Description

Technical Field

[0001] The utility model belongs to the technical field of shielded pump assembly and relates to shielding sleeve assembly equipment. Background Art

[0002] The shielded pump connects the pump and the motor together. The motor rotor and the pump impeller are fixed on the same shaft. The shielding sleeve is used to separate the motor rotor and the stator. The rotor runs in the medium being transported, and its power is transmitted to the rotor through the stator magnetic field. The shielding sleeve is a key component in the shielded pump. The precision requirements for its processing and assembly are very high, which also brings inconvenience to its disassembly and assembly.

[0003] Chinese invention patent application CN 109333442 A (application publication date: 2019.02.15) discloses a disassembly device for a shielding sleeve assembly, including a frame, a power mechanism arranged on the frame, a linkage mechanism driven by the power mechanism, and side claws and prying claws driven by a connecting mechanism, wherein the connecting mechanism is used to drive the side claws and prying claws to open or close, so that the side claws and prying claws cooperate with the pump cover on the shielding sleeve assembly, and the connecting mechanism is used to drive the prying claws to cooperate, so that the prying claws pry the pump cover to separate the pump cover from the shielding sleeve. Under the action of power, the shielding sleeve and the pump cover can be separated smoothly and quickly through the cooperation of the side claws and prying claws on the disassembly device. Although the disassembly device can disassemble the shielding sleeve, its structure is relatively complicated and not very convenient to use. Utility Model Content
