Qhov kawg Qhia rau Reciprocating Compressor Capacity Control Methods

Reciprocating compressorsyog tsim los rau kev ua haujlwm siab tshaj plaws ntawm qhov siab tshaj plaws, tab sis kev ua haujlwm tiag tiag xav tau kev hloov pauv hloov pauv kom haum rau cov txheej txheem kev xav tau. Ntawm Xuzhou Huayan Gas Equipment, peb tshwj xeeb hauv kev tsim cov peev txheej tswj kev daws teeb meem uas ua kom zoo tshaj plaws hauv kev siv ntau yam kev lag luam.

1. Txoj Cai Ceev (Variable Speed ​​Drive)

Lub hauv paus ntsiab lus: Kho compressor RPM kom sib txawv roj ntws.
Qhov zoo:

• Nruam, linear ntws tswj los ntawm 40% mus rau 100% muaj peev xwm
• Kev txuag hluav taws xob ze ze ntawm kev txo qis
• Tuav lub siab sib piv nyob rau theem 18
  Kev txwv:
• Tus nqi siab VSD tshuab rau cov motors loj (> 500 kW)
• Cov teeb meem lubrication thiab valve flutter hauv qab 40% RPM
• Nce bearing / crankshaft hnav ntawm huab ceev 46
  Qhov zoo tshaj plaws rau: Turbine-tsav units lossis nruab nrab-qhov loj me compressors nrog kev hloov pauv tsis tu ncua.

2. Bypass Control

Lub hauv paus ntsiab lus: Recirculates tso pa roj rau suction ntawm li qub.
Qhov zoo:

• Yooj yim installation nrog tus nqi qis ua ntej
• Tag nrho 0-100% kev hloov pauv muaj peev xwm
• Cov lus teb ceev ceev rau kev tiv thaiv surge 48
  Zog Txim:
• Khib 100% ntawm compression zog ntawm recirculated roj
• Ua kom kub qhov nqus los ntawm 8-15 ° C, txo kev ua haujlwm
• Unsustainable rau kev ua haujlwm tas mus li 16

3. Kev kho lub hnab tshos Clearance

Lub hauv paus ntsiab lus: nthuav cov ntim tuag hauv lub tog raj kheej kom txo tau qhov ua tau zoo ntawm qhov ntim.
Qhov zoo:

• Lub zog noj scales linearly nrog cov zis
• Mechanical simplicity nyob rau hauv tas li ntim designs
• Zoo tagnrho rau khov kho-xeev 80-100% muaj peev xwm trimming 110
  Qhov tsis zoo:
• Tsawg turndown ntau yam (<80% drastically poob efficiency)
• Slow teb (20-60 vib nas this rau siab stabilization)
• Kev saib xyuas siab rau piston-sealed variable hnab ris 86

4. Valve Unloaders

ib. Full-Stroke Unloading

• Muaj nuj nqi: Tuav lub valve qhib thoob plaws hauv compression
• Cov kauj ruam tso zis: 0%, 50% (ob lub tog raj kheej ua haujlwm), lossis 100%
• Kev txwv: kev tswj nruj nkaus xwb; ua rau valve qaug zog 68

b. Ib nrab-Stroke Unloading (PSU)
Revolutionary Efficiency:

• Delays lub valve kaw thaum lub sij hawm compression
• Ua tiav 10-100% kev hloov pauv tsis tu ncua
• Txuag 25-40% zog vs. bypass los ntawm compressing tsuas xav tau roj 59
  Technical Superiority:
• Millisecond teb ntawm electro-hydraulic actuators
• Tsis muaj kev txwv ceev (txog 1,200 RPM)
• Tau tshaj txhua yam uas tsis yog-reactive gases
