Tunnel project quotation, Xinhua machinery (certified), the tunnel project is provided by Gongyi City Xinhua Machinery Factory. Gongyi City Xinhua Machinery Factory (www.gyxinhua.com) is specialized in the "Cinder machines, construction machinery, mining machinery, chemical machinery" of the enterprise, the company of "honesty, hard service" concept, to provide you with the most quality products and services. Welcome to inquire! Contact: Mr. Wang. We must first determine the location of the sound source tunneling slag, they are likely to occur in these areas: 1, the noise from the hydraulic cylinder (1) hydraulic oil mixed with air or hydraulic cylinders in the air is not completely drained in under high pressure cavitation caused big noise. Response options: At this point, the air must be promptly drained. (2) slag machine cylinder head or piston rod seal tight bend loading tunnel project in the course of the campaign but also because of other fresh produce noise. Response options: At this point, need to be replaced or straightening rod seals. 2, the noise from the piston pump or motor (1) cavitation phenomenon is one of the main causes excessive pump noise. When the oil is mixed with air, easily formed in the high-pressure zone cavitation tunnel project, and in the form of pressure wave propagation, causing fluid oscillation, causing the system to generate cavitation noise. Chinese Academy of Engineering Lipei Cheng: "We can supply diversion from the Han Wei part of the Yellow River (water) from the Weihe River, and then transferred inside some water from the Yellow River (upstream) to give northern Shaanxi, and therefore it is not only a diversion from the Han Wei relief off the water, And it can contribute to the construction of energy bases in northern Shaanxi valuable. 巩义鑫 China Machinery Factory is a professional production of slag machine manufacturers willing to sacrifice the power of livelihood projects to this end!
