Software Scenario

Typical scenario of diaphragm coupling utilized to variable frequency speed control tools

JMB kind coupling is used to HangZhou Oilfield Thermal Electrical power Plant

According to the requirements of HangZhou Electric powered Power Company, HangZhou Oilfield Thermal Electrical power Plant should dynamically adjust the electricity generation according to the load of the electrical power grid and market demand from customers, and have out the transformation of the frequency converter and the suction fan. The motor was at first a 1600KW, 730RPM non-frequency variable velocity motor matched by HangZhou Motor Manufacturing unit. The pace manage method following shifting the frequency is manual control. Press the button speed to improve 10RPM or fall 10RPM. The coupling is nevertheless the unique elastic decoupling coupling, and the elastic de-coupling coupling soon after frequency conversion is usually damaged, which straight affects the typical power technology.

It is discovered through investigation that in the approach of frequency conversion speed regulation, the pin of the coupling can not bear the inertia of the pace regulation procedure (the diameter of the admirer impeller is 3.3 meters) and is minimize off, which has great hurt to the motor and the enthusiast.

Afterwards, they switched to the JMB460 double-diaphragm wheel-kind coupling of our manufacturing unit (patent amount: ZL.99246247.9). Right after 1 hour of damaging expCZPT and far more than a single yr of procedure examination, the tools is working quite properly, and there is no Substitute the diaphragm. 12 units have been rebuilt and the operation is in excellent issue.

Consisting of two radially slotted hubs and a serpentine spring metal band, the mesh coupling provides the torsional damping and adaptability of an elastomer, but with the strength of steel. Grid couplings transmit torque and modify angular, parallel and axial misalignment from a single hub to one more by oscillating and sliding a tapered grid in the hub grooves. The mesh cross section is generally tapered for far better hub make contact with and less difficult assembly. Lubrication is necessary because of to the movement in between the contact hub and the mesh steel components.
