Torque limiting

What type of pressure switch?

How does the crank wheel adjust the torque?

If you are talking about controlling torque on a electric motor, you can try using a inverter.

Hi,

Probably the simplest mob would be to over drive the final drive by 2 to 1. This would approx halve your available torque. also if you increase the ratio of the final drive, you could increase the output torque.

If the motor is an AC induction type, you could try playing around with the input voltage using a variac(variable transformer).

You could also play around with the spring inside the pressure switch. I am involved with pressure washing machines and we get different pressure trips by using different springs.

Hope it helps.

Hi Guest,

You said: "I am involved with pressure washing machines and we get different pressure trips by using different springs."

Since you brought this up, I have a question. Is there an easy way to check/adjust/set the bypass spring tension on a pressure washer pump? The spec plate on my unit says it is a 2500 PSI unit. I think the previous owner may have tinkered with the spring tension so I don't really know if the pressure is what it should be.

Any suggestions?

Thanks,

John

dear sir,

first of all let me know for press fitting what type of machinary you are using if it is hydualic /pnumatic then the best solution is multiport (as per ur m/c req.) proportional solenoid valve with digital pressure controller having analog output i.e 4-20ma ,0-10vdc or 0-5vdc if you are using ac motor with suitable mechanical adds i.e.

gear ,sprokets,ratio pully or cam then ac drive with variable torque will be well suitable for ur application.for more details pl. do not hesitat to contact us our mail is gopala1967@rediffmail.com.
