1.5kw Split Type Vacuum Pre-Extraction Machine, Exhaust Rate 40m³/H, 2.0pa Ultimate Pressure

Product Introduction

As the core equipment of industrial vacuum engineering, VET-003 breaks the limitations of traditional design with its split structure: the separated control chassis can be deployed independently of the host, suitable for compact production lines or elevated platforms; the host supports any vacuum pump model matching, compatible with different working conditions. The equipment integrates real-time display of digital vacuum value, intelligent positioning of vacuum degree and automatic alarm system, which can achieve high-precision and automated operation from precision workpiece detection to pre-vacuuming of large equipment, and significantly improve the vacuum processing efficiency of the production line.

Product Features

Space optimization design: The volume of the separated control chassis is reduced by 30%, saving 50% of the installation space, and is suitable for narrow production lines and dense equipment layout.

Flexible and free layout: The control chassis can be remotely installed by extending the cable (up to 10 meters), and supports multi-form deployment such as wall hanging and equipment rack fixing.

Strong pump body compatibility: The host reserves a universal interface, which supports seamless docking of any brand of vacuum pumps such as rotary vane, vortex, diaphragm, etc., without additional adaptation and modification.

High-precision detection capability: The Pirani vacuum sensor has an accuracy of ±1.5% FS, and displays the vacuum value fluctuation of 0.1Pa in real time, meeting the laboratory-level detection standards.

Intelligent automatic control: supports dual trigger modes of vacuum degree (0-100kPa arbitrarily set) and time, automatically stops when the standard is met, and alarms with sound and light for abnormal working conditions and locks the fault point.

Multi-scenario adaptability: Standard VG40 air inlet and M50x1.5 exhaust port, compatible with multiple types of workpiece interfaces such as refrigerator pipelines, vacuum coating chambers, drying ovens, etc.

International reference standards

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

ISO 21511:2018 "Vacuum Technology - Pirani Vacuum Gauge - Calibration and Measurement Methods": Standardizes the temperature compensation algorithm and precision calibration process of Pirani sensors to ensure the international mutual recognition of vacuum measurement data.

IEC 60529:2013 "Enclosure Protection Grade (IP Code)": The control chassis protection grade reaches IP54, which effectively resists dust and splashing water and adapts to the complex environment of industrial workshops.

ASME BPVC Section VIII-1:2021 "Pressure Vessel Construction Rules": The materials and welding processes of the host pressure-bearing parts comply with the standards of the American Society of Mechanical Engineers to ensure the structural safety under high-pressure conditions.

GB/T 25754-2010 "Vacuum Technology - Vacuum System Leak Detection Method": The leak detection function complies with the Chinese national standard and supports accurate positioning of the minimum leak rate of 5×10⁻⁵Pa・m³/s.
