Sewage suction trucks are sanitation vehicles that collect, transfer, and transport sludge, sewage, etc. Sewage suction vehicles are more powerful than suction trucks and have a wider range of applications. Its fast working speed, convenient transportation, large capacity, and transport medium involve the characteristics of most liquid substances such as excrement, mud, crude oil, etc., and are loved by many environmental protection companies and sanitation. The sewage suction trucks on the market today are equipped with powerful vacuum pumps. They have a large suction force and a long suction range. They are suitable for the suction and shipment of sludge in sewers. They are also very useful for mud, gravel, bricks and other debris in sewers. Good results. The main purpose of a sewage suction truck is to dredge sediments and dead mud in urban sewers, pipelines, and also to clean pipeline walls. The purpose of a sewage suction truck is not unique. Sometimes it can also be used as a sprinkler. It can also be used as a fire truck in an emergency. The sewage suction truck works by using the principle of atmospheric pressure to pump sewage. Place the suction pipe of the suction truck on the liquid surface, and use a suction pump to suck the air in the tank clean. Then the pressure in the tank is much lower than the atmospheric pressure. Sewage under the influence of atmospheric pressure, through the sewage pipe into the pipe. The fouling principle is similar to that of suction. The air is pumped by a suction pump into a tank. The pressure in the tank is greater than the atmospheric pressure. The sewage in the tank enters the sewage discharge pipe under the pressure of the tank and is excluded from the tank. Sewage suction vehicles have high suction efficiency, self-priming, self-discharging, direct irrigation, long service life, high working speed, convenient transportation and simple operation. When choosing a sewage suction truck , pay attention to the quality of the tank and the degree of sealing. If you do not pay attention to the above problems, it will lead to deformation of the tank. The selection of accessories such as suction pumps should pay attention to the ability to withstand pressure and the perception of temperature differences. In addition, China has already enforced the country's three standards for the discharge standards of sewage trucks. The friend who is ready to buy a car should pay attention to the purchase of the cleaner vehicle manufacturer. The above is a brief introduction to Xiao Bian's use of sewage suction trucks, working principles, and selection criteria. If you still have problems, you can contact our staff.

The cold rolling mill is an advanced equipment that continuously rolls blades from strip steel. By adjusting the position (roll offset, feed height, roll pressure, guide wheel, etc.), it can roll out blades of various specifications required.
Advantages of cold rolling layout:
It has the advantages of high production efficiency, saving raw materials, good blade quality, high hole diameter, and good wear resistance.
The structures that affect the rolling shape include the material and thickness of the strip, the offset of the roll, the feeding height, the rolling force of the roll, the different specifications of the guide wheels and blades, and the increase in the temperature of the roll during the rolling process. After years of construction, the contract developed this continuous cold-rolled propeller, which has the advantages of smooth surface, high hardness, wear resistance, one-time forming, and continuous no welds.
