Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further details:
As shown in Figure 1, the utility model comprises pressurizer tank 2, be installed on air inlet pipe 4 on pressurizer tank 2, escape pipe 5, detect pressure sensor 6 and the Pressure gauge 1 of voltage stabilizing loading pressure, be installed on the air inflow adjusting device in air inlet pipe, control the controller of air inflow adjusting device. Described air inlet pipe 4, escape pipe 5 are communicated with pressurizer tank 2 inner chambers, escape pipe 5 connecting engine air inlet pipe, for avoiding the admission pressure fluctuation that air throttle when work brings directly to enter engine, described air inlet pipe is installed on a side of pressurizer tank, escape pipe is installed on the opposite side of pressurizer tank, and escape pipe in the position of opposite side and air inlet pipe in the setting of staggering of the correspondence position of opposite side; Best set-up mode is: air inlet pipe is installed on the bottom of pressurizer tank one side, and escape pipe is installed on the top of pressurizer tank opposite side. Described pressure sensor 6 is wired to controller.
During for fear of engine operation, pressurizer tank 2 internal pressure ripples, in the reflection of pressurizer tank inwall, cause vibration, on described pressurizer tank inwall, porous acoustical panel 7 are installed.
In order accurately to detect the admission pressure of engine that pressurizer tank offers, avoid being subject to the impact of air-flow as far as possible, described pressure sensor and Pressure gauge are all installed on the side near escape pipe on pressurizer tank. Pressure gauge is for demonstration directly perceived, and precision is lower, and pressure sensor is for controlling, and precision is higher.
For the ease of controlling, air inflow adjusting device of the present utility model adopts air throttle, and the device that certainly can carry out Flow-rate adjustment is a lot, such as: flow control valves etc., adopting air throttle is to consider that air throttle is familiar in industry, simultaneously convenient buying.
The function of controller of the present utility model is: the pressurizer tank gas outlet place's pressure detecting according to pressure sensor 6 and the pressure of setting are adjusted the aperture of air inflow adjusting device (air throttle), thereby controls the plateau pressure of pressurizer tank simulation. For convenience of using, pressure control function switch is set, for the opening and closing of pressure control function on controller. In the time that function is closed, air throttle is in normal open state, and pressurizer tank internal gas pressure equals environment atmospheric pressure. Pressure control is set and sets button or set potentiometer, for setting pressurizer tank internal pressure control desired value. Meanwhile, malfunction indicator lamp can also be set, when control system detects fault, cannot normally work time, show malfunction and fault message by malfunction indicator lamp.
Pressurizer tank of the present utility model is the critical piece of whole system, and its volume is large, cross section large, length is shorter, and its effect is that logical excess volume reduces air throttle and air input of engine by air changes the admission pressure fluctuation causing. And by the air inlet pipe and the escape pipe that are staggeredly arranged, the admission pressure fluctuation bringing while avoiding air throttle work directly enters engine.
Air throttle is pressure regulating part of the present utility model. In the time that engine intake airflow increase causes pressurizer tank internal pressure to decline, throttle opening increases, and the speed in ambient air stream cartonning increases, and makes pressurizer tank internal pressure keep constant; When otherwise engine intake airflow reduces, throttle opening reduces.
Air inlet pressure sensor offers the admission pressure of engine for detection of pressurizer tank. For controller provides pressure signal.
Principle explanation: after controller powers on, whether detected pressures gauge tap is opened, if pressure control function is opened, the pressurizer tank internal pressure control desired value providing according to admission pressure control setting device, and the case internal pressure that provides of air inlet pressure sensor, adjust throttle opening, make pressurizer tank internal pressure remain on pressure control desired value.
