Core Product Competitive Advantages

1. Multi-Station Independent Parallel Test Architecture
   Configurable 2~8 separate test pipelines, each station equipped with independent pressure sensor, temperature circulation unit and solenoid valve control module. Operators can load different specifications of hose samples on each station to carry out burst, constant pressure holding and high-temperature aging tests simultaneously, which greatly shortens the batch inspection cycle and improves laboratory daily throughput.
2. Dual Control Modes (PLC Touch + PC Software)
   Supports three operation switching modes: manual single-point control, touch PLC automatic program control and computer full-data acquisition control. On-site simple test tasks can be completed directly via touch panel; mass data archiving, curve overlay comparison and standardized report export rely on matched industrial computer software, adapting flexible production inspection and laboratory R&D testing demands.
3. ±1% Ultra-Stable Constant Pressure Compensation System
   High-precision pressure closed-loop servo adjustment unit, real-time pressure supplement when medium volume changes after hose expansion or micro leakage, constant pressure control accuracy within ±1% full scale. Linear slow pressurization function avoids instantaneous pressure impact leading to premature hose rupture, ensuring authentic critical burst pressure data.
4. Integrated Constant Temperature Circulation Medium Tank
   Built-in heating and circulation integration module, adjustable test medium temperature range 40~150℃, circulating water/oil medium evenly wraps the outer wall of the test hose. It reproduces high-temperature working environment of engine cooling pipes, fuel hoses and heating pipelines, realizing high-temperature pressure resistance and aging leakage comprehensive evaluation.
5. Full Automatic Data Recording & Curve Storage
   The industrial computer synchronously collects real-time pressure, temperature and time signals of each station, automatically drawing pressure-time characteristic curves during pressurization, constant pressure and burst stages. All test data can be permanently stored, support single/batch data recall, curve zoom and comparison, one-click export editable PDF inspection reports for factory quality filing.
6. Multi-Link Full Safety Protection Mechanism
   Equipped with overpressure automatic pressure relief, overtemperature power-off protection, pipeline rupture emergency cut-off valve and test chamber isolation safety baffle. When the hose bursts suddenly during the test, the system instantly cuts off the high-pressure medium supply to avoid equipment damage and operator safety accidents; all high-pressure pipelines adopt thickened anti-explosion stainless steel tubes.

Standard Complete Test Operation Flow

1. Equipment Pre-Inspection & Parameter Setting
   Connect medium circulation pipeline and high-pressure test pipeline, power on the dual control system; set target pressure, constant pressure holding duration and medium temperature on touch screen or computer, start preheating circulation to stabilize medium temperature.
2. Hose Sample Clamping & Sealing Installation
   Install the two ends of the hose sample on the standard quick-connect high-pressure fixture, lock the sealing joint to eliminate medium leakage at the interface during pressurization, close the safety isolation baffle of the test station.
3. Medium Filling & Air Exhaust
   Start the circulation pump to fill the hose inner cavity with test medium, fully exhaust internal residual air to prevent air compression from interfering with pressure test accuracy, close the exhaust valve after completion.
4. Automatic Pressurization / Constant Pressure / Burst Test
   Select test program: constant pressure aging test or linear pressurization burst test. The system automatically boosts pressure, supplements pressure in real time to maintain set value, and continuously records full-process pressure-temperature curve data.
5. Automatic Data Capture After Sample Rupture
   When the hose bursts or the set holding time ends, the system automatically cuts off high-pressure medium, records the critical burst pressure or leakage pressure value, stores all curve data synchronously.
6. Data Export & Equipment Cleaning
   Call test records on the computer end to generate and print inspection reports; drain residual medium inside the hose fixture and circulation pipeline after testing, clean the test station and cut off power supply.
