Sewage and sewage suction machines are mainly used for pumping sewage, mud sludge and liquids mixed with small suspended particles, suitable for sewage disposal, property management and municipal departments in large, medium and small cities;
The tank type is an oval tank, equipped with a vacuum suction pump, a water and oil separator and a 5 meter long feces suction pipe.
When the eccentric rotor rotates, the rotary vane slides against the inner wall of the pump under the action of centrifugal force. The rotary slide rotates until the end of suctions, the intake gas is insulated.
The rotor continues to rotate, the isolated gas is gradually compressed and the pressure increases. When the pressure exceeds the outlet port pressure, the gas is discharged from the pump. In this way, the vacuum pump of the sewage suction vehicle circulates again and again and the air in the container is sucked out, creating a vacuum.
The purpose of the vacuum pump of the sewage suction truck is to evacuate the air in the tank of the sewage suction truck to make the inside of the tank in a vacuum state. Was sucked into the glass.
Empty the air in the tank to put the tank in a vacuum state, and then pump the sewage from the outside through the pipe into the tank. In addition, the waste water in the tank is drained by pressurizing the tank.
The so-called vacuum pump is designed to pump the air in the tank into a vacuum that can suck in waste water and dirt under pressure. Includedit is a physical effect.
