Shanghai Daoqin Plastics Co., Ltd.

        一, 振动泵噪音 generate causes and troubleshooting methods

         causes:

        1, electrical machine different 心.

        2, device 松动.

        3, internal fault/failure.

        4, low, from 滤油网 or 接头连接处吸入空 gas to liquid inner.

        5, from electrical machine make 动轴处吸入空 gas.

        6, 油污堵塞滤油网.

        7, tube/pipe 松动吸入空 gas or tube/pipe in upper, mixed gas to liquid in.

         fault/failure troubleshooting methods:

        1, degree 应调至0.1mm以 inner.

        2, positive device.

        3, or more 换油泵.

        4, increase amount in 滤油纲 and 接头位置400mm above.

        5, more 换转动轴密封圈.

        6, 清洗滤油网, liquid.

        7, 清洗滤油网, liquid.

        8, 锁紧回油 tube/pipe 路, will tube/pipe add long to 油面之 lower.

        二, electrical machine generate causes and troubleshooting methods

         causes:

        1, electrical machine bearings loss bad.

        2, electrical machine 线圈绕组 fault/failure.

        3, electrical machine 接线错误, system pressure upper rise 时, increase large.

         fault/failure troubleshooting methods:

        1, more bearings.

        2, more or electrical machine.

        3, heavy new 参照接线图接线.

        三, pressure 阀噪音(溢流阀) generate causes and troubleshooting methods

         causes:

        1, 溢流阀 先导阀 front inner has gas.

        2, 溢流阀主阀心 upper retardant by material 堵塞.

        3, 先导阀 and base/seat combined 拉伤不密 combined.

        4, elastic deformation or 装错.

        5, 遥控口油流 amount large.

        6, liquid pressure viscosity low or high.

        7, and in parts generate 共振.

         fault/failure troubleshooting methods:

        1, add strong/high 密封, rise drop debugging pressure 几次排 gas.

        2, 清洗阀体, make retardant 尼孔通畅.

        3, or more 换.

        4, and more elastic 簧.

        5, decrease/reduce 遥控口流理.

        6, more liquid.

        7, its it parts pressure setting can and 溢流阀 pressure setting value versus 近.
