Problems solved by technology
In the hydraulic system of the crane, the hydraulic pump is the power source of the hydraulic system of the crane. Improper control will make the work of the crane fail to meet the requirements. In severe cases, the crane may be damaged and cause engineering accidents. Therefore, the hydraulic pump must be reasonably adjusted Regulation and real-time monitoring
At present, the hydraulic pump monitoring system of the crane has complex structure, high cost, low energy efficiency utilization rate, and slow response to faults

The invention provides a monitoring system of a crane hydraulic pump. The monitoring system comprises a PLC, a hydraulic pump control electronic element, a human-computer interface control unit, a proportional valve, an axial plunger hydraulic pump, a valve position sensor, a pump rotating angle sensor and pressure sensors. The hydraulic pump control electronic element is connected with the PLC through a communication cable. The PLC is connected with the human-computer interface control unit. The proportional valve, the valve position sensor, the pump rotating angle sensor and the pressure sensors are connected with the hydraulic pump control electronic element and the hydraulic pump. The monitoring system has the beneficial effects that the monitoring system can independently control each hydraulic pump, the precision of control over displacement is high, and the structure of the system is simple; and compared with a traditional valve control system, energy efficiency is improved by 50% or above, and the pressure of the hydraulic pump, the valve position and the rotating angle of the hydraulic pump can be accurately monitored in real time.
Description
technical field [0001] The invention relates to the field of crane monitoring systems, in particular to a monitoring system for crane hydraulic pumps. Background technique [0002] At present, in the field of marine engineering, knuckle-boom cranes installed on ships are indispensable special equipment for offshore construction and logistics supply. In the hydraulic system of the crane, the hydraulic pump is the power source of the hydraulic system of the crane. Improper control will make the work of the crane fail to meet the requirements. In severe cases, the crane may be damaged and cause engineering accidents. Therefore, the hydraulic pump must be reasonably adjusted regulation and real-time monitoring. At present, the hydraulic pump monitoring system of the crane has complex structure, high cost, low energy efficiency utilization rate, and slow response to faults. Contents of the invention [0003] In order to overcome the above-mentioned problems, the object of the...
