Diamond jacking machine power grid shaking prevention device and control method

Abstract

According to the power grid shaking prevention device of the diamond jacking machine and the control method, an emergency lithium battery power supply is additionally arranged on the basis of power supply of an original diamond jacking machine, an electric shaking monitoring module is additionally arranged, and a power grid shaking signal sensor is arranged to monitor a shaking signal of a power grid in real time; according to the device and the method, the power supply of the jacking machine control system can be instantly switched, various problems caused to the control system when a power grid shakes are avoided, meanwhile, the balance control of the lithium battery can be utilized, and the safety of the jacking machine control system is improved. The possibility that large current is generated during charging adsorption and discharging of the battery when a power grid shakes is prevented, and the impact on phase change and power transformation is reduced to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of peripheral power supply equipment of a diamond top press, in particular to a power grid vibration prevention device and a control method for a diamond top press. Background technique [0002] The superhard material industry involves a wide variety of synthetic products, such as synthetic diamonds, diamonds, CBN, composite sheets and so on. [0003] With the development of industry and the improvement of residents' living standards, the superhard materials synthesized by the diamond top press have been widely used in many fields. In recent years, due to the decline in the proportion of the labor force and the rising wages of workers, the production cost has been indirectly increased, which has affected the economic benefits of enterprises to a certain extent. Therefore, it is necessary to adopt advanced production equipment to improve production efficiency and reduce the number of employees to reduce prod...

AI Technical Summary

Problems solved by technology

[0007] When the power grid fluctuates, the sensors in the control system will deviate from the parameters detected by each actuator, resulting in inaccurate parameters and providing an error signal to the control system, which cannot guarantee the effective execution of the synthesis process, reduces the accuracy of the control, and directly affects Synthetic effect, resulting in unstable product quality

[0008] 2. The action execution of the control system is unstable

[0009] When the power grid fluctuates, the relays, contactors, frequency converters, servo drivers, solenoid valves, motors and other executive components in the control system cannot guarantee normal work. If protection occurs, the possibility of continuing to execute actions will be lost, which will affect the effective execution of the later synthesis process and indirectly affect the quality of synthesis. In severe cases, it will cause abnormal phenomena such as low pressure and high temperature. The molds such as the top hammer of the top press are damaged and blasted, causing greater economic losses and increasing production costs and maintenance costs

[0010] 3. The reliability of the control system itself is reduced, and the service life is greatly reduced

[0011] When the power grid fluctuates, the voltage signal provided contains a large number of harmonic components, and some harmonic components and the peak value of the harmonic components will cause fatal damage to the electrical components of the control system, resulting in waste of maintenance materials and increased operating costs. Cost, not conducive to product cost control
