However, dye lasers suffer from significant disadvantages such as rapid degradation during operation, limited output power, and the need for pumping e.g. with green or blue light, making their pump sources expensive. Furthermore, dye lasers require the awkward handling of poisonous, often even ...
Under the condition of keeping other parameters unchanged, the operating conditions of the pump can be effectively adjusted by changing the number of guide vanes and wrap angle. The focus of this paper is on the presentation and demonstration of a strategy that takes the number of guide vanes ...
作者: L Juliand 摘要: Under the impetus of reducing operational cost and facing environmental regulations, ship owners are investigating the possibility of equipping 20000 GT RO-PAX ferries with a compact PUMP JET POD solution. This contribution is intended to offer ways of relaxing certain archit...
pump for the alginate feeding (syringe or peristaltic pumps) and to a gas flask (usually nitrogen) equipped with aflow meter, providing gas for theatomizationof alginate stream. Generated microdroplets are then consolidated to give themicroparticlesby agelationprocedure normally based on calcium or ...
Pump Pressure Pump pressure has a major impact on the machine’s cost. The pump pressure is very application specific. Find the appropriate water pressure requirement for your job. It will save on the initial costs and provide better cutting results. ...
