Isuzu sewage suction truck equipped with a powerful pump system that creates suction to draw the sewage into a tank mounted on the truck. The tank is designed to hold a large volume of liquid waste safely and securely during transportation.Isuzu sewage pump trucks are commonly used by municipalities, sanitation departments, and waste management companies to maintain and clean sewer systems, septic tanks, and other areas where liquid waste accumulates. They play a crucial role in maintaining public health and safety by preventing sewage backups and ensuring proper waste management.

1. Before inhaling the Isuzu sewage suction truck, prepare to close the rear door of the tank of the isuzu sewage suction truck and observe whether the lubricating oil of the vacuum pump oil and gas separator is normal.

2. Operation sequence:

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

b. Turn on the Isuzu sewage suction truck alarm switch in the cab.

c. 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).

d. 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.

e. Remove the sewage suction hose from the Isuzu sewage suction truck 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.

3. Precautions for suction operation of Isuzu sewage suction trucks:

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

b. 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. When inhaling sludge, the suction pipe should be moved frequently. When inhaling high-viscosity sludge, occasionally inhaling air and water can improve the pollution efficiency.

4.Method for discharging sewage from the sewage pumping truck: After the mud and water are separated, open the drainage ball valve, drain the sewage and repeat the suction of mud. You can also pressurize and drain quickly. The operation method is as follows:

a. 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.

b. Switch the four-way valve of the Isuzu sewage suction truck to the discharge position, and the vacuum pump continues to work, and the compressed air sewage flowing into the tank will be quickly discharged.

c. 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.

5. Sludge discharge method from Isuzu sewage suction truck:

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

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

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

d. Set the tank door opening and closing lever of the manual reversing valve of the sewage suction truck 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 seal will be damaged. rings and cylinders.

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

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

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

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

c. 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.
