Source: http://romtecutilities.com/ LIFT STATION Wastewater treatment is an important process, used for removing contaminants from wastewater so it could be discharged back into the water cycle with minimum impact on the environment. Drainage systems were invented during the Ancient Rome times. They consisted in surface conduits that were used to collect drainage water and spill it [...]
Why is it important to descale? 1 Periodic descaling helps prevent Legionnaire’s disease bacteria. Cooler tubes often become caked with algae, mud, scale and sludge. These also develop in the water that accumulates in a cooling tower’s basin floor. Unfortunately, Legionella bacteria thrive in this environment. Descaling would remove the scale, sediments, and slime [...]
Descaling is the removal of limescale for industrial and domestic water users in hard water areas. What is hard water? It’s a water that has high calcium or magnesium ions content (>≈ 1.2 mM ) acquired during its passage through calcium or magnesium-containing rock such as limestone or chalk. The amount of dissolved calcium [...]
How to Maintain Gate Valves One of the best ways to ensure your Valves will work properly, is doing regular maintenances to them. Follow this tips to have fully functioning Valves Use Lubrication. Over time a steel gate valve can begin to stick. If a problem were to occur and [...]
There are various factors on how to classify gate valves, such as (1) Disks; (2) Body Bonnet Joint; and (3) Stem movement. Type of Gate Valves based on disk: Solid Wedge – It is the most common & widely used disk types because of its simplicity and strength. A valve [...]
Now that we have some basic knowledge of what a Gate Valve is and how it works, let’s see how it is made and its parts. Body – it is also called This is the primary pressure boundary of a valve. It serves as the principal element of a valve assembly because [...]
GUIDELINES TO PURCHASE AN ACTUATORConsider these variables when purchasing your actuators.Consider the motion profile. This will determine your need on minimum and maximum speed requirements.Load calculation. It is important to consider different components like friction load, inertial load, the external applied load and others. Note: calculations will also depend on the orientation of the actuator.Duty [...]
TIPS ON HOW TO CHOOSE ACTUATORS Knowledge on parameters such as loading, stroke length, timing, and others, are important in picking powered actuators. Many of these parameters have limits as to speed and force and narrowing the selection in this manner can bring the appropriate technology into focus. It also needs to keep in [...]
Electric Linear Actuators are electrically powered, mechanical devices consisting of motors, linear guides, and drive mechanisms, used to convert electrical energy into linear displacement through mechanical transmission, electro-magnetism, or thermal expansion to provide straight line push/pull motion. They are used in a wide range of industries where linear positioning is needed. The actuators are driven [...]
Previously, we talked about what an actuator is, and we can now start to see the different types of Actuators Thermal actuators are actuators that convert thermal energy into movement. One type of thermal actuator is a bimetallic strip, a strip made from two different metals such as steel and copper. [...]
