PTO, drive vacuum pump, and hydraulic oil pump.

Hydraulic Oil Pump, drive hydraulic oil to open the back cover and lift the suction tank.

Hydraulic Cylinder, hydraulic opening, four-point hydraulic locking, hydraulic cylinder lifts the tank by 46°, electro-hydraulic opening, and closing of the tank, hydraulic locking is linked with the opening and closing of the tank door, and the tank door is rubber sealed.

Use an electrical integrated control manifold valve to effectively avoid electrical failure.

Vacuum Pump: Italy vacuum pump, the rotary vane type all-steel series vacuum pump adopts a high temperature resistant mechanical oil seal, which is suitable for high-temperature working conditions. The exhaust port adopts a flexible pressure adjustment system, which effectively reduces the noise. The oil leakage detection hole of the oil seal can effectively prevent oil leakage.

Primary Shutoff: Cylindrical shape with multi-layer partitions inside. When the oil-air mixture enters from the air inlet, it flows through the multi-layer plates. The specific gravity of the gas and the lubricating oil are different. The gas flows into the air outlet along the channel, and the separated oil is used again as the lubricating oil of the vacuum pump.

Secondary Shutoff: Cylindrical shape, there is a split baffle in the inlet, and a sealing ring and stainless steel ball are installed. When the water-gas mixture enters the water-gas separator from the tank, due to the difference in specific gravity between the water and the gas, the gas is discharged from the air outlet, and the water is dropped into the water-gas separator. The lower part of the water-gas separator. It is installed on the top of the large tank of the vacuum suction truck and is connected to the suction port of the pump. Its function is to push the one-way valve to the suction port of the device due to the action of the float when the suction tank is almost full and close the suction port under the combined action of the float and the vacuum suction, effectively preventing the sewage and floating objects in the large tank from being damaged the suction vacuum pump line and vacuum pump. A vacuum pressure gauge is used to detect the pressure in the tank. Water and sewage exchange, connect the water tank and the sewage tank, the sewage tank can be used as a water tank.

DN100 ball valve, the ball valve on the sewage suction truck is used for sewage pumping, and its material is generally aluminum alloy. The DN150 ball valve, the ball valve on the sewage suction truck is used for sewage self-draining, and its material is generally aluminum alloy. A fire Hydrant Interface is used to fill the water of the tank. A sewage Observation Window is used to detect the sewage water level in the tank.

Toolbox, for storing tools 6MM thick carbon steel plate, anti-corrosion treatment. The multi-way valve of the Sino-foreign joint venture is adopted, which is small in size, large in diameter, and balanced in force. The piston inside the multi-way valve is wear-resistant and durable. The tank is made of a national standard Q235 carbon steel plate, with strong pressure resistance, corrosion resistance, and durability, and test reports can be provided at any time.

Installed on the top of the tank to prevent dirt from entering the vacuum pump pipeline and vacuum pump when the tank is full.
