In today's intelligent manufacturing environment, the use of Full Automatic Hydraulic Machine is more and more extensive, of course, the operation and maintenance work is also very difficult. However, machine tool electrical equipment in the actual operation process often appear some inexplicable failure, in addition to the aging or quality of the machine tool itself, regularly check the quality of power supply, temperature and other inspection, according to the test results can be planned maintenance.

Here are some common considerations:

1. Power supply quality

From the point of view of electricity consumption, the voltage, current or frequency deviation that leads to the failure or failure of electrical equipment is power quality. In addition, some loads will also affect the quality of the power grid during operation, injecting harmonics, causing power grid voltage fluctuations, affecting the operation of nearby loads, etc.

The problem of power supply quality will not only affect the normal and continuous operation of the electrical equipment, but also affect the operation efficiency. Full Automatic Hydraulic Machine has very high requirements on the quality of power supply, for example, the voltage amplitude with the load change to ensure a certain stability, otherwise it will cause a variety of misactions, the harmonic content can not be too large, otherwise it will overheat, reduce the insulation performance of the equipment, and three-phase imbalance.

In daily work, we often do a physical examination of the power supply quality of key equipment, find anomalies (excessive harmonics, three-phase imbalance, large voltage fluctuations, etc.), and take countermeasures to avoid production losses caused by downtime and damage to important production equipment.

2, insulation performance

There are generally oil mist, dust and metal powder in the air in the machining workshop, once they fall on the circuit board or electronic devices in the CNC system, it is easy to cause the insulation resistance between the components to decline, and even lead to damage to the components and circuit boards.

In the daily maintenance of Full Automatic Hydraulic Machine, it is necessary to test the insulation performance of drive motor and cable regularly. The use of digital insulation meter can greatly improve the maintenance efficiency.
