Sewage suction trucks are new type of sanitation vehicles that can collect, transfer and transport sludge and sewage, and can effectively prevent secondary pollution. The dirt in the tank can be dumped directly, which not only has high work efficiency but also has large capacity. Therefore, it is widely used to collect liquid substances such as manure, mud, and crude oil. Let's introduce Xiaobian about Futian Sewage Suck Truck and Futian Sewage Sewage Pump Operation Process and matters needing attention when using it. Workflow (1) Draw the sewage hose as deep as possible into the manure, and ensure that the pipe end is always within 300mm from the liquid surface during the operation. (2) Push the four-way valve handle of the suction truck to keep it perpendicular to the ground. (3) Suspend the sewer car's transmission into 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 should pay attention to monitoring the situation near the entrance of the suction hose, and use appropriate tools to block the debris so as to avoid blocking. (6) The operator can observe the upper mirror of the rear head. When the liquid level reaches the middle of the sight glass, the operator should be informed. At the same time, the suction hose should be quickly pulled off the ground or the four-way valve should be closed. 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. . (7) Close the filling tank through the cock rotating plate and enter the axis of the mailbox. (8) After flushing the hose, place it back in the walkway box, close the side door, and place the boom over the cab. Close the anti-overflow valve so that its handle is perpendicular to the axis of the road. (9) Drive the sewer truck away from the operating point. Precautions 1. To ensure the tightness of the pipeline, there can be no leakage phenomenon, otherwise the sewage suction truck will not be able to work. 2. The vats of sewage suction trucks must be installed with spill-prevention devices. Otherwise, when the sewage suction trucks are used, it is easy to suck the sewage into the vacuum pump and damage the entire system. 3. The oil return port of the primary oil-gas separator of the sewage suction truck must be connected to the oil return port of the secondary oil-gas separator and the oil suction pipe must be a rigid pipe or a hard oil-resistant rubber pipe (steel wire braided hose). It is not allowed to use heat-deformed plastic pipes. . 4. When using the new pump, the sewage suction truck should directly add 1-2L mechanical oil No.32 to the pump, and add 32# refrigerating machine oil when it is used in the cold regions of northeast and northwest. The above is about the work flow and the precautions when using the Futian Sewage Sewage Vehicle . Only the correct use can extend the service life.
