How to perform airtightness testing on high-voltage equipment?

---

High voltage equipment is usually used under very high pressure, and manufacturers conduct pressure resistance testing, air tightness testing, and testing before leaving the factory. Below, the editor will introduce two commonly used and simple methods. Pressure drop detection method: This detection method generally requires customizing a Feentor airtightness detection table, which includes functions such as setting the online detection pressure, holding time, lower limit pressure, automatic unloading, etc. Its core component is ZTD or ZTT pneumatic booster pump, which boosts the original air or other gases to high pressure equipment to detect pressure or use pressure holding, and checks whether it falls outside the set lower limit pressure after a certain period of time. High voltage equipment has a certain pressure attenuation value, and any value higher than the specified value is considered unqualified and indicates leakage.

Please be sure to read the operating precautions for compressed air booster pump and gas booster pump.

The reciprocating frequency of the compressed air booster pump is about 900000 to 1.2 million times (requiring replacement of the sealing ring - high-pressure seal). The reciprocating frequency of the booster pump is about 30-60 times per minute. Generally speaking, it is recommended that customers stop the booster pump for 15 minutes after starting it for one hour to rest. This can prevent premature wear of the sealing ring caused by prolonged operation of the booster pump. The sealing rings used in the gas booster pump are imported sealing rings or Hong Kong Sida Hang sealing rings. The company has sufficient stock of sealing rings to meet customer needs. Attention: According to the output pressure calculation formula, the inlet pressure should not be too low. It is necessary to observe the changes in the inlet pressure of the double pressurized gas in a timely manner and replace the steel cylinder accordingly. It is recommended to install a filtering device at the inlet of the high-

What are the operating steps and precautions for using an air booster pump?

---

1、 Operation steps of air booster pump: Precautions for machine use: 1. Add lubricating oil to the oil mist device of the binary system. For the south, use 10 # or 20 # mechanical oil, and for the north, use antifreeze mechanical oil or low pour point hydraulic oil in winter. (Below) The core component of this gas boosting system is the pneumatic air booster pump of the pneumatic booster machine, which is independently developed by our company through the introduction of foreign technology. This pump has many characteristics such as high output pressure, easy adjustment, automatic pressure maintenance, and high cost-effectiveness, and has been widely used. By adjusting the regulating valve, the input pressure can be regulated, and the output gas can be continuously adjusted accordingly.
