suction line

[′sək·shən ‚līn]
(engineering)
A pipe or tubing feeding into the inlet of a fluid impelling device (for example, pump, compressor, or blower), consequently under suction.

The self-priming centrifugal, a specialized end suction pump design, creates a vacuum at the impeller eye to continuously remove air from the suction line. The pump is not capable of compressing the air during the priming phase and it must be allowed to escape through the discharge.
Hydra-Cell Q155 Series pumps can operate with a closed or blocked suction line and run dry indefinitely without damage, eliminating downtime and repair costs.
In addition to zero leakage, the pumps can run dry without damage, will operate with a closed or blocked suction line, and can pump abrasive fluids effectively.
The suction line housing is placed higher on the pump, allowing the empeller and mechanical seal to be covered with water at all times, eliminating the need to reprime the pump and protecting the seal from running dry.
The Vortex pump technique developed by Wemco is based on the principle of a whirlpool: a vortex is created by the rotating, recessed impeller, extended into the suction line, drawing the liquid solids into the pump and then quickly through the discharge, whilst minimising the fluid / solids contact with the impeller and volute.
After this step the cleaned bilge water with less then 15 ppm of oil is lead back through a three-way valve into the present OWS suction line and is pumped overboard through the existing OWS and controlled by the present oil content metre.
Similarly, also in this case, the P-h diagram shows that there is a continuous fall of enthalpy throughout the process of expansion on account of heat transfer from the capillary tube to the suction line. The refrigerant usually enters the capillary tube in a subcooled state, and the pressure drop causes the flow through the capillary tube divided into two distinct regions--the single-phase liquid region in the initial part, and the two-phase liquid-vapor region in the remaining part.
In a diabatic capillary tube, the capillary tube is bonded with the cold compressor suction line to form a counter flow heat exchanger.
Ensure the suction line insulation is continuous and serviceable.
Just connect the quick disconnects to the suction line to the heater and turn on the heater's electrical system to start the fuel pump.
The R Series valves can meet needs for all HVACR applications including liquid line, hot gas discharge, and suction line requirements.
Pick-up Suction Line Strainers are corrosion-free plastic filters that eliminate contamination on pick-up lines for air, vacuum, liquid or oil applications.
