The led rgb flood light is made of aluminum alloy die-casting and electrostatic spraying surface treatment. The coating is resistant to high temperature, acid and alkali, and anti-aging. The lamp body adopts the integrated design of light source and electrical appliances, with compact structure and small volume.
The reflective surface is designed to form various required light distribution, with high luminous efficiency and low light source glare. The lamp head is made of tempered glass, which is safe, high temperature resistance, high strength and good light transmission. The sealing strip is an anti-corrosion silicone rubber sealing strip, which has good sealing performance and is suitable for waterproof and dustproof applications.
You can control the color change of the led floodlight rgb through a mobile phone to achieve all color spectrums and be used in various places. Due to its convenience and full spectrum lighting, rgb Led Flood Light can be used as outdoor LED flood light for Christmas, Halloween lights festivals.

Mobile diesel pump structural features and uses
[Asia Pump Network News] KDH-type diesel engine pump - flood control drainage diesel engine drainage pump, the choice of horizontal, single-stage pump, single suction, volute mixed flow pump. The use of centrifugal force generated by the impeller rotation and thrust joint work, oblique outflow, also known as ramp pump, a scroll (horizontal) and guide vane (vertical) two. Now take a look at the characteristics of mobile diesel pump structure and use. Diesel pump First, the mobile diesel pump Features 1, both centrifugal pump and axial pump advantages, simple structure, reliable, easy to install, and high efficiency, the problem is small, light weight. 2, transmission mode: a direct drive and variable speed drive, commonly used power machine is a motor and diesel engine. Ordering should be clear power machine model (power, speed), in order to determine the coupling or pulley specifications. 3, the pump direction: To the pump inlet, the impeller is generally counterclockwise rotation (650KDH-5, -7, -10 pump clockwise rotation). Second, the mobile diesel pump structure 1, KDH pump mainly by the pump cover, impeller, pump, pump shaft, bearing and bearing body (diameter ≤ 350mm) or bearing frame (diameter ≥ 400mm) and other major components. 2, pump cover, respectively, in the pump body and inlet connected. Pump cover plane and the plane between the impeller should have appropriate clearance. The gap is too small will produce friction; clearance is too large, will lead to a large number of pressure pump backflow of water to reduce the efficiency of the pump. The actual use of the appropriate gap of 0.3-0.7mm (the pump shaft to the pump inlet), the gap can be increased or decreased pad thickness to adjust. 3, Shaft sealing device consists of packing, packing gland, packing ring, and stuffing box on pump body (100KDH, 150KDH and 200KDH type pump without packing ring). Its role is to prevent air from being drawn into the pump and to prevent excessive flow of water out of the pump along the shaft. 4, sleeve to protect the shaft, wear and timely replacement. 5, the pump shaft with single row radial ball bearings support. Bearings can be lubricated with oil - oil should be controlled in the oil benchmark between the lines; also can be greased - can be added when the pump assembly, in use by removable front and back cover to supplement. 6, the top of the pump body screw holes for filling irrigation or pumping vacuum suction pump diversion. 7, in order to expand the use of the pump to meet the different requirements of users, you can cut the impeller diameter or use different properties of the impeller (plus A). 8,100-350KDH-type pumps have inlet and outlet dumbbells, bent, bottom valve and pulley or coupling; 400-650KDH pump inlet and outlet with a setback, check valve and pulley or coupling . Available for user selection. Third, the scope of mobile diesel pump knot 1, for plain polder farmland irrigation and drainage pump stations, industrial and urban water supply and drainage and other occasions. 2, used to transport water or other physical and chemical properties similar to water. 3, be transported liquid temperature should not be higher than 50 ℃. 4, volute-type lift 5 ~ 12m, flow 900 ~ 4000m3 / h; guide vane lift 3 ~ 25.7m, flow 45 ~ 20160m3 / h.
