Isuzu super sucker truck is a high-end sanitation vehicle. It has the advantages of self-priming and self-draining, fast working speed, and convenient transportation. It is mainly used for sewer sewage suction, loading and discharge, and is used in sanitation work in cities and towns. plays an important role.

Let us take a closer look at the operating specifications of Isuzu super sucker trucks.

1. Pre-start inspection and preparation

A. Check whether the engine oil, diesel, hydraulic oil, battery, tires, instruments, lights, etc. are normal, and check whether the safety facilities are complete.

B. The rear of the septic suction truck should be as close to the operating point as possible and park.

C. Open the side door of the walking platform box, take out the fecal suction hose, and swing it backward without bending.

2. Start operation

A. Pump the suction hose into the liquid level as deeply as possible, ensuring that the pipe end is always less than 300mm away from the liquid level during operation.

B. Push the handle of the four-way valve until it is perpendicular to the ground.

C. Put the transmission into neutral, then start the engine, disengage the clutch, pull the power take-off switch backward to put the power take-off into gear, and the vacuum pump starts running.

D. The operator should pay attention to monitor the situation near the inlet of the suction hose and use appropriate tools to block debris to avoid blockage.

E. The operator can pass the observation mirror on the upper part of the rear head. When the liquid level reaches the middle of the observation mirror, the driver should be notified, and colleagues should quickly pull the fecal suction hose off the ground or close the four-way valve. Under normal circumstances, the buzzer will emit an audible and visual signal at this time. When the driver receives the signal, he should reduce the throttle, push the power take-off switch forward and out of gear, the vacuum pump will stop rotating, and press the buzzer switch to cut off its power supply. .

F. Close the fuel tank straight-through cock handle plate parallel to the axis of the inlet mailbox.

G. After flushing the hose, put it back into the walking platform box, close the side door, and make the boom face above the cab.

H. Close the anti-overflow valve and make its handle perpendicular to the road axis.

I. Drive the fecal suction truck away from the operation site.

3. Shutdown operation

A. Point the water-absorbing hose into the sewage tank.

B. Pull the rear handle of the four-way valve until it is parallel to the ground, and open the anti-overflow valve until its handle is parallel to the axis of the pipeline.

C. Put the transmission into neutral, then start the engine, disengage the clutch, pull the power take-off switch back to put the power take-off into gear, the vacuum pump starts to run, put the transmission into neutral, then start the engine, disengage the clutch, and move the power take-off Pull the switch back to shift gears and take power, and the vacuum pump starts to run.

D. After the liquid in the tank is drained, the driver should promptly push the power take-off control handle forward to disengage the gear and stop the vacuum pump.

E. Close the fuel tank straight-through cock handle plate parallel to the axis of the inlet mailbox. After flushing the hose, put it back into the platform box, close the side door, and make the boom face above the cab.

F. Drive the sewage suction truck away from the operation site.

4. Maintenance

A. Routine maintenance is performed by the driver himself. Once a day, the driver should perform routine maintenance before leaving the vehicle, while driving, and after parking.

B. First-level maintenance is performed once a month, focusing on cleaning, lubrication, and tightening.

C. Second-level maintenance, once every quarter, is in addition to the first-level maintenance work and mainly focuses on inspection, anti-corrosion and adjustment.

5. Things to note

A. To work the vacuum pump of a sewage suction truck, you must first understand its working principle. The most important thing in the working principle is the source of power and the consideration of stability. The vacuum pump is powered by the chassis engine. The engine is transmitted to the vacuum pump through the gearbox, power take-off, and drive shaft. During the sewage suction operation, the vacuum pump draws out the air in the sealed tank to form a negative pressure, and uses the atmospheric pressure outside the tank to press the sewage into the tank through the sewage suction pipe. When discharging sewage, the vacuum pump pushes the atmospheric pressure outside the tank into the tank, and uses air pressure to discharge the dirt out of the tank (the continuous working time of the vacuum pump generally does not exceed 30 minutes).

B. The flow sequence of the air flow in the air path is: when suctioning sewage, the vacuum pump sucks the air with a certain humidity in the tank into the water-gas separator, where the water is separated and flows back into the tank. The gas passes through the four-way valve along the pipeline. Enter the vacuum pump air inlet. It is mixed with lubricating oil in the pump and discharged from the exhaust port through the compression chamber. In particular, the mixture is initially separated through the coarse filter, and the separated oil flows back to the oil pump. The mixed gas is further separated by the oil and gas separator, and then enters the four-way valve and is discharged into the atmosphere. The direction of air flow can be changed by manually operating the four-way valve, allowing for free suction and discharge.

C. When the vacuum pump of the sewage suction truck is completed each time, corresponding inspections of the sewage suction truck must be made according to the different work intensity to ensure the working life and second working efficiency of the sewage suction truck.
