Gearless mill drives

The poles of the gearless or synchronous motor (also called wrap-around motor or ring motor) are directly installed on the pole flange of the mill shell, turning the mill body into the rotor. The stator is then wrapped around the mill. The gearless motor is fed by a cycloconverter which has a rated output frequency of around 5 Hz for the GMD drive.

How does a Gear Pump work? | What Is a Gear Pump?

The gear pump has the following components: Drive shaft; Seal; Inlet & Outlet ports; Driver gear; Drive gear; Housing Prime mover; Pressure relief valve; 1) Driver or Power Gear.

What is DC Drive? Working and Types of DC Drives

DC Drive Input: Some thyristor based DC drives operate on a single phase supply and use four thyristors for full wave rectification. For larger motors, three phase power supply is needed because the waveforms are much smoother. In such cases, six thyristors are needed for full wave rectification. Rectifier Bridge: The power component of a controlled …

Gear Pump: Working Principles, Function & Diagram | Linquip

The gear pump is among the most popular types of positive displacement pumps. Gear pumps are constructed with intermeshing gears that seal off a certain amount of liquid. The liquid is then transmitted as the gears rotate. This pump was invented around 1600 by Johannes Kepler. Pumping fluid through the hydraulic gear system is pulseless and …

Variable Frequency Drive Basics (Working Principle)

Variable Frequency Drive Basics (Working Principle) The basic configuration of a variable frequency drive is as follows. Each part of a variable frequency drive has the following function. A converter is a device to create the DC from the AC power supply. See the basic principle with the single-phase AC as the simplest example.

Service and Isolation Valve: Working Principle & Function

A service valve is a compression valve with a tap union fitting on one end and a compression end connected directly to the appliance on the other. A service valve and a tap connector are combined in the service valve. Isolation valves are squeezed on both ends. It can thus be employed in the middle of a pipe segment.

What is a Gear Pump: Working, Types, Advantgaes,

The gear pump definition is, it is a PD (positive displacement) rotating pump which assists you to move water otherwise fluid with the help of inbuilt gears. This type of pump includes two or more gears that create vacuum force to drive the liquid within the pump. This pump can be built with different parts like shaft, rotors, and casing.

How do pumps and air compressors work?

Gear pumps. In another design, called a gear pump, the vanes and impellers are replaced by two or more large screws or gears that mesh and rotate in opposite directions, pulling fluid around them as they go. Artwork: A rotary pump can use meshing gears or screws to move fluid, much like a hydraulic motor. Auger pumps

Particle Image Velocimetry: Basics, Developments and Techniques

PIV measurements were carried out at airflow velocities of approximately 50 m/s and temperatures of less than –170 °C with particle sizes less than 1 µm. In the DLR tests, a single-oscillator Nd:YAG double-pulse laser from InnoLas was used for illumination. This new design made it possible to generate two light pulses with a defined time ...
