Therefore, there are many varieties of sewage suction trucks. Users who need to purchase sewage suction trucks should directly contact the sewage suction truck manufacturers to obtain good configuration recommendations and preferential sewage suction truck prices.

Second, function

The special part of the sewage suction truck is composed of power take-off device, drive shaft, vacuum sewage pump, pressure tank, hydraulic part, pipe network system, vacuum pressure gauge, scat window, hand-washing device, etc. The vehicle is equipped with high-power vacuum suction. Pump and high-quality hydraulic system, one-time die-casting of tank head, tank opening, and double top dumping. The dirt in the tank can be dumped directly through the rear cover, with a high degree of vacuum (more suction than a suction truck), large tonnage, high efficiency, and a wider range of uses.

Third, composition

Oil-water separator, water and gas separator, hydraulic dumper, special vacuum suction pump, volume pressure gauge, suction tube, gravity valve, vacuum tank, connected device (stool window), automatic spill control valve, hydraulic kit .

Fourth, the scope of application

The sewage suction truck has the same principle as the suction truck, but the sewage suction truck has different uses with the suction truck. The difference lies in the fact that the suction truck body is a circular tank and has a tighter structure and can withstand higher pressures to provide greater suction. It can be used to collect and clean up the transportation sewage and sludge.

Fifth, the working principle

When the sewage suction truck is working, because the suction hose is always immersed on the liquid surface, the air in the waste tank is sucked and becomes thinner and thinner due to the lack of replenishment. As a result, the pressure in the tank is lower than the atmospheric pressure. That is, under atmospheric pressure, the suction hose enters the tank. 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.

Sewage suction vehicles have features such as 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.

The main purpose of sewage suction trucks:

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 for fire fighting in case of emergency. .

Six, choose

1. Pay attention to the quality of the plate, the vacuum sealing degree, and the poor material can easily cause problems such as deformation of the tank body.

2. The choice of vacuum kit, the pressure capacity and the perception of temperature difference.

3, After the choice of lid, according to the local operating environment, temperature and other choices.

4. According to the relevant provisions of the National Development and Reform Commission on the emission of the three exhaust gases of the enforcement countries, the National 2nd vehicle parameter data has been deleted since July 1, 2008. On January 1st, 15th, the National Sanwei Sewage Suppression Bulletin was all deleted. Sewage suction car users need to purchase the National IV Sewage Sewage Pump or the National Fifth Sewage Sewage Sewage Vehicle according to their local environmental protection policies.

Seven, user manual

1. Preparation before operation

(1) The rear part of the sewage suction truck should be as close as possible to the operating point and parked.

(2) Pull the return oil tank's straight cock rotating handle to the angle of about 45° with the axis of the oil inlet pipe. Observe the oil inlet pipe and there should be lubricating oil flow.

(3) Open the side door of the walk-in box and take out the dirt-absorbing rubber hose so that it swings back without bending.

2. Pumping operation

(1). Draw the sewage suction hose as deep as possible to ensure that the end of the pipe is 300mm below the liquid level during the operation.

(2) Push the four-way valve handle vertically to the ground.

(3). Hitch the transmission to neutral, then start the engine, disconnect the clutch, pull the power take-off switch backwards to pull the file, and the vacuum pump starts to run.

(4) Open the cabin tool box, pull out the alarm switch, and turn it on.

(5) The operator can pass through the observation mirror on the upper part of the rear head. When the liquid level reaches the middle of the observation mirror, the operator should be notified that the colleague should quickly pull the suction hose away from the ground or close the four-way valve. Under normal circumstances, the sounder will emit audible and visual signals at this time. When the driver receives the signal, the throttle should be reduced. The power take-off switch is pushed forward and the gear is removed. The vacuum pump stops moving and presses the switch to cut off the power. .

(6) Close the fuel tank straight cock rotating handle plate parallel to the axis of the incoming mailbox.

(7) After flushing the hose, place it back in the walkway box, close the side door, and position the boom over the cab.

(8) Close the anti-overflow valve so that the handle is perpendicular to the axis of the road.

(9) Drive the sewer truck away from the operating point.

3. Drainage operations

(1) Point the suction hose toward the reservoir.

(2) Pull the rear handle of the four-way valve parallel to the ground and open the spill-proof valve so that the handle and the pipe axis can be parallel.

(3) Hitch the transmission to neutral, start the engine again, disconnect the clutch, pull the power take-off switch backwards to pull the file, and the vacuum pump starts to run.

(4) After the discharge of the liquid in the tank, the driver should push the power take-off handle forward and remove the gear, and the vacuum pump stops running.

(5) After the fuel tank straight cock rotating handle plate is parallel with the axis of the e-mail box, it is closed, after the hose is rinsed,

(6) Move the sewer truck away from the operating point.

VIII. Operational matters

1) Keep the suction pump vacuum pump suitable rotation speed The vacuum pump speed is too high, the rotor heating plus data; the speed is too low, it will cause additional impact on the shipping machine, components, affecting life. In order to achieve a suitable working speed, please adjust the good position of the hand throttle in advance according to the pump type.

2) Self-unloading cans on flat ground;
The unloading of the tank on an inclined road surface will cause distortion of the components and cause failures, and it may cause roll-over accidents.

3) After opening the tank, open the tank after the tank door first:

Before releasing the mud from the unloading tank, the locking bolt should be loosened and the rear tank door should be lifted to the required angle. When the tank is full, it is forbidden to lift the tank body with the rear tank door closed. Otherwise, there is a risk of overturning.

4) When the oil pump and the vacuum pump take power, the engine idles, and fully steps on the clutch pedal. After opening the power take-off switch, slowly release the clutch pedal.

5) When the sewer truck is running, the vacuum pump and the oil pump are stopped.

6) Do not use a suction truck to inhale material larger than the hose diameter and to transport waste oil and hazardous materials.

7) The support rod and safety stop must be used when the unloading tank is lifted to enter the bottom of the tank or for maintenance.

8) When the sewage suction truck transports dirt, the vehicle must run at a medium speed and at a slow speed. It is not allowed to make sharp turn and sudden braking because the center of gravity of the anti-wave board is high.

Nine, maintenance matters

1: a reasonable determination of the maintenance cycle

Scientifically determining the interval between maintenance operations of various types can not only keep the car constantly in good technical condition, but also save some unnecessary troubles. New cars with good general automotive technology conditions can be properly prolonged and maintained when they are used under good operating conditions. However, if the condition of automotive technology is poor or the operating conditions are poor, the maintenance cycle should be appropriately shortened.

2: Take full advantage of free testing

Sewage vehicle owners can use these free testing activities to conduct a comprehensive physical examination of their vehicles, discover potential problems in a timely manner, and eliminate these hidden troubles, eliminating the need for unnecessary faults in the future.

3: Dismantle the maintenance assembly as little as possible

Many owners have this feeling that an assembly of their own car will be out of control after the dismantling and maintenance, and it will be “inpatient” treatment after some time. In order to prevent the vehicle from entering the maintenance period prematurely, you should dismantle the maintenance assembly as little as possible and use all kinds of advanced maintenance equipment and means to carry out the maintenance-free operation of the car. This will not only avoid the disassembly of the car assembly and components. Without unnecessary damage, the speed of car maintenance can be greatly accelerated, thereby reducing maintenance time.

4: Appropriate use of oil

The proper use of oil includes two aspects: First, fuel, and second, lubricating oil. Improper use of fuel can easily cause malfunctions such as clogging of the fuel filter, causing idling instability, poor acceleration, and increased fuel consumption, as well as accelerated cylinder wear and engine life. How to use lubricating oil, so that it can meet the lubrication requirements, but also improve the efficiency of the engine? The basic principle is: to meet the vehicle use requirements on the line, only choose a good fuel and lubricants. Such as engine oil, for domestic cars, some domestic SJ-class engine oil can fully meet the requirements, there is no need to choose to import.

5: Sewage suction vacuum pump accessories: oil-water separator

The hydraulic oil separated from the oil-water separator of the sewage suction truck will be used as the vacuum pump lubricant for the vacuum pump. However, the water left behind will be stored at the bottom of the tank. Therefore, the sewage suction truck must be drained after completing the work. Forgetful drainage will be sucked into the pump. Caused by sintering and other problems, the use of hydraulic oil is too long, will reduce the smoothness and air tightness. Therefore, the sewage truck should replace the hydraulic oil on schedule.

6: Sewage pump anti-overflow valve

Sewage Pump Anti-Stop Valve It is installed in case the tank overflows to prevent the sewage from overflowing into the vacuum pump of the suction pump. If the suction pump suctions more sludge, the vacuum pump can easily be damaged. Therefore, when the sewage suction truck works, it is necessary to frequently check the quality of the spill-proof valves.

7: Sewage suction tank door

After the long-term operation of the tank door after the sewage suction truck has been installed, internal dirt will occur and the handwheel must not be tightened. Therefore, the interior should be divided and cleaned every 6 months. At this time, smooth grease should be properly added. After the sewage suction truck is working, it is better to clean the sealing rubber ring of the tank door. If there is a leakage, if there is no problem in the inspection and tightening device, it is necessary to replace the sealing rubber ring of the suction tanker tank door, and the suction tanker tank door sealant If the ring is used for a long time, the tightness may decrease.

Ten, cleaning method

1, first of all pay attention to the frequency of car wash, not too frequent, so it is easy to damage the sewage suction car paint.

2. Clean water should be used when washing the car, otherwise the fine sand in the sewage will be wiped with float paint. If the temperature in winter is relatively low, it should be cleaned with warm water.

3, to use a clean special car wash towel, the general friction of the towel is strong, it is easy to damage the sewage suction car paint, especially after the winter car wash immediately wipe the body of water in order to avoid residual icing on Damaged paint.

4. Car wash should be carried out in a cool and cool place. In winter, you can wash your car under sunlight.

5, in the car wash should pay attention to do some of the components of the sewage suction truck waterproof work, such as speakers, lights, door lock holes, etc., in order to avoid the failure of the horn, fog lights or winter door lock hole water after the ice door lock will not open .

6. Do not wash the vehicle immediately after the sewage suction truck has been driven in winter. Wait until the engine temperature of the suction pump drops down before proceeding with the car wash so as not to damage the engine due to thermal expansion and contraction.

XI. Undercarriage

Travel system, brake system, steering system, transmission system

The special part of the sewage suction truck is composed of power take-off device, drive shaft, vacuum sewage pump, pressure tank, hydraulic part, pipe network system, vacuum pressure gauge, scat window, hand-washing device, etc. The vehicle is equipped with high-power vacuum suction. Pump and high-quality hydraulic system, one-time die-casting of tank head, tank opening, and double top dumping. The dirt in the tank can be dumped directly through the rear cover, with a high degree of vacuum (more suction than a suction truck), large tonnage, high efficiency, and a wider range of uses.
