pressure disturbance, have no torsion, small swing and no damage, are not bonded mutually and are safe and reliable under the condition that the pump is installed and maintained conveniently and quickly.

Description

technical field [0001] The invention relates to a cable fixing device, in particular to a cable fixing device for a submersible pump. Background technique [0002] The cables configured by the submersible axial flow pump are located in the area where the pump outputs pressure water flow. In this area, the water flow not only has a large flow rate, but also has rotational movement, and the flow state is complex, which greatly disturbs the cables. If it cannot be fixed correctly, the cable will twist and swing, and in severe cases, it will be broken and cracked, causing leakage and water ingress in the motor, affecting the normal and safe operation of the submersible axial flow pump, and causing safety accidents; It is also necessary to consider the convenience and speed of pump installation and maintenance, and give full play to the advantages of submersible axial flow pumps. Such as a kind of submersible pump cable protection device disclosed in the invention patent applica...

[0002] The cables configured by the submersible axial flow pump are located in the area where the pump outputs pressure water flow. In this area, the water flow not only has a large flow rate, but also has rotational movement, and the flow state is complex, which greatly disturbs the cables. If it cannot be fixed correctly, the cable will twist and swing, and in severe cases, it will be broken and cracked, causing leakage and water ingress in the motor, affecting the normal and safe operation of the submersible axial flow pump, and causing safety accidents; It is also necessary to consider the convenience and speed of pump installation and maintenance, and give full play to the advantages of submersible axial flow pumps

Such as a kind of submersible pump cable protection device disclosed in the invention patent application specification CN1904388A published by the State Intellectual Property Office of China on January 31, 2007, the water pump is hoisted by steel pipes, and the cable is positioned with channel steel and sliders. , and then use protective rubber, pressure plate and bolts to wrap the cables together, and finally fix them on the steel pipe. This kind of device has many parts and complex structure. The weight is greatly increased, which is not convenient for installation and maintenance; if the cables are wrapped together and then clamped with a pressure plate, if things go on like this, the cable insulation will age and crack, causing the main cable and the control cable to stick together, causing a short circuit and accidents
