Definitions

  • the actuation of the injector is carried out by a simple opening of the valve 60. Once this open valve, the steam pushes the water contained in the 61 through the inlet 40 of the injector, and by the pipe 62 and the tank 63. The steam plays the role of a piston on the water contained in the reservoir 63. A steam-water interface 76 is established in the reservoir 63. The water thus driven out of the injector by the exit 42 and is sent gradually into the balloon 48 by compressing the inert gas contained in this balloon. The flush of water from the reservoir 63 is done through the ejector C, then the pipe 70, and therefore by the source of the steam injector. This flush can not be done by the return loop R, because of the flap 46.
  • valve 43 When the pressure at the exit 42 becomes greater than the pressure of the steam generator G, the valve 43 opens, allowing its water supply. At the same time as the valve 43 opens, the valve 46 also opens under the effects of pressure. The pressure at the inlet of the ejector increases slightly and becomes larger than that of the tank 63 which is always at the pressure of the steam. As a result valve 65 closes. The ejector continues to work by sucking the water from the tank 73. The driving fluid of the ejector is no longer the water of the capacity pushed by the steam but some of the water coming out of the injector. At this moment the injector reaches his diet permanent.
  • the interest of placing the injector and its ejector in a swimming pool can represent a gain in size: when placed in the bottom of the pool, the pressure at the source is increased from the static pressure due to the water level above these components.
  • a condition of good functioning of the steam injector, in particular with regard to the pressure gain, is the temperature of the source that must be as cold as possible. But the loop of return R between output 42 and the ejector brings hot water. It is cooled to the level of the ejector by mixing with the cold water of the pool that is sucked to the ejector. In case he would be necessary to obtain a high pressure gain at level of the output 42 of the injector it is possible to cool the source of the injector, cooling the water circulating in the return loop R.
  • This pressure downstream of the valve 100 is equal to the vapor pressure via cylinder 102 minus the pressure losses in the pipe 104. These losses of charge will have to be adjusted according to the conditions required by having a throttling 110 downstream of the cylinder 102, for example at the inlet of the pipe 104.
  • the flapper opens, the ejector goes into action in driving low pressure water from the pool 90 via its entrance 107.
  • the source 41 of the cylinder at the ejector the source is fed by the cylinder and the ejector, as long as the piston 103, pushed by the steam, does not abut on the downstream outlet of the cylinder. Once this phase is over, the food in spring water comes only from the outlet of the ejector at an intermediate pressure between pressure of the steam and pressure of the pool 90.
