Sewage suction truck : the special part of the sewage suction truck consists of power take-off, transmission shaft, vacuum sewage pump, pressure tank, hydraulic part, pipe network system, vacuum pressure gauge, manure window, hand washing device, etc. Power vacuum suction pump and high-quality hydraulic system, the tank head is die-casted at one time, the tank can be opened back, and the double top is self-unloading. The dirt in the tank can be directly dumped through the back cover, which has the characteristics of high vacuum (larger suction power than the suction truck), large tonnage, high efficiency and wider use.
Manure suction truck: The manure suction truck is mainly applied to special vehicles for cleaning and cleaning under the environment of septic tanks, sewage ditches and sewers, etc. , as well as sprinklers and garbage trucks , and is called the three major sanitation models.
Sewage suction trucks and suction trucks have the same principle, but sewage suction trucks and suction trucks have different uses. The difference is that the tank body of the sewage suction truck is a round tank, which has a more compact structure, can withstand higher pressure and provide greater suction, and can be used to collect and clean sewage and sludge.
The working principle of sewage suction truck:
Because the suction hose is always immersed in the liquid surface, the air in the feces tank is sucked and becomes thinner and thinner because it cannot be replenished, so that the pressure in the tank is lower than the atmospheric pressure, and the fecal liquid is used under atmospheric pressure , Into the container via the suction hose. Or because the siphon is close to the bottom of the tank, and the air is continuously discharged into the manure tank, it is compressed because it has no way out, so that the pressure in the tank is higher than the atmospheric pressure, and the manure liquid is discharged through the siphon and the suction hose under the action of compressed air Outside the tank.
Sewage suction truck has the characteristics of high suction efficiency, self-priming, self-draining and direct irrigation. Time to pump the dung tank: ≤5min, suction stroke: ≥8m. It has the characteristics of long service life, fast working speed, easy operation and convenient transportation.
The working principle of sewage suction truck:
1. Preparation before homework
â‘´ The rear of the sewage suction truck should be as close as possible to the operating point and parked.
⑵ Pull the straight-through cock of the return tank to an angle of about 45 ° with the axis of the oil inlet pipe. Observe the oil inlet pipe, and there should be lubricating oil flowing.
(3) Open the side door of the walking platform box, take out the suction hose and make it swing backward without bending.
2. Suction operation
â‘´. Suck the suction hose as deep as possible into the liquid to ensure that the pipe end is always less than 300mm from the liquid surface during the operation.
⑵. Push the four-way valve handle perpendicular to the ground.
⑶. Put the transmission into neutral, then start the engine, disengage the clutch, pull the power take-off switch backward to take power, and the vacuum pump starts to run.
â‘·Open the toolbox in the cab, pull out the sounder switch, and turn on its power.
⑸The 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. Colleagues should quickly pull the suction hose off the ground or close the four-way valve. Under normal circumstances, the buzzer will emit a sound and light signal. The driver should reduce the throttle when receiving the signal, push the power take-off switch forward and out of gear, the vacuum pump stops rotating, press the buzzer switch, and cut off its power supply .
⑹Close the refueling tank straight plug cock handle plate parallel to the axis of the incoming mailbox.
⑺After rinsing the hose, put it back in the platform box, close the side door, and make the boom point upwards of the cab.
â‘»Close the anti-overflow valve so that its handle is perpendicular to the axis of the road.
⑼ Drive the sewage suction truck away from the operating point.
3. Discharge operations
(1) Orient the suction hose to the reservoir.
⑵ Pull the rear handle of the four-way valve parallel to the ground, open the anti-overflow valve, and make the handle parallel to the axis of the pipeline.
(3) Put the transmission into neutral, start the engine again, disengage the clutch, pull the power take-off switch backward to take power, and the vacuum pump starts to run.
â‘· After draining the tank, the driver should push the power take-off handle forward to release the gear, and the vacuum pump stops.
⑸ Close the refueling tank straight plug cock handle plate parallel to the axis of the incoming mailbox, after flushing the hose,
⑹ Drive the suction truck away from the operating point.
The working principle of the suction truck:
(2) Turn the straight plug cock of the oil return tank to an angle of about 45 ° with the axis of the oil inlet pipe. Observe the oil inlet pipe, and there should be lubricating oil flowing.
(3) Open the side door of the walking platform box, take out the fecal suction hose, and make it swing backward without bending.
Discharge
(1) Orient the suction hose to the storage tank.
(2) Pull the rear handle of the four-way valve parallel to the ground, open the anti-overflow valve, and make the handle parallel to the axis of the pipeline.
(3) Put the transmission into neutral, then start the engine, disengage the clutch, pull the power take-off switch backward to take power, and the vacuum pump starts to run.
(4) After the excrement in the tank has been discharged, the driver should push the power take-off handle forward to release the gear in time, and the vacuum pump stops.
(5) Close the fuel tank straight plug cock handle plate parallel to the axis of the incoming mailbox. After rinsing the hose, put it back in the box, close the side door, and make the boom point upwards of the cab.
(6) Drive the fecal suction truck away from the operating point.
This large-scale unsuitable for rural use cannot enter the farmyard, so it is not suitable for rural use of three-wheel slag pump
