The frequency converter is relatively expensive and requires installation. It is also inconvenient, and the energy consumption is relatively high, which cannot meet the requirements of high-efficiency supercharging, cost reduction and energy saving.

Detailed ways

The specific embodiment of the present utility model is described in conjunction with accompanying drawing:

As shown in accompanying drawing 1, the transmission part of the supercharging component is installed on the shaft 4 inside the air duct, and a hydraulic motor is used as the power system, and the hydraulic motor 5 and the supercharging impeller group 1 adopt the coaxial 4 installation method.

As shown in Figure 2, the impeller is made of a super-strength composite alloy after forging and finishing. The fan surface 3a of the blade is designed to have a certain rotation arc α with thin wings and a thick middle; α is designed to be 86°, and the fan surface 3a of the blade The front radian is larger than the back radian.

As shown in accompanying drawing 3 and accompanying drawing 5, the described hub is composed of a detachable left sub-wheel base 2a and a right sub-wheel base 2b, and the petioles 2c of several blades 3 are snapped on the left wheel base 2a in sequence at a certain angle. On the clamping block 2c, the leaf ball 3c at the bottom of the impeller is just fixed by the clamping block 2c. After installing all the blades 3 to be installed on the hub 2a at a certain angle in sequence, the left wheel seat 2a and the right wheel are made 2b Fasten with bolts.

As shown in accompanying drawing 1, the size of each impeller of each set of supercharging impeller group 1 can be the same or different. Connect with the shaft 4 and put it into the air cylinder 6.

The working principle is shown in FIG. 1 , two sets of booster impellers 1 are installed on the shaft 4 , and the hydraulic motor 5 is installed on the rear of the shaft 4 . When the equipment is started, the impeller in the booster impeller set rotates at a high speed driven by the hydraulic motor, and the gas enters from the air inlet of the fan cylinder 6. After passing through the impeller of the first booster impeller set, the gas is accelerated instantly by the drive of the impeller. Movement and extrusion, the flow speed increases, the air pressure increases, and the first pressurized airflow passes through the second pressurized impeller set to be pressurized again, and the airflow is in the two sets of pressurized impeller sets. The fan surface 3a is made of super-strength composite alloy after forging and finishing, and the blade fan surface 3a is designed to have thin wings, thick middle and a certain rotation arc α, 84°≤α<90°, the blade fan The front radian of the wind surface 3a is greater than the back radian of the blade fan face 3a, and the front surface area of the blade fan face 3a is smaller than the back surface area of the blade fan face 3a. At this time, the wind speed through the back radian is faster than the front radian, thereby generating a backward thrust. At the same time, there is a rotation arc α between the fan surfaces 3a of the blades; thus, an inward thrust is generated when the fan surfaces 3a of the blades rotate, and the two forces of the inward thrust and the backward thrust are superimposed on each other, finally making the wind speed faster and faster. The flow velocity increases and the air pressure increases. After two groups of pressurization, the wind pressure, wind speed and air pressure in the air cylinder 6 can be increased to the design value.

The rotation speed of the impeller of the utility model reaches a high speed above 4000/s. Since the air outlet of the air cylinder 6 is equipped with a water mist nozzle, the airflow ejected at a high speed from the air outlet of the air cylinder 6 carries the water droplets of the water mist nozzle to spray together. It can spray to a distance of 100-200 meters.

In the booster impeller set of the present utility model, the gap between the end of the blade and the inner wall of the air cylinder 6 is in the range of 1-2 millimeters, which can enhance the supercharging effect of the booster impeller set. The transmission part of the utility model adopts a hydraulic motor as a power system, and the hydraulic motor can provide a high speed of more than 4000/s.

The connecting ends of the blade fan surface 3a and the hub 2 in the impeller are installed at the same angle. Further, during installation, several impellers 1 in the two sets of booster impellers are rigidly connected and installed in the same direction of rotation, so that the two sets of booster The supercharging direction of the impeller group can produce thrust from front to back, thereby producing technical effects superimposed on each other.
