How do I choose a suction strainer?

How do I choose a suction strainer?

The first thing to determine is the flow rate. Any flow rate over 150 GPM will most likely require a basket strainer because of pressure drop considerations. Strainers are usually sized so that their start up pressure drop is no greater than 2 PSI, with a line velocity not to exceed 8 FPS.

What is open area ratio of strainer?

Open Area Ratio – Open area ratio is the yardstick for determining the length of time a strainer will operate without cleaning or suffer undue pressure loss. This ratio is the relationship between the internal cross sectional area of the inlet pipe and the total open area of the openings in the basket.

How do you measure a basket strainer?

When in doubt about which of two basket screens to use, it is best to choose the larger. As a rule of thumb, size the baskets for one half the particle size to be removed.

How do you calculate the area of a strainer?

Choose the size perforation or mesh needed to remove particles from the media passing through the strainer. 2. Multiply the TOTAL SCREEN AREA by the PERCENT OF OPEN AREA of the screen. The result equals the OPEN AREA of the screen.

How do you calculate pressure drop in a strainer?

The pressure loss across a strainer can be calculated using the system’s flow rate and the Cv factor for that strainer. For example, a 1″ Model 72 simplex strainer with a perforated basket has a Cv factor of 22.5. In water service with a 30 gpm flow rate, it will have a 1.7 psi pressure drop (30 ÷ 22.5)2 = 1.7.

How do you calculate pressure drop across a strainer?

How do you calculate strainer pressure drop?

What is the pressure drop across a filter?

Pressure drop is defined as the change in pressure from one defined area to another. In HVAC, this is referring to the change in static pressure as air moves through your air filters. Put simpler, it’s how much your air filter restricts airflow.

What is pressure drop air filter?

How often should you clean y type strainer?

In general, when the pressure drop across a y-strainer gets to about 5 or 6 psi differential, it’s time to clean it. Never let it get too plugged; for example, more than 10 psi.

What is Y type strainer?

Y-Strainers are devices for mechanically removing unwanted solids from liquid, gas or steam lines by means of a perforated or wire mesh straining element. They are used in pipelines to protect pumps, meters, control valves, steam traps, regulators and other process equipment.

How do you determine strainer mesh size?

Take one square inch of filtering material (screen) and count the holes in it. If you have 80 openings in that area, then you have an 80-mesh screen. If you have 200, then it is 200-mesh and so forth. Therefore, the higher the mesh number, the smaller the particles that are filtered.

How do I choose a strainer?

How to Select a Pipeline Strainer

1. Choose the proper strainer configuration.
2. Identify critical design criteria. Select the materials of construction. Determine the correct particle retention size. Choose a strainer size based upon fluid velocity and differential pressure.
3. Identify installation space constraints.

What is the purpose of a suction strainer?

The purpose of a suction strainer is to act as a particulate strainer or filter ahead of the pump. This prevents large particles from entering the pump.

What is a filter and strainer?

Industrial strainers and filters are designed to remove unwanted particulates from a liquid or gas. Strainers typically remove larger particles that are visible in a liquid or gas, while filters remove contaminants that are often so small, they cannot be seen with the naked eye.

Can you install Y strainer vertical?

Y strainers are a valuable addition to many piping systems as they can be installed vertically or horizontally. Add that to the fact that they can be used to transport steam, gas, or liquid, they are an excellent choice for a strainer.

What is the difference between a filter and a strainer?

The key difference between strainers and filters are the size of the particles they remove. Strainers typically remove larger particles that are visible in a liquid or gas, while filters remove contaminants that are often so small, they cannot be seen with the naked eye.

How does a strainer work?

By definition a strainer provides a means of mechanically removing solids from a flowing liquid. They do this by utilizing a perforated metal, mesh or wedge wire straining element. If you add a blow-down valve the strainer can be flushed without stopping the flow through or disassembling the piping.

What are the similarities of filter and strainer?

Filters and strainers do have a lot in common. Both products are designed to remove suspended particles from a liquid or gas. They also both deliver similar benefits by protecting downstream equipment and removing impurities or contaminants that might compromise the quality or integrity of the product.

What does a hydraulic suction filter do?

A hydraulic filter helps to remove these particles and clean the oil on a continuous basis. The performance for every hydraulic filter is measured by its contamination removal efficiency, i.e. high dirt-holding capacities. A hydraulic filter helps to remove these particles and clean the oil on a continuous basis.

What is a hydraulic suction filter?

Role of the Hydraulic Suction Screen. The suction filter is housed internally within the transmission body and it filters and cleans the hydraulic oil of debris, metal flashing, filing from the gears, dirt, rust and other junk. The filter medium is a mesh stainless steel screening and a lot of oil passes over it every minute.

What is a hydraulic suction line?

And a hydraulic pump suction line is a very special place, where the maximum flow-driving positive pressure is a fixed value, defined by the sum of the oil head above the pump inlet and the internal tank pressure. This pressure is usually very low, especially in atmospheric and low profile tanks.
