Cavitation in pumps and valves, a common occurrence caused by rapid pressure drop and flashing of fluids, is sometimes difficult to describe. This video provides an excellent visual and audible demonstration of the conditions leading up to fluid flashing and subsequent cavitation.

A properly designed steam system is extremely important. Clean, dry steam through your steam distribution network maximizes the quality of steam, and protects all related components thus keeping costs and maintenance to a minimum. Principles of Operation of the Pressure Reducing Valve: - Normal positions before start-up are with the main valve closed and the pilot valve held open by spring force or air pressure. Entering steam passes through the pilot valve into the main diaphragm chamber and also out through the control orifice. As flow through the pilot valve exceeds flow through the orifice, control pressure increases in the diaphragm chamber and opens the main valve. As steam flows through the main valve, the increase in downstream pressure feeds back through the pressure sensing line to the underside of the pressure diaphragm. When the force below that diaphragm balances the compression force of the spring above it, the pilot valve throttles. The control pressure maintained in the main diaphragm chamber positions the main valve to deliver just enough steam for the desired delivery pressure. Adjustment of the spring or air pressure above the pressure diaphragm changes the downstream pressure set point. When steam is no longer required, the sensing line pressure increases closing the pressure pilot and the control pressure bleeds back through the control orifice. This allows the main valve to hold the desired reduced pressure, and it may close tight for a dead-end shutoff.

This video illustrates how a bimetallic steam trap works. It shows the thermostatic principal involved and how two bimetallic plates interact and provide physical movement to open and close a valve seat to discharge condensate. Bimetallic steam traps are used in many industrial and commercial applications in the chemical processing, energy production, food processing, HVAC, pulp and paper, mining, petro-chemical and pharmaceutical industries.

According to Wikipedia, water hammer is defined as "a pressure surge or wave caused when a fluid (usually a liquid but sometimes also a gas) in motion is forced to stop or change direction suddenly (momentum change). A water hammer commonly occurs when a valve closes suddenly at an end of a pipeline system, and a pressure wave propagates in the pipe. It is also called hydraulic shock." When improperly drained of condensate in a high pressure steam main fills with condensate and completely surrounds the steam, an implosion takes place causing devastating water hammer. Draining condensate and keeping it away from the steam by using proper steam trapping equipment will prevent this from happening. The following video, courtesy of Spirax Sarco USA, dramatically demonstrates the principle behind water hammer and its potentially devastating effects.

Regenerative turbine pump has double row vanes cut in the rim. The impeller rotates within two liners into which annular channels have been milled. Liquid flows in at the suction and is picked up by the impeller vanes. In completing nearly one revolution in the annular channel, the fluid develops a high velocity and pressure increases dramatically before being sent out the discharge. The liquid re-circulates between the impeller vanes and the annular chamber. Because of this action, the fluid flows in a path like a helical spring laid into each of the annular grooves as the fluid is carried forward. Energy is added to the fluid by a number of vortex impulses in the impeller vanes, as it travels from suction to discharge. These impulses have the same effect as multi- staging in a centrifugal pump. In a multistage centrifugal pump, the pressure is the result of energy added in each stage. In a turbine pump, pressure is added to the fluid stream by circulating many times through the vanes of a single impeller. One of the most remarkable features of the regenerative turbine pump is its performance characteristics when pumping highly volatile liquids. The manner in which the turbine impeller imparts velocity/energy to the fluid, as described above, is quite different from conventional centrifugal or positive displacement designs. The continuous, progressive building of pressure in a regenerative turbine pump essentially eliminates the sudden collapse of bubbles that is destructive cavitation. A turbine pump can develop about ten times the discharge pressure of a centrifugal type having equal impeller diameter and speed. Pressure increases nearly uniformly around the impeller rim. At the impeller hub, the pressure is about one half the discharge pressure. This lower pressure, plus suction pressure, is what is seen in the stuffing box. Holes through the impeller keep the impeller centered to reduce wear, prevent unbalanced pressures on the impeller and reduce end thrust on the bearings.

A quick video showing the basic operation of a metal body, diaphragm valve for industrial applications. The video illustrates how the metallic lower valve body is machined for a smooth controlled flow characteristic, and how the elastomer diaphragm is controlled by the liner movement of the valve stem. Full open, full closed, or proportional flow is controlled by the relationship of the valve diaphragm and valve body. Metal body diaphragm valves are available in many metal alloys such as brass, cast steel, and 316 stainless steel, with many different elastomers including EPDM, PTFE and Viton. These valves are great for inert and corrosive liquid and gaseous media, are highly resistant to chemicals, are insensitive to particulate media and offer a compact design (ideal when space is at a premium).

There are several types of check valves. This video introduces the viewer to the swing check valve. The swing check uses the directional flow to push open a swinging disk. As long as flow continues, the disk stays raised. But as flow stops, gravity allows the disk to re-seat itself and any reverse flow is prevented by the closed disk. As reverse flow pressure increases, the swing check valves seating increases as well.

The Crane®FKX 9000 Triple Offset valve design is recommended for industrial applications where large bore valves handle hot steam or isolate parts of their plants and have high/low temperatures that prevent the use of rubber lining elements. Here's an explanation of "Triple Offset" Offset One This offset applies to the center line of the disc/seat sealing surfaces that provides an uninterrupted sealing surface. Offset Two This offset refers to the location of the shaft with respect to the center line of the bore, which enables a calming action of the disc to minimize rubbing and wear between the seat and seal. Offset Three This offset is the axis of the seat cone angle that is offset from the center line of the valve bore to eliminate rubbing of the seat/seal contact surfaces during operation and to preserve sealing integrity over the cycle life of the valve.

The definition of "explosion-proof" doesn't mean the enclosure can withstand the forces of an external explosion, but rather that it will cool any escaping hot gases (caused by an internal spark or arcing contacts) sufficiently enough as to not to allow the ignition of combustible gases or dusts in the surrounding area.

https://mnteng.com 303-232-4100 An evaporative cooling tower is heat removal device that uses ordinary water to transfer process waste heat from building and equipment into the atmosphere. All cooling towers operate on the principle of removing heat from water by evaporating a small portion of water that is recirculated through the unit. The mixing of warm water and cooler air releases latent heat of vaporization, causing a cooling effect to the water. Cooling towers are a key component of many refrigeration systems and can be found in industries such as chemical processing plants, power plants, steel mills, food processing plants, and many other manufacturing companies where process cooling is required. Cooling towers are also used to provide comfort cooling for large commercial buildings such as universities, government facilities, airports, schools, hospitals, and hotels. https://mnteng.com 303-232-4100
