Your reciprocating compressors have to be the booster compressors (if running on low temp system)feeding its discharge to the suction of the screw(not directly)(if running on medium temp.
A rotary compressor is like a car engine, with pistons, rods, sleeves, valves, etc. A screw compressor has two screw type rotating parts that squeeze the refrigerant as the screw threads get tighter and tighter. They have long life potential.
Answer: The terms suction and discharge are the terms refer to hydraulics. In hydraulics if the the liquid has to be lifted or pumped to the usage area the hydraulic pump will be used . This pump will have to functions that is first suction to lift the fluid and the discharge or delivery . The familiar words in pair are lift and discharge; suction and discharge. The specification of pump for these terms are suction head and discharge head.AnswerThe suction pressure refers to the pressure of the referigerant being "sucked" back into the compressor. The suction pressure is a critical variable in ensuring the accuracy of the refrigerant charge, along with the tepmerature of that line as well. The "superheat", or heat added to the vapor in that line can be monitored in this manner.You have not mention which suction pressure... Actually Where ever the suction is presented that pressure is called suction pressure.... and suction pressure in practical cases normally always less that atmospheric pressure and in case of delivery pressure it is oppositeSaying that suction pressure is " the pressure of the referigerant being "sucked" back into the compressor " is not accurate.Simply , the suction pressure of a pump is the absolute pressure of a fluid , measured at the inlet of the pump ( in your answer , the pump is the compressor , and the fluid is whatever refrigerant. )The discharge pressure , is the absolute pressure of the liquid measured at the outlet of the pump.Obviously, the discharge pressure is usually bigger than suction pressure.
As the reciprocating pump operates though the reciprocation of the follower,it guides the suction and the compression of water in the pipe.That's so when the rotary motion of the rotor blade is converted into the reciprocating motion, which deliver it to the reciprocating pump, the suction and discharge takes place.
diaphrams are static ones containing guide blades...steam from suction end enters the suction diaphragm and get guided to impeller of centrifugal compressor..ntermediate diaphrams contains diffusers which changes pressure energy..these daphragms forms a part of inner casing.
...It will be what ever your suction pressure is.
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.
Snubber is Pulsation damper that is installed on suction and discharge of compressors. It provides a continuous stream on reciprocating compressors.
Pressure increases due to load(or heat intake from evaps).if asking about off cycle. If asking about compression cycle,its the compression of vapor into a higher pressure side of system along with heat of compression adding to temp-pressure relationship.

The suction line connects the evaporator outlet and the compressor intlet. Low pressure refrigerator vapour is drawn from the evaporator to the compressor through this line.
To provide moisture free compressed air to a pneumatic system that operates pneumatic motors.

High head pressure; low suction pressure; overheated compressor

An A/C compressor sucks refrigerant gas from the evaporator inside the car and compresses it into high pressure liquid. So the tubing that goes from the evaporator inside the car to the compressor is called the suction line.
It will be on the suction line (larger of the lines) between the compressor and the evaporator.
