1. Preparation before operation (1) The rear of the suction truck should be as close as possible to the operating point and parked. (3) Open the side door of the walk-in box, remove the suction hose, and swing it back without bending. 2. Pumping operation (1). The suction hose should be as deep as possible into the feces to ensure that the pipe end is always 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 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 pass the observation mirror on the upper part of the rear head. When the liquid level reaches the middle of the sight glass, the operator should be notified that the coworker 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. . (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. (9) Close the anti-overflow valve so that its handle is perpendicular to the axis of the road. (10) Move the suction truck away from the operating point. 3. Drainage operations (1) Move the suction hose towards the storage tank. (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, then start the engine, disconnect the clutch, pull the power take-off switch backwards to pull the file, take the power, start the vacuum pump, put the transmission into neutral, then start the engine, separate the clutch, and take the power. The switch pulls back and pulls the file, and the vacuum pump starts to operate. (4) After the discharge of the fecal fluid in the tank, the driver shall promptly push the power take-off handle forward to remove the gear, and the vacuum pump will stop 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 suction truck away from the operating point. This large-scale rural area is not suitable for use in rural areas. Therefore, it is not suitable for rural use of three-wheeled slag-retarding vehicles. Handheld Laser Welding Machine Better weld formation: YIHONG or STARTNOW welding head,Swing welding mode, spot width can be adjusted, welding fault tolerance is strong, make up for the disadvantage of laser welding spot small, expand the tolerance range of machining parts and weld width, get better weld forming.

The suction truck (2) pulls the return tank straight through the cock rotating handle to the angle of about 45° with the axis of the inlet pipe. Observe the oil inlet pipe and the oil flow should occur.
Adjustable width, can have certain penetration to thick plate, suitable for fillet welding,
It is used for weld and wire feed welding
Adjustable diameter, uniform energy density distribution, It has obvious advantages when welding the high frequency thin plate.
Can adjust the diameter size, the main effect is to reduce the hollow spot to make the spot largerr ,which makes the plate more evenly exposed to light radiation, which is suitable for welding at various angles
Adjustable width, while reducing the hollow of the spot, the energy of 3 sides can make the board;The middle and left and right sides of the material are fully heated, and the frequency can be reduced when adding wire feed welding.When the rate is lowered, the welding spot can appear as fish scales, compared with single swing welding.The joint effect is remarkable

User guide
Easy to learn and easy to operate: The operation is simple, and the welding methods of different forms of joints can be realized.
Fast welding speed: The welding speed is fast, 2-10 times faster than traditional welding, and one machine can save at least 2 welders a year. Laser welding has less consumables, longer life, safer and more environmentally friendly.
Small spot, strong energy, suitable for penetrating welding and cutting
