Variable speed fluid coupling works

Liquid oil as a medium to transfer power to the working machine couplings can coordinate multi- motor drives the load distribution and transfer motor coupling constant output shaft speed can be adjusted within a certain range in the case of motor speed to achieve constant output Hydraulic pipe fittings  speed stepless adjustment, can improve the motor starting capability , reduce shock and vibration, coordinated multi-machine driven load distribution, easy to realize remote control and automatic control can save a lot of electricity. Speed ​​fluid coupling with a reasonable structure , advanced performance , high reliability , to meet the metallurgy, building materials , power generation and other industries long-term continuous operation conditions require .

Scope of application of hydraulic coupling

Hydraulic coupling range of applications , what is it ? Following is a brief introduction for everyone .1 , laborers machinery, ceramic machinery, construction machinery .Hydraulic tube fittings2 , scraper conveyor, belt conveyor .3 , mining machinery, metallurgical machinery, cranes.4 , pumps, boiler feed pumps, circulating pumps, condensate pumps , the original pump, pump, mud pump, slurry pump , sand pump .5 , blower , exhaust fan converter , electric furnace dust blower , blast furnace dust blower , blast furnace blowers, induced draft fan , blower .6 , centrifuges, mixers , belt conveyors .

Composition of fluid coupling

Main components : the pump wheel , turbine , turning housing , an input shaft , an output shaft and a spoon pipe . Normally, turning the shell and the pump wheel rim flange is bolted connection.Pump wheel and turbine called the working wheel, two in both blades, two to input , output shaft connection, there is a gap between them , the radial impeller and turbine are the same size as the cavity shape, so , together form the working Hydraulic pipe fittings , the working oil from the pump into the inside wheel and rotates together with the following power machine , the oil in the centrifugal force , left to the outside of the pump wheel , the formation of high-speed turbine oil flow toward the opposite leaves , gradually slow down the flow of the turbine inner flow back into the pump wheel and the inside , forming a circulation of oil . The working fluid in the working chamber the absolute flow is a three-dimensional motion . Turn the pump wheel casing surrounds the turbine after connection , the energy stored in the working fluid into the pump wheel . Associated with the input shaft power machine ( such as motors ) , the output shaft and the driven machine associated ( such as pumps ) .

hydraulic coupling failure analysis

Hydraulic coupling PTO shaft itself is cantilevered and radial thrust bearing , this support structure in the installation , the response bearing clearance and bevel gear gap to be adjusted to ensure correct meshing . Bearing wear , it must be timely adjustment and replacement.Hydraulic pipe fittings , once the gap becomes large , so damage to the normal meshing bevel gears , causing additional load , resulting in deterioration of working conditions bearings , gear teeth , the bend axis limp . If you belong to the working machine load sudden overload situation , you can install the output shaft torque limiter or safety couplings. Conveyor shaft bevel gear reducer and hydraulic coupler is fitted together , the structure is irrational, weight, and easy installation and removal process caused by the collision axis bending deformation ; factory fluid coupling is for only for static balance test , at high speed , because the added unbalanced loads and shaft vibration , deterioration of the operating state of the shaft .

the fluid coupling fusible plug causes damage to the seven

Fusible plug fluid coupling causes of damage are the following , we look together .1, the filled amount is too small , the required oil-filled .2, the coupling leak, check for leaks combination of surface and shaft , replace the seal .3 , overload occurs , check Hydraulic ferrules consumption , eliminate the overload .4 , the phenomenon of the working machine with a brake , maintenance work machine , remove the brake failure.5 , frequent start , not too frequent starts.6, the start-up time is too long , check the power consumption.7, the coupling size is too small , the replacement of a suitable coupling .
