Embodiment Construction

[0028] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0029] Such as Figure 1-3 As shown, the pump includes a pump body 11 with a cavity, a rotating shaft 1 set in the cavity, and an impeller 2 and a guide vane 3 sleeved on the rotating shaft 1, and the guide vane 3 is inserted on the mouth ring of the impeller 2 . The self-adaptive adjusting mouth ring device includes a top piece 4, an adjustment ring 5 and a bottom piece 7 which are sheathed on the mouth ring of the impeller 2 in sequence. A closed chamber is formed between the top piece 4 and the mouth ring of the impeller 2 and the guide vane 3, and there is an opening 61 between the top piece 4 and the mouth ring of the impeller 2 to allow the reflux liquid generated at the mouth ring of the impeller 2 to enter the cha...

Abstract

The invention provides a self-adaptive opening ring adjusting device for a pump and belongs to the technical field of machinery. The self-adaptive opening ring adjusting device solves the problems that an existing self-adaptive sealing device for the pump is large in pressure loss, high in requirements on mounting size, low in production efficiency and poor in production quality. The pump comprises a rotating shaft, impellers sleeved on the rotating shaft and guide blades, the guide blades are inserted in opening rings of the impellers, the self-adaptive opening ring adjusting device comprises ejection pieces and adjusting rings which are sequentially sleeved on the opening rings of the impellers, a sealed cavity is formed among each of the ejection pieces, each of the opening rings of the impellers and each of the guide blades, the adjusting rings are arranged in the cavities and closely fit with the opening rings of the impellers, and first openings capable of enabling backflow liquid generated at the positions of the opening rings of the impellers to enter the cavities are formed between the ejection pieces and the opening rings of the impellers. The self-adaptive opening ring adjusting device has the advantages that pressure loss is effectively reduced, efficiency of the pump is increased, requirements on precision of the mounting size are lowered, and manufacturing and mounting are facilitated.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to an adaptive adjustment mouth ring device for a pump. Background technique [0002] A pump is an energy conversion device that is controlled by the prime mover, drives the medium to move, and converts the energy output by the prime mover into the pressure energy of the medium. It is mainly used to transport liquids, including water, oil, acid and alkali, emulsions, suspoemulsions and Liquid metal, etc.; liquid, gas mixture and liquid containing suspended solids can also be transported. According to the working principle, the pump casing is divided into positive displacement pump, impeller pump and jet pump. The impeller pump relies on the impeller to drive the liquid to rotate at a high speed to transfer the mechanical energy to the liquid being transported. The impeller of the impeller pump is installed in the pump casing and fastened on the pump shaft, which is directly driven...
