Hydrostatic Pressure Testing Machine for Plastic Pipes, Fittings and Valves
Application
The Hydrostatic Pressure Testing Equipment is engineered for determining the internal pressure resistance of plastic pipes, pipe fittings and valves under constant temperature conditions. This essential testing device serves manufacturers, scientific research institutions, and quality control authorities for performance inspection and measurement of test specimens.
Key Features
This precision equipment features advanced pressure control components and automated pressure charging/discharging modules. The system utilizes MCU microcomputer-based regulation with a high-resolution, high-speed ∑-delta 16-bit ADC chip for real-time data communication and adaptive pressure control.
Pressure Station
The core pressure station delivers stable pressure to the main testing unit, with minimum pressure thresholds exceeding specimen requirements. Features an imported American plunger pump with large flow rate, low noise, high pressure resistance, and maintenance-free operation.
Water Tank System
Constructed with 304# stainless steel, the water tank integrates electric opening mechanisms, self-circulation modules, heating units, automatic water replenishment systems, and thermal insulation components for comprehensive liquid circulation and temperature preservation.
Temperature Control
Precisely regulates water temperature with independent functional modules for real-time display and temperature setpoint adjustment. Maintains optimal liquid levels and ensures consistent test temperatures throughout the entire testing process.
Software System
Connected via RS232 serial interface, the software supports comprehensive operational functions including test parameter configuration, equipment calibration, pressure relief, zero calibration, amplitude adjustment, real-time test curve plotting, full-process data logging, and standardized test report printing.
