An electrical system is like a pipe system. The voltage is like a liquid pressure. The current is like the flow rate of a liquid, and the electrical insulation is like a wall. Insulation prevents leakage of electrons from the conductor - the size of the effect is represented by the insulation resistance. An effective insulation resistance system has a high resistance value and is usually larger than a few megohms (MΩ). Poor insulation systems have lower insulation resistance.

To find leaks in the piping system, you need to pressurize it. Since leakage is most easily detected when the water pressure is highest, you cannot close tap water to check for leaks. However, you will limit the tap water that is available so that you will not be able to spray too much water around when you find a large leak. The ideal test is to provide a limited amount of water under high (but not particularly high) pressure. This is exactly what the electrical insulation tester does.

The insulation tester (Megohmmeter) applies a DC voltage to the insulation system and measures the resulting current. In this way it is possible to calculate and display the resistance value of the insulation (the extent to which the insulation confines the current in the wire, or the extent to which current is prevented from leaking).

Insulation testers (Megohmmeters) typically output test voltages of 50 V, 100 V, 250 V, 500 V, or 1000 V. Just as in a pipeline system, the purpose is to provide a pressure (voltage) that is not particularly high. We hope to find the existing leaks, but we do not want to create new leaks by overstressing the system. Lower voltages are used in low-voltage systems such as telephones, networks, or control lines; higher pressures are used to test power system insulation.

This equipment is divided into vertical and horizontal structure, used for semi-finishing process of steel ball,

 Main structural features

1)  The rotation of main shaft and turntable adopt frequency conversion speed regulation;

2)   Hydraulic drive pressure, mechanical pressure preservation by compression spring and constant pressure nut locking;

3)   Adopt end face bearing with high capacity;

4)   The main shaft bearing adopts the mechanical seal structure, which eliminates the hidden danger of the main shaft oil leakage;

5)  The main transmission uses reduction box with a pair of increase modulus and widening gears. The power is transmitted to the  spindle through the output shaft of the bevel gear. The transmission structure is simple and reliable;With mechanical grinding  wheel dresser driven by belt motor;

6)  Adopt small cycle processing in accordance with the requirements (without turntable).

1)Horizontal layout, large cycle machining;

2)L type low gravity structure is adopted, and the moving plate is moving pressurization;

3)Side mounted flat turntable;

4)The opening size of the ball plate, the positioning size of the ball plate, types of turntable (plate or incline), the amount of ball loading, the spindle speed and the power of the main motor can be customized according to the requirements of the customers.
