We have already described the selection of racks and reducers in domestic reference books, but these methods are only qualitative descriptions, and there is no quantitative calculation. The foreign reference books and published documents are clearly described in the calculation method. The selection of the reducer and the frame depends on the force. These forces are derived from the force exerted by the fluid on the agitator. These forces are finally transmitted to the frame or decelerated. On board, it is supported by bearings. Below we will see how the rack and reducer should be selected according to the force of the agitator. When the agitator shaft rotates, the fluid motion generates various moments and forces, of which the important moments are bending moment, torque and axial thrust. The forces and moments acting on the agitator are shown in the figure. Force and moment acting on the agitator *Part: Calculation of bearing force When the agitator shaft is twisted, the force of the fluid causes the agitator shaft to generate a bending moment. The main components of the axial thrust are ( 1 ) the weight of the agitator shaft and the agitator; ( 2 ) the upward thrust acting on the shaft section due to the pressure difference between the inside and outside of the equipment; ( 3 ) the agitator generating the axial reverse flow of the fluid. In the cantilever section, the bending moments on the agitator shaft at a distance of x from the agitator are: A —— agitator shaft area at the seal, m 2 It can be seen from the formula that the core of the bearing force depends on the radial force of the fluid that the agitator is subjected to. In the next section, we will continue to introduce the fluid radial force of the agitator. Bump keys are specially designed with a specific cutting technique that can sidestep the security mechanism in the average tumbler and pin lock. Bump keys are designed to exploit a loophole that`s built into most pin and tumbler locks. You see, the pin stacks in a pin and tumbler lock are spring loaded to keep the cylinder in place so that it can only be turned with the right key.
