GE通用電氣 PQM-T20-C 超速保護(hù)器編碼器

一、概述

PQM-T20-C 超速保護(hù)器編碼器是由GE通用電氣公司生產(chǎn)的一款高性能編碼器，旨在提供精準(zhǔn)、可靠的速度檢測和超速保護(hù)功能。它廣泛應(yīng)用于工業(yè)自動(dòng)化、數(shù)控機(jī)床、電力、機(jī)械加工等領(lǐng)域，對于確保設(shè)備的安全運(yùn)行和提高生產(chǎn)效率具有重要意義。

二、主要功能

1. 速度檢測：通過精確測量旋轉(zhuǎn)軸的轉(zhuǎn)速，PQM-T20-C編碼器可以實(shí)時(shí)反映設(shè)備的運(yùn)行狀態(tài)，為控制系統(tǒng)提供準(zhǔn)確的速度反饋。
2. 超速保護(hù)：當(dāng)檢測到設(shè)備的轉(zhuǎn)速超過預(yù)設(shè)的安全閾值時(shí)，PQM-T20-C編碼器會(huì)立即觸發(fā)超速保護(hù)機(jī)制，通過輸出信號使控制系統(tǒng)采取相應(yīng)的措施，如減速、停機(jī)等，以避免設(shè)備因超速而損壞或引發(fā)安全事故。

三、技術(shù)特點(diǎn)

1. 高精度：PQM-T20-C編碼器采用先進(jìn)的光電檢測技術(shù)，具有較高的測量精度和穩(wěn)定性，能夠準(zhǔn)確反映設(shè)備的實(shí)際轉(zhuǎn)速。
2. 高速運(yùn)動(dòng)性能：編碼器在高速運(yùn)動(dòng)下依然能夠保持穩(wěn)定的性能，不易受到雜音、電磁干擾等因素的影響。
3. 耐磨損、長壽命：編碼器采用耐磨損材料和結(jié)構(gòu)設(shè)計(jì)，能夠在惡劣的工業(yè)環(huán)境下長時(shí)間穩(wěn)定工作，減少故障率和維護(hù)成本。
4. 數(shù)字信號輸出：編碼器輸出的是數(shù)字信號，易于與控制系統(tǒng)進(jìn)行連接和集成，提高了系統(tǒng)的整體性能和可靠性。

四、應(yīng)用領(lǐng)域

PQM-T20-C超速保護(hù)器編碼器廣泛應(yīng)用于各種需要精確速度測量和超速保護(hù)的工業(yè)自動(dòng)化系統(tǒng)中，如數(shù)控機(jī)床、電機(jī)馬達(dá)、輸送帶等。在這些應(yīng)用中，PQM-T20-C編碼器發(fā)揮著至關(guān)重要的作用，確保了設(shè)備的安全運(yùn)行和高效生產(chǎn)。

GE General Electric PQM-T20-C overspeed protector encoder

I. Overview

The PQM-T20-C Overspeed Protector encoder is a high-performance encoder manufactured by GE and designed to provide accurate, reliable speed detection and overspeed protection. It is widely used in industrial automation, CNC machine tools, electric power, mechanical processing and other fields, to ensure the safe operation of equipment and improve production efficiency is of great significance.

Two, the main function

Speed detection: By accurately measuring the rotational speed of the rotating shaft, the PQM-T20-C encoder can reflect the operating status of the device in real time, providing accurate speed feedback to the control system.

Overspeed protection: When the speed of the device is detected to exceed the preset safety threshold, the PQM-T20-C encoder will immediately trigger the overspeed protection mechanism, and the control system will take corresponding measures through the output signal, such as deceleration, shutdown, etc., to avoid equipment damage or cause safety accidents due to overspeed.

3. Technical characteristics

High precision: PQM-T20-C encoder adopts advanced photoelectric detection technology, has high measurement accuracy and stability, and can accurately reflect the actual speed of the equipment.

High-speed motion performance: The encoder can still maintain stable performance under high-speed motion, and is not easily affected by noise, electromagnetic interference and other factors.

Wear resistance and long life: The encoder uses wear resistant materials and structural design, which can work stably in harsh industrial environments for a long time, reducing the failure rate and maintenance costs.

Digital signal output: The encoder outputs a digital signal, which is easy to connect and integrate with the control system, improving the overall performance and reliability of the system.

4. Application field

The PQM-T20-C Overspeed protector encoder is widely used in various industrial automation systems that require accurate speed measurement and overspeed protection, such as CNC machine tools, motor motors, conveyor belts, etc. In these applications, the PQM-T20-C encoder plays a vital role in ensuring the safe operation and efficient production of the equipment.
