Application Of Laminar Jet
- Jun 13, 2017 -

    A fluid element consisting of a jet as a working medium and consisting of a fluid flow mechanism. A jet is a stream of air or liquid that is ejected from the nozzle.

    The laminar flow is divided into pneumatic laminar flow and hydraulic laminar flow by working medium. According to the fluid flow mechanism, laminar flow is divided into three types: turbulent, wall and momentum.

① turbulent laminar flow: the use of laminar flow of the main jet in the interference under the action of air flow from laminar flow into turbulent flow of the principle of the principle, it is essentially a multi-input "or non-laminar flow jet."

② wall-mounted laminar flow jet: the use of the main jet in a specific shape of the chamber due to the role of fluid suction caused by the wall effect produced by the common bistable components, or non-components, counting trigger components. ③ momentum laminar flow: the use of two streams in the role of the chamber for the exchange of momentum made by the principle of common with the door components, half-price components, such as proportional components.

    The laminar flow must be combined with other devices to control the parameters to be controlled automatically. The figure shows the laminar flow for liquid level control. When the liquid level h is zero, turn off the manual valve, or non-laminar flow control tube is not flooded by the liquid. The jet is output at the J1 terminal and the membrane is opened by the amplifier. The liquid begins to feed the container.Laminar Jet

   When the liquid level reaches the required height, the control tube is submerged, or the non-component is switched, the jet is output from the J2 side, and the indicator light is illuminated by the gas-electric conversion element, indicating that the liquid level is required. At this point, due to the disappearance of J1, membrane control valve closed, you can open the manual valve, the system into the automatic control phase.Laminar Jet

   When the liquid level due to the output of the flow down, the control tube open, J1 output to open the valve; when the level reaches the required height, the valve is closed, in order to achieve automatic liquid level control. The laminar flow has the advantages of corrosion resistance and explosion protection. Therefore, it is safe, reliable and economical to use the jet control system for the process of chemical liquid and gas which may cause combustion, explosion and poison. The jet technology can show its superiority when it is required that the automatic control device be able to operate reliably under extreme conditions such as strong vibration, strong irradiation, high temperature, etc. However, the jet signal transmission speed is slow, and the transmission process signal waveform is easy to deformation, it should not be used to form a very complex control system. Laminar flow energy is far less than the power is not easy to get, and whether or not the work of continuous consumption of energy, so the efficiency is low. These drawbacks limit the application of laminar flow.Laminar Jet
