Respected User:

Thank you for choosing the series of vacuum suction trucks produced by the company!

The series of vacuum suction vehicles produced by our company use domestic high-quality second-class automotive chassis. It applies to urban sewer dredging, sludge clearance and other suction operations. This vehicle has sufficient suction vacuum, high tonnage, high efficiency, wide use, is suitable for large, medium, small urban, sanitation and industrial and mining enterprises, property, life, production drainage work.

How to make your newly purchased vacuum suction cars extend the service life and get the best benefits, is our goal together! But to a large extent, you depends on your proper use and maintenance of the car. To this end, we sincerely hope that you will read this manual in advance before using the car and keep it safe.

Product Description

In the use of national six-discharge chassis, the can body is made of Q235 high-quality steel plate, the can body is 6mm thick, the head is 6mm thick, but the butterfly head, the head is largely mechanical automatic welding. With Hangzhou Weilong high-power double vacuum pump, can body can be hydraulically lift, the rear cover can be opened, and the tail tail belts a self-export.

First, the main structure and principle

The main structure can be divided into: two types of automotive chassis, tank assembly, hydraulic system, pipeline system, separator device, electrical system, protective device, etc. The chassis adopts the domestically configurable Class Second Class Class Class Class Class Class Class Class Class Class Class Class Class Class Class Class Class Class Class Class Class Class 2 This specification mainly introduces the contents of the modified portion.

The can body is generally straight horizontal can, and the front and rear head is an elliptical head. The rear end head is welded to the flange. The flange is equipped with a sealing strip, the rear cover is hinged, and the rear cover is hinged. Cylinder telescopic and switches. The lower part is locked by the locking device. Tank weld has several flaking plates, and the intermediate position under the panel has a semi-circular vias. To alleviate the impact of the tank and improve the rigidity of the tank. The can body is welded with high quality carbon structural steel. It is used to select stainless steel or other non-ferrous metal tanks as needed.

The lower beam is welded with a U-shaped bolt seat, and the U-shaped bolt and the connecting plate are fixed on the car chassis body beam. The lower beam is equipped with a rubber plate between the chassis body beam, which acts as a shock absorption and noise.

1, anti-overvalue

The defense valve is usually used to be equipped with a sewage vehicle, which is a float unidirectional valve device, attached to the top of the large canister, and the pump admixture is connected. Its action is full of suction When the can, the suction port is turned off under the coincidence of the one-way valve top toward the suction port of the unidirectional valve, in the joint of the pinch and vacuum suction. Effectively prevent sewage and dirt of large cans from suck in vacuum pump line and vacuum pump.

2, separator

The separator used in the suction car is generally divided into a water vapor separator, an oil and gas separator, and a primary separator. When the vacuum pump works, the flow of the gas stream in the air path is: the air with a certain humidity in the can, first enter the water gas separator, here, the water is separated, flowing back, the gas along the airway pipe The four-way valve reaches the vacuum pump inlet gas, the gas is mixed in the pump and the lubricant of the pump, and the pump is ejected from the exhaust port in the compression chamber, the oil and gas mixing and the factor are preliminarily separated, and the separated oil flows back The fuel tank, mixed gas is further separated by the primary separator, then enter the four-way valve, and finally discharged into the atmosphere.

3, vacuum pump

The vacuum pump is driven by this vehicle, the air in the can body is pumped into a certain vacuum, and the can form a negative pressure, feces, sewage, and slurry such as a tank to achieve the purpose of harvesting transportation in the pipe automatic suction tank.

The vacuum pump is mainly composed of a pump body, a rotor and a shaft assembly, a plug, a slider, a slip ring, a bearing and a sealing device. When the eccentric rotor is rotated, the rotary piece is slid in the inner wall of the pump under the action of centrifugation, and the volume of the suction stud chamber gradually increases, and the gas is inhaled, until the rotary piece is turned to the end of the inhalation, the inhalation gas is isolated . The rotor continues to rotate, and the isolation gas is gradually compressed, the pressure is increased, and when the pressure exceeds the pressure of the exhaust port, the gas is discharged outside the pump. This repeatedly cycles, and pump the air in the container to form a vacuum. (Vacuum pump continuous working time should not exceed 30 minutes)

4, hydraulic cylinder

The hydraulic cylinder is a hydraulic execution element that converts hydraulic energy into mechanical energy, linear reciprocating (or swing moving). It has a simple structure and is reliable. When using it to achieve reciprocating, it is possible to avoid the deceleration device, and there is no transmission gap, and the movement is stable, so it is widely used in the hydraulic system of various machinery. The hydraulic cylinder output force and the effective area of the piston are proportional to the differential differences; the hydraulic cylinder is substantially consisting of the cylinder head, the piston and the piston rod, the sealing device, the buffer device, and the exhaust device. The buffer device and the exhaust device depend on the specific application, and other devices are essential.

5, striker

The driving force of the engine gearbox is taken out by the striker, transmitted to the boot box on the pump via the drive shaft, thereby driving the pump to achieve the setting function. The power manipulation of our factory uses pneumatic manipulation, ie, using a switch in the cab, which realizes the traffic control of the air path to achieve the output of power.

Pressure does not take force

If the striker does not take force, you need to check whether the small pass shaft of the strip is rotated. If you don't turn, you have to check the trachea of the Power Switch here. If you don't fall off, you should take the trachea of the striker. Next, then pull down the handbrake, is there any gas? If there is no gas, you have to completely check the trachea; if there is a gas stream, you need to remove the power (below, the specific operation of the video and sales manager), remove the finger's O-ring:

6, ball valve

The ball valve is composed of a valve body adjusted seat, a seal ring, a sphere, a valve stem handle, and the like, and the switch is 90 ° to realize the switch of the ball valve, and the ball valve is tightened to rotary to achieve the requirements.

7, hydraulic oil pump

The hydraulic oil pump is composed of a pump body, a rectangular tank, a pressure bar, an ultra-high pressure steel wire, a power component of a hydraulic system, which is a mechanical energy to convert the mechanical energy of the original motivation into a liquid, refers to a hydraulic system. It provides power to the entire hydraulic system. The hydraulic oil pump is the power source in the hydraulic system. We should meet the hydraulic system to meet the needs of pressure and flow in the selected hydraulic oil pump, but also fully considering the reliability, life, maintenance, etc. to select the hydraulic oil pump in the hydraulic system. Medium and long run.
