A high-pressure and low-pressure selecting valve includes a valve body and a valve member movably provided in the valve body. The valve body has a pair of input ports, at least one output port, and a low-pressure port. The input ports, the output port, and the low-pressure port are...
The press cushion, for high and low pressure presses, is free of asbestos and is woven from one of two materials from an initial gp. with one or more materials from a second gp. except when the second gp. material is a yarn from a first gp. material without metal threads. The first...
high- pressure and low-pressure air supply systems. For each air supply configuration, air mass flow and pressure operating conditions can be found that result in an equal value of the oxygen partial pressure at the cathode catalyst layer surface. However, at the system level, the required air...
High and low pressure pumping systems for cryogenic or liquefied gasesHigh and low pressure pumping systems for cryogenic or liquefied gases comprise at least one cryogenic tank (1) in which the liquefied cryogenic gas is stored at low pressure and at least one vaporizer (2) which is connected...
The meaning of HIGH-PRESSURE is having or involving a high or comparatively high pressure especially greatly exceeding that of the atmosphere. How to use high-pressure in a sentence.
然后,在一个整天工作以后,回去在家到北京和吃晚餐那里。[translate] aHigh and low pressure pressure low 高和低压压力低[translate]
In oil & gas industrial plants, High Integrity Pressure Protection Systems (HIPPS) are widely used as barrier between high pressure and low pressure sections. Hence, it is necessary to optimize its reliability, availability and, maintainability to help in the implementation of HIPPS maintenance planni...
Furthermore, the polycrystalline GaAs has a lower content of impurities (e.g., C and Si) than low-pressure synthesis material and a defined As/Ga ratio, so GaAs with an As excess can be synthesized. The boron oxide contributes to further purification of the melt, and the general impurity...
This paper reviews the low-pressure (<10 Pa). high-density plasma-assisted nitriding processes recently developed for metallurgical surface modification to improve wear, hardness and fatigue resistance of ferrous and non-ferrous materials. For that purpose, plasma generation is most frequently ensured ...
In known compressed air systems of this kind, the low pressure part is supplied via a pressure relief valve arrangement. Known pressure relief valve arrangements close gradually as the pressure in the low pressure part approaches the value of the low pressure and thereby cause repeated switching on...
