Description

technical field [0001] The invention belongs to the field of solenoid valve driving, and specifically refers to a solenoid valve driving device and a driving method thereof. Background technique [0002] During the production and roasting of anode carbon blocks, the gas supply needs to be precisely controlled. During the gas supply process, the gas supply needs to be adjusted in real time according to the actual production situation and demand. In the current industrial production process control system, The adjustment process is generally done through a solenoid valve. In today's production equipment, the solenoid valve of the terminal control equipment is generally driven and controlled by a relay, and the relay is generally controlled by the control system according to the production process parameters, thereby achieving the effect of controlling the on-off of the solenoid valve. [0003] The main feature of this control method is that the solenoid valve needs to work at...

Problems solved by technology

[0003] The main feature of this control method is that the solenoid valve needs to work at full power all the time, which greatly increases the energy consumption of the product, leads to an increase in the heat generation of the equipment, and thus greatly increases the failure rate of the equipment. Maintain and repair the equipment, which greatly improves the cost of using the product

In addition, the response time of the relay is slow, which has a certain impact on the normal production process of the equipment; when the contacts of the relay are closed or disconnected, an arc will be generated, which will cause electromagnetic interference to the digital signal system and affect the normal use of the digital signal system; At the same time, the entire device lacks overload and short-circuit protection, and there is no fault indication structure, which is not conducive to the protection of the use of the device, and it is difficult to repair the device in time when it fails

[0004] To sum up, the research and development of the driving method and device of the solenoid valve of the terminal control equipment is to overcome the problem of high energy consumption and high heat generation caused by the high power consumption of the solenoid valve when it is always working at full power. very necessary
