Limitorque TM QX智能閥門執(zhí)行器
下一代智能四分之一轉(zhuǎn)向執(zhí)行器的安全性和可靠性的充分措施
The Flowserve Limitorque QX quarter-turn, smart electronic valve actuator mimics the state-of-the-art, non-intrusive, multi-turn MX actuator by including a patent-pending absolute encoder for trackingposition without the use of troublesome batteries. The QX design provides enhanced safety andreduced downtime through improved diagnostics, built-in self-test (BIST) featuresand LimiGard ™fault protection.
The QX design builds on more than 14 years of experience with proven Limitorque MX technology—the first-generation double-sealed electronic valve actuator from Flowserve designed to providecontrol, ease of use and accuracy. The QXincludes all the user-preferred features of the MX in aquarter-turn, smart actuator package.
Limitorque QX的特點(diǎn)包括:
•An absolute encoder that simplifies valve automation from configuration and setup into
normal operations, diagnostics and troubleshooting. The QX encoder employs system-on-chip
technology using a contactless magnet that excites Hall effect devices to provide redundant,
12-bit resolution over 360 degrees. This redundancy, part of the BIST feature, means the device
can continue to function reliably until a number of faults has been accumulated.
• Advanced brushless DC motors eliminate sparks, reduce mechanical and electrical noise, and
dissipate heat better than motors with brushes. Unique to the industry, the brushless actuator
design lasts longer than conventional motors and allows for more accurate positioning while
permitting a global range of voltages (single-phase and three-phase ACV and DCV) to be
connected without modification.
• Graphical dot-matrix display allows 180-degree rotation of text, diagnostic graphs and supports 10
languages: English, Spanish, French, Italian, German, Portuguese, Japanese (Katakana), Mandarin,
Russian and Malay.
• Optional Bluetooth ® wireless connectivity with a range up to 10 meters. When used with
Flowserve Limitorque Dashboard ™ Windows ® -based software, diagnostic information is easily
transferred to a PDA, laptop computer or cell phone.
• Network communications such as Modbus, Foundation Fieldbus H1, DeviceNet, Profibus DP_V1
with redundancy and Profibus PA offer the user bit strobe I/O messaging and a host of other
benefits. A Device Type Manager (DTM) is also available for Profibus and Foundation Fieldbus.
• Available in five distinct sizes from 100 ft-lbs (136Nm) to an industry-leading
1500 ft-lbs (2040 Nm).
• The QXM (multi-turn) is also available for unique applications that require up to 20 turns maximum
in a small, compact and lower torque electronic actuator.
• Includes innovative handwheel parallel to the LCD screen to permit ease of manual setup and
operation and the ability to be installed in areas with limited space.
