Buck Hydraulic Coupler In The Motor Start

Frist´╝îRotary valve closes when motor speed out of range. Later, under the action of centrifugal force turn valve closed, the working chamber and auxiliary rooms after the channel is betting, the working fluid stop auxiliary cavity flows backward.

Startup characteristics of stationary motor and coupler, machine still, coupling auxiliary cavity with cavity oil well after flat cavity washed fluid decreases, creating the conditions for reducing the starting torque.

Two, start, Buck started the motor, coupling valve opens motor low voltage start, due to the fluid coupling liquid in the cavity for large circulation of movement, flow under pressure in a ring, after further into the liquid through the valve and auxiliary cavity, coupling the starting torque decreases. Motor starts smoothly because of low load torque, rapid coupling the pump up to rated speed, starting current is greatly reduced.

Three, start the motor stationary motor with coupling, machine still, coupling auxiliary cavity with cavity oil well after flat cavity washed fluid decreases, creating the conditions for reducing the starting torque.

Four, Yan Chong, coupling compartment began supporting the working liquid in the cavity orifice is slow (latency) flows into the working cavity, cavities flush liquid increases, the transmitted torque increases.

Conveyor starting five: when a coupling torque torque greater than conveyor after, conveyor starts.

Converting five, motor rated voltage motor is complete, converted to its rated voltage.

Six, coupling delay start conveyor: rush liquid coupled cavity increases, torque increase, conveyors with a coupling torque increases and slow start.

Seven, motor and coupling rated working conditions (conveyor running at full speed) performance of normal Coupler, obviously, if not long after the auxiliary chamber valve-controlled coupling, the coordination of such a curve is not motor starts at low voltage conditions.

Eight, coupling delay start conveyor: rush liquid coupled cavity increases, torque increase, conveyors with a coupling torque increases and slow start.
