Dongfeng pointed vacuum suction truck
Introduction
Dongfeng Tip Vacuum Sewage Sucker: The special part consists of vacuum suction pump, power take-off device, drive shaft, water and gas separator, oil and gas separator, multi-way reversing valve, tank, blowdown valve, sewage window, vacuum Pressure gauge, pipe network system, hydraulic system and other components. The tank head is die-cast, the tank body can be opened afterwards, and the double roof can be unloaded. The suction truck can be self-priming and self-priming. The suction suction truck has all the functions of the suction truck and has higher vacuum than the suction truck. Longer suction, greater pressure, higher tonnage, higher efficiency, and wider use.
1. The installed vacuum pump has enough suction vacuum and long service life.
2. Set secondary protection for the vacuum pump to prevent contamination from seeping into the pump body.
3, hydraulic pump and vacuum pump work in a step-by-step manner, reliable performance.
4. With hydraulic lifting and dumping function, it is easy to dump various sludges.
5. The hydraulic pressure of the rear tank door is automatically opened to facilitate the cleaning of sediments and solidification in the tank.
Operating procedures 1, the vacuum pump speed is too high, the rotor heat increases; the speed is too low, it will cause the engine knock, parts cause additional shocks, affecting life. Appropriate operating speed, pre-adjusted engine speed. The pump speed is 500-600 rpm.
2. Turning the tank on a flat ground The tilting of the tank on an inclined road surface not only causes distortion of the components and causes failure, but also may cause a roll-over accident.
3, turn the tank, please open the back cover before turning the tank to open the back cover to open the mud, should not close the lid after the closure of the tank, due to the center of gravity back to the risk of overturning.
4. Power take-off operation: Adopt the Dongfeng series power take-off device, pneumatic operation, use the lower clutch, operate the switch to pull back, easy clutch, take the force tooth into the meshing position, drive the vacuum pump and hydraulic oil pump through the drive shaft; Pedal down the clutch, the switch back to the position, take the force separation, vacuum pump and hydraulic pump to stop working.
5. Pay special attention when driving the car: The power take off switch must be in the closed position.
6. Do not use this vehicle to inhale and transport waste oil and dangerous materials.
7. When lifting the can body into the bottom of the tank or during overhaul, support bars and safety baffles must be used.
8. When transporting liquids, the rear cover clamping device must be used. Because there is no anti-wave plate in the tank and the center of gravity is high, the vehicle must be driven at a moderate speed and a slow speed. Do not make sharp turns and sudden braking.
Job Notes 1. The impurities such as stones, cotton yarn, and leaves larger than 50mm will block the hose, so they cannot be inhaled and should be removed regularly.
2. Observe the vacuum gauge reading to 65-80 kPa, fully open the suction ball valve, and the semi-open state will easily damage the valve core.
3, inhalation of sludge into the rate, should always move the hose, when inhaling high-slurry sludge, occasionally inhaled air and water, can reduce pollution efficiency.
Job 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 or less from the liquid surface during the operation.
(2) Push the four-way valve handle perpendicular to the ground.
(3) Hitch the transmission to neutral, then start the engine, disengage 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) Put the transmission into neutral again, start the engine, disengage 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) Close the fuel tank straight cock rotating handle plate and enter the axis of the e-mail box and close it. After the hose is rinsed, put it back into the walk-in box, close the side door, and make the suspender point towards the cab.
(6) Move the sewer truck away from the operating point.
