In the first half of 2015, the research data on the “urban and rural mining†development research carried out by the Guangdong Provincial Science and Technology Association showed that “the production of domestic garbage per capita in Guangzhou and Shenzhen in the Pearl River Delta region exceeded 1.3 kg/day, and the total annual production exceeded 600 respectively. Ten thousand tons and five million tons, and "Guangzhou's annual production of construction waste is more than 40 million tons." The daily garbage produced in Guangzhou exceeds 16,000 tons. It is transported by a single garbage truck with a rated load of 16 tons. It takes over 1000 times a day to ship the garbage. This can not be said to be a huge pressure on companies that undertake the tasks of garbage removal and transportation.
Taylor Malo Retarder Helps Garbage Truck Operation Safer
Not only in the Pearl River Delta, but also in other major domestic cities. The “2014 Annual Report on Solid Waste Environmental Pollution Prevention in Large and Medium Cities in China†published by the Ministry of Environmental Protection in December 2014 shows that the city’s municipal solid waste production in 2013 was the largest in Shanghai, with a total of 7.36 million tons. Followed by Beijing, domestic waste production in 2013 was 6.671 million tons.
Every day we need to clear and dispose of so much household waste. This is a daunting task for any refuse removal and transportation company. In order to accomplish this difficult transportation task, the "safety" and "high efficiency" of the transportation vehicles are two key words.
Garbage is produced in large numbers in densely populated cities. Garbage disposal sites are usually built in the suburbs. Removal and transportation of vehicles need to go between garbage transfer stations and waste disposal sites. The traffic conditions of this transportation route are complex – there are congestion roads in the urban areas and there are suburban expressways; there are densely populated areas, there are roads passing through schools and shops; there are Pingluo Road and ramps; along the way, there are a large number of traffic lights, and Pedestrians crossing the street at random have the same number of places. Ensuring that traffic is "safe" is a top priority for every garbage removal company.
With the ever-increasing task of waste removal and transportation, it is common practice to purchase more vehicles for removal. However, the increase in the number of vehicles brings about an increase in the difficulty of management, an increase in parking lots, an increase in the number of drivers and maintenance personnel, and an increase in operating expenses. Starting from improving transportation efficiency, it is often a more reasonable and more efficient solution, and it can also bring more economic benefits to the company. There are often three ways to improve transportation efficiency. First, the development of large-scale transportation vehicles; second is to improve the speed of transport vehicles; the third is to improve the attendance of transport vehicles.
However, "security" and "efficiency" are often contradictory. The greater the vehicle's weight, the faster the speed, usually means a reduction in traffic safety. The installation of Talemar eddy current retarder on domestic garbage trucks, Zhejiang Garbage Trucking and Transportation Co., Ltd. and Shanghai Environmental Co., Ltd. have made beneficial attempts and achieved good results. The efficiency of vehicle transportation improves the safety of vehicle operation.
The eddy current retarder is an auxiliary brake system added outside the main brake system of the vehicle. Its core role is to assist the vehicle in braking, thereby reducing the working pressure of the main brake and reducing the main brake caused by overheating. The brakes are weak, the brake parts wear faster, and even the brakes fail. The brake response speed of eddy current retarder is very fast, only 0.02 seconds. In case of emergency, the main brake and retarder can be used at the same time, which can shorten the braking distance by 20%-35% (different types of retarder, Different dynamic torque) to avoid traffic accidents.
The eddy current retarder is mainly composed of a stator and a rotor. The stator is fixed with the chassis of the vehicle. The rotor rotates with the drive shaft. When the work is required, the coil in the stator is energized to form an alternating strong magnetic field. The rotor cuts the magnetic lines of force to form eddy currents and forms the braking force opposite to the direction of rotation on the rotor. . From the point of view of conservation of energy, the eddy current retarder converts the kinetic energy of the traveling vehicle into electric energy of the retarder through eddy currents, and the heat is dissipated through air cooling of the rotor blades. There is about 1-1.5mm gap between stator and rotor of eddy current retarder. When working, stator and rotor do not contact, so eddy current retarder is a frictionless brake, commonly known as electric brake.
Shanghai Environmental Ltd. to install Tellabs Ma's track torque is 3000Nm eddy current retarder type of heavy truck ZZ3317N3267C removal vehicles, monitoring the same car in the same running route, using the retarder and unused slow Speed ​​of the hub surface. The monitoring results showed that the average temperature of the hub surface using the retarder was about 40% lower than when the retarder was not used. This shows that the use of eddy current retarder can greatly reduce the frequency of main brake work and extend the service life of brake pads and brake drums. Summer hot weather can reduce the chance of driving tires. According to feedback from driver Zhao, the braking effect of the eddy current retarder is very obvious. It is necessary to step down about 1/2 of the brake pedal travel before installing the retarder. After installing the retarder only Depressing the 1/3 or so pedal stroke will satisfy the braking requirement. At present, Master Zhao is very satisfied with the braking performance of the vehicle and is more confident in completing the goal of “No accidents throughout the year†formulated by the company this year.
The garbage removal truck of Zhejiang Garbage Removal and Transportation Co., Ltd. installed eddy current retarder to ensure effective control of the vehicle speed under various road conditions, effectively improved the braking performance of the vehicle, and improved the safety and smoothness of vehicle running. The service life of brake pads, brake drums, and tires has been extended; the cycle of replacement of brake system components has been greatly shortened; the increase in the service life of after-sales parts has ensured the attendance rate of clean-up vehicles, and has achieved better results The "safe" and "high-efficiency" goals of the car have brought considerable economic benefits.

It is believed that the installation of the eddy current retarder on the garbage truck will be more and more widely used!
Fine Bubble Diffuser is a necessary equipment for air blast aeration aeration.The selection of aeration equipment not only affects the effect of sewage biochemical treatment, but also affects the occupation, investment and operation cost of sewage farm.The main types of micro-hole aerators are: diaphragm type micro hole aerator, pipe aerator, disk aerator, micro-hole ceramic aerator, etc.
Diaphragm type micro orifice aerator is the most new type of aeration device. It has small aeration bubble diameter, small gas-liquid interface diameter, large gas-liquid boundary area, and uniform bubble diffusion, which will not cause hole blockage and strong corrosion resistance.
