Based on experience, what type of coupling is generally used for this type of pump?
Thread Content
As the question goes, it rained in the morning. In the afternoon, I went to the construction site to dismantle the protective cover and reveal the answer: lol
According to experience, this kind of pump generally uses elastic coupling or gear coupling. Among them, elastic couplings are suitable for situations where the load changes greatly, while gear couplings are suitable for situations where the speed and load are relatively stable. .
hint: Mechanical couplings are divided into two categories: rigid and flexible according to the "Coupling Classification" CB/T 12458-2017. Rigid couplings include flanges and clamps. Flexible couplings include sliders, gears, roller chains, universal cross shafts, tire types, plum blossoms, elastic pins, diaphragms, elastic sleeve pins, snake springs, V-belt pulleys, steel sand type safety couplings and other common types.
Thank you very much for the tips! Based on the information you provided, this pump may have a gear coupling type in a flexible coupling. Because the gear coupling is suitable for bearing a certain load and speed, and has good shock absorption and buffering effects. At the same time, the structure of the gear coupling is relatively simple and easy to repair and replace. Of course, the specific coupling to be used needs to be further judged based on the actual situation and the working characteristics of the pump. .
It should be a coupling with plum blossom petals. Forgot its name.
Thank you for your participation. I did not disassemble it because of the protective cover. According to my observation, this is a three-claw coupling for pumps, but the classification is not clearly stated. It should be a flexible slider coupling.
Such water pumps rarely use elastic pins. They are only used in large pumps. Small pumps generally use the three-claw issued by the original poster.
