Clearances in piston rings

Axial Clearance: It is the clearance between the ring and the groove to be measured at the top part by a feeler gauge. This clearance is to be measured at four different points for each ring. Radial Clearance: The radial clearance is the difference between the groove depth and ring width, which can be measured by a vernier caliper

6 FAQs about [Generator air guide ring matching clearance]

How far can a Generac air cooled generator be mounted?

Generac air-cooled generators may be mounted within 18 inches of a house, but must still maintain the 5 foot rule for operable windows and doors. There are no specific parameters given for the actual enclosure fire test. Generator must have adequate air flow. A good rule of thumb is 5 feet, although smaller generators may not need this much.

How much clearance does a generator need?

5ft. from openings in walls (operable windows, doors, vents, window wells, or openings in the wall). 18 in. of clearance from the back of the generator to a stationary wall or building (based on testing done by the Southwest Research Institute or SwRI). 5 ft. of clearance above the generator. 3 ft. of clearance at the front and both ends.

Can ABB air gap Inspector be used on a generator?

It can be used in all motors and generators with air gaps of 10 mm and upwards. Unlike conventional inspection devices, which are restricted to turbo/hydro generators with very large air gaps, ABB Air Gap Inspector can be used on all large synchronous motors and generators with air gaps of 10 mm or more.

How do you check the clearance between gates?

With the gates closed, check the top and bottom clearances between - the gates and the facing plates and the clearances between the gates. The heel and toe sides of the gate should both be measured when checking the top and bottom clearances. In checking the clearances between gates, check the clearance at the top, middle, and bottom.

What should be taken in a generator rotor test?

Top and bottom seal ring clearance should also be taken. Generator air gap.-Air gap readings should be taken at least in four quadrants and at the top and bottom of the rotor. For better accuracy in determining the position of the rotor in the stator and for determining the shape of the stator, more readings may be required.

What are the NFPA requirements for a generator?

Its requirements limit the spacing of the generator from a structure or wall. The unit must be located where it’s readily accessible for maintenance, repair, and first responders. Minimum clearance requirements are for adequate airflow, maintenance, and safety. For a complete and updated list, see the NFPA 37 web page.
