According to the latest data released by Infiniti, in October 2015, the brand's retail sales in the Chinese market was 3,740 units, an increase of 29.2% from the 2,895 units in October last year. In the month, domestic models accounted for 63.3% of Infiniti's sales in China. The Infiniti Q50L is the highest-selling model, reaching 1,413 units. The "50 family" consisting of Q50, Q50L and QX50 sold 2,640 units, accounting for more than 70% of total sales. In October, Infiniti sold 18,400 vehicles worldwide, up 20% year-on-year, the highest sales record in the same period of history, and maintained its highest monthly sales record for 14 consecutive months. From January to October, Infiniti sold a total of 32,169 vehicles in China, an increase of 35.8% year-on-year, surpassing last year's full-year sales two months ahead of schedule. Pneumatic Pump is a new type of transport machinery, is the most novel type of pump in China.Using compressed air as the power source, all kinds of corrosive liquids, granular liquids, high viscosity, volatile, inflammable, highly toxic liquids can be exhausted by light absorption.Invented by American engineer William wilton, the pneumatic pump was introduced to China.There are five kinds of materials commonly used: plastic, aluminum alloy, cast iron, stainless steel and teflon.According to different liquid media, Diaphragm Pump adopts buqing rubber, chloroprene rubber, fluoro rubber, polytetrafluoroethylene, polytetrafluoroethylene respectively.The early domestic customers bought through the importer agent, the price is expensive and the maintenance is complicated.With the development of industry, the market share of domestic Pneumatic Diaphragm Pump has exceeded that of imported products.In order to install in a variety of special occasions, used to pump a conventional pump can not pump the medium, all achieved satisfactory results.

neumatic diaphragm pump is a new type of conveying machinery, using compressed air as power source, for all kinds of corrosive liquid, with particles of liquid, high viscosity, volatile, flammable, poisonous liquid, it can be smoked light, has formed a production, product quality, are welcome.The main characteristic of this kind of pump is without irrigation water diversion, both can flow pumping liquid, and can transport fluid medium, some grain flow can control freely according to the size of air pressure, adjustable head (0 to 50 meters), air pressure or work only more than 1 kg/cm2, absolutely for fire and explosion prevention, submersible pump, self-priming pump, all impurity pump, shield pump, slurry pump function, and many features of the conveying machinery.
Diaphragm pump flow, characteristic selection
Diaphragm pump flow characteristic is refers to the medium flow through the valve of the relative flow and displacement (relative opening degree of valves), the connection between the ideal flow characteristic mainly has straight lines, such as percentage (log), parabolic and quick opening, four kinds of characteristic curve and the shape of the valve core as shown in figure 1 and figure 2.The usual ideal flow characteristics are straight line, equal percentage (logarithm) and fast opening.Parabolic flow characteristic between straight line and equal percentage, the percentage of properties such as generally available to replace, and quick opening feature is mainly used for two control and program control, so the choice of diaphragm pump characteristic is, in fact, the choice of straight lines and equal percentage flow characteristics.
