How To Operate The Directional Coupler Safely
Jun 22, 2017

How to operate the Directional Coupler safely
Directional Coupler only safe to use, in order to ensure the normal use of the machine, the following details on how the Directional Coupler to run safely:
1, Directional Coupler must use flame retardant liquid as the working medium.
2, pump wheel, turbine wheel and the shell should be prevented from deformation, damage, corrosion or cracks. The shell has a slight crack, can be welded to repair, but should eliminate the internal stress.
3, the repair should be static pressure test, filling the pressure of 0.3MPa, the hydraulic coupling inflatable mouth sealed, to maintain 5min, the pressure shall not decline.
4, a centrifugal rotary valve hydraulic coupling, centrifugal valve must be added to the action of the action, the action should be flexible and reliable.
5, the hydraulic coupling should be done after the static balance test, the center of gravity on the rotation of the axis of the deviation of not more than 0.02mm.
6, fusible alloy plug must be complete, the melting temperature should be consistent with the provisions of the type of hydraulic coupling.
Tips: safe use of Directional Coupler, contribute to the normal work, the safety of workers is also a responsibility, but also to extend the life of the machine.
  The range of Directional Couplers is very wide. Different work machines have specific requirements for Directional Couplers. Only the choice of Directional Coupler in line with the requirements of the work machine in order to ensure the good operation of the machine.
    Such as belt conveyors in order to ensure that the conveyor belt will not be damaged when the start, so the matching Directional Coupler required to start the characteristics of soft. The power plant boiler air preheater requires the Directional Coupler to start the characteristics of hard, which is to ensure the smooth start. Thus, the Directional Coupler selection matching is very important, the impact of the work of the machine is very large.
Analysis of Lubrication Failure of Directional Coupler
Lubrication is an indispensable flavoring agent for each machine. If the equipment is poorly lubricated, it will greatly reduce the efficiency of the machine and even damage the machine. Today, the Directional Coupler manufacturers will explain the Directional Coupler lubrication failure analysis
Directional Couplers are common for a few more
Directional Coupler lubricating oil cooler inlet temperature is too high fault and solution:
1, the bearing temperature is too high; check the bearing.
2, the working oil temperature is too high; check the equipment working environment and the transmission parts of any friction caused by oil temperature is too high.
3, the flow is too low; exclusion, increase traffic.
4, easy to melt plug melting, coupling efficiency is low; exclusion method, replace the fusible plug can be.
