What is the anti-disturbance method of the four-column hydraulic press?

The development of the four-column hydraulic press industry is indeed very good today. There are naturally many debates about the four-column hydraulic press. Of course, most people may be worried about the anti-disturbance method of the four-column hydraulic press. Today WORLD Press Machine Shanghai WORLD Press Machine is here to answer your questions.

1. The physical barrier method increases the distance between the disturbed circuit or equipment of the four-column hydraulic press and the disturbance source. Since the disturbance intensity is inversely proportional to the square of the interval, increasing the interval between the disturbance source and the disturbed circuit as much as possible will greatly reduce the disturbance. The transmission will also reduce the failure rate of the hydraulic system, especially in the environment of harsh power supply. Shanghai WORLD Press Machine recommends that you use a stable power supply. An isolation transformer directly connected to the numerical control device.

2. Shielding method, in order to prevent the four-column hydraulic press and components from being affected by the external electromagnetic field, the blocking and shielding method is generally used. The electrostatic shielding is used to eliminate the disturbance between the circuits due to the sub-capacitance sum. The use of ferromagnetic materials with high magnetic permeability can complete the shielding, constraining the magnetic field lines in the shielded conductors with small magnetic resistance, and the use of twisted pairs can also eliminate such disturbances; electromagnetic shielding can withstand or eliminate electromagnetic waves by means of reflection or absorption.

3. Grounding method, the four-column hydraulic press connects its outer casing to the ground for protection grounding. If the four-column hydraulic press system ground wire is connected to the ground for the system grounding, it can also achieve the purpose of anti-interference by means of protective grounding or system grounding.

4. The filter can suppress the input disturbance and various disturbances induced on the signal transmission line. The commonly used low-pass filters and DC filters are generally installed between the power supply of the four-column hydraulic press and the numerical control equipment. After reading the anti-disturbance method of the four-column hydraulic press above, have you increased your knowledge reserve in this area?

Nowadays, the adoption of mechanical power press in automatic power press machine industry is quite common.

Energetic, optimistic entrepreneurs often tend to believe that sales growth will take care of everything, that Shanghai Yingxin World Machinery Co., Ltd. will be able to fund our own growth by generating profits.

But we do think that reckoning with supply chains of mechanical power press is a really important step. Even super simple switches in material, or sourcing, or shipping, or worker benefits seems like good place to start.

[拓展名称] include a great variety of devices with a wide range of complexity: from simple automatic power press machine used since prehistoric times to the complex of modern mechanized automatic power press machine.
