First level agent NEXEN original 964860 spot clutch brake pads

The common faults and maintenance methods of the brake include the following:

1. Brake failure:

Reason: Short circuit of motor winding, malfunction of motor brake electromagnet, malfunction of motor brake power supply, etc.

Solution: Check and repair the motor winding short circuit, replace the electromagnet, check the power circuit and switch, and repair the fault.

2. Overheating of the brake:

Reason: Overheating of motor brake electromagnet, overload of motor brake power supply, etc.

Solution: Check if the electromagnet is overheated and replace it in a timely manner, check the power load and upgrade the power supply.

3. The brake noise is loud:

Reason: Motor brake solenoid malfunction, motor brake pad wear, etc.

Solution: Replace the electromagnet and brake pads.

4. Brake switch malfunction:

Reasons: switch aging, accumulation of dust and dirt, circuit failure, improper installation, etc.

Solution: Replace the aging switch, clean the interior of the switch, repair circuit faults, and reinstall the brake switch correctly.

5. Brake coil malfunction:

Reason: coil open circuit, short circuit or insulation layer damage, brake pad wear, spring failure, control circuit problem, power supply problem, etc.

Solution: Check and replace damaged brake coils, brake pads, or springs, and repair control circuit and power supply issues.

6. The brake cannot be opened:

Reason: Insufficient or poor lubrication, impurities entering the brake, spring fatigue or damage, inaccurate installation position, aging of components, etc.

Solution: Add or replace lubricating oil, clean the interior of the brake, replace fatigued or damaged springs, adjust installation position, and replace aging components.

Separate not

Fault manifestation: After disconnecting the power, the clutch still has some power transmission, causing the equipment to be unable to stop or difficult to shift gears.

Core reason:

a. The height of the separation lever is inconsistent and the force is uneven, resulting in the inability to detach.

b. The separation bearing is stuck or damaged, making it impossible to push the separation mechanism into place.

c. The clutch driven plate is warped and deformed, and cannot be separated from the driving plate.

Solution:

a. Adjust the separation lever to ensure that all lever heights are consistent and the error is controlled within the specified range.

b. Check the separation bearing. If it is stuck or worn, clean and lubricate it or replace it directly.

c. Check the flatness of the driven disc. If it is warped beyond the tolerance, replace it with a new driven disc.

4. Clutch overheating

Fault manifestation: After running for a period of time, the shell temperature becomes too high (usually exceeding 120 ℃), and even smoke appears.

Core reason:

a. Long term semi clutch operation generates excessive heat due to friction.

b. Poor heat dissipation, obstructed ventilation around the clutch or damaged heat dissipation structure.

c. The friction plate material is unqualified and has poor high temperature resistance.

Solution:

a. Optimize the operation process, avoid prolonged semi clutch operation, and reduce unnecessary friction losses.

b. Clean up the debris around the clutch, check whether the cooling fan and cooling holes are normal, and ensure good ventilation.

c. Replace with high-temperature resistant friction plates that meet the equipment requirements and avoid using inferior substitute parts.

Normally closed pneumatic brake is a braking device driven by compressed air, mainly used for safe braking of mechanical equipment. Its working principle is to control the closure of the friction block through a cylinder, and quickly lock the brake disc with spring force when the air is cut off, achieving stable braking. ‌

Main functions

Safe isolation: using pneumatic control, isolated from the power supply to avoid equipment damage caused by electrical faults. ‌

Quick response: When the air is cut off, the spring quickly locks and the braking response time is short. ‌

Wear resistant and durable: The components are made of wear-resistant materials, which have a long service life. ‌

Typical Applications

Suitable for industrial scenarios such as metallurgy, chemical engineering, and textiles that require frequent start stop operations, ensuring safe shutdown of equipment. ‌

Product features

Maintenance free design: Some models adopt a maintenance free structure to reduce maintenance costs. ‌

Energy saving and environmental protection: Pneumatic drive has no additional energy consumption and reduces motor load. ‌

2、 Daily preventive maintenance suggestions

1. Regular inspection: According to the equipment maintenance cycle, check key parameters such as friction plate wear, spring elasticity, and gap size.

2. Cleaning and lubrication: Regularly clean the oil and debris inside the clutch, and add lubricating medium to the transmission components as required.

3. Standardized operation: Train operators to avoid illegal operations, such as frequent semi clutch and overload operation.

4. Spare parts management: Reserve key spare parts (such as friction plates, bearings, springs) to avoid prolonged downtime due to missing parts after failures.
