First, the foreword
Drilling type of sand mining is the ceiling of sand pump as the main components of sand, the ceiling of sand pump suction in the water of river sand or mud suction and after the sand tube row to the specified location. Once again to two times of cleaning cleaning eventually become qualified after transfer to the sand belt on the barge. This machine is applicable to large rivers, coastal ports and sand dredging engineering. Much for the use of mobile operations. Inland river sand mining, sand mining capacity of dozens of tons, thousands of tonnes. Large river dredge mechanization and high degree of automation, a ship can become a production unit and can carry out sand and gravel separation selection of cleaning process.

Two, the shortcomings of the original equipment
Through the analysis and summary of the field equipment working condition and the original control mode, the following disadvantages:
1: bucket wheel speed need artificial constantly according to the amount of sand to adjust, and basin sediment is uncertain, this increases the labor intensity of the workers in the field, frequent manual operation will bring the system instability of mechanical structure. Sometimes because of basin sediment amount of judgment is not accurate, or artificial negligence adjustments are not timely, resulting in bucket wheel sand content too many cards death motor transport.
2: equipment start-up circuit is complex, not only prone to failure, and the effect is not good, the entire hull power supply and power generation equipment.
3: the original control method does not have the speed adaptive, closed-loop control of the ability, manual adjustment will inevitably result in a waste of power, increase the load of marine generator.
Three, Yi chuangfei solutions
The main control part adopts VE200 series PLC and analog input and output module (module acquisition precision 14, the resolution is higher than the industry similar products), the completion of the field signal acquisition analysis. Due to the strong computing power of VE200 series PLC, the user can set a variety of running curves on the touch screen according to their own needs.
VI10 series touch screen to achieve on-site control mode switch, equipment running at all times observation and monitoring. Drive part of the company's star product ECF100 series inverter. The whole system effectively solves the problems of soft start, wheel bucket speed regulation, electric protection and so on.
Four, Yi chuangfei system solution advantage
1, smooth operation, system according to the amount of sand automatic adjustment bucket wheel of sand excavation speed closed-loop control to achieve will greatly reduce the artificial errors lead to failure.
2, to reduce the operator, each ship has a total of eight rounds of fighting, in the past two operators need to guard, after the transformation is no longer needed personnel operations, direct savings of two human.
3, energy saving effect is obvious, and real-time adjustment to smooth, reduce sand bucket wheel dissatisfaction or idle state.
4, the system adaptability is strong, can be applied to different power equipment, only need to adjust the torque can be used.
5, the whole system controller with Yi Chong Fei company independent research and development of products, strong hardware and software vertical integration capabilities for the stable operation of the system, the rapid technical support and after-sales response provides the possibility.
