When it comes to the best sewage suction truck, we can always think of the figure that shuttles around the city, collecting, cleaning, transporting sludge and sewage, and protecting the environment from secondary pollution. How much do you know about the structure and working principle of the best sewage suction truck?  Let's get to know about it!

First, we look at the structure of the best sewage suction truck, which can be divided into two parts: chassis and upper mounting.

The chassis of the best sewage suction truck generally adopts the two general chassis commonly used by special vehicles. The upper installation of the best sewage suction truck refers to the special part of the best sewage suction truck, mainly including the power take-up device, transmission shaft, vacuum sewage pump, pressure tank body, hydraulic part, network management system, vacuum pressure gauge, suction pipe, sewage window, hand washing device, etc. The can body head of the best sewage suction truck is die-casting and can body can be opened from the back. The vacuum sewage pump equipped with the sewage suction truck has a high power and excellent hydraulic control system. Therefore, the best sewage suction truck has high suction efficiency, high vacuum degree of tank body (greater suction than the suction of the septic truck), large tonnage, long life, fast working speed, convenient transportation, quick operation and simple advantages, which are widely used in urban environmental protection.

After understanding the structure of the best sewage suction truck, and then look at the working principle of the car.

The working principle of the best sewage suction truck is very simple: the power output by the chassis engine is transmitted to the vacuum pump through the transmission, the power take-off device and the transmission shaft, and the vacuum pump starts to work. The air in the sewage suction truck is gradually removed, and it is thinner and thinner because it can not be supplemented. The air pressure in the tank becomes lower and lower. The vacuum pump works all the time, pumping the air from the tank to form a vacuum. Thus, the air pressure in the tank is far lower than the external atmospheric pressure. Under the action of atmospheric pressure, the sewage enters the tank through the suction pipe, which is the principle of sewage absorption.

The discharge of the dirt from the best sewage suction truck is in two ways: pressure discharge and self flow discharge. Pressurized discharge is to pressurize the tank body. Under the action of gas pressure, the sewage in the tank will be discharged automatically. The self discharge is simple. Open the back cover of the suction tank directly, and the dirt inside the tank will flow out by itself.
