Abstract

The invention discloses a new structure multifunctional composite pumping device. The new structure multifunctional composite pumping device comprises a transmission device, a conveying device and anauxiliary device. The transmission device is mainly composed of a driving shaft and a driven shaft which are in a pair, the installing direction of the driving shaft is perpendicular to the installingdirection of the driven shaft, and torque is transmitted between the driving shaft and the driven shaft through a pair of bevel gears. The two bevel gears are arranged on the driving shaft and the driven shaft correspondingly. The conveying device is mainly composed of two impellers and two volutes. The two impellers are arranged at the two ends of the driven shaft correspondingly and matched with the two volutes correspondingly. The auxiliary device is mainly composed of a bridge frame, bearings and sealing covers. The driving shaft and the driven shaft are arranged in the bridge frame through the bearings. Due to lubricating oil in the bridge frame, the lubricating function is ensured. Due to the sealing covers at the upper portion and the front portion of the bridge frame, it is ensured that lubricating oil does not leak. The bridge frame and the two volutes are connected into a whole through bolts. The new structure multifunctional composite pumping device is simple in structure,small in size and capable of automatically balancing the axial force of the impellers; the conveying amount is increased; and different media can be conveyed and mixed.

Description

technical field [0001] The invention relates to a pumping device with a new structure, in particular to a composite pumping device which utilizes two mutually perpendicular transmission shafts and two independent pumping units to complete fluid medium delivery. Background technique [0002] Centrifugal pumps are widely used to transport various fluid media. However, when a large flow rate needs to be delivered, two pumps are often connected in parallel; and a single pump generally has the problem of excessive axial force, which may easily lead to a reduction in the pump's operating life; in addition, two pumps in parallel require more Large space is placed, and the power source becomes complicated. Based on this, this patent proposes a multi-functional composite pumping device with a new structure, which is compact in structure, saves installation space, well balanced in axial force, and delivers large flow. [0003] The composite pumping device has the characteristics of ...
