Description
Technical Field
The invention relates to the field of hydraulic pressure and digital hydraulic pressure, in particular to a digital valve with functions of energy recovery, flow monitoring, fault detection and remote communication
Background
The hydraulic technology is the most core technology for supporting heavy and super-large loads, and is widely applied to relevant equipment such as aerospace, ships, heavy machinery and the like. The traditional hydraulic industry is difficult to have deeper breakthrough in the face of the problems of leakage, high energy consumption, inconvenient maintenance and the like. With the development of the internet in China and the proposal of 'manufacturing in China 2025', the existing semiconductor and internet technologies are integrated, the hydraulic technology is pushed to the high-end technology industry to break the industry barrier, and the hydraulic industry upgrading is of great significance.
In the digitization process of the hydraulic industry, the digital valve is dependent on the power electronic technology to adjust indexes such as flow, direction and pressure in the application process, but in the practical application process, power supply is seriously dependent on an external power supply system, most of the application environments are in outdoor environments, the environments of power supply and transmission links are severe, short circuit, electric wire damage and the like are easily generated to cause power failure, so that the power supply is unstable, and the function of the digital valve in the hydraulic system is seriously limited. Meanwhile, when the power is cut off due to the force factor, the original digital valve stops working immediately and is difficult to perform function adjustment again. In addition, according to statistics, in the existing hydraulic system, the fault events of the hydraulic system caused by the fault of the valve body account for more than 75%, and it is difficult to determine which specific element has a fault during troubleshooting, and the troubleshooting is performed one by one after all the elements are disassembled during repair, so that the maintenance efficiency is greatly reduced.
Disclosure of Invention
The invention provides a digital valve with flow collection monitoring, fault self-diagnosis, energy recovery and remote communication functions, which mainly comprises a micro generator (5), a control panel (2), a motor (3), a valve body (4) and a storage battery (1). By means of the characteristic that kinetic energy exists in the hydraulic system due to liquid flowing, part of kinetic energy of hydraulic oil in the hydraulic system which normally works is collected, on one hand, the effect of reducing energy loss in the flow adjusting process is achieved, and the energy loss generated by the original flow adjusting process can be collected and stored for the digital valve to adjust. The blades of the micro generator (5) can generate rotary motion under the impact action of liquid flowing, so that kinetic energy is generated for the micro generator (5), the kinetic energy generated by the blades is converted into electric energy by the micro generator (5) and is output to the control panel (2), and the control panel (2) processes the obtained current according to a preset program. The current has two main functions, one is used as a signal to provide a basis for flow monitoring and fault diagnosis (firstly, the current is detected and compared to judge whether the digital valve has a fault, if the digital valve has the fault, an alarm signal is sent, and if the digital valve is normal, the real-time flow passing through the digital valve is obtained through processing according to the magnitude of the current). The other type is that the electric energy is stored in the storage battery (1) as the electric energy, the electric energy is supplied to the storage battery (1) in real time in the working process of the digital valve, and when the electric energy is stored to supply the digital valve to the power failure caused by external interference, the electric energy stored in the storage battery (1) can be used for supplying power for the working of the digital valve in time so as to maintain the normal working of the digital valve for a period of time.
The specific technical scheme is as follows:
the digital valve is arranged in a required hydraulic loop, the hydraulic loop works according to requirements, and at the moment, hydraulic oil flows through the digital valve to drive blades of the micro-generator (5) to rotate to generate kinetic energy. Further, the micro generator (5) converts the kinetic energy generated by the blades into electric energy to be transmitted to the control panel (2). Further, the control panel (2) receives the current passing of the micro generator (5), and judges the current according to the designed circuit and program operation scheme. Further, the control panel (2) outputs information such as the fault of the digital valve, the flow and the like according to the current. Furthermore, the control panel (2) processes current and voltage and transmits the processed current and voltage to the storage battery (1), and the kinetic energy of the hydraulic oil is converted into electric energy and then converted into chemical energy of the storage battery (1) for storage. Furthermore, when the external power supply of the digital valve is stopped, the power supply of the control panel (2) is provided by the storage battery (1), so that the power supply in an emergency is realized.
The invention is mainly characterized in that:
(1) aiming at the conditions that the external power supply of the digital valve fails and stops supplying power, the invention realizes the emergency adjustment of the digital valve by depending on the electric energy converted and stored from the kinetic energy of the hydraulic oil when the hydraulic system works normally.
(2) The invention realizes that the power generation is realized and is supplied for self utilization only by the elements of the digital valve without external power supply, and the redundant electric energy is stored by the storage battery and is supplied for use in emergency.
(3) The invention realizes the detection of the flow in the hydraulic circuit without the help of a flowmeter, and greatly reduces the design and manufacturing cost of the hydraulic system.
(4) The invention provides great convenience for the overhaul and maintenance of the hydraulic system, the fault part in the hydraulic system is very easy to determine, and the maintenance cost and time are reduced.
