"Measurement" is to install pressure gauge on the valve mouth of accumulator to judge when the hydraulic station is under standoff state. If the pressure gauge shows low pressure or no pressure, it means that the accumulator is damaged; If the pressure is close to the normal pressure of the ling, the accumulator is in good condition.
"Look" is to observe whether the lifting or pressure time of the roller is normal on site. If the roller is lifted or the pressure time is obviously prolonged, it indicates that the ling of the accumulator is damaged.
The most fundamental measure to solve the problem of ling damage is to stabilize the operation condition of ultrafine vertical mill and avoid the severe vibration of ultrafine vertical mill. In addition, a reasonable nitrogen filling method is also a factor to avoid the burst of lings.
