Vacuum Pumping And Nitrogen Filling Device Ultimate Pressure ≤-100kpa Vacuum Rate 28l/S Intelligent Double Station

Vacuum Pumping And Nitrogen Filling Device Ultimate Pressure ≤-100kpa Vacuum Rate 28l/S Intelligent Double Station

Product Introduction

As the core equipment for vacuum engineering and gas processing, VET-005 adopts the three-stage intelligent control logic of "vacuuming - filling with nitrogen - maintaining pressure": the front 28L/s mechanical vacuum pump can quickly empty the cavity air within 3 minutes, and the DN35 large-diameter exhaust port improves efficiency; the nitrogen system integrates a high-precision pressure reducing valve and a mass flow meter, supports 0.1-0.7MPa stepless pressure adjustment, and ensures that the nitrogen filling accuracy reaches ±2% FS. The equipment is equipped with a double-station independent operation interface as standard, which can process 2 groups of workpieces with different process parameters at the same time, significantly improving the automation level of the production line. The body is made of 304 stainless steel, which is resistant to corrosive gas erosion and suitable for humid and dusty industrial environments.

Product Features

Dual-station parallel processing: Independently control 2 groups of vacuuming and nitrogen filling processes, support synchronous operation of different pressure parameters, and improve efficiency by 50%.

Ultimate vacuum performance: no-load ultimate pressure ≤-100KPa (equivalent absolute pressure 10kPa), meeting the requirements of precision processes such as high vacuum welding and chip packaging.

Precise nitrogen control: built-in MFC mass flowmeter, nitrogen flow 0-500L/min adjustable, pressure stability ±0.5%, to avoid damage to workpieces caused by overcharging.

Safety protection system: equipped with vacuum overload protection, nitrogen leakage sound and light alarm, and grounding fault detection to ensure safe operation; the ergonomic design of the exhaust port 850mm from the ground reduces bending fatigue.

Fast changeover capability: The exhaust port/nitrogen port adopts a quick-plug DN35/DN8 interface, which can complete the switching of workpiece fixtures of different specifications within 5 minutes, and is suitable for small-batch production of multiple varieties.

Data traceability function: standard RS485 communication interface, real-time recording of vacuum degree, nitrogen pressure, operation time and other data, supporting MES system docking and process review.

International reference standards

The equipment strictly follows the following international specifications to ensure performance, safety and data compliance:

ISO 21511:2018 "Vacuum Technology - Calibration Methods for Pressure Measurement Equipment": The regular calibration process of vacuum sensors complies with international standards, and the pressure measurement accuracy is ±0.5% FS.

EN 737:2019 "Industrial Valves - Pressure Test": The pressure test of nitrogen system valves complies with EU standards to ensure no leakage under 0.7MPa working conditions.

IEC 61010-1:2010 "Safety Requirements for Laboratory Equipment": The electrical system has passed the overload protection and leakage circuit breaker certification, and the grounding resistance is ≤4Ω, meeting the dual safety levels of laboratory and industry.

GB/T 15823.10-2020 "Vacuum Technology - Leakage Detection Method for Nitrogen Filling Packages": The pressure holding test function after nitrogen filling complies with Chinese national standards and supports a minimum leak rate detection of 5×10⁻⁵Pa・m³/s.
