In many cases, users have overlooked a problem that is to properly operate your suction truck and do not operate in violation of the regulations, so as to make your suction truck last longer.
Common problems are as follows: First, we must understand the working principle of suction truck vacuum pump. The more important work principle is the consideration of the source of power and stability. The vacuum pump power comes from the chassis engine. The engine is transmitted to the vacuum pump via gearboxes, power take-offs and driveshafts. During the suction operation, the vacuum pump extracts the air in the sealed tank to form a negative pressure. The atmospheric pressure outside the tank is used to press the dirt into the tank through the suction pipe. When the sewage is drained, the vacuum pump will put atmospheric pressure outside the tank into the tank and use the air pressure to discharge the dirt out of the tank (the vacuum pump's continuous working time generally does not exceed 30 minutes). The flow sequence of the air flow in the air path is as follows: When the air is sucked, the vacuum pump sucks the air with a certain humidity in the tank into the water and gas separator, where the water is separated and flows back into the tank. The gas enters the vacuum pump along the pipeline through the four-way valve. Air intake. The pump is mixed with the lubricating oil and is discharged from the exhaust port through the compression chamber. In particular, the mixture is initially separated by the primary filter, and the separated oil flows back to the oil pump. The mixture is further separated by an oil separator and then discharged into the atmosphere through a four-way valve. Manual operation of the four-way valve can change the direction of the air flow, sucking and discharging freely. When the vacuum pump of the suction truck is completed, it is necessary to formulate a corresponding inspection of the suction truck according to the different working intensity of each time, so as to ensure the working life of the suction truck and the second working efficiency.
In fact, the suction truck is not as mysterious as everybody thinks. I still hope that the user will understand the structure of the suction truck so that when some simple problems are discovered, it can be immediately solved, thereby reducing the user's loss due to faults.
