Shacman 4X2 F3000 16000-22000 Suction Sewerage Vacuum Sewage Suction Truck Hot Sale From Original Factory

A sewage suction truck, also known as a vacuum sewage truck or vacuum tanker, is a specialized vehicle designed to remove and transport sewage, sludge, and waste materials from sewer systems and septic tanks. Below is a detailed introduction:
Main Components
Vacuum Pump: The heart of the sewage suction truck, it creates suction by reducing pressure inside the tank, enabling the truck to extract sewage and other liquid waste from underground septic tanks, manholes, and sewer lines. The vacuum pump is typically driven by a power take-off (PTO) unit connected to the truck’s engine. Its performance directly impacts the truck’s suction power and efficiency.
Storage Tank: Designed to hold large volumes of liquid waste, the tank is usually made of durable materials such as steel or aluminum to withstand the corrosive nature of sewage. Some tanks feature compartments to separate different types of waste and are equipped with safety features like anti-spill mechanisms and monitoring systems to prevent leaks and spills.
Hydraulic System: Consisting of an oil tank, oil pump, multi-way directional valve, hydraulic cylinders, oil filter, and piping, this system enables the self-dumping of waste inside the tank. By controlling the multi-way directional valve, operators can complete self-dumping operations.
Water Jetting System: Found in jetting trucks and combination trucks, this system uses high-pressure water jets to dislodge blockages and debris from pipes or sewage infrastructure. It typically includes a high-pressure pump, powered by the truck’s engine, and a hosing system with various nozzles designed to direct water in specific patterns to optimize cleaning.
Working Principle
The vacuum pump creates negative pressure inside the tank, and atmospheric pressure forces sewage into the tank through suction hoses. During discharge, the sewage is transported to treatment facilities or disposal sites via the discharge system. Some sewage suction trucks also feature a reverse mechanism, allowing the vacuum pump to draw clean water from a reservoir into the pipelines for high-pressure flushing to clear clogs.
Types
Vacuum Tanker Trucks: The most common type of sewage truck, equipped with a large vacuum pump and storage tank. They are ideal for routine waste collection.
Jetting Trucks: Combine the functions of a vacuum tanker and a high-pressure water jetting system. In addition to collecting sewage, they can clean sewer lines and remove debris and blockages.
Combination Trucks: Integrate the features of vacuum tanker trucks and jetting trucks, equipped with both a vacuum system and a high-pressure water jetting system. They efficiently collect sewage and clean sewer lines, making them suitable for municipal applications where both tasks are required.
Features and Advantages
High Suction Efficiency: The vacuum pump generates strong suction power, enabling the vehicle to suck sewage and silt from sewers and septic tanks. Some sewage suction trucks can achieve a suction depth of over 6 meters and a horizontal suction distance of up to 20 meters or more.
Wide Application Range: Suitable for cleaning and maintaining urban and rural sewers, septic tanks, and cesspools. They can transport feces, sewage, mud, and liquids mixed with small suspended particles. They are widely used in municipal sanitation, industrial and mining enterprises, residential communities, schools, and other settings.
Strong Environmental Adaptability: Capable of adapting to various harsh working environments, they provide strong support for emergency rescue and sanitation efforts in floods, natural disasters, or infrastructure failures.
High Degree of Automation: The truck can perform tank lifting and unloading, and the rear door can open and close automatically. It features high vacuum levels, low noise, uniform airflow, self-suction, self-discharge, and self-dumping capabilities, reducing manual labor and improving work efficiency.
Durable Construction: The tank is made of high-quality materials such as 4-6mm carbon steel, with the tank head molded in one press. It can open at the back and features dual top self-dumping functionality. The waste inside the tank can be directly dumped through the rear cover, facilitating the cleaning of sediment and solids inside the tank as well as the maintenance and repair of the tank interior.
