News from this newspaper In March, Huang Ping Jianfeng Cement Company used maintenance to optimize the dust collection air on the top of the homogenized reservoir, and installed a negative pressure detection point at the gravity control valve on the top of the reservoir to timely monitor and control the dust collection air on the top of the reservoir.
Huang ping peak raw meal homogenization warehouse top dust collection fan was designed to install a damper actuator to facilitate timely adjustment. After production and operation, due to the lack of direct signal to instruct the central control personnel to timely adjust the best air use of the dust collection fan on the top of the warehouse, the operation of opening the inlet damper of the large fan to ensure the negative pressure condition in the homogenization warehouse occurs. At the same time, the negative pressure in the warehouse changes differently due to the large or small amount of material in the warehouse and the different operating conditions of the raw material roller.
manufacturing department in daily production from time to time to adjust the wind, found that the wind has a large savings space. After communicating with the electrical technicians, it was found that there were surplus signal channels in the system that could transmit signals to the central control DCS control interface. After technical discussions between the process and the electrical, relevant plans were formulated and implemented. After
is restored, the homogenization library shall be approved on site to ensure the optimal control value of micro negative pressure under different working conditions. Through the operation comparison at the end of 11 , the motor load can be reduced by current 4A when the raw material roller is started, and the motor load can be reduced by current 8A when the raw material roller is stopped, thus achieving the purpose of cost reduction.
