According to the normal use method of the measuring pen, it is usually impossible to distinguish the charged nature of the electrical housing, because the measuring pen is usually used to measure the charged nature of the electrical housing. Whether it is leakage or normal charging, its neon bulb will glitter. In order to enable the measuring pen to determine the charged nature of the electrical housing, the method of adding a ground wire to the pen can be selected.

The manufacture of motor housing is a very important part of motor production. The materials of motor shell generally include cast iron, cast aluminum alloy, steel pipe, steel plate, etc. The main purpose is to protect the motor from rain, corrosion, rust and other environmental impacts. In a humid environment, ordinary motor casing materials are prone to corrosion and rust, and the waterproof performance of the motor depends on the protection of the casing. After the motor is eroded by water, it will lead to unstable use or scrapping of the motor. Therefore, the waterproof housing of the motor is very important.

What should be paid attention to when painting Dalian motor housing

1. Automatic coating mode can be selected for construction, and automatic coating machine can be used to seal the tank. This construction method is more efficient and convenient for transportation and storage.

2. The same color shall be used for the same object and the same batch of products shall be selected to avoid obvious color difference.

3. Test the spraying effect before construction to see whether the spraying is uniform and whether the equipment is faulty. Avoid different spraying effects.

4. Protective clothing must be worn when spraying, because harmful substances will be produced when the paint volatilizes. If it is not protected, it will cause great harm to employees.

The dual channel air tightness testing equipment can quickly detect ok/ng products, and can detect two products at the same time, with high detection efficiency. Through the waterproof protection of the motor shell, water can be prevented from entering the motor to a great extent. Using the traditional bubble water to detect the sealing of the motor shell is inefficient, not intuitive, and some sealing problems are difficult to find. The air tightness testing equipment used will not have this problem, which is a new emerging sealing testing technology. It can efficiently and quickly detect the waterproof grade, sealing degree and other important product quality indicators.

The accuracy and applicability of the smelting process and its application for the shell of micro motor shall be demonstrated. After China's reform and opening up and accession to the WTO, China has greatly accelerated its pace of catching up with the world. Many manufacturing and processing skills have developed rapidly. In order to meet the increasing process requirements of high-strength thin-wall iron castings, many manufacturers have introduced world-class skills and equipment, and the casting process of micro motor casing has also been comprehensively updated and greatly improved.
