Normal circumstance of diaphragm coupling applied to variable frequency velocity control tools
JMB variety coupling is utilized to HangZhou Oilfield Thermal Power Plant
According to the specifications of HangZhou Electric Energy Company, HangZhou Oilfield Thermal Energy Plant must dynamically alter the power era according to the load of the power grid and market demand, and carry out the transformation of the frequency converter and the suction admirer. The motor was at first a 1600KW, 730RPM non-frequency variable speed motor matched by HangZhou Motor Factory. The pace manage manner after changing the frequency is guide handle. Press the button speed to enhance 10RPM or drop 10RPM. The coupling is nonetheless the first elastic decoupling coupling, and the elastic de-coupling coupling right after frequency conversion is often ruined, which right affects the regular electrical power technology.
It is located by way of analysis that in the method of frequency conversion velocity regulation, the pin of the coupling can not bear the inertia of the velocity regulation method (the diameter of the fan impeller is 3.3 meters) and is minimize off, which has wonderful damage to the motor and the fan.
Later on, they switched to the JMB460 double-diaphragm wheel-sort coupling of our manufacturing facility (patent quantity: ZL.99246247.9). Following 1 hour of damaging expCZPT and far more than a single yr of procedure take a look at, the gear is managing extremely properly, and there is no Replace the diaphragm. twelve models have been rebuilt and the procedure is in excellent condition.

Set or Class 1 pulleys have a mounted shaft. That is, the shaft is “fastened” or anchored in location. A fixed pulley is a force employed to modify the path of the rope (called a belt simply because it tends to make one change). Fixed pulleys have mechanical advantages of mounted pulleys. Active pulleys or 2-phase pulleys have free of charge shafts. That is, the axis can transfer “freely” in space. Relocating pulleys are utilized to change forces. Energetic pulleys have the mechanical advantage of two pulleys. That is, if one conclude of the rope is stationary, pulling the other stop of the rope will exert two times the pressure on the object attached to the pulley. A composite pulley block is a blend of a fixed pulley block and a movable pulley block. Blocks – Blocks are composite pulleys in which multiple pulleys are mounted on every axle, more including to the mechanical benefit. Pulleys can modify the route of the power.
