Detailed Description

In order to facilitate an understanding of the invention, a full description thereof will be given below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "disposed" on another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Example 1

Referring to fig. 1 to 4, a pump body for a particle size analyzer includes a cylinder 1, and the cylinder 1 is a hollow structure.

Wherein, the upper portion of barrel 1 is the cylinder, and the middle part of barrel 1 is the back taper, and the lower part of barrel 1 is the disc.

Specifically, the lower part in the cylinder 1 is used for installing an impeller. The outer side surface of the lower part of the cylinder body 1 is provided with a medium inlet 2 communicated with the inside of the cylinder body 1. The outer side surface of the upper part of the cylinder body 1 is provided with a medium outlet 3 and an overflow port 4 which are communicated with the inside of the cylinder body 1, and the overflow port 4 is positioned above the medium outlet 3. A spoiler 5 is arranged on the inner side surface of the middle part of the cylinder body 1.

Wherein, evenly distributed is provided with a set of first protruding ear 6 on the upper portion lateral surface of barrel 1, all is equipped with first mounting hole 61 on every first protruding ear 6.

Specifically, a group of second protruding lugs 7 are uniformly distributed on the outer side surface of the lower part of the cylinder body 1, and each second protruding lug 7 is provided with a through second mounting hole 71. In this embodiment 1, the spoiler 5 is elongated.
