Pressure damages equipment, and it is even more steam turbine red switch essential condition that condenser, which establishes vacuum,.Condenser and some low-voltage equipments
(such as condensate pump, condensing pump and part low-pressure heater) when operating normally, inside is in vacuum state, due to pipeline and
Shell imprecision, air will be leak into, to destroy condenser vacuum, jeopardize the safe and economic operation of steam turbine.Meanwhile air
Partial pressure in condenser increases, and the dissolved oxygen amount of condensed water is caused to increase, thus corrosion of the aggravation to heat power equipment and pipeline,
Moreover, the presence of air also increases the heat transfer resistance in condenser, cooling of the recirculated cooling water to turbine discharge is influenced, is increased
Plant consumption.Therefore, when condenser is run, it is necessary to constantly extract air therein out.Existing condenser, which vacuumizes, to be set
Standby mainly to have air ejector and vacuum pump, air ejector is widely used in domestic large and medium-sized machine because its system is simple, reliable operation
In group.
Existing water jet air ejector is usually made of intake chamber, (operating) water nozzle, suction chamber, non-return valve, trunnion, and existing water
Nozzle mainly by constituting in horn-like outer tube, has only been penetrated a jet hole, can only have been sprayed by one in course of injection on outer tube
Out, so that steam-water mixing is uneven.Disclosing one kind in the prior art, application No. is 201020286298.4, entitled jetting pumpings
The utility model patent of gas device is equipped with loudspeaker Jet flow distribution filter screen in the patent, can make to enter the indoor water of vacuum in this way
It is evenly distributed, meanwhile, if steam flow distribution plate, keep the indoor steam-water mixing of vacuum uniform, but loudspeaker Jet flow distribution filter screen
All the vapour gas in air chamber can be caused to stop with steam flow distribution plate, cause intake velocity slow, pumping efficiency is low, and structure is multiple
It is miscellaneous, higher cost.
