Schematic Reading Tips Identify Blocks. Truly expansive schematics should be split into functional blocks. There might be a section for power input and voltage regulation, or a microcontroller section, or a section devoted to connectors. Try recognizing which sections are which, and following the flow of circuit from input to output.

23/05/2012· When reading a flow curve, first identify the range of flows that you can expect to see in your system. Mark these on the graph. Then, look to see what the corresponding changes in outlet pressure will be. Is that range of pressures acceptable to you? If not, you need to look for a different regulator.

The flow-duration curve is a cumulative frequency curve that show the percent of time specified discharges were equaled or exceeded during a given period. It combines in one curve the flow characteristics of a stream throughout the range of discharge, without regard to the sequence of occurence. If the

Speed regulation refers to the undesirable slow down of the motor when it picks up a load. It is an indicator of how well the motor will perform under changing loads and how wide an adjustable speed range can be covered satisfactorily. Speed regulation is not a fixed characteristic of a motor which can be catalogued.
Chat OnlineA pressure reducing regulator is commonly used to manually control pressure of a liquid, gas or steam. Choosing the right regulator for your application can be challenging. There are 5 variables required to size any pressure regulator and properly calculate Cv: upstream pressure, downstream pressure, flow range, temperature and fluid type.

Refer to the flow rate curves of each pressure reducing valve, given in the technical documents. 4 PRESSURE REDUCING VALVES •In 1876 : Invention, manufacturing and marketing of the first regulator. It was somewhat complicated, took up a lot of space (nearly 2 metres high), but it worked. •1930 : A half century had already gone by.

Regulator Flow Curves. Swagelok offers a variety of efficient pressure regulators that, along with other flow control products like gauges and transducers, help you maximize and measure the productivity of your fluid system. To select a pressure regulator, flow curves will allow you to select the option that works best for your requirements.

A regulator’s main purpose is to maintain steady pressure in a fluid system application across the full range of anticipated flow rates. To help confirm that your regulator is sized appropriately, consult its flow curve, which represents the range of pressures the regulator will maintain, given certain system flow rates.

A pump curve provides a wealth of information regarding the performance capabilities of a pump. Information is plotted on an x-y graph where the x-axis is measured in units of flow and the y-axis is measured in units of head, power, and NPSHr. For the sake of example, today we’re going to look at a selection made for the following design ...

Chat OnlineIt starts with a simple graph. The vertical axis shows the amount of pressure on the downstream side of the regulator. The horizontal axis shows the flow rate. When you plot the pressure that the regulator can maintain at various flow rates, you end up with the flow curve. You''ll get a different curve for each set pressure.

of the regulator’s design. A flow curve illustrates the regulator’s range of capabilities at a glance. Once you understand a flow curve – and we’ll explain how – it is easy and very quick to read. Unfortunately, a more common way to select a regulator is to consult its flow coefficient (v). If the system flow is within range C
