① "to repair the generation of support" the idea exists. Absolutely no technical maintenance program, the machine often take "sick" operations only when the machine can no longer work, only for repair. ② due to harsh environmental conditions, site constraints, technical maintenance and maintenance requirements do not press the "quantity" conduct, but think of what care what, what to see what maintenance. ③ low quality of personnel to participate in maintenance can not be brick, nor by the appropriate maintenance records and maintenance procedures. ④ when the capital was more scarce, not timely maintenance, or use of fuel and spare parts irregularities. ⑤ when tight deadlines to finish the work, do not make good Which brick factory scheduled maintenance, neglect of health and forced mechanical operations. How do I know the reasons for slower speeds brick equipment Which best brick machinery, it must know the speed of block brick hydraulic system component which is mainly controlled by it? Put a new term electromagnetic proportional throttle introduce to you. Yesterday, speaking on proportional relief valve and electromagnetic relief valve function, where the difference is not much good brick machine manufacturers are open relief overflow when the system pressure exceeds the set value; the difference is that the proportion of the overflow valves can be adjusted in proportion to set overflow traffic, more precise control of the system. General relief is both open and closed positions, the proportion of the overflow valve in the open position can have more than one. Which is the best brick machinery, double-Sheng Machinery (certified), brick by Zhengzhou double Sheng Machinery Manufacturing Company Limited. Zhengzhou double Sheng Machinery Manufacturing Co., Ltd. (shuangshenggongsi.com) is Zhengzhou, machining leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the double-Shing Machinery leadership with the staff warmly welcome all inquiries negotiations to create double-Sheng Machinery better future.
