Gas-liquid linked dismounting device of fan impellers

Abstract

The invention relates to a gas-liquid linked dismounting device of fan impellers, mainly comprising a stand, a hydraulic system, a pneumatic system, an electrical control system, a dismounting operation device, a lifting table and a rotating platform. The gas-liquid linked dismounting device is characterized in that impeller shaft sleeves are clamped by adopting the hydraulic system, a motor shaft is impacted by the pneumatic system for the gas-liquid linked dismounting of the fan impellers, a jaw part is provided with teeth and is locally quenched, the lifting table adopts a scissors fork type structure and has a high lifting speed and a low lifting speed, wherein the low lifting speed is used for dismounting alignment. When the impellers at both ends of a fan are dismounted, the fan is placed on the platform, and then the two impellers can be rapidly dismounted by utilizing the rotation and the lifting of the platform; and a clamp head is pushed to clamp the impeller shaft sleeves by an oil cylinder, an impacting mechanism carries out flexible impacting and loosening on the motor shaft, an uploading air cylinder generates static thrust for the impact mechanism and applies the static thrust to the motor shaft, and the motor shaft is pushed out of the impeller shaft sleeve under the actions of a dynamic load and a static load. The invention can prevent the fan impellers, the impeller shaft sleeves and the motor shaft from being damaged when the fan is dismounted, thereby greatly improving a dismounting effect.

Description

technical field The invention relates to fan equipment, in particular to a gas-liquid linkage dismantling device for a fan impeller applied to the disassembly of a centrifugal fan impeller. Background technique Existing centrifugal fans all include impellers. When the fan is working, the impellers are easily dirty, which affects the performance of the centrifugal fan, and is also easy to damage the impellers. The impellers need to be removed regularly for cleaning and maintenance. In the maintenance of centrifugal fan, the disassembly of centrifugal fan impeller is an important maintenance work. Due to the special structure of the centrifugal fan impeller and its shaft sleeve, Rama cannot be used to disassemble the impeller. At the same time, due to the limited disassembly space of the impeller, it takes time to disassemble the impeller with a simple fixture such as a clamp device, and the disassembly efficiency is low. The manual disassembly method is to knock the impelle...

Due to the special structure of the centrifugal fan impeller and its shaft sleeve, Rama cannot be used to disassemble the impeller

At the same time, due to the limited disassembly space of the impeller, it takes time to disassemble the impeller with a simple fixture such as a clamp device, and the disassembly efficiency is low. The manual disassembly method is to knock the impeller shaft sleeve from one side of the impeller with an iron rod or hammer , it is time-consuming and laborious, and it is easy to cause damage to the fan impeller and motor shaft, and even cause the entire fan to be scrapped. Therefore, there has been no efficient impeller removal device at present.

For the rusty centrifugal fan at the junction of the impeller shaft sleeve and the motor shaft, there is no set of effective disassembly methods and disassembly tools.
