Preparation and precautions before using suction sewage truck

1, before the job is ready 
(1) sewage suction trucks operating point as close to the rear of the parking. 
(2) will return the tank to pull the handle straight cocks rotation axis of the intake pipe about 45 ° angle of observation into the pipeline, the lubricating oil should flow. 
(3) take the box-side door open, remove sewage suction hose, making it swing back, without bending phenomenon. 

2, the suction operation 
(1) The sewage suction hose pumped liquid sewage as deep as possible to ensure that the pipe end during the job and always below 300mm from the liquid surface. 
(2) the four-way valve handle to push perpendicular to the ground. 
(3) linked to the transmission into neutral and start the engine, disengage the clutch, the power take-gear switch is pulled back that is to take power, the vacuum pump starts running. 
(4) Open cab toolbox Xiangqi pull the switch, turn on the power. 
(5) After the operator through the head with the Ministry of mirrors, observe when the level reaches the middle of the mirror, the driver should be notified, shall promptly colleagues sewage suction hose pulled from the ground or off the four-way valve. Under normal circumstances, this time Xiangqi audible and visual signals, the driver receives a signal should reduce the throttle, the power take off switch forward shirk stall, pump stopped moving forward, according to the Xiangqi switch off the power . 
(6) The fuel tank straight cocks rotation axis parallel to the shank plate and into the mailbox is closed. 
(7) After rinsing hose, put it back down station box, shut the side door, and above the boom toward the cab. 
(8) close the spill valve, so that it can handle the road perpendicular to the axis. 
(9) suction sewage truck left the operating point. 

3, row Unloading 
(1) The sewage suction hose toward accumulating dirty pool. 
(2) the four-way valve handle to pull parallel to the ground, open the spill valve, so that it is parallel to the axis of the handle to the pipe. 
(3) linked to the transmission into neutral and start the engine, disengage the clutch, the power take-gear switch is pulled back that is to take power, the vacuum pump starts running, the transmission will be linked into neutral and start the engine, disengage the clutch, power take That switch-gear pull back power take off, the vacuum pump starts running. 
(4) after the tank body fluid discharge sewage emptied, the driver should be promptly handles power take off the file that is pushed forward, the vacuum pump is stopped. 
(5), the fuel tank straight cocks rotation axis parallel to the shank plate and into a mailbox that is closed, after rinsing hose, put it back down station box, shut the side door, and above the boom toward the cab. 
(6) the suction sewage truck left the operating point. 

Precautions: 
(1) to maintain a suitable number of revolutions of the vacuum pump. Pump speed too high, according to the rotor plus fever; speed is too low, causing the ship machine, the impact of additional components, affect life expectancy. In order to achieve optimum operating speed, in advance according to the best players to adjust the position of the accelerator pump. 
(2) in turn can dump on flat ground. Suction sewage truck with a lift dump system can discharge its own dump, so when the dump prohibit local jobs in uneven pavement or even inclined, the inclined road dump turn can produce distortion components will lead to failure, and It may cause a rollover accident. 
(3) Dump first turn can open when the tank after tank door. Dump dumping preceded turn can loosen the locking bolt, the rear tank door lifted to the required angle in the tank after ban lift the door off the tank when the tank is full, otherwise they will be after the center of gravity moved, the risk of rollover. 
(4) pumps and vacuum pumps PTO engine idling and fully Cairu clutch pedal, turn on the power take off slowly release the clutch pedal after the switch. 
(5) cars, vacuum pump and the pump is in the stop state. 
(6) Do not use suction sewage suction trucks and transporting waste oil and hazardous materials in order to avoid a serious accident fire or explosion. 
(7) Tipper turn can lift the state into the bottom of the tank or repair, you must use the support rods and safety stopper. 
(8) When transporting dirt, vehicles must be slow and medium-speed driving, braking and sharp turns can not be, because no anti-tank wave plate high center of gravity.
