The Hazards Of The Dry Start Of Hydraulic Motors

There are several reasons why you should never dry start a hydraulic motor:

1. Insufficient lubrication: 

When you start a hydraulic motor in a dry state, the internal components do not receive sufficient lubrication. 

Lack of lubrication can lead to friction between the components, resulting in heat generation. 

This can shorten the lifespan of the motor.

2. Component damage: 

hydraulic motors are composed of precision components. 

Starting the motor in a dry state can subject the components to impact and potential damage. 

This can particularly affect the drive shaft and bearings.

3. Air entrapment: 

Starting the motor in a dry state can cause air to be trapped inside the motor. 

Air entrapment can degrade the motor's performance and lead to issues during operation.

4. Difficulty in starting: 

Starting the motor in a dry state can make it difficult for the motor to start smoothly. 

Without sufficient lubrication, the contact between components becomes challenging, 

leading to potential issues during the starting process.

Therefore, it is important to ensure adequate lubrication and avoid dry starting a hydraulic motor. 

Following the manufacturer's recommended guidelines is crucial for the safe operation of the motor.
