Description
Technical field
The utility model relates to a kind of vaccum-pumping equipment, particularly a kind of water jet air ejector.
Background technique
The characteristic parameter of weighing water jet air ejector throughput is the volume mass ratio of induced-to-inducing air, desires to make air ejector to reach high efficiency, must make mass ratio of induced-to-inducing air reach maximization.Because working water is water, vapour milkiness shape liquid with being sucked after gas mixes, to flow and the correlation between severe of this working medium can't set up accurately mathematic(al) representation at present, thereby the designing and calculating of water jet air ejector still belongs to empirical design.For the water jet air ejector under a kind of given operating conditions, data according to experiment and summary of experience, just can determine geometrical construction, nozzle shape size, trunnion shape and length, larynx footpath, nozzle area ratio and the bulk range etc. of its suction chamber, such water jet air ejector is in newly built construction or extension project, and performance can both reach designing requirement basically.But some has occurred and depart from the situation of former design condition in engineering practice, making some water jet air ejector reach the user place in factory is qualified after testing, but is applied to can't meet the demands in the technology innovation project.
Through a large amount of user's field investigation and the experiment of factory, the reason that discovery can't meet the demands has two: the first, water-jet pump is former unit pump, the user directly adopts old pump for reducing cost, and the former design of water-jet pump and air ejector has just caused with pump and do not matched like this; The second, the bearing of water jet air ejector is existing with former unit, is similarly to reduce cost, and air ejector setting height(from bottom) and former different design will appear in compression retrofit work amount, make that the working water loss of head is bigger.Contrast is found by experiment, other condition is all constant, change water bundle bulk range in the air ejector suction chamber, make that originally underproof air ejector but can engineering demands, this is because the interior nozzle of the water jet air ejector body of certain typing, trunnion and bulk range are fixed, they are by the water-jet pump of determining, the height that jetting pipeline and permission are installed etc. determines, but when above condition changes, the water harness shape of nozzle, the water bundle be sucked the gas area of contact and all change, the water bundle sweeps along the ability of gas also to weaken thereupon, cause fluid in trunnion contraction section undercompounding, and be detained in the trunnion ingress, backflow etc.; And bulk range is in suitable scope the time, the formed fluid of water bundle just can reach best working state, this just shows under this kind condition, the ability to work of water jet air ejector mainly is to be determined by bulk range, in order to satisfy the actual demand of user engineering, must make water jet air ejector have very strong versatility, to satisfy the requirement that under multiple condition, all can be suitable for.
