Abstract
The utility model discloses a kind of gas compressor anti-surge anti-plugging flow control device.It comprises pressure shell, has impeller in pressure shell, and pressure shell has intake grill, and the center line of described intake grill overlaps with the longitudinal center line of impeller.Pressure shell edge surrounding has air channel, and described air channel is communicated with intake grill.The pressure shell being characterized in intake grill surrounding has circular groove, the bottom land of circular groove has gas regulation hole, this gas regulation hole be connected with the passage between intake grill with air channel and with the blade of turbine in the middle of corresponding.Adopt this mechanism, the generation of compressor surge and blocking phenomenon can be avoided, be conducive to the operation of pressurized machine and the prolongation in working life.Can be used to blocking phenomenon when surge when eliminating the gas compressor small flow of automobile booster and large discharge.
Description
Technical field
The utility model relates to a kind of compressor casing.Specifically, the flow control device of blocking phenomenon when being used to surge when eliminating the gas compressor small flow of automobile booster and large discharge.
Background technique
All know at pressurized machine production industry, when vehicle traveling process slows down, due to the unexpected minimizing of the gas flow of impeller inlet, pressurized machine there will be violent surge.And when the gas flow of impeller inlet is larger, there will be again flow blocking phenomenon.No matter be that surging phenomenon occurs, or blocking phenomenon, all can bring adverse effect to the operation of pressurized machine and working life.
Model utility content
Problem to be solved in the utility model is to provide a kind of gas compressor anti-surge anti-plugging flow control device.Adopt this mechanism, the generation of compressor surge and blocking phenomenon can be avoided, be conducive to the operation of pressurized machine and the prolongation in working life.
The problems referred to above to be solved in the utility model are realized by following technological scheme:
Gas compressor anti-surge anti-plugging flow control device of the present utility model comprises pressure shell, and have impeller in pressure shell, pressure shell has intake grill, the center line of described intake grill overlaps with the longitudinal center line of impeller.Pressure shell edge surrounding has air channel, and described air channel is communicated with intake grill.The pressure shell being characterized in intake grill surrounding has circular groove, the bottom land of circular groove has gas regulation hole, this gas regulation hole be connected with the passage between intake grill with air channel and with the blade of turbine in the middle of corresponding.
Take such scheme, have the following advantages:
As can be seen from the above scheme, the pressure shell due to intake grill surrounding has circular groove, the bottom land of circular groove has gas regulation hole, this gas regulation hole be connected with the passage between intake grill with air channel and with the blade of turbine in the middle of corresponding.When intake grill gas flow reduces suddenly, by the gas regulation hole on circular groove bottom land, can supplement gas flow, avoid the generation of surge condition.When there is gas flow increase, flow blocking phenomenon, by the gas regulation hole on circular groove bottom land, can drain gas flow in runner, the flow in runner is regulated.Generally speaking, by the gas regulation hole on circular groove bottom land, can regulate gas flow, thus avoid the generation of surge and blocking phenomenon, not only ensure the normal operation of pressurized machine, also can extend the working life of pressurized machine.
Accompanying drawing explanation
Fig. 1 is gas compressor anti-surge anti-plugging flow control device schematic diagram of the present utility model, and this figure is that the gas of gas flow when reducing suddenly moves towards schematic diagram;
When Fig. 2 is gas flow increase, flow blocking phenomenon, the gas of gas compressor anti-surge anti-plugging flow control device moves towards schematic diagram.
Embodiment
As depicted in figs. 1 and 2, gas compressor anti-surge anti-plugging flow control device of the present utility model comprises pressure shell 3, and be provided with impeller 5 in pressure shell 3, pressure shell 3 be processed with intake grill 1, the center line of described intake grill 1 overlaps with the longitudinal center line of impeller 5.Pressure shell 3 edge surrounding is processed with air channel 4, and described air channel 4 is communicated with intake grill 1.The pressure shell 3 of intake grill 1 surrounding is processed with circular groove 2, the bottom land of circular groove 2 is processed with gas regulation hole 6, this gas regulation hole be connected with the passage between intake grill 1 with air channel 4 and with the blade of turbine 5 in the middle of corresponding.
See figure, 1, when the gas flow of intake grill 1 reduces suddenly, by the gas regulation hole 6 on circular groove 2 bottom land, can supplement gas flow, avoid the generation of surge condition.See Fig. 2, when there is gas flow increase, flow blocking phenomenon, by the gas regulation hole 6 on circular groove 2 bottom land, can drain gas flow in runner, the flow in runner is regulated.Generally speaking, by the gas regulation hole 6 on circular groove 2 bottom land, can regulate gas flow, thus avoid the generation of surge and blocking phenomenon.
