Efficient two-stage oil liquid online bubble removing device

Abstract

The invention discloses an efficient two-stage oil liquid online bubble removing device. The bubble removing device comprises an oil-gas separating cylinder, a guide impeller, a gas outlet pipe, an upper cover for closing an upper opening of the oil-gas separating cylinder and an exhaust valve for fixedly connected to the upper end of the gas outlet pipe; the oil-gas separating cylinder comprises a cylindrical rotating cavity in the upper portion and a separating cavity coaxially and integrally formed in the bottom of the rotating cavity, an oil inlet pipe is arranged at one side of the rotating cavity in the tangential direction, and an oil outlet is formed in the bottom of the oil-gas separating cylinder. According to the online bubble removing device, the pure mechanical structure can be achieved, power is not needed, and the bubble removing device operates along with operation of oil liquid and can effectively accelerate bubble aggregation. As the rotating separation and filtering separation two-stage oil-gas separating mechanism is adopted, the overall separating effect is greatly promoted. The bubble removing device is convenient to install, extra matched design is not needed, and the install-and-play effect can be achieved. The online bubble removing device is small in size and light in weight, and the guide impeller is adopted and rotates to push oil liquid to rotate.

Description

Technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a high-efficiency two-stage oil on-line debubbling device. Background technique [0002] Oil is widely used in production, storage, transportation and system operation, so it is inevitable to mix air in the oil. The air is suspended in the oil as spherical bubbles with a small diameter, which causes the system to work poorly, such as the increase of oil temperature, cavitation, causing system vibration and noise, and indirectly accelerates oil pollution, thereby affecting the system The stability and performance of the system. [0003] In hydraulic system devices, oil tanks are generally used to remove air bubbles. The natural removal method of oil tanks is a method that relies on the buoyancy of the air bubbles themselves to rise to the surface of the oil and dissolve into the atmosphere. If the oil at the bubble interface does not move upwards, it must rely on its own ...

Problems solved by technology

Due to the stirring effect of the pump, the micronized bubbles are ejected at high speed through the valve port to become emulsified liquid bubbles. Even if they stay in the fuel tank for a long time, it is difficult to float up by themselves.
