The working principle is the same as that of the externally mixed rubber pump. The difference is that the return water does not flow to the outer edge of the impeller and flows to the impeller inlet. When the internal mixing self-priming pump is started, the return valve in front of the impeller must be opened to allow the liquid in the pump to flow back to the impeller inlet. The water is mixed with the air from the suction pipe by the high-speed rotation of the impeller, and the gas-water mixture is discharged to the separation chamber. Here the air is discharged and the water is returned from the return valve to the impeller inlet. Repeat this until the air is drained and the water is sucked up.
The self-priming height of the rubber-lined pump is related to factors such as the front seal clearance of the impeller, the number of revolutions of the pump, and the liquid level of the separation chamber. The smaller the front seal gap of the impeller is, the larger the self-suction height is, which is generally 0.3~0.5 mm. When the gap is increased, the lift and efficiency of the pump are reduced except for the self-suction height. The self-priming height of the pump increases with the increase of the circumferential speed u2 of the impeller, but when the maximum self-suction height is increased, the number of revolutions increases and the self-suction height does not increase any more. At this time, only the self-priming time is shortened; When falling, the self-priming height decreases. Under other conditions, the self-priming height also increases with the increase of the storage height (but it cannot exceed the optimal storage height of the separation chamber). In order to better mix the gas and water in the self-priming pump, the blades of the impeller should be less, and the pitch of the cascade should be increased; and the semi-open impeller (or the impeller with a wider impeller channel) should be used, so that Convenient for the return water to penetrate into the impeller cascade.
