Sewage suction car suction pump works principle and precautions

Sewage suction car suction pump works principle and precautions

1. Because the suction hose of the suction truck of the suction truck is always submerged under the liquid surface, the air in the waste tank is sucked and becomes thinner as it is not supplemented. As a result, the pressure in the tank is lower than the atmospheric pressure. The fecal fluid is used under atmospheric pressure and enters the holding tank through the suction hose. Or because the siphon tube is close to the bottom of the tank, when the air is continuously discharged into the manure tank, it is compressed because it has no way out. As a result, the pressure in the tank is higher than the atmospheric pressure. The manure fluid is discharged through the siphon tube and the suction hose under the action of the compressed air. Outside the tank.

2. Sewage suction truck features high suction efficiency, self-priming, self-discharging, and direct irrigation. Filling the manure tank time: ≤ 5min, suction process: ≥ 8m. According to the characteristics of long service life, fast working speed, easy operation and convenient transportation.

3. Sewage suction trucks are mainly used to clean city sewers, pipeline sediments, dredging of dead mud, can also be used to clean industrial drainage pipelines, walls, etc., and can also be used for watering, transporting water and highways, and can be used in emergencies. For firefighting.

When using a sewage truck, pay attention to some matters

1. Maintain the vacuum pump's suitable speed of the suction pump. If the speed of the vacuum pump is too high, the rotor will heat up and the speed is too low, it will cause the engine knocking, the components will cause additional impact, affect the service life, and the suitable working speed. Pre-adjust the throttle's large adjustment position.

2. Sewage suction trucks turn tanks on unsophisticated roads: Turning tanks on sloping roads will not only cause distortions in the components but also cause roll-over accidents.

3. When the sewage suction truck turns the tank, open the rear door and window firstly. Before the dumping tank dumps the mud, open the rear door cover. Remember to close the door and turn the tank. There is danger of overturning due to gravity shift.

4. When the suction truck suction pump is used to separate the clutch pump and the vacuum pump, the engine idles and fully steps on the clutch pedal. When clutching, the clutch pedal must be raised slowly.

5. Special attention should be paid to the suction truck driving the suction truck: The power lever is placed in the middle position, ie the power take-off is closed.
6. Under normal circumstances, it is not allowed to inhale and transport waste oil and dangerous goods by suction trucks.

7. When accessing the bottom of the tank in the state of lifting the tank of the suction truck, it is necessary to use the support to press the planned safety stop.

8. When sewage suction trucks transport sewage, they must use the rear door leaf clamping device. Because there is no anti-wave plate in the tank and the center of gravity is high, the vehicle must maintain a medium speed and a slow speed, without sharp turn and sudden braking.
