The main features of the sewer truck are the use of cleaning and cleaning of urban pipelines and its sewer sediments, and dead mud clearance. It can also be used in other uses such as avoidance and drainage pipes in the cleaning industry. The sewage suction truck is a new type of sanitation cleaning vehicle that cleans and collects transportation sewage and sludge, and can avoid secondary pollution caused by the waste. Sewage suction vehicles are capable of self-discharge and self-priming. The capacity of work is relatively large, the speed is fast, and transportation is convenient. It is more suitable for transporting and collecting liquid materials such as crude oil, mud, and even feces. The vehicles used are the domestic leading suction pump vacuum pumps. The vacuum pump has the function of suction and suction, and it is suitable for the use of the loading, unloading and suction of the deposition objects in the sewer, especially those hidden in the sewers. Larger objects such as stones, mud, bricks, mud, etc.
Nowadays, the sanitation vehicle fleet of sewage suction vehicles is increasingly put into use in various cities. Then, in order to better understand new users' correct discharge of sewage, it is now for everyone to make A simple process understands:
1, Sewage truck preparation before work
(1) The rear part of the sewage suction truck should be as close as possible to the place where the operation is required.
(2) Turn the return tank straight until the cock rotates and the angle of about 45 degrees appears on the axis of the inlet pipe, and then observe the inlet pipe. At this time, the oil should begin to flow.
(3) Open the side door of the walkway box and take out the dirt suction hose so that it can swing back. The dirt suction hose cannot bend.
2. Sewage suction pump for suction work
(1) Draw the dirt-collecting hose as completely as possible into the liquid, and ensure that the port of the hose is always at a distance of less than 300 mm from the liquid surface during operation.
(2) Push the handle of the four-way valve straight to a position perpendicular to the ground.
(3) Hitch the vehicle's transmission to neutral, then turn on the engine, disconnect the clutch, and pull the switch of the power take-off directly to the catch-up force. The vacuum pump will start running immediately.
(4) Open the tool box in the cab, pull out the switch of the alarm, and turn on the power.
(5) The operator can observe through the observation lens on the upper part of the rear head. When the liquid level reaches the middle part of the observation lens, at this time, the driver should be informed in time, and at the same time it should be promptly Close the four-way valve or immediately pull the suction hose away from the ground. Under normal operating conditions, the sounder will emit audible and visual signals at this time. The driver should start to reduce the throttle after receiving the signal and push the power take off switch. Remove the gear until the vacuum pump stops running. Press the switch on the switch to turn off the power.
(6) Turn off the fuel tank directly through the cock and turn the handle into the mailbox parallel axis.
(7) Rinse the suction hose, place it in the walkway box, and close the side door so that the boom is facing the upper direction of the cab.
(8) Close the anti-overflow valve so that its axis and handle are vertical.
(9) Drive the sewer truck away from the operating point. Drive the sewer truck out of the work site.
3, sewage suction truck discharge work
(1) Put the dirt-collecting hose toward the storage tank.
(2) Pull the rear handle of the four-way valve straight down and parallel to the ground, and start the anti-overflow valve so that the handle and the axis of the pipeline are parallel.
(3) Hover the transmission to neutral, start the engine, disconnect the clutch, pull the switch to the riser like a dog, and the vacuum pump starts operating immediately.
(4) After the sewage liquid in the sewage tank is discharged, the driver should promptly push the power take-off handle forward until the vacuum pump stops operating.
(5) Close the fuel tank through the cock and turn the handle and parallel to the axis of the inlet tank. Rinse the suction hose cleanly, place it in the walkway box, and close the side door so that the boom is facing the upper direction of the cab.
(6) Sewage suction trucks leave the working point. (Text / Sun Ni)
