At very low suction pressure, the suction valves of reciprocating compressor will not work and there will be no gas in the cylinder during compression stroke, resulting some damage to the suction valves. If low suction pressure trip protection is not provided there can be some abnormal damage.
Suction lift is only negative. Suction head is positive or negative.Suction head is the distance between the surface of the liquid being pumped and the centerline of the pump. It can be positive or negative, and it can be affected by pressure or vacuum on the surface of the fluid. A negative suction head is also called suction lift.Example 1: A D/A under 15 psig is set 20 feet above the feed pump the effective suction head is 54 feet. (15 psig is equivalent to 34 feet of water).Example 2: A Condenser hotwell under 28 inches of vacuum (Hg) is set 16 feet above the suction of a propeller pump. The effective suction head (lift) is -15 feet.* (28"Hg = - 31 feet of water)Example 3: A sump pump is set 4 feet below the surface of the well. The effective suction head is 4 feet.*Note: Suction lift is only effective to a maximum of 21 feet, and 15 feet for hot water depending on temperature and pump slip.
when pressure on the suction side of the pump drop below the vapour pressure of the liquid, vapour forms. It's caused because of insufficient suction head, high suction lift, excessive friction head, or high liquid temperature.

...It will be what ever your suction pressure is.
Types of suction items are suction cups, suction hooks, and suction hoses.
The opposite of a compressor. A vacumn cleaner is a suction device. Were you ever on a baby bottle. You used suction to get the formular out of there. A suction machine sucks!
No, they don't have suction on their head
history of suction macine
Using suction.
Discharge side........
The base word of suction is "suck."
Cut a potato, rub the juice on the suction cup. This really does work. I don't know why.
They don't have suction cups they have tube feet
The vacuums that do not lose suction is the Dyson vaccums.
A single suction pump having its suction nozzle on the opposite side of the casing from the stuffing box and having the face of the suction nozzle perpendicular to the longitudinal axis of the shaft
they all have suction cups. There are eight tentacles and two arms(they all have suction cups). Hope this helps!
