Howo Emergency Manual for Solving Common Faults of Sewage Suction Trucks

Howo sewer jetter truck is a powerful tool for sewage treatment in urban communities and factories. It can easily treat sewer sewage and industrial wastewater. As an essential model among sanitation trucks, the functions and operation methods of Howo sewer jetter truck are similar to those of other brands. However, during use, Howo sewer jetter truck often encounters various failures, and these failures may lead to more serious consequences if not resolved in time. Therefore, as a user of Howo sewer jetter truck, it is best to master some solutions to common faults in case of emergency.

The first thing to note is that if the vacuum gauge of the Howo sewer jetter truck reads too low or has no indication, it may be that the vacuum pump speed is too low, and the throttle should be increased at this time; or the vacuum gauge tube is clogged, and the blockage needs to be cleared; or the vacuum gauge If it is damaged, a new vacuum gauge needs to be replaced; it is also possible that the four-way ball valve is not opened in place, in which case the rotary vane needs to be replaced.

Secondly, if the hole cover of Howo sewer jetter truck leaks, there are several possible reasons. First, the left-hand screw is not screwed in place. At this time, you only need to tighten the left-hand screw; second, the sealing gasket is damaged and fails, and the solution is to replace the new sealing gasket; third, the tie rod is too long, and the length of the tie rod needs to be adjusted.

When the power take-off of the Howo sewer jetter truck makes abnormal noises and the temperature rises too high, there are two common reasons. First, the parts are worn, and the power take-off needs to be disassembled, cleaned and replaced. Second, the lubricating oil contains impurities or deficiencies. The solution is to replace Isuzu's suitable lubricating oil or add it in time.

If the vacuum pump of the Howo sewer jetter truck makes abnormal noise and the temperature rises too high, it may be that impurities have entered the pump chamber or debris has been generated. At this time, the vacuum pump needs to be disassembled, cleaned, and worn parts replaced; or the wheel sleeves are worn. At this time, new wheel covers need to be replaced; in addition, insufficient lubricating oil or mixed impurities may also cause such problems. The solution is to add or replace lubricating oil in time.

Finally, if your Howo sewer jetter truck's fuel tank is leaking, there are several possible causes. One is that the connecting screws are loose and only the bolts need to be tightened; the other is that the sealing gasket is damaged and a new sealing gasket needs to be replaced; another situation is that the amount of lubricating oil is too large. The solution is to adjust the position of the lubricating oil so that it Located in the middle of the liquid, that is, the appropriate position.

Through the above analysis, we can see the common faults and solutions during use of Howo sewer jetter truck. As long as we master the solutions to these common faults, we will be able to deal with the faults of the sewage suction truck in a timely manner to ensure its normal operation and improve work efficiency.
