Development Trend of Sweeper in China
The sweeper industry in China has been developing for more than a decade. From the previous pure sweeping development to the current multi-module type, the performance and product quality of the products have also improved. After the reform and opening up, China began to import key outsourcing parts, which greatly improved the performance and reliability of garbage trucks. However, compared with many developed countries, there are still some gaps in the level of road sweepers in China, especially the reliability of products.
In order to improve the level of road sweepers in China, reduce the gap with other developed countries as soon as possible, and meet the needs of China's urban sanitation, manufacturers of road sweepers should choose a suitable direction for development. With the development and progress of our country's society, the city is not satisfied with a simple suction wagon. It will put forward more requirements in terms of multifunctionality, environmental protection, and economy. The market needs vacuum cleaners that can meet various needs.
As one of the city's major sanitation equipment, road sweepers can be widely used in the cleaning of roads, municipal sanitation, airport runways, and urban residential roads. The road sweeper can not only clean the road and recycle the garbage, but also can purify the air on the urban road. On the one hand, it ensures the beauty of the road and maintains the sanitation of the environment. On the other hand, it also maintains the road conditions of the road. Effectively reducing the incidence of traffic accidents further extends the life of the road. The use of road sweepers to clean and maintain roads in major cities in China has become a trend and fashion.
The road sweeper is a sanitation vehicle equipped with a cleaning system such as a sweeper brush and a suction cup. It assists the sanitation department of large and medium-sized cities in cleaning. The sweeper truck greatly reduces the work intensity of the sanitation workers and improves the work efficiency of the sanitation department. Effectively less secondary pollution such as dust occurs. China should increase the technological content of products and ensure its stability through various means on the basis of existing sweepers. Put more funds and manpower to develop new road sweepers. I believe that in the future, China's road sweeper technology will make greater breakthroughs. (Wen/Jun Xun)
Pneumatic ball valve is a ball valve equipped with a pneumatic actuator. The execution speed of the pneumatic actuator is relatively fast. The fastest switching speed is 0.05 seconds / time, so it is usually also called pneumatic quick cut-off ball valve. Pneumatic ball valve is usually equipped with various accessories, such as solenoid valve, air source treatment triplet, limit switch, positioner, control box, etc., to realize local control and remote centralized control. The valve can be controlled in the control room without running to the site or high altitude and dangerous areas for manual control, which saves human resources, time and safety to a great extent.
The pneumatic ball valve can be closed tightly only by using the pneumatic actuator to rotate 90 degrees with the air source and a small rotating torque. The completely equal inner cavity of the valve body provides a very small resistance and straight flow channel for the medium. It is generally considered that the ball valve is most suitable for direct opening and closing. The main feature of the ball valve is its compact structure and easy operation and maintenance. It is suitable for general working media such as water, solvent, acid and natural gas, as well as media with poor working conditions, such as oxygen, hydrogen peroxide, methane and ethylene. The ball valve body can be integral or combined.
Pneumatic butterfly valve is composed of pneumatic actuator and butterfly valve. Pneumatic butterfly valve is a pneumatic valve that uses the circular butterfly plate rotating with the valve stem as the opening and closing property to realize the opening and closing action. It is mainly used as a block valve. It can also be designed to have the function of regulation or section valve and regulation. Butterfly valve is more and more used in low-pressure large and medium-sized pipelines. Classification of pneumatic butterfly valve: stainless steel pneumatic butterfly valve, hard seal pneumatic butterfly valve, soft seal pneumatic butterfly valve and carbon steel pneumatic butterfly valve. The main advantages of pneumatic butterfly valve are simple structure, small volume, light weight and low cost. The characteristics of pneumatic butterfly valve are particularly remarkable. It is installed in a high-altitude concealed channel, controlled by two position five way solenoid valve, easy to operate and can also adjust the flow medium.
