電動(dòng)調(diào)節(jié)閥常見故障：
電機(jī)不轉(zhuǎn)
原因：電機(jī)線圈燒壞。如使用環(huán)境**，進(jìn)水或滲透有腐蝕性的氣體而造成短路或電機(jī)轉(zhuǎn)子卡死不動(dòng)，電機(jī)線圈就發(fā)熱、燒壞。
判斷故障方法：用萬用表測(cè)量電機(jī)引出線正、反和零線之間的電阻，正常值約為160Ω，如偏差過大或過小，就證明線圈已燒壞。電動(dòng)操作器一投入自動(dòng)，調(diào)節(jié)閥就處于全開或全關(guān)位置原因：調(diào)節(jié)閥反饋線路部分故障，無反饋電流輸出。
處理方法：檢查有無提供反饋線路的電源;檢查反饋線圈(差動(dòng)變壓器)的初級(jí)和次級(jí)是否斷路;檢查差動(dòng)變壓器的初級(jí)電壓和次級(jí)電壓是否正常。
暖氣管路溫度不夠，室溫過低。排除方法：進(jìn)水溫度低，提高進(jìn)水溫度。由物業(yè)檢查系統(tǒng)。進(jìn)回水閥門以里(靠近暖氣方向)漏水。排除方法：關(guān)閉進(jìn)回水閥門。通知安裝隊(duì)維修。進(jìn)回水閥門以外(靠近主管路)漏水。排除方法：通知物業(yè)半閉系統(tǒng)閥門;通知安裝隊(duì)進(jìn)行維修。方法一：先將進(jìn)水閥門關(guān)閉。打開跑風(fēng)放氣門排氣，有水溢出，關(guān)閉放氣閥。
方法二：將進(jìn)水閥門關(guān)閉3/4，再將回水閥門關(guān)閉后，打開放氣門排氣，有水溢出時(shí)半閉放氣閥。
電動(dòng)調(diào)節(jié)閥手動(dòng)操作費(fèi)勁：填料壓蓋過分?jǐn)Q緊，試一試松動(dòng)壓蓋;閥門內(nèi)部發(fā)生意外，拆卸閥門檢查
電動(dòng)調(diào)節(jié)閥沒顯示開度信號(hào)：開度信號(hào)線接觸**或斷線，檢查開度信號(hào)線的連接
執(zhí)行器不動(dòng)作， 電源燈亮而信號(hào)燈不亮。
處理方法：檢查輸入信號(hào)極性等是否正確;用對(duì)比互換法判斷控制模塊是否良好。
調(diào)節(jié)系統(tǒng)參數(shù)整定不當(dāng)導(dǎo)致執(zhí)行器頻繁振蕩。
處理方法：調(diào)節(jié)器的參數(shù)整定不合適，會(huì)引起系統(tǒng)產(chǎn)生不同程度的振蕩。對(duì)于單回路調(diào)節(jié)系統(tǒng)，比例帶過小，積分時(shí)間過短，微分時(shí)間和微分增益過大都可能產(chǎn)生系統(tǒng)振蕩。可以通過系統(tǒng)整定的方法，合理的選擇這些參數(shù)，使回路保持穩(wěn)定速度。
Motor does not turn
Reason: the motor coil burnt out. If use environment, water or penetration have corrosive gas and short-circuited or motor rotor motor coil is dead, fever, burnt out.
Methods: using a multimeter to judge fault lead wire is measured motor, and the resistance between neutral approximately 160 Ω, normal, such as too small or large deviation, will prove coil has burnt out. Automatic electric device, the regulator is an investment in the fully open or sexual position feedback circuit part: regulator, without fault feedback current output.
Treatment: check whether the power line; provide feedback, Inspection feedback coil (differential transformer) primary and secondary whether breakers, Check differential transformer's primary voltage and secondary voltage is normal.
Heating pipe temperature, temperature is too low. Method: the inlet water temperature is low, improve water temperature. By property inspection system. The valve in the backwater into (near the heating) is leaking. Method: shut into water valve. Notice installation group maintenance. In return valve (near the) is leaking. Method: notify property semiclosed system valve, Notice installation group. Methods: a water valve closed. Open the valve exhaust, running water is put, close valve.
Method 2: will fill the valve closed 3/4, again will return after the valve is closed, open valve, water overflow vent valve closed when half.
Motorized modulating manual operation difficulty: gland too tight, try a loose gland, The valve internal accident, remove valve check
Motorized modulating didn't show opening signal: opening line contact undesirable or break open degree, check the signal
Do not move, actuators and bright lights light source.
Check the input signal processing methods: polarity is proper; etc. By contrast swap method is good judgment control module.
Regulating system parameter setting to actuator frequent oscillation.
Processing methods: regulator parameter setting, will cause the system produces different degree of oscillation. For single loop control system, the ratio is too small, with integral time too short, differential time and differential gain over mostly may produce system. Through the method of system, the reasonable selection of these parameters and stable velocity loop.
