Swimming Pool Solenoid Dosing Pump
swimming pool solenoid pump,swimming pool dosing pump
*Swimming pool water treatment: dosing chlorine dioxide
*Industries: e.g. paper industries, plastic industries, tissue industries: dosing additives
*Potable water treatment: dosing disinfectants
*Several types: manual control or automatic control, the automatic control can divided to: 4-20mA electric current signal control, digital impulse signal feedback control, digital impulse feedback control with Rs485 communication interface, 4-20mA electric current signal control with Rs485 communication interface.
*High speed operation: high measurement precisions, up to 360 strokes
per minute which eliminate the pulsation
effect.
*Compact size: small, quiet and stable
operation
*Durable diaphragm: the diaphragm is made by PTFE, which is
compatible with all kinds of chemicals. In typical use, the diaphragm
can last up to five years, which 5 times as national standard
GB/T7782-2008
*Strong stability: working stability in AC 100-240V, and
suitable for the range of
50-60Hz
* High protection level: protection level reached to IP65,
it allowed pump to provide safe services at severe operaton
condition
*Ball check valves: it through double valve ball, seat and
sleeve to form the sealing system, that enhance the
precision
*Percentage adjustment: local adjust percentage for stroke
and frequency
0~100%
*Level monitor, low-level shutoff with alarm output

Are the explosion-proof lights used in gas stations now using LEDs? The introduction of LED explosion-proof lights is the leading market in the future. Although LED light source lamps have higher prices, they have the following advantages over traditional metal halide lamps:
First, security is better: 1, LED light source relative to metal halide light source, the heat is smaller than the metal halide lamp, safety is better, not easy to produce a lot of heat and increase the indoor temperature. 2. The output of LED lamps is DC 35V, which is a safe voltage. The current is also small, so it is not easy to produce sparks. It is safer than metal halide lamps.
Second, more energy-efficient, 50wLED explosion-proof lamp prices are higher than the price of metal halide lamps, but from the long-term energy-saving calculations, savings in electricity costs in general can be about three years or so to make up for the difference in lamps;
Third, the longer life: ordinary metal halide lamp life of about 10,000 hours or so, 10000-15000 hours, light, electrical appliances have to be replaced, the cost of light sources and electrical appliances accounted for about 60% of lights. LED lamps, light-emitting chip life of 50,000 hours or so, electrical life of 25,000 hours or so, maintenance is generally just to replace electrical appliances, only a few tens of dollars on it. Because of the longer life, fewer repairs and maintenance costs.
LED explosion-proof lighting notes:
First, the technology has gradually matured, but the quality of products on the market is uneven, good products can play the excellent performance of the above products, so buy products must choose the regular company products. It is best to choose a company with LED chip packaging technology.
Second, LED explosion-proof lights used in the oil depot, can only fight for the original use of the following 250W metal halide lamps, for lighting is too high, or Gaoming area is too large, it is recommended to use metal halide lamps, like the current petrol station is generally 4.5 meters to 10 Between the meters high, with the LED explosion-proof lamp 100w almost brightness can be achieved, do not worry.
Third, the use of LED explosion-proof lamps at gas stations and oil depots requires explosion-proof or intrinsically safe lamps. The explosion-proof level must be T4-T6.
What advantages do ED explosion lamps have over metal halide lamps? What should you watch out for when purchasing?
