Technical Field
[0001] The utility model relates to the technical field of coupling protection equipment, in particular to a centrifugal pump coupling safety shield. Background Art
[0002] Couplings are typically used to connect driven equipment to transmit power and torque. During operation, couplings also operate at high speeds, necessitating physical isolation. The primary function of a coupling guard is to prevent high-speed coupling components from loosening and flying out, potentially posing a danger to personnel. It also prevents humans, animals, rain, and snow from disrupting normal operation.
[0003] The existing centrifugal pump coupling guard is a semicircular guard with open ends, which has a low safety factor and can easily cause objects to be entangled in the coupling, causing damage to people and equipment. When inspecting and maintaining the pump, it is also necessary to disassemble and install the coupling guard, which wastes time during the disassembly and installation process and is also cumbersome to operate. Various unreasonable factors bring hidden dangers to the normal operation of safe production. In addition, the existing guards are all fixed structures, and different couplings need to be equipped with guards of different sizes. Therefore, it is necessary to design a safety guard with a high safety factor, easy disassembly and high applicability. Utility Model Content
