The correct way to install this motor

[ali 120]

I am working on a GTO machine
Is it normal?
When the intake hose is inserted, the motor becomes hot. When the intake hose is not in place, it does not heat up

Vacuum for delivery slow down wheels? If air flow is considerably restricted, these regenerative pumps will overheat. There could also be obstruction in intake housing. Obviously, if your slow downs are physically shut down, and there’s no relief valve, you wouldn’t have the pump turned on.

Did you change filters? Clean the air ways . Is cooling fan working.?

Did you change filters? Clean the air ways . Is cooling fan working.?

Yes, the air filters are clean and the air duct is clean
The cooling fan is working
The problem is that the motor starts to heat up when the intake hose is placed in the machine
But when the intake hose is not placed in the motor, there is no heat in the motor

How can I verify what I said?

 

[Jack liston]

Clean the old spray powder out of the slow down wheels in delivery.the powder will build up in wheels and the hoses in delivery. Making pump struggle

It’s not difficult to verify, Ali. By attaching hose to nipple, and pump heats up, that would mean the air flow is being disrupted. Since the pump does not heat up when free running, there should not be anything wrong with it. Have you opened up the 3 toggles that adjust vacuum to the individual slow down manifolds?

check following: Normally, the surface temperature can reach upto 70 degree, so it is normal temperature, and as yon can see, there is YELLOW STICKER showing the HOT area at the vaccume pump.
If the vacuum lines, filters, or ducts are clogged with paper dust, debris, or other contaminants, the motor has to work harder to maintain suction, causing it to overheat.
- Is the motor also getting HOT, Check the Motor Current with AMpare meter:

• when the hose is connected, how many ampares?
• When the hose is not connected, how many ampares?
• 2- Check the following, The ambient and suction temperatures must be between 5 and 40°C.
• Ambient or suction temperature is too hot
• Pressure difference is higher than permitted
• Cooling air flow is restricted
