进口玻璃钢潜水推流器Imported FRP submersible thruster

Product Description:

For the submersible thruster, the lifting device is fixed on the installation foundation of the pool surface, the sliding guide rail is fixed with the connecting plate and the installation foundation of the pool bottom, the cross beam of the coupling seat is fixed with the sliding guide rail, the support of the coupling seat is fixed with the cross beam of the coupling seat and the installation foundation of the pool bottom, the vertical spacing between the front coupling seat and the rear coupling seat is fixed on the cross beam of the coupling seat, the rear end of the main engine of the submersible thruster is provided with a tail wing, and the front end is provided with a lifting point, The lifting point is in front of the gravity center point of the main engine of the submersible thruster. The tail wing includes two wings. The front end between the tail wings is provided with a rail pulley and a load pulley, and the rear end between the tail wings is provided with a limit pulley. The two wings and three pulleys of the tail wing form a connecting sliding cavity. The sliding track is embedded in the sliding cavity. The tail wing and the sliding track are in the state of moving pair, the pulley and the sliding track are in the state of moving pair and rotating pair at the same time, and the tail wing, pulley and sliding track form a sliding structure It is embedded and moving.

The thruster has two states: lifting and sliding and in place operation. During sliding, the thruster is lifted by the lifting device, and the thruster slides downward along the underwater guide rail through the tail sliding mechanism, which stops when it slides to the support frame at the lower end of the guide rail. When working, the thruster is in the working state after it is in place on the underwater support frame. The submersible thruster with this structure has the following three defects: first, the tail sliding mechanism of the main engine is four groups of pulleys or front plane In the latter two groups of limit pulley types, the lifting point of the ejector is in the front and the sliding point is in the back. The lifting point and the sliding point cannot be on the same plumb line. There is friction at the sliding point, which has moderate retardation to the sliding, so the lifting point has a rotation trend and eccentric torque relative to the sliding point. In addition, the sliding mechanism at the sliding point holds the guide rail symmetrically, forming a self-locking condition, which is very easy to cause the phenomenon of sliding jamming; Second, the tail wing sliding mechanism of this structural type requires the ejector to be in an absolute horizontal state when sliding, the lifting point must be on the center of gravity of the equipment, and the sliding at the rear must not have any bump and travel resistance, which has high requirements for manufacturing accuracy and will increase the production cost. In addition, the sewage working condition is very complex, there are many uncontrollable factors, and the ideal sliding environment is difficult to control; Third, the underwater support frame is directly a simple flat plate or circular tube structure

Principle:

进口玻璃钢潜水推流器 

The coupling seat is a conical concave bracket whose notch coincides with the outward contour of the cylindrical surface diameter of the main body of the submersible thruster. The conical concave opening is upward, large at the top and small at the bottom, and the two inclined conical edges are symmetrically arranged in a shape β A circular arc is set at the bottom, and the circular arc is tangent to the conical edge. The coupling seat includes a conical concave bracket and an inner covering shock absorber. The conical notch edge and circular arc edge on the conical concave bracket are provided with a shock absorber groove embedded groove corresponding to the outer contour of the radial cylindrical surface of the submersible thruster host. The shock absorber is embedded in the shock absorber groove, and the surface of the shock absorber is m higher than the groove edge. The shock absorber and the conical concave bracket are fixed in the groove by screws
