[0002] A jet pump is a fluid conveying machine that uses a working fluid to transfer energy and mass. It includes an ejector and a working pump. The ejector is composed of a nozzle, a throat, a diffuser, a suction chamber and other components. Jet pump devices are mostly used in deep well operations.

[0003] After searching, the announcement number is CN109356888B, and the name is a jet pump, including an ejection fluid duct, a working fluid duct, a mixing tube and a honeycomb rectification structure. Through research and analysis, it is found that the device can reduce the turbulent pulsation of the ejected fluid when entering the mixing tube in a confined space, reduce the flow separation phenomenon and the vortex pair size at the bend when the fluid direction changes, and improve the uniformity of the ejected fluid, thereby improving the ejection capacity and anti-cavitation performance of the jet pump in a confined space. However, the following disadvantages still exist to a certain extent.

[0004] For example, when the equipment is in use, it mostly directly transfers gas or liquid, and does not have the function of filtering materials. When used for a long time, dirt is likely to remain in the conveying equipment, which easily sends dirt into the equipment. It also does not have the function of increasing the stability between components, so the components on the equipment are prone to loosening due to vibration. In order to solve the above technical problems, we have designed a jet pump device with a filtering function. Utility Model Content
