Dongfeng Dolika sprinkler 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.

Component description
One, special car chassis Currently widely used are "Dongfeng Furica sprinkler (flat head), Dongfeng Dima sprinkler (flat head), Dongfeng Doolika sprinkler (flat head), Dongfeng Sanpingcha sprinkler (flat head), Dongfeng 140 sprinkler ( Long head), Dongfeng Tianjin sprinkler [1] (flat head), Dongfeng 145 sprinkler (flat head), Dongfeng 153 sprinkler (flat head), Dongfeng small three-axis sprinkler (flat head), Dongfeng Houqiao Shuangqiao Sprinkler (Flat), Dongfeng Tianlong Shuangqiao Sprinkler (Luxury High Top).
Second, the tank production Automatic production line tank production process is divided into: cutting, automatic welding puzzle, head spin forming, tank rolling and other domestic advanced production technology. Tank materials are mostly made of high-quality carbon steel plates. In case of special use, it can also use imported Korean 304 stainless steel according to customer's needs. The volume of the tank is "3 cubic, 4 cubic, 5 cubic, 6 cubic, 8 cubic, 10 cubic, 12 cubic, 15 cubic, 20 cubic, 25 cubic, and 30 cubic."
Third, the pipeline system By pipelines, valves, filtration devices, outlets (pre-spray, sprinkle, side spray; high-side shower; rear working platform, with green high-pressure sprinkler).
Fourth, the operating system The transmission is driven mainly by the engine. The power take-off mounted on the transmission drives the sprinkling pump. The sprinkling pump generates power and sprays the liquid inside the tank through the pipe network. Scope of work: Self-priming height: ≤7m, Sprinkling width: ≥14m, Maximum range: ≥28m; Adjustable into straight punch, heavy rain, light rain, drizzle, range ≥30m; also adjustable to fog, with a range of ≥15m.
Five, sprinkler Equipped with the first national quality appraisal Cheng Liwei (Japanese technology) high-power special sprinkler pumps, with fire joints, with self-flow valve, with self-priming function, optional 20 meters green fire reel.
Dongfeng optional configuration Can be equipped with sprinkling discs, drug pumps, anti-corrosion rust tank, multi-directional inlet and outlet connections, solenoid valves, pneumatic valves and other advanced facilities to meet the needs of different users
Dongfeng sprinkler tank
Tank door assembly The large cover is fastened to the tank door neck plate by a bolt and is connected by a support pin and a cover plate cover. The clockwise rotation of the handle above the small cover allows the small cover to be pressed tightly. In the process of adding water, the pressure in the tank is basically the same as the atmospheric pressure.
Tank plate thickness The Dongfeng Sprinkler with a capacity of 8 cubic meters or less is generally repressed with a national standard 4.0mm carbon steel plate. The Dongfeng Sprinkler with a capacity of 8 cubic meters or more generally adopts the national standard 5.0mm carbon steel plate to press, and is welded to a straight body. The tank mouth is closed by a pressure valve. There is a communicating device at the opening of the head (the internal water level can be observed).
Tank shape Divided into oval tank, circular tank, square circular tank.
Water Sprayer Function Description
The sprinkler is equipped with a duck-shaped nozzle or a round-headed punching nozzle, a cylindrical open-spray nozzle or a showerhead nozzle at the back, and a working platform at the rear, equipped with a water cannon. 8 nozzles at the rear (optional)
Sprinkler use scope: It is mainly used for road flushing in large, medium and small cities, trees, green belts, lawn greening, construction of roads, factories and mines, and high-rise building flushing. With sprinkler, dust, high and low spray, pesticide spraying, fence washing and other functions, but also has to carry water, drainage, emergency fire and other functions.
