Horizontal multi-stage water feeding pump

Abstract

The invention relates to the field of water pumps, in particular to a horizontal multi-stage water feeding pump which comprises a water feeding pump body, a water inlet pipe, a water outlet pipe, a sliding structure, a pipeline, a piston ring, a circular ring, connecting rods, a sliding rod, fixing rings, first springs, a clamping structure, a circular rod, swing rods, fan-shaped rods, connectingblocks, rubber pads, a supporting rod, a second spring and a fixing structure. According to the horizontal multi-stage water feeding pump provided by the invention, by arranging the piston ring, whenthe water feeding pump body needs to be used, a water conveying pipe needing to be connected to the water inlet pipe is inserted into the water inlet pipe and then abuts against the piston ring first,the piston ring slides inwards to drive the circular ring and the connecting rods to move, and the circular ring and the connecting rods move to drive the sliding rod to slide; and when the sliding rod slides, the two swing rods are driven to move, the supporting rod also enables the two swing rods to relatively rotate and be separated along with movement of the sliding rod, accordingly, the twoswing rods relatively rotate till the two rubber pads abut against the inner walls of the top and the bottom of the water conveying pipe correspondingly, and at the moment, the water conveying pipe isfixed by the two rubber pads from the interior.

Description

technical field [0001] The invention relates to the field of water pumps, in particular to a horizontal multi-stage water feed pump. Background technique [0002] Horizontal multi-stage feed water pump refers to horizontal multi-stage boiler feed water pump, which is a single-suction horizontal multi-stage segmented multi-stage centrifugal pump. Horizontal multi-stage boiler feed water pump is mainly used for boiler water supply and drainage or The transportation of hot water, so the boiler pump is also called the feed water pump. The temperature of the medium conveyed by the multi-stage boiler feed water pump cannot exceed 120 degrees. If the temperature of the conveyed medium exceeds 120 degrees, it is necessary to equip a cooling system and adopt a special sealing method according to the actual working conditions. [0003] When the existing horizontal multi-stage feed water pump is used to deliver water at higher floors, it is necessary to connect a water delivery pipe b...

AI Technical Summary

Problems solved by technology

[0003] When the existing horizontal multi-stage feed water pump is used to deliver water at higher floors, it is necessary to connect a water delivery pipe between the water source and the feed water pump so that the feed water pump can pump water. However, the existing feed water pump usually passes through the flange The connection and fixation of the water pipe and the screw are realized, so the installation process of the water pipe and the water supply pump not only requires tools, but also the operation is more cumbersome
