How big is the impact of vehicle emissions on smog? In the seminar held by the National Motor Vehicle Pollution Prevention and Control Professional Committee and other units jointly organized by the National Motor Vehicle Pollution Prevention and Control Committee and other units, the researcher of the Motor Vehicle Emission Control Center of the Ministry of Environmental Protection, Han Yingjian, on the issue of motor vehicle pollution Learn to read.
Han Yingjian said that the proposal of the Democratic National Construction Association this year on the Beijing-Tianjin-Hebei joint defense and crackdown on air pollution problems said that at present, the total number of motor vehicles in Beijing, Tianjin and Hebei has exceeded 25 million, and the emission standards for large transport vehicles have been updated slowly. The current situation of low oil standards and large pollution discharges has brought great pressure on the prevention and control of atmospheric pollution. In recent years, smog in China has continued to occur, which is closely related to vehicle exhaust emissions.
But what is even more worrying is that "there are a lot of environmental frauds in the new car and in-use vehicles." According to Han Yingjian's investigation, there are many car manufacturers who are stealing columns and selling "Fake Country III" cars. Many places are taking the country I to deal with the country III, which is the unspoken rule of the automotive industry. Moreover, "these car companies are not at the corners, and their names are known to all the people in the country."
Relevant investigations found that in order to reduce the upgrade cost, some manufacturers played the game of "cat and mouse" with the regulatory authorities, cut corners on the three-way catalytic converter, and changed the "three yuan" to "two yuan", resulting in no treatment of nitrogen oxides. Direct discharge into the air.
"Fake country III diesel vehicles began production and sales in January 2008, and last year, long-term raging and flooding caused huge high emissions." Han Yingjian said that if the situation of illegal production of non-standard vehicles is not reversed as soon as possible, Seriously hinder the improvement of atmospheric environmental quality, and the emission reduction effect brought by the upgrade of automobile standards will also face the risk of being offset.

Slurry Pump includes horizontal slurry pump, vertical slurry pump, submersible slurry pump, etc. For horizontal slurry pump, there are metal slurry pump and rubber lined slurry pump.


Horizontal Metal slurry pumps are cantilevered slurry pumps, Horizontal Centrifugal Slurry Pump, Centrifugal Pump Theory Slurry Pump,  Heavy Duty Centrifugal Slurry Pump. They are designed for the handling highly abrasive, high density slurries in the metallurgical, mining, coal, power, building material and other industrial departments etc. The pumps of this type also may be installed in multistage series.
The frame plates have replaceable wear-resistant metal liners. The impellers are made of wear-resistant high chrome alloy .
Horizontal Metal slurry pumps may be adoptable of gland seal or expeller seal. The discharge branch can be positioned at intervals of 45 degrees by request and oriented to any eight positions to suit installations and applications.

Rubber Lined Slurry Pumps and spare parts can fully interchange with world famous brand. These pumps are of heavy-duty construction, designed for continuous pumping of highly abrasive and corrosive slurries. They feature a wide choice of replaceable abrasion resistant metal or moulded elastomer casting liners and impellers, which are all interchangeable within a common costing assembly.

BV pumps are vertical, centrifugal slurry pumps submerged in sump to work. They are designed for delivering abrasive,large particle and high density slurries. These pumps have no need of any shaft seal and sealing water. They can also be operated normally for insufficient suction duties. Wet parts of type BV pump are made of abrasion-resistant metal. All parts of type BVR pump immersed in liquid are lined with rubber outer liner. They are suited to transport non-edge angle abrasive slurry.

ZQ(R) series of slurry pumps are hydraulic devices composed of coaxial motors and pumps that are submerged in the fluid to work. These pumps are characterized by unique structure wide passage, high capacity of removing sewage, and high quality materials, offering excellent corrosion resistance. They are suitable for transferring the liquid containing solid particles, like sand, coal slag, and tailings, and removing slurries in metallurgical plants,mines, steel mills, or power plants, as an ideal alternative to traditional pumps for taking away slurries
