Problems solved by technology
[0003] When the excavator is working, the position of the working device on the vehicle is constantly adjusted, which requires the continuous start and stop of the slewing drive device. The work of the slewing drive device has the following characteristics: the flow required for acceleration is small and the pressure is high, and the required flow rate after acceleration is completed. The flow rate is large and the pressure is low, and the rotary oil supply is usually provided according to the flow rate after acceleration. During acceleration, the excess hydraulic oil will overflow from the safety valve of the rotary drive device. Similarly, when the rotation stops, in order to generate braking force, the rotary motor discharges The pressure oil often flows back to the oil tank in the form of multi-way valve spool throttling or safety valve overflow, so that most of the hydraulic energy provided by the circuit is converted into heat energy and is wasted in vain. To prevent the damage to the system caused by a large increase in the temperature of the hydraulic oil, a cooling device is also required

The invention discloses a boarding rotating energy recycling system. The boarding rotating energy recycling system comprises a multi-way valve, a boarding rotating device, a working pump, an energy collecting device, a control block and a corresponding connector. By using the system, overflow energy during startup and brake of boarding rotation can be effectively recycled, overflow can be prevented when the working pump is used for supplying oil to other working devices, and the collected energy can also be released for doing work according to needs, so that the purposes of reducing heat productivity of the system, reducing the energy consumption of a prime motor, saving energy and improving working efficiency can be achieved.
Description
technical field [0001] The invention relates to an energy recovery and utilization system, in particular to an energy recovery and utilization system for boarding and turning. Background technique [0002] Construction machinery and agricultural equipment often use fluid transmission to operate various mechanical components. For example, an excavator is a commonly used construction machine, and pressure oil is often used to act on the slewing motor to realize the slewing of the excavator on the vehicle. [0003] When the excavator is working, the position of the working device on the vehicle is constantly adjusted, which requires the continuous start and stop of the slewing drive device. The work of the slewing drive device has the following characteristics: the flow required for acceleration is small and the pressure is high, and the required flow rate after acceleration is completed. The flow rate is large and the pressure is low, and the rotary oil supply is usually prov...
