Recently, the US Department of Energy (DOE) issued a federal bulletin on the test procedure for integrated LED lamps. Integral LED lamps required to enter the United States must be tested in a qualified laboratory in accordance with the requirements of this test procedure to obtain total luminous flux, input power, efficacy, correlated color temperature, color rendering index, power factor, lifetime and standby. Data such as power. The regulation came into effect on August 1, 2016 and was enforced on December 28, 2016. According to the requirements of this regulation, the above parameters must be tested in accordance with the standards of LM-79, LM-84, TM-28 and IEC6 2301. In addition, from August 1, 2016, DOE-controlled LED Lighting Facts (color label) will be suspended for all new replacement Lamps submissions, as the new integrated LEDLamps DOE test program: DEPARTMENT OF ENERGY 10 CFR Parts 429 and 430 came into effect on August 1, 2016. Moreover, DOE is about to officially release the non-integrated LEDLamps test program for non-integrated LEDLamps. Any application for listing submitted before August 1, 2016 will continue to be processed. Products that have already been listed for the DOE LED Lighting Facts are still kept in the database database. The LED Lighting Facts Working Group will conduct further investigations and research on the latest DOE regulations and will notify all partners as soon as a final decision is made. DOE LED Lighting Facts will continue to accept the delivery of LED luminaires and refurbished kits. DLC has also revised its requirements for LED Lighting Facts. From August 1, 2016, it will no longer be required to submit LM-79 data for bare lamps to LED Lighting Facts. Please note that DLC will continue to accept certification applications for lamps. This change does not affect DLC's requirements for LEDLightingFacts for other categories of products. About DOE LED Lighting Facts: DOE LED Lighting Facts is a voluntary performance labeling program for the US Department of Energy DOE for LEDSSL solid state general lighting products including: integrated LED bulbs, non-integrated LED bulbs, LED fixtures, and LED retrofit kits. Through this project, LED manufacturers can submit samples in authorized laboratories based on industry standards such as IESNALM-79-08, and then submit reports to obtain DOE LED Lighting Facts, thus showing their excellent product performance. North American latest standard express UL 1993 standard update At present, with the continuous introduction of new LED lamp (TypeA/B/C), LED filament lamp, LED module driverless, etc., UL is updated according to new products and new technologies. Relevant technical requirements of the standard. The latest UL certification requirements for LED light source products and the update of the UL 1993 standard are as follows:
Welded Cement Silos (Single Piece)
The cement silo (cement tank) has a cylindrical structure, and the bottom is supported by four round tube legs. The whole silo is in the form of steel structure and welded; the top is provided with a dust collector and a pressure safety valve.
Cement silo (cement tank) has the following parts: the silo body steel structure part, the ladder, guardrail, feeding tube, dust collector, pressure relief valve, high and low level meter, the discharge valve, etc
The horizontal feeder has large capacity, high volume utilization, convenient installation and adjustment, compact structure, light weight, easy operation and convenient transfer; small terrain restriction, easy for process layout.The main machine is mainly composed of double cone tank feeder, unloading port gas system and tank support.
