AI Technical Summary
The motor shaft and pump body shaft of existing high-temperature pumps are directly connected by a coupling, which makes the key side or keyway edge prone to plastic deformation, wear or even crushing under heavy load and high temperature and pressure conditions. The risk of damage is exacerbated, especially when the load is impacted or fluctuates.
The high-temperature pump motor heat insulation connection seat, which uses ceramic bearings and spline connections, is designed with heat insulation components and transmission components, including an outer cylinder made of high-temperature alloy material, an inner cylinder made of ceramic fiber board, a heat insulation pad made of mica material, a heat insulation pad made of metal ring, and a heat insulation seat made of ceramic fiber material. It blocks heat transfer in multiple dimensions and is connected to the cooling system through a spiral heat dissipation pipe to achieve efficient heat dissipation.
It effectively reduces heat transfer, controls the motor side temperature within a safe range, avoids jamming, ensures stable torque transmission, adapts to the heavy-load requirements of high-temperature pumps, solves the problem of damage to connecting parts caused by thermal expansion and contraction, and achieves stability in long-term high-temperature operation.
