Description
technical field [0001] The invention belongs to the field of centrifugal pumps, in particular to a bearing box device of a FZQ type tangential flow pump, which is suitable for transporting various clean flammable, explosive and strong corrosive media containing trace particles under the condition of -60°C to 200°C . Background technique [0002] FZQ type tangential flow pump is mainly used in petroleum, petrochemical, oil refining, power generation, papermaking, food and other industries. It is designed for small flow, high head, especially for pumps with solid medium that is easy to wear. The tangential flow pump is from zero flow to When the design flow rate changes, the head of the pump is constant. This feature is especially suitable for the occasions where it is used in conjunction with nozzles, and it is also suitable for other occasions that require the pump to have self-adjusting characteristics. Insensitive, when the gap increases due to grinding and corrosion, the...
