Cinder machine old brand, Xinhua machinery (certified), Cinder machine 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. The main reasons are: ① hydraulic oil filter, inlet pipe blockage or oil viscosity is too high, can cause the inlet of the vacuum pump is too high slag dryer, air infiltration. ② pump, the pilot shaft end seal damage Cinder machine brand, or inlet pipe seal is bad, causing air to enter. Oil tank is too low, so that the pump suction air directly into the pipeline. When working in a high-noise pump occurs, you should first check the above site, identify problems in time. (2) excessive wear on the pump internal components, such as piston cylinder and valve plate, piston and piston bore mating parts such as wear and tear, injury, make a serious leak in the pump, when the pump output pressure, small The flow pulsation generated when the oil flow, causing a higher noise. At this angle may be appropriate to increase the pilot system variables institutions to improve internal leakage impact on pump output flow. Hydraulic servo valve spool, to control the flow of the piston also because of partial wear, strain, pulsation in the piston movement, cause fluctuations in the hydraulic pump output flow and pressure, resulting in a large vibration and noise at the pump outlet . Response options: then you can wear, serious injury spotting brush element or replacement processing. Cited Han Wei River diversion plan from the Han River upstream to the Weihe River in Southern Shaanxi Guanzhong area, the main task of the project is important to the Weihe River in coastal cities, counties, industrial parks water, and gradually returned to agriculture and ecological water diverted Cinder machine uses to promote regional economic and social sustainable development and improve the ecological environment. Project to take "a project in phases with water" building program, the progressive realization of 2020 with 500 million cubic meters of water, 2025 with 1 billion cubic meters of water, in 2030 with 1.5 billion cubic meters of water.
