• Working Principle:
The rotary vane vacuum pump consists of an eccentric rotor, sliding vanes, a pump chamber, and suction and exhaust valves. The motor drives the rotor to rotate eccentrically. Under centrifugal force, the vanes in the rotor slots adhere tightly to the chamber wall, dividing the chamber into multiple independent air chambers. As the rotor rotates, the suction chamber expands, drawing in gas; subsequently, the air chamber volume decreases, compressing the gas; when the pressure opens the exhaust valve, compressed air is discharged. This cycle continues, continuously drawing air from the sealed space to create a vacuum.
The Weilong pump uses oil-lubricated seals, ensuring excellent airtightness. The double-unit model allows for simultaneous pumping from both chambers, significantly increasing the suction flow rate, making it suitable for sewage and sludge pumping applications.

• Supporting Protection and Control:
The system is equipped with a four-way ball valve to switch between suction and discharge directions; a float-type anti-overflow device is installed on the tank top, automatically closing the suction port when the liquid level in the tank is close to full to prevent sewage backflow into the pump; additionally equipped with primary and secondary oil-gas separators and water-gas separators to ensure stable operation of the pump in humid gas environments.

★ Other Equipment:
• Hydraulic Control System
A manual hydraulic control valve is installed on the left side of the cab for centralized control of tank lifting and lowering, and tailgate opening and closing. An independent hydraulic oil tank ensures stable oil supply, and the hydraulic components are durable and leak-proof.
• Piping Unloading Assembly
A dedicated drain valve is installed at the rear of the vehicle, and a suction valve is located on the right side. The tailgate is equipped with a mechanical locking device to ensure a tight seal during operation and prevent sewage leakage.
• Practical Accessories
A maintenance ladder is installed on the side of the tank for easy access to the top for maintenance. A sight glass allows for easy observation of the liquid level inside the tank.
