Hydraulic pressure burst testing machine

Description

What is a Hydrostatic Burst Pressure Test Machine?

This equipment is a professional fluid pressure testing device that integrates hydrostatic pressure testing, burst pressure testing, and leak testing. It is mainly used to verify the structural strength and sealing performance of various pressure-bearing components and pressure vessels.

Based on the pneumatic boosting principle, it is equipped with a digital display control system and an enclosed protective cabinet. It combines the precision of automated control with the safety of manual emergency operation, making it a core device for product quality verification in the automotive, construction machinery, fire protection, energy, and other industries.

Core Advantages

• Precision Control & Monitoring: Digital display + dual pressure gauges for real-time pressure monitoring; test data is traceable, with pressure control accuracy ≤ ±0.5% FS.
• Safety Protection: Integrated pressure relief valve and enclosed cabinet effectively block the risk of high-pressure medium leakage, ensuring operator safety.
• Flexible Adaptability: Supports multiple test media such as water and hydraulic oil, adapting to workpieces of different materials and specifications.
• Easy Mobility: Equipped with lockable universal casters at the bottom, enabling quick transfer between workshop stations to improve testing efficiency.

Working Principle

This equipment is based on the reciprocating principle of a pneumatic booster pump, achieving high-pressure output of low-pressure media through pneumatic drive. The core process is as follows:

1. Power Connection: Connect 0.4~0.8MPa industrial compressed air to the equipment’s drive port, and adjust the air pressure regulator to preset the test pressure.
2. Medium Boosting: The pneumatic booster pump draws in and compresses low-pressure test medium (e.g., water, hydraulic oil) to raise its pressure to the set value.
3. Automatic Pressure Holding: When the pressure reaches the preset value, the equipment automatically stops boosting and enters the pressure-holding state, monitoring pressure decay in real time.
4. Test Evaluation: If the pressure decay during the holding period is within the allowable range, the hydrostatic/leak test is judged as qualified; for burst testing, continue boosting until the workpiece ruptures, and the pressure gauge automatically records the burst pressure value.
5. Safe Pressure Relief: After the test, slowly release residual pressure in the pipeline via the manual pressure relief valve to avoid pressure shock.
