Ultimate Guide to Reciprocating Compressor Capacity Control Njira

Ma compressor obwerezabwerezaamapangidwira kuti azigwira ntchito pachimake, komabe zochitika zenizeni zimafuna kusintha kosinthika kuti zigwirizane ndi zofunikira. Ku Xuzhou Huayan Gas Equipment, timakhazikika pakupanga njira zowongolera mphamvu zomwe zimakwaniritsa bwino ntchito zosiyanasiyana zamafakitale.

1. Kuthamanga Kwambiri (Variable Speed ​​Drive)

Mfundo Yofunika: Imasintha kompresa RPM kuti isiyanitse mpweya wotuluka.
Ubwino:

• Kupitilira, kuwongolera koyenda kuchokera ku 40% mpaka 100%.
• Kuchepetsa mphamvu yamagetsi pa katundu wochepa
• Imasunga ma ratios a pressure mu magawo 18
  Zolepheretsa:
• Makina okwera mtengo a VSD amagalimoto akulu (> 500 kW)
• Kuthira mafuta ndi ma valve flutter pansi pa 40% RPM
• Kuwonjezeka kwa ma bearing / crankshaft kumathamanga kwambiri 46
  Zabwino Kwambiri: Mayunitsi oyendetsedwa ndi ma turbine kapena ma compressor apakatikati omwe amasinthasintha pafupipafupi.

2. Bypass Control

Mfundo Yofunika: Imazunguliranso mpweya wotuluka kuti uyamwe kudzera mavavu.
Ubwino:

• Kuyika kosavuta ndi mtengo wotsika wakutsogolo
• 0-100% yathunthu yosinthira kuyenda
• Kuyankha mwachangu pachitetezo cha maopaleshoni 48
  Chilango cha Mphamvu:
• Zimawononga 100% ya mphamvu yopondereza pa gasi wobwerezabwereza
• Imawonjezera kutentha kwa 8-15 ° C, kuchepetsa mphamvu
• Zosakhazikika pakugwira ntchito mosalekeza 16

3. Kusintha Pocket Yachilolezo

Mfundo Yofunika: Imakulitsa kuchuluka kwakufa mu masilinda kuti muchepetse mphamvu ya volumetric.
Ubwino:

• Kugwiritsa ntchito mphamvu kumayenderana ndi zotsatira zake
• Kuphweka kwamakina pamapangidwe amitundu yokhazikika
• Ndikoyenera 80-100% yochepetsera mphamvu 110
  Zovuta:
• Kutsika kochepa (<80% kutsika kwambiri)
• Kuyankha kwapang'onopang'ono (20-60 masekondi kuti kukhazika mtima pansi)
• Kukonza kwakukulu kwa matumba osindikizidwa a piston 86

4. Mavavu Otsitsa

a. Kutsitsa kwathunthu kwa Stroke

• Ntchito: Imagwira ma valve olowetsa otseguka panthawi yonse ya kupsinjika
• Zotulutsa: 0%, 50% (ma silinda ochita kawiri), kapena 100%
• Kuletsa: Kuwongolera molakwika kokha; zimayambitsa kutopa kwa valve 68

b. Kutsitsa pang'ono-Stroke (PSU)
Kusintha Mwachangu:

• Kuchedwetsa kutsekedwa kwa ma valve olowetsa panthawi ya kupanikizana
• Imakwaniritsa 10-100% kusinthasintha koyenda kosalekeza
• Imapulumutsa mphamvu 25–40% poyerekeza ndi bypass popanikiza POKHALA mpweya wofunikira 59
  Ubwino Waukadaulo:
• Kuyankha kwa Millisecond kudzera pa ma electro-hydraulic actuators
• Palibe zoletsa kuthamanga (mpaka 1,200 RPM)
• Yogwirizana ndi mipweya yonse yopanda mphamvu

Kodi Mwakonzeka Kusintha Kugwiritsa Ntchito Kwanu Kopanikizika?
[Lumikizanani ndi Huayan Engineers]kuti mufufuze zaulere za mphamvu ndi kukhathamiritsa kwa compressor.
