A portable hydraulic dismantling device

Abstract

This utility model discloses a mobile hydraulic disassembly device, belonging to the technical field of disassembly tools. It includes a moving mechanism with a horizontally placed hydraulic cylinder. A bracket is fixed to the non-piston end of the hydraulic cylinder, and multiple threaded rods are detachably mounted on the bracket. Each threaded rod is threaded with a first nut. In this utility model, the piston end of the hydraulic cylinder is used to hold the motor pump shaft, while the threaded rods can pass through the mounting holes of the flange of a large water pump, and are threaded with the first nut after passing through. Thus, when the hydraulic cylinder is running, the piston end can push out the motor pump shaft, thereby achieving disassembly. After disassembling the motor pump shaft of a large water pump, some large water pump motor bearings are difficult to remove. In this case, this device can act as a puller, supporting the rear end of the bearing with three clamping plates, and then operating the hydraulic cylinder to align with the motor shaft and push out the bearing to be removed.

Description

Technical Field

[0001] This utility model belongs to the field of disassembly tool technology, and in particular relates to a hydraulic disassembly device that is easy to move. Background Technology

[0002] A water pump is a machine that transports or pressurizes liquids. It transfers the mechanical energy of a prime mover or other external energy to the liquid, increasing its energy. It is mainly used to transport liquids including water, oil, acids and alkalis, emulsions, suspensions, and liquid metals. It can also transport mixtures of liquids and gases, as well as liquids containing suspended solids. Technical parameters of water pump performance include flow rate, suction head, discharge head, shaft power, water power, and efficiency. Based on different working principles, they can be classified into positive displacement pumps, centrifugal pumps, etc. Positive displacement pumps transfer energy by utilizing changes in the volume of their working chamber; centrifugal pumps transfer energy by utilizing the interaction between rotating blades and water, and include centrifugal pumps, axial flow pumps, and mixed flow pumps.

[0003] When large water pumps are overhauled, the motor shaft may become firmly stuck in the inner ring of the bearing due to prolonged disassembly, making it very difficult to remove. Currently, a great deal of force is required to knock the pump shaft out. During maintenance, the motor bearings of some large water pumps are difficult to remove.

[0004] Therefore, this utility model proposes a hydraulic disassembly device that is easy to move. Utility Model Content
