Embodiment Construction
[0010] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0011] like figure 1 , 2 As shown, the side channel pump includes a pump body 91, a motor 90 connected in transmission with the pump body 91, and a balanced sealing structure arranged in the pump body 91. The balanced sealing structure includes a base 8, a rotating shaft 1, a casing 2, Housing 4, first clamping plate 3, second clamping plate 5, the rotating shaft and the base are rotatably connected through bearings 9, the sleeve is fixedly sleeved on the rotating shaft, and the first clamping plate has four , and divided into two groups, which are arranged symmetrically on the outer side of the sleeve respectively. The two first clips of the same group form a first clip slot, and the first clip slot is provided with a There are four first sealing strips 7, and there are four second clips, which are divided into two groups and symmetrical...

The invention discloses a side runner pump which comprises a pump body, a motor and a balanced seal structure. The balanced seal structure comprises a base, a rotary shaft, a sleeve pipe, a shell, first clamp plates and second clamp plates. The rotary shaft and the base are rotationally connected through a bearing. The sleeve pipe is fixedly arranged on the rotary shaft in a sleeving manner. The number of the first clamp plates is four, every two first clamp plates in the same set form a first clamp groove, and a first sealing strip attached to the inner side wall of the shell in a sealed manner is arranged in each first clamp groove. The number of the second clamp plates is four, and the second clamp plates are divided into two sets to be symmetrically arranged on the inner side wall of the shell correspondingly. Every two second clamp plates in the same set form a second clamp groove, a second sealing strip attached to the inner side wall of the shell in a sealed manner is arranged in each second clamp groove, and the second sealing strips are attached to the sleeve pipe in a sealed manner. Due to the fact that two seal mechanisms are adopted, dual seal is adopted by each seal mechanism, the first sealing strips are clamped in the first clamp grooves, and the second sealing strips are clamped in the second clamp grooves, seal performance is greatly improved, and normal running of the pump is guaranteed.
Description
technical field [0001] The invention belongs to the field of water pumps and relates to a side channel pump. Background technique [0002] The single-balanced seal structure of the multi-stage side channel pump is installed behind the final impeller and rotates with the shaft, and a gap is formed between the outer surface of the drum and the shell. In front of the drum is the rear pump chamber of the final impeller, and the rear is connected to the suction port. In this way, the pressure difference acting on the drum forms a force opposite to the hydraulic axial force to balance the axial force. If the seal is not good enough, the friction between the impeller and the pump casing will cause wear. Contents of the invention [0003] The object of the present invention is to provide a side channel pump in order to overcome the deficiencies of the prior art. [0004] In order to achieve the above purpose, the technical solution adopted in the present invention is: a side ch...
