Insulin aspart can be used in an insulin pump and insulin pen for subcutaneous injection. Additionally, it can be used with an injection port such as the I-port. [25] Insulin aspart has a more rapid onset, and a shorter duration of activity than normal human insulin. [26] Insulin aspart can also be used with external insulin pumps. [13]
A diaphragm micropump uses the repeated actuation of a diaphragm to drive a fluid. The membrane is positioned above a main pump valve, which is centered between inlet and outlet microvalves. When the membrane is deflected upwards through some driving force, fluid is pulled into the inlet valve into the main pump valve.
An automatic control valve consists of three main parts in which each part exist in several types and designs: Valve actuator – which moves the valve's modulating element, such as ball or butterfly. Valve positioner – which ensures the valve has reached the desired degree of opening. This overcomes the problems of friction and wear.
A Tesla valve, called a valvular conduit by its inventor, is a fixed-geometry passive check valve. It allows a fluid to flow preferentially in one direction, without moving parts. The device is named after Nikola Tesla , who was awarded U.S. patent 1,329,559 in 1920 for its invention.
Capital parts are typically repaired or replaced during planned overhauls/scheduled inspections. As description implies, these Capital Parts are typically expensive and are depreciated over time. Examples of capital parts include pumps and motor sets used in industrial plants, or impeller or a rotor required for a pump or motor. This “spare ...
Pneumatically-actuated globe valves and diaphragm valves are widely used for control purposes in many industries, although quarter-turn types such as (modified) ball and butterfly valves are also used. Control valves can also work with hydraulic actuators (also known as hydraulic pilots). These types of valves are also known as automatic ...
A peristaltic pump, also commonly known as a roller pump, is a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained in a flexible tube fitted inside a circular pump casing. Most peristaltic pumps work through rotary motion, though linear peristaltic pumps have also been made.
A pistonless pump is a type of pump designed to move fluids without any moving parts other than three chamber valves.. The pump contains a chamber which has a valved inlet from the fluid to be pumped, a valved outlet – both of these at the bottom of the pump, and a pressurant inlet at the top of the pump.
