Howo Sewer Tanker Truck Driver’s Operating Points and Precautions

As countries around the world increase their environmental hygiene requirements, Howo sewer tanker trucks are used more and more frequently. Howo super sucker truck is a sanitation vehicle that effectively reduces environmental pollution and is an important vehicle among sanitation and greening vehicles. It is mainly used for collecting, transferring, cleaning and transporting sludge and sewage to avoid secondary pollution. Because the Howo cesspool truck has the function of self-priming and self-draining, the operation speed is fast, and it can easily suck up stones and larger stones in the sewer, so it is trusted by the majority of users. Then, a qualified  driver needs to do the following during the operation:

1. Ensure the normal working of the vacuum pump: The suction power of the Howo sewer tanker truck mainly comes from the vacuum pump, so the selection and maintenance of the vacuum pump is very important. It is necessary to maintain an appropriate number of revolutions. If the speed is too high, the rotor will heat up. If the speed is too low, it will cause additional impact on the engine and components and affect the service life. In order to achieve the appropriate operating speed, it is necessary to adjust the optimal position of the hand throttle according to the pump type in advance.

2. Choose a flat location for the unloading operation: Howo sewer tanker truck is usually equipped with a lifting dump system, which can dump and unload materials by itself. Therefore, it is best to choose a relatively flat area when performing soil removal operations. When unloading dirt, it is prohibited to operate on uneven or inclined roads, because unloading dirt on inclined roads will cause deformation and failure of vehicle parts and may lead to rollover accidents.

3. Open the back cover of the tank before unloading dirt: Before unloading dirt, open the back cover of the tank first. Before unloading dirt, loosen the locking bolts and lift the back cover to the appropriate position. When the tank is fully loaded, it is forbidden to lift the tank with the back cover closed, otherwise the center of gravity will shift backwards, which may easily cause a rollover accident.

4. Vacuum pump and oil pump power taking operation: When performing power taking operation of the oil pump and vacuum pump, the engine should be at idle speed, fully depress the clutch pedal, and then slowly release the clutch pedal.

5. When the Howo sewer tanker truck is driving, the vacuum pump and oil pump are stopped.

6. It is prohibited to inhale and transport waste oil and hazardous substances: Howo sewer tanker truck must not be used to inhale and transport waste oil and hazardous substances to avoid serious accidents such as fires and explosions. Safety first, always remember.

7. When entering the bottom of the tank or performing maintenance on the Howo sewer tanker truck while the tank is lifted, support rods and safety stops must be used.

8. When transporting dirt, keep driving at a medium or slow speed: When Howo sewer tanker truck transports dirt, the driving speed of the vehicle should be kept at a medium or slow speed. Do not make sharp turns or brakes, because generally the light duty Howo sewer pump truck does not have a wave barrier inside the tank, and the vehicle has a higher center of gravity.

The above are the key points that a qualified Howo sewer pump truck driver needs to do during the operation. Only by operating in accordance with these requirements can the safety and normal operation of the Howo sewer tanker truck be ensured and environmental pollution effectively reduced.
