Isuzu sewage suction truck

Isuzu vacuum tanker is a new type of sanitation vehicle that collects, transfers, cleans and transports sludge and sewage to avoid secondary pollution. Isuzu vacuum tanker can self-prime and discharge. It has fast working speed, large capacity and convenient transportation. It is suitable for collecting and transporting feces, mud, Liquid substances such as crude oil. Isuzu vacuum tanker adopts domestic technology-leading sewage suction truck vacuum pump, with large suction power and long suction range. Isuzu vacuum tanker is particularly suitable for suction, transportation and discharge of sludge in sewers, especially for suction of sewer mud, sludge, Larger objects such as stones and bricks.

The use process of Isuzu vacuum tanker is mainly divided into several steps: before suction, suction, discharge and recovery. Drivers can just follow the specific operation guide of each step.

Preparation steps before vacuuming dirt with Isuzu vacuum tanker:

1. Close the large tank cover, drain valve cover, and pressure reducing valve tightly to prevent air leakage.

2. Insert the boom suction tube into the liquid surface.

3. Turn the four-way valve handle to the pumping position. ​

4. Start the engine at idle speed.

Isuzu vacuum tanker suction operation method:

1. Prepare for operation before inhaling the Isuzu vacuum tanker. Close the rear door of the tank and observe whether the lubricating oil of the vacuum pump oil and gas separator is normal.

2. Depress the clutch pedal, push the power take-off lever to run the vacuum pump of the sewage suction truck, and then slowly release the clutch pedal.

3. Turn on the alarm switch in the cab.

4. Pull the throttle handle to the maximum position, observe the tachometer, and make it reach 500-600 rpm (it has been adjusted at the factory).

5. Place the four-way valve switching handle in the suction position, and check whether the air discharged from the trachea is correct, whether there is any sound when the vacuum pump is running, and whether the vacuum gauge is normal.

6. Remove the sewage suction hose from the Isuzu vacuum tanker and put it into the sediment well. In order to keep the sewage suction hose in a straight line or freely bent state, the parking position should be fully considered.

How to discharge sewage from Isuzu vacuum tanker:

After the mud and water are separated, open the drainage ball valve, drain the sewage and then suck the mud again. You can also pressurize and drain quickly. The operation method is as follows.

1. Place the four-way valve switching lever in the "neutral" position, and then place the drainage ball valve in the "open" position to drain sewage reliably by gravity.

2. Switch the four-way valve to the discharge position and the vacuum pump continues to work, then the compressed air and sewage flowing into the tank will be quickly discharged.

3. When draining pressure, the discharge ball valve should be opened first, and then the four-way ball valve can be moved to the discharge position to avoid excessive pressure in the tank, causing accidents and affecting the tank door seal.

How to discharge sludge from Isuzu vacuum tanker:

1. Depress the clutch, move the pneumatic reversing valve to the open position, or push the power take-off lever to run the oil pump.

2. Open the tank door ball valve, discharge part of the sewage, and reduce the pressure in the tank to communicate with the atmosphere.

3. Loosen the tank door locking device, loosen the handle and completely pull out the screw.

4. Set the tank door opening and closing lever of the manual reversing valve to "open". Before opening, confirm that the pressure in the tank is equal to atmospheric pressure. If the tank door is opened under negative pressure, the tank door sealing ring and the oil cylinder will be damaged.

5. Place the hydraulic lift valve stem of the manual reversing valve in the "up" position.

During the recovery operation after discharging the sludge, place the hydraulic cylinder operating lever in the "lowering" position, and check the following after safely descending:

1. Check whether there is dirt on the tank door flange and sealing ring, and scrub them clean with a brush.

2. Set the tank door opening and closing lever to "close" and close the door safely.

3. Insert the screw of the clamping device into the screw hole on the side of the tank and turn the handle until the rear tank door is pressed tightly.

Precautions for suction work with Isuzu vacuum tanker:

1. Stones larger than 50mm, cotton yarn, leaves and other impurities will block the straw. So do not inhale and remove frequently.

2. When the vacuum gauge reading reaches 65-80 kPa, fully open the ball valve of the sewage suction truck. The half-open state can easily damage the valve core. As the sludge is being sucked in, the suction pipe should be moved frequently. When high-viscosity sludge is sucked in, occasionally inhale it. air and water to increase pollution efficiency.
