What happens if you over work a Dead Head Regulator?
Some common problems that you might encounter when over-working a dead head regulator include; fluctuating fuel pressure, pressure creep, as well as the possibility of over-powering the carbs needle and seat which can flood your engine and wash the cylinder walls.
How does the resistance of a series regulator work?
The resistance of the transistor to current automatically adjusts depending on the output load, such that the output voltage remains constant at the desired level. In a series regulator circuit the input current has to be slightly more than the output current.
Why do drag racers need a by pass regulator?
By plumbing a by-pass regulator before the carburetor, drag racers can build higher pressure in the feed to help counteract the high g-forces that they experience during hard launches and rapid acceleration.
What are the requirements for a pressure regulator?
The materials selected for the pressure regulator not only need to be compatible with the fluid but also must be able to function properly at the expected operating temperature. The primary concern is whether or not the elastomer chosen will function properly throughout the expected temperature range.
When to use a relieving or non-relieve pressure regulator?
A non-relieving regulator is preferred for use with hazardous, explosive, or expensive gases because the design does not vent excessive downstream pressure into the atmosphere. In contrast to a non-relieving regulator, a relieving (also known as self-relieving) regulator is designed to vent excess downstream pressure to atmosphere.
Which is the best seal material for pressure regulators?
Stainless Steels are often chosen for use with corrosive fluids, use in corrosive environments, when cleanliness of the fluid is a consideration or when the operating temperatures will be high. Equally important is the compatibility of the seal material with the fluid and with the operating temperature range. Buna-n is a typical seal material.
How is excess pressure discharged from a pressure regulator?
In some special designs, the vent port can be threaded and any excess pressure can be vented from the regulator body through tubing and exhausted in a safe area. If this type of design is selected the excess fluid should be vented appropriately and in accordance to all safety regulations.
