Profile

Suction sewage truck is a new type of environmental sanitation vehicle for collecting, transferring and cleaning transportation sludge and sewage to avoid secondary pollution, the utility model can do suction and discharging by itself, working speed fast, large capacity and convenient transportation, it suitable for collecting and transporting liquid substances such as excrement, mud, crude oil and so on. The vehicle’s vacuum pump which is adopts leading domestic technology, it will provide powerful suction and suction range, especially suitable for loading and unloading the sediment in the sewer, especially suitable for suction, loading and discharging such as mud, silt, stones and bricks where depositing in the sewer.

Technical characteristic

- The tank is made of high quality steel plate, durable and coated with anti-corrosion of anti-rust paint inside the tank.

- The tank is provided with an overflow preventing valve, to prevent the vacuum pump suction much more due to overflow tank, and four-way valve changes direction to carry out vehicle suction operation or discharge operation.

- The suction power system takes the force on the gear box, and the system is equipped with an oil-water separator which can effectively separate the oil-water.

- Suction power system take the force from gear box, and oil-water separator can be used to separate oil-water effectively.

- The sealing of the tank adopts hydraulic and mechanical, which is safety and reliable.

- The unloading of the vehicle adopts hydraulic lifting and discharging, which is stable and reliable.

- Operating system is simple and convenient.

Technical specification

Function

The equipment consists of oil-water separator, water separator, hydraulic dump device, special vacuum suction pump, pressure volume table, smoking pipe, gravity flow valve, vacuum tank, connecting device (dung window), automatic anti overflow valve, hydraulic component Suite.

The special part depending on the vehicle by the suction force taking device, transmission shaft, vacuum suction pump, pressure tank, hydraulic parts, pipe network system, vacuum pressure gauge, dung window, hand washing device; Vehicle equipped with high power vacuum suction pump and high quality hydraulic system. The sewage in tank can be dumped directly through the rear cover. The utility model has the characteristics of high vacuum, large tonnage, high efficiency and wide application.

Working Principle

The suction hose always immersed above the liquid, When the air in the tank is pumped, it gets thinner and thinner because it is not replenished, the resulting make pressure in the tank less than the atmospheric pressure, under the atmospheric pressure, the sewage enters the tank through the dirt suction hose. Or the siphon hose approaches the bottom of the tank, means its under the action of compressed air, through siphon pipe, suction pipe discharged out of the tank.

Application Notice

Larger than 50mm such as stones , cotton yarn, leaves and other impurities will clog the straw. Therefore, do not inhale and should clean it frequently.

When the vacuum meter readings reach to 65-80 thousand Pascal, the ball valve should be completely opened , half - open condition can damage the valve heart , and suction sludge should be moved straw regularly, if inhaling high viscosity sludge, should be sucked air and water in occasionally, it can improve efficiency.

Different with fecal suction truck

Suction sewage truck and fecal suction truck has the same working principle, but suction sewage truck and fecal suction truck have different purposes. The difference is : the tank is a circular tank, and the structure is much more compact, it will resist higher pressure to provide greater suction, it also can be used for collecting, cleaning and transportation sewage and sludge.
