Wuchang environmental protection whzg vacuum solid pump is a kind of vacuum negative pressure suction loading, pneumatic positive pressure delivery pump. The vacuum solid pump is completely powered by compressed air. It can transport pure solid particles, powder materials, all kinds of slurries, high concentration sludge, oily sludge, pulp, slag, and other bulk materials. Because the pump operation does not need electricity, only need compressed air, so Wuchang vacuum solid pump can be safely used in oil and gas, coal, chemical and other places with strict explosion-proof requirements. The main principle of pumping material transmission is the result of Venturi effect. The principle of Venturi effect is that when the wind blows through the barrier, the air pressure near the port above the leeward side of the barrier is relatively low, resulting in adsorption and air flow. According to the Venturi principle, the gas flow rate is accelerated to form a "vacuum" zone at the back of the venturi outlet. When the vacuum zone is close to the material, it will produce a certain adsorption.

Wuchang vacuum solid pump is a kind of pneumatic conveying pump with high load and strong suction, also called solid conveying pump. Able to pump solid, powder, liquid, oil, acid, salt and solid-liquid mixture. The vacuum degree is as high as 85kpa, and the head of discharged water is 120m. Its unique structural design enables it to operate efficiently in difficult environment with extremely low failure rate, almost no need to replace vulnerable parts, and it can quickly transport more than 80% of solid-liquid mixed materials and high specific gravity materials.

Working principle of vacuum solid pump

Open the air inlet of the vacuum solid pump, the compressed air enters from the venturi tube inlet, and a small part is discharged through the nozzle with a small cross section. As the cross section gradually decreases, the pressure of compressed air increases, and the flow rate also increases. At this time, a vacuum degree is generated in the inlet of the adsorption chamber, causing the surrounding air to be sucked into the venturi tube. With the compressed air flowing into the diffusion chamber, the flow rate of the gas increases, and then the airflow oscillation is reduced through the silencing device. A few seconds after the air enters the cavity, the material to be absorbed enters the cavity from the feed port of the cavity. The air inlet valve will change the direction of the air passage and generate positive pressure in the pump cavity. The material in the cavity will be squeezed out from the discharge port of the pump cavity through the discharge pipeline.
