Abstract
The utility model relates to an air suction device of a water jet air ejector of a turbine, which is composed of a water chamber, a water jet pump, an air suction chamber and a condenser. A water inlet of the water jet pump is connected with the water chamber through a pipeline, a water outlet of the water jet pump is connected with a spraying nozzle in the air suction chamber through the pipeline, the pipeline connected with the lower end of the air suction chamber is communicated with the water chamber, a position of an air inlet of the air suction chamber is connected with a straight pipe which is connected with the condenser through a reversed U-shaped pipe. 1-degree gradient is formed when the straight tube is connected with the reversed U-shaped pipe, so that the air suction device solves the problem that an air suction tube of an air ejector is distributed in a U shape and liquid accumulation in the pipeline affects circulating area of air flows and cause vacuum drop, and simultaneously solves the problem that an outlet valve of a reserve pump is not closed tightly or the outlet valve is leaked, liquid accumulates in a horizontal pipe section and vacuum fluctuation of the turbine is caused during replacement of the water jet pump.
Description
Technical field
The utility model relates to a kind of air suction device, particularly a kind of steam turbine water jet air ejector air suction device.
Background technique
Water jet air ejector is the nozzle of the working water with certain pressure in hydroecium is sent into aspirating chamber of supplying with from the water-jet pump of special use, nozzle can be transformed into kinetic energy with the pressure of press water, current are to spray from nozzle at a high speed, in aspirating chamber, form high vacuum, thereby gas, the vapour mixture suction aspirating chamber of vapour condenser entered diffuser pipe.In the project organization of existing water jet air ejector, air inlet at aspirating chamber is provided with positive U type pipeline because of the installation of suction valve, go in the vapour condenser in order to prevent the working water suck-back in the nozzle, the reverse-U-shaped tube that one in device highly is not less than 10m on the pipeline of vapour condenser gas outlet is connected with U type pipe just, rises to discharge a little more than atmospheric pressure at diffuser pipe exit gas pressure at last to enter hydroecium.The water jet air ejector of this structure is in actual motion, because the positive U type of aspirating chamber air inlet place connecting tube is arranged, understand hydrops in the pipeline and influence gas flow area, and then cause vacuum to descend, simultaneously because the stand by pump outlet valve fits badly or the interior leakage of valve, horizontal pipeline section also can hydrops, often causes the steam turbine vacuum fluctuation when switching water-jet pump.
Summary of the invention
The purpose of this utility model provides a kind of steam turbine water jet air ejector air suction device, utilizes this device can not descend because of hydrops in the pipeline causes the aspirating chamber vacuum, can not cause the steam turbine fluctuations of vacuum when switching water-jet pump.
The utility model is realized in the following way: a kind of steam turbine water jet air ejector air suction device, by hydroecium, water-jet pump, aspirating chamber and vapour condenser are formed, the water intake of water-jet pump is connected with hydroecium by pipeline, water outlet is connected on the nozzle in the aspirating chamber by pipeline, the pipeline that the aspirating chamber lower end connects feeds in the hydroecium, the air inlet place of aspirating chamber connects a straight tube, straight tube is provided with air suction valve, described straight tube is connected with vapour condenser by an inverted U pipe, straight tube and aspirating chamber air inlet place connecting end are lower than and inverted U pipe connecting end, and its gradient is 1 °.
The utility model adopts said structure can thoroughly solve in the air extractor pipeline can hydrops and influence ventilation area and cause the aspirating chamber vacuum to descend, and because the stand by pump outlet valve fits badly or the interior leakage of valve, horizontal pipeline section hydrops often causes the steam turbine fluctuations of vacuum when switching water-jet pump.
Description of drawings
Fig. 1 is the structural representation of the utility model steam turbine water jet air ejector air suction device.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the water intake of water-jet pump 2 is connected with hydroecium 1 by pipeline in the steam turbine water jet air ejector air suction device, water outlet is connected on the nozzle 3 in the aspirating chamber 8 by pipeline, the diffuser pipe 9 that aspirating chamber 8 lower ends connect feeds in the hydroecium 1, the gas access of aspirating chamber 8 is connected with inverted U pipe 6 by straight tube 5, straight tube 5 is provided with air suction valve 4, and vapour condenser 7 is connected with inverted U pipe 6.
In actual motion, the working water with certain pressure that the water-jet pump 2 of special use is supplied with enters nozzle 3 through hydroecium 1, nozzle 3 can be transformed into kinetic energy with the pressure of press water, current are to spray from nozzle 3 at a high speed, in aspirating chamber 8, form high vacuum, make the gas of vapour condenser 7, the vapour mixture is inhaled into aspirating chamber 8 and enters diffuser pipe 9, connecting tube in the ingress of aspirating chamber 8 is a straight tube 5 of the present utility model, gas suction valve 4 is housed on the straight tube 5, straight tube 5 is connected with an end that highly is not less than the reverse-U-shaped tube 6 of 10m, the other end of reverse-U-shaped tube 6 is connected with vapour condenser 7, and straight tube 5 is lower than and inverted U pipe 6 connecting ends with aspirating chamber 8 air inlet place connecting ends, the air intake pipe section is provided with 1 ° the gradient, at last rises to discharge a little more than atmospheric pressure at the exit gas pressure of diffuser pipe 9 to enter hydroecium 1.
During use, because the utility model water jet air ejector air suction device adopts straight tube with the air ejector air intake pipe, air intake pipe and inverted U pipe have 1 ° the gradient when joining, in pipeline, can because of influencing ventilation area, hydrops not cause vapour gas mixing chamber vacuum to descend by pipeline, or because the stand by pump outlet valve fits badly or the interior leakage of valve, horizontal pipeline section hydrops causes the steam turbine fluctuations of vacuum when switching water-jet pump.
Claims (2)
1. steam turbine water jet air ejector air suction device, form by hydroecium, water-jet pump, aspirating chamber and vapour condenser, the water intake of water-jet pump is connected with hydroecium by pipeline, water outlet is connected on the nozzle in the aspirating chamber by pipeline, the pipeline that the aspirating chamber lower end connects feeds in the hydroecium, the air inlet place that it is characterized in that aspirating chamber connects a straight tube, and described straight tube is connected with vapour condenser by an inverted U pipe, is provided with air suction valve on described straight tube.
