Available as either a mechanically sealed or magnetically driven unit, the side channel pump can be configured to your individual requirements with a variety of material options. Side channel pumps are capable of handling gas en trained liquids with up to 50% inclusion with a temperature range of -20°c → +120°c as standard; with modifications capable of increasing the range significantly.
17/5/2019 · In the past years, many attempts have been made in order to model the process of bone remodeling. This process is complex, as it is governed by not yet completely understood biomechanical coupled phenomena. It is well known that bone tissue is able to self-adapt to different environmental demands of both mechanical and biological origin. The mechanical aspects are related to the …
A self-propelled concrete cutting saw in which the saw and self-propelled platform associated with the saw are both driven by hydraulic motors, with separate motors for each of the two propelling wheels so that the device may be steered by varying the speed of
This design consists of a square, concrete pump base whose design is dependent on bearing weight and site soil characteristics. Where freezing conditions require the use of a pitless adapter, and the well casing and annular seal do not extend above ground surface or into a pit or vault, a concrete base or pad shall be constructed as a permanent location monument for the covered well.
Fig. 73 Self-priming centrifugal pump 3.8.9 Self-Priming Jet Pumps An alternative type of self-priming centrifugal pump uses the fact that if water is speeded up through a jet, it causes a drop in pressure (see Section 3.8.2). Here the pump is fitted into aFig. 74).
Wheels or groups of wheels can be mechanically coupled and driven by a common pump. In this case, standard motors instead of wheel motors must be used. Roller chain is often a convenient way of coupling two or more wheels on the same side of the vehicle if …

Mechanical ventilation, assisted ventilation or intermittent mandatory ventilation (IMV), is the medical term for artificial ventilation where mechanical means are used to assist or replace spontaneous breathing. This may involve a machine called a ventilator, or the breathing may be assisted manually by a suitably qualified professional, such as an anesthesiologist, Registered Nurse
The inner piston is mechanically driven by an engine associated reciprocating drive and pumping action occurs as a result of the spring operating on the inner piston. The position of the outer piston relative to the inner piston is determined by the pressure in the pumping chamber as regulated by the force of the spring operating against the outer piston.
28/9/2014 · A relatively simple self regulated glucose responsive monolithic system for episodic insulin delivery was studied by Brown et al., . Two elements were involved in the system's response to glucose. First, glucose oxidase, in conjunction with gluconolactonase and catalase, was used to convert glucose to hydrogen ion (H + ), leading to a drop in pH inside the pores of the monolith.
A pump unit comprising co-operating, push-pull connected reciprocating pumps for the pumping in portions of contents to packing containers on a packing machine. The reciprocating pumps (1) each comprise a control piston (4) connected to the pump piston (6) in
1 Chapter 7 MECHANICAL VENTILATION AND SMOKE CONTROL SYSTEMS 7.1.1 General (a) Where air-conditioning system is provided in lieu of mechanical ventilation system during emergency, all the requirements specified in this Code for the mechanical
The priming unit 10 of the self-priming pump system 8 includes a priming column 45 divided into a well chamber 46 and a vacuum chamber 48. The well chamber 46 is coupled to the off-set T-fitting and includes a plate deflector 47 to direct the dynamic flow of intake liquid into the inlet 30 of the primary pump …

A condensing steam locomotive is a type of locomotive designed to recover exhaust steam, either in order to improve range between taking on boiler water, or to reduce emission of steam inside enclosed spaces. The apparatus takes the exhaust steam that would normally be used to produce a draft for the firebox, and routes it through a heat
