Ultimate Guide kune Reciprocating Compressor Capacity Control Methods

Reciprocating compressorsdzakagadzirirwa kuita kwepamusoro-soro pakuremerwa kukuru, asi mashandiro epasirese chaiwo anoda shanduko yekuyerera kuenderana nezvinodiwa. KuXuzhou Huayan Gasi Equipment, isu tine hunyanzvi mukugadzira akaenderana masimba ekugadzirisa zvigadziriso izvo zvinogonesa kushanda zvakanaka pane akasiyana maindasitiri ekushandisa.

1. Speed ​​​​Regulation (Variable Speed ​​​​Drive)

Nheyo: Inogadzirisa compressor RPM kuti isiyane negasi.
Zvakanakira:

• Inoenderera, mutsara kuyerera kwekutonga kubva ku40% kusvika ku100% kugona
• Pedyo-yakaenzana simba rekuchengetedza pamitoro yakaderedzwa
• Inochengetedza chiyero chekumanikidza mumatanho 18
  Kuganhurirwa:
• Yakakwira-inodhura VSD masisitimu emamota mahombe (> 500 kW)
• Nyaya dzekuzora uye valve flutter pazasi 40% RPM
• Kuwedzera kubereka / crankshaft kupfeka pakumhanya kwakanyanya 46
  Zvakanakisisa Kune: Turbine-inotyairwa mayunitsi kana epakati-saizi compressor ane anogara achichinja mitoro.

2. Bypass Control

Nheyo: Inodzokorodza kubuda kwegasi kusveta kuburikidza nemavharuvhu.
Zvakanakira:

• Kuisa nyore nemutengo wakaderera kumusoro
• Yakazara 0-100% kuyerera kugadzirisa kugona
• Kukurumidza kupindura kwekudzivirira kwekuvhiya 48
  Energy Penalty:
• Inorasa 100% yesimba rekumanikidza pagasi rakadzokororwa
• Inowedzera tembiricha yekusveta ne8-15 ° C, inoderedza kugona
• Kusagadzikana kwekuenderera mberi kwekushanda 16

3. Clearance Pocket Adjustment

Nheyo: Inowedzera vhoriyamu yakafa mumasilinda kuti ideredze kugona kwevhoriyamu.
Zvakanakira:

• Mashandisirwo emagetsi anoyera mutsara nezvinobuda
• Mechanical nyore mune yakagadziriswa-vhoriyamu madhizaini
• Yakanakira yakatsiga-mamiriro 80–100% kugona kugadzira 110
  Zvakaipa
• Yakaganhurirwa turndown range (<80% inodonha zvakanyanya kushanda zvakanaka)
• Kupindura kunononoka (20–60 masekonzi ekumanikidza kugadzikana)
• Kugadziriswa kwepamusoro kwepiston-yakavharwa mahomwe akasiyana 86

4. Varururu Unloaders

a. Full-Stroke Unloading

• Basa: Inobata mavharuvhu ekutora akavhurika mukati mekumanikidza
• Kubuda Matanho: 0%, 50% (mbiri-anobata masilinda), kana 100%
• Limitation: Coarse control chete; zvinokonzera kuneta kwevhavha 68

b. Partial-Stroke Unloading (PSU)
Kubudirira Kwekuchinja:

• Kunonoka kuvhara valve yekupinda panguva yekumanikidza
• Inowana 10-100% inoenderera kuyerera modulation
• Inochengetedza 25–40% simba maringe nekudarika nekudzvanya CHETE inodiwa gasi 59
  Technical Superiority:
• Millisecond mhinduro kuburikidza ne electro-hydraulic actuators
• Hapana kurambidzwa kumhanya (kusvika 1,200 RPM)
• Inoenderana nemagasi ese asina-reactive
