Suction & Pressure Vehicle

Suction & Pressure Vehicle: Product Details & Core Advantages

I、Product Definition & Core Value

A Suction & Pressure Vehicle, also known as a Vacuum Suction & Pressure Tanker or Pneumatic Suction-Discharge Truck, is a specialized tanker integrating vacuum suction and positive pressure conveying functions. Powered by the onboard diesel engine driving a Roots vacuum pump and air compressor, it enables enclosed suction, transportation, and high-pressure discharge of powdered materials, granular materials, and secondary pollutants.

Its core value lies in the "fully enclosed, dust-free" clean transport model. This vehicle fundamentally solves the problems of spillage and dust pollution associated with traditional bulk material transport. It is key equipment for achieving green production and clean transportation in industries such as steel, power, cement, and chemicals.

II、 Product Details & Technical Specifications

1. Main Structural Components

Chassis System: Built on reputable second-class commercial vehicle chassis from manufacturers like Dongfeng, Sinotruk, and Shacman, equipped with a diesel engine for strong power and adaptability to complex operating conditions.

Vacuum Suction System: Comprises a Roots vacuum pump and piping system, designed to generate high negative pressure, drawing materials into the sealed tank through enclosed pipelines.

High-Pressure Pneumatic Conveying System: Consists of an air compressor and piping system, generating positive pressure to discharge materials at high pressure from the tank through sealed pipelines into designated storage facilities.

Dust Filtration System: Features a high-efficiency material-air separation device inside the tank, filtering dust from the incoming mixed airflow to ensure clean exhaust emissions and prevent air pollution during operation.

Tank & Tipping System (Optional): A sealed tank manufactured from high-strength steel, featuring a closed top and a non-opening rear to guarantee leak-proof transport. Some models are equipped with a hydraulic tipping function to assist discharge.

Hydraulic Outrigger System: Deployed during operation to ensure vehicle stability and safety when performing heavy-duty suction or discharge.

2. Operating Principle & Workflow

The vehicle enables fully enclosed material-air conveying through specialized devices:

Suction Loading: The engine drives the Roots vacuum pump, creating high negative pressure inside the tank (typically reaching -50kPa to -80kPa). Materials are drawn into the sealed tank through a suction hose. As the mixed airflow passes through the dust filtration system, materials are separated from the air—clean air is exhausted into the atmosphere, while materials settle inside the tank.

Enclosed Transportation: Materials are transported within the fully sealed tank, ensuring zero spillage, zero dust, and zero leakage.

High-Pressure Discharge: Upon arrival at the discharge point, the engine switches to drive the air compressor, generating high positive pressure (typically 0.2MPa to 0.4MPa). The material inside the tank is fluidized and pneumatically conveyed at high pressure through sealed pipelines into dedicated storage facilities (such as silos). The discharge process is equally dust-free and environmentally friendly.

3. Key Technical Parameters (Reference Values)

Chassis Axles: Commonly 4-axle (8×4) heavy-duty or 3-axle (6×4) heavy-duty models, with Gross Vehicle Weight (GVW) ranging from 25 tons to 31 tons.
