The relationship between water pressure test and air pressure test

---

According to the national standard GB/T13927 of the People's Republic of China, containers must undergo pressure testing, including airtightness testing, hydrostatic testing, and burst testing. The air tightness test should be conducted at 1.15 times the operating pressure, the water pressure test should be conducted at 1.25 times the operating pressure, and the burst test pressure should be at least 1.4 times the operating pressure. Let's explain their relationship below.

What is the reason for the decrease in outlet pressure of compressed air booster pump during pneumatic operation

---

The original compressed air pressure in the factory was 6 bar, and after passing through the compressed air booster pump, the outlet pressure became 6 bar. However, when the compressed air booster pump was turned on, the outlet pressure did not increase but instead decreased. But when the outlet air equipment was turned off, the pressure could still increase. What's the reason for this? I believe many manufacturers who are using compressed air booster pumps for the first time have encountered this phenomenon. Below, I will explain to you which situations can cause this phenomenon.

Compressed air booster pump or compressed air booster system for secondary pressurization of compressed air

---

As the name suggests, a compressed air pump is a type of pump that boosts the pressure of compressed air. However, compressed air booster pumps also have their limitations, such as the ZTV02 air booster pump, which doubles the pressure of compressed air after passing through the air booster pump. If the pressure exceeds 2 times, a higher ratio air booster pump should be selected. For example, ZTV05 has a 5-fold boost. For higher pressures, please consult engineers from Taizhou Fuente.

Why use Fuente hydraulic testing machine, gas-liquid booster, and liquid booster valve? practical.

---

Hydraulic testing machine, gas-liquid booster, liquid booster valve, economical and practical, is an experiment used to apply pressure continuously through liquid or air on the surface of a certain specification of polymer sheet (such as film, leather, etc.) or the inner surface of pipes or containers, test the rated pressure when the sample suddenly ruptures, and calculate the bursting strength of the material. Mostly used for non-destructive testing of products

Gas driven liquid booster pump - Water pressure testing equipment must

---

Hydraulic testing equipment - Gas driven liquid booster pump, also known as gas-liquid booster pump, uses a single gas controlled non-equilibrium gas reversing valve to achieve automatic reciprocating operation of the pump. The pump body drive cylinder is 80mm, 100mm, 125mm, 160mm, 250mm, and the pump drive part is generally made of aluminum alloy, and the liquid receiving part is made of 304 stainless steel. Different materials can also be customized according to customer requirements. The end cover is oxidized to ensure the appearance and durability of the pump.
