【Discussion on HaiChuan Equipment Turning Devices】02: What on earth is a turning device? Calling for pictures of turning gear devices
Thread Content
Before starting general operating equipment, it is usually necessary to turn the shaft by hand first; however, some equipment is equipped with such a mechanism while others do not. Large centrifugal units and large pumps generally are equipped with an inching device, while small centrifugal pumps can usually be turned by hand and do not require such a device. So the question is, what exactly is a turntable device? Everyone is welcome to provide additional information. One more question: is the turning gear installed by the manufacturer, or does the owner need to have it installed? －－－－－－－－－－－－－－－－－－－－－－－－－－－－ For more series posts, click the link below.

What is a turning gear? It’s something that’s actually used with the turbine unit; the turning gear is provided by the manufacturer
It is a deceleration mechanism that replaces manual cranking, thereby reducing the workload on workers
Generally, large-scale units should be equipped with a turning gear system. The principle is the same as that of manual operation; it’s just that an automatic motor is used to drive the turning gear, eliminating the need for manual operation back and forth. For small pumps and motors, manual turning is quite easy, so there is no need for an additional system
Was this turning system originally included by the manufacturer, added at the owner’s request, or recommended by the manufacturer to the owner?
A motor is needed, right? How should the power of this motor be determined? What should be the appropriate speed for rotating the disk?
No points either; the answer is boring, right?:P
That is, two sets of speed reduction equipment. The motor drives the pinion gear, which in turn drives the gear wheel. Generally, large steam turbines/reciprocating engines are equipped with a barring device. The rotation speed depends on the design. There are requirements for the speed of the turbine turning gear.
Crankshaft turning methods include hydraulic crankshaft turning, intermittent crankshaft turning, and manual crankshaft turning!
Pictures speak louder than words; feel free to share pictures of various turntable equipment
