Problems solved by technology

[0003] The injectors in the prior art are all installed axially. The disadvantages of this injector are: 1. The length of the pump body is too long, which makes it inconvenient to use; 2. The axial installation size error of the nozzle and nozzle leads to performance degradation ; 3. The water flow noise of the injection pipe is loud when spraying

Abstract

The invention belongs to the technical field of ejectors, in particular to a radial ejector. The radial ejector comprises an ejector shell, a suction chamber, a mixing chamber and an ejection chamberare arranged in the ejector shell, and the suction chamber and the ejection chamber are arranged in parallel. The mixing chamber is arranged below the ejection chamber and communicates with the suction chamber. An ejection pipe is arranged in the ejection chamber, an ejection opening is formed in the radial side of the ejection chamber, and a suction opening is formed in the side, opposite to theejection opening, of the suction chamber in the radial direction and is connected with injection medium fluid. A nozzle is arranged at the bottom of the mixing chamber, and connected with work mediumfluid. According to the radial ejector, the length of a pump is shortened, performance reduction caused by the axial mounting size errors of the nozzle and a spraying pipe is avoided, and the performance of the ejector is improved; and water flow ejection noise is isolated through an ejector shell, and the water flow noise of the product is lowered.

Description

technical field [0001] The invention belongs to the technical field of injectors, in particular to a radial injector. Background technique [0002] An ejector is a pump that uses the jetting action of a high-pressure working fluid to deliver fluid. It is composed of nozzle, mixing chamber and injection pipe. For the sake of smooth operation, a vacuum chamber (also called suction chamber) is provided at the throat; in order to make the two fluids fully mix, there is a mixing chamber behind the vacuum chamber. During operation, the working fluid is ejected from the nozzle at a high speed, forming a low pressure in the vacuum chamber, so that the conveyed liquid is sucked into the vacuum chamber, and then enters the mixing chamber. In the mixing chamber, the high-energy working fluid and the low-energy liquid to be transported are fully mixed, so that the energy is exchanged with each other, and the speed is gradually consistent. When entering the diffusion chamber from the t...
