In 2009, Dongfang Ships purchased 14 pneumatic diaphragm pumps from Jianglang Company originally intended for the design of chemical tanker cleaning tanks of 8.4 meters in height. The maximum suction lift of pneumatic diaphragm pumps is only 7 meters, but the company's Pneumatic diaphragm pump through technical improvements: the use of highly reliable air motor design system and its gas distribution system, suction stroke can reach the requirements of major shipyards. March 2010 East officially put the pump into operation, mounted on the deck of the seven diaphragm pump suction height of 22 meters, the net difference of 15 meters, which is 2.8 times the original design institute height of 2.8 times, 8.4 meters suction stroke in the history of pneumatic diaphragm pump is already rare, and let him draw up to reach 22 meters that is simply Tianfang night talk, even more incredible. Design institutes and the reality of the existence of the difference between the hull manufacturing is the design of the problems and Jiang Lang company's product itself has nothing to do. Can be seen away from the ship to the owner only a few days time, this time the customer Dongfang Shipyard has become ants on the wok, square chaos. In response to this situation Jiang Lang immediately organized seminar group, focusing on the actual, finally breaking the storm. Through the technical transformation of the suction pipe and special treatment, with Jiang Lang company special three-way valve and its pressure regulating valve, increase the amount of compressed air along the way, so as to achieve the perfect combination of regulating valve, pipe and diaphragm pump, so that the liquid Smoothly be promoted. Successfully solved the problem of pneumatic diaphragm pumps up to 22 meters, which is also evidence that he said: "The miracle of the emergence of necessity rather than accidental!" At present, the company in the field of pneumatic diaphragm pumps have been Patent certificate of more than 20, of which pneumatic diaphragm pump automatic level control and pneumatic diaphragm pump set of quantitative control equipment has been awarded the honorary title of high-tech products in Shanghai, and the successful well-known large companies at home and abroad to solve the fluid transport Major problems: Waigaoqiao Shipyard in Shanghai, Jiangnan Shipbuilding Changxing base, Oriental Shipbuilding, Qingdao Shipbuilding, Germany Bayer, Yangzi Petrochemical, BASF chemical companies have been supporting the use of.
