High viscosity medium jet pump

Abstract

The invention relates to the technical field of injection pumps, in particular to a high viscosity medium injection pump. The structure of the high viscosity medium injection pump basically resembles that of the common injection pump and is formed by the combination of an inlet pipe of working fluid, a nozzle pipe, an accepting chamber, a diffusing pipe and a mixing chamber in sequence, wherein, the side of the accepting chamber is communicated with an absorption pipe, the inlet pipe of working fluid is provided with a throttle which can adjust the flow of dynamic energy fluid, the mixing chamber is internally provided with a three-level stepped diffusion platform and the injected fluid disperses evenly when passing through the three-level stepped diffusion platform and is mixed with the air in the mixing chamber before flowing into an oil cylinder. The arranging of the three-level stepped diffusion platform can lead the high viscosity working fluid in the injection pump to evenly and fully disperse and overcome the limit that high viscosity medium can not be taken as the working medium in the ordinary injection pump.

Description

technical field [0001] The invention relates to the technical field of jet pumps, in particular to a high-viscosity medium jet pump. Background technique [0002] Nowadays, cement equipment is constantly updated. Modern cement manufacturing companies use high-efficiency and energy-saving vertical mills as the main production equipment. The roller bearings of vertical mills need high-viscosity lubricating oil to circulate in the bearing cavity and take away the temperature and temperature generated by it. Pollutants, in order to ensure that there is a certain amount of lubricating oil in the bearing cavity but not lower than the required oil level, one pump must absorb oil from the bearing cavity, and the other pump must deliver oil to the bearing cavity.

[0002] Nowadays, cement equipment is constantly updated. Modern cement manufacturing companies use high-efficiency and energy-saving vertical mills as the main production equipment. The roller bearings of vertical mills need high-viscosity lubricating oil to circulate in the bearing cavity and take away the temperature and temperature generated by it. Pollutants, in order to ensure that there is a certain amount of lubricating oil in the bearing cavity but not lower than the required oil level, one pump must absorb oil from the bearing cavity, and the other pump must deliver oil to the bearing cavity. It is possible to choose an ordinary quantitative pump It will cause excessive suction and damage the suction pump, or the quantitative pump will cause too small suction and the lubricating oil will overflow from the bearing cavity and cause waste. Using a jet pump can solve this problem very well, but the vertical mill uses Bearing lubricating oil should be ≥220#, the viscosity of this oil is very high, this kind of high viscosity medium cannot spread well in the ordinary jet pump, and the mixing chamber cannot reach a certain degree of vacuum to produce oil absorption
