In many cases, users have overlooked a problem that is, the correct operation of suction trucks, do not operate in violation of the rules, so that your suction truck can last long without problems.
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.
UV Cureable Resin English name :UV Cureable Resin. Uv cureable resin contains active functional groups, which can be triggered by light initiator polymerization reaction under UV irradiation to generate three-dimensional cross network lattice solid. In combination with reinforced fibers, photocured composites can be made.
It can basically be described as a matrix reinforced laminated sheet formed by a synergistic combination of different filler materials and matrix components. Matrix resin is the basis of composite materials. Choosing the right matrix resin for different applications is very important, as it is about whether the material can provide a long-term solution. The matrix resin is a high quality epoxy vinyl ester resin with a proven history of many years of application in extreme environments, shipbuilding and FRP piping.
Some manufacturers may dilute their resins, but according to our research, low quality resins can cause the coating to age quickly underground.
