Causes and treatment methods of hydraulic press air switch failure

In the daily use of hydraulic equipment, on-duty staff need to pay attention to the operating status of the hydraulic press from time to time to ensure the normal operation of the machine. Today we mainly learn about the treatment methods of hydraulic press air switch abnormalities. The following content is sorted out by experts from Dongguan Jianlong Hydraulic Machinery Co., Ltd., a Chinese intelligent hydraulic equipment manufacturer, for reference:

1. Common causes of failure

1.1 Power supply problem: The power supply is not connected, overloaded or the voltage is unstable, resulting in the air switch not working properly.

1.2 Short circuit or overload: Line short circuit or equipment load exceeds the rated value of the air switch, which will cause the air switch to trip.

1.3 Switch aging or damage: The air switch itself ages due to long-term use, or the switch is damaged due to external factors (such as moisture, dust, etc.).

1.4 Wiring problems: Loose wiring or poor contact may cause the switch to fail to connect or disconnect normally.

1.5 Internal failure: Failure of internal components of the air switch, such as spring failure, contact wear, etc., may cause the switch to fail.

2. Treatment methods

2.1 Check the power supply: confirm whether the power supply is connected normally, check whether the power cord is damaged, and ensure that the voltage is within the allowable range of the equipment.

2.2 Check the load: check whether the load of the hydraulic press exceeds the rated value of the air switch. If necessary, reduce the load or replace the air switch with an appropriate rating.

2.3 Replace the air switch: If the switch is aged or damaged, it is recommended to replace it with a new one in time to ensure its normal operation.

2.4 Check the wiring: Check the wiring of the air switch to ensure that the connection is tight and there is no poor contact.

2.5 Test and repair: For air switches with internal faults, if you have the repair capability, you can disassemble and test them; otherwise, it is recommended to replace them with new ones.

2.6 Regular maintenance: Regularly check the air switch and electrical system to ensure that they are in good working condition and reduce the possibility of failure.

By timely identifying and handling air switch failures, you can ensure the safe and stable operation of the hydraulic press and reduce equipment downtime and maintenance costs.
