1. Vim li cas Mini DC Diaphragm Twj Tso Kua Mis Thiaj Tseem Ceeb Rau Mars Rovers

Cov Kev Cai Tseem Ceeb rau Martian Sampling Systems

• Kev Ruaj Ntseg Ib puag ncig hnyav heevKub ntawm -125°C txog +20°C, plua plav uas kis tau thoob plaws, thiab qhov siab ntawm huab cua ze ntawm lub tshuab nqus tsev (0.6 kPa).

• Kev Tswj Xyuas Cov Kua Dej Uas Muaj Kev Ntsuas ZooKev siv cov abrasive regolith (av Mars), cov organic compounds uas yaj tau, thiab kev kuaj pom cov kua dej ntsev.

• Kev Siv Hluav Taws Xob TsawgCov tshuab siv hluav taws xob hnub ci xav tau cov khoom siv uas txuag hluav taws xob (<5W).

Cov twj tso kua mis Mini DC diaphragm daws cov teeb meem no los ntawm:

• Kev Ua Haujlwm Tsis Muaj RojTshem tawm cov kev pheej hmoo ntawm kev ua qias tuaj rau kev sau cov qauv huv si.

• Tsim Qauv Me Me: Haum rau hauv cov kev txwv ntawm kev thauj khoom nruj (piv txwv li, Perseverance's Sampling thiab Caching System).

• Kev Sib Txuas Lus DC Tsav TshebUa haujlwm tau zoo ntawm cov tshuab fais fab rover (12–24V DC).

2. Cov Ntawv Thov Hauv Cov Khoom Siv Geological Sampling

A. Kev Sau thiab Lim Plua Plav ntawm Regolith

• Kev Txais Cov Qauv: Cov twj tso kua mis me metsim kom muaj kev nqus dej kom rub regolith mus rau hauv cov chav sau khoom.

• Cov Txheej Txheem Tiv Thaiv Pluav: Cov tshuab lim dej ntau theem, uas siv lub twj tso kua mis, tiv thaiv cov khoom sib txhuam kom tsis txhob ua puas rau cov cuab yeej rhiab heev.

Kev Kawm Txog Cov Ntaub NtawvNASA lub Perseverance rover siv lub tshuab diaphragm-based pump los lim thiab khaws cov qauv av hauv cov raj huv heev.

B. Kev Tshuaj Xyuas Roj thiab Kua

• Kev Siv Roj Chromatography: Cov twj tso kua mis thauj cov pa roj Martian mus rau cov spectrometers rau kev tshuaj xyuas cov khoom sib xyaw.

• Kev Tshawb Pom Cov Dej Ntshav Hauv AvCov twj tso kua dej qis pab rho tawm thiab ua kom cov qauv kua ruaj khov rau kev kuaj tshuaj lom neeg.

C. Kev Khaws Cov Qauv

• Kev Siv Lub Tshuab Nqus Tsev: Cov twj tso kua mis diaphragm Mini DC tsim cov tshuab nqus tsev ib nrab hauv cov raj xa dej kom tiv thaiv kev puas tsuaj thaum lub sijhawm khaws cia thiab thaum kawg av rov qab los.

3. Kev Cov Teeb Meem Txog Kev Siv Tshuab thiab Kev Dais Teeb Meem Txog Kev Tsim Kho

Kev Tsim Kho Tshiab ntawm Cov Khoom Siv

• PTFE-Coated Diaphragms: Tiv taus cov tshuaj xeb los ntawm perchlorates hauv av Martian.

• Cov Tsev Stainless HlauTiv taus cov hmoov av abrasive thaum tseem tswj tau qhov ruaj khov ntawm cov qauv.

• Kev Tswj Xyuas KubCov ntaub ntawv hloov pauv theem thiab cov rwb thaiv tsev airgel ua rau qhov kub ntawm lub twj tso kua mis ruaj khov thaum muaj kev hloov pauv ntau heev.

Kev Txhim Kho Fais Fab

• PWM (Pulse Width Modulation) Kev Tswj: Kho qhov ceev ntawm lub twj tso kua mis raws li qhov xav tau tiag tiag, txo kev siv hluav taws xob los ntawm 30%.

• Kev Sib Txuas Lus Hnub Ci: Ua haujlwm feem ntau thaum lub hnub ci ntsa iab tshaj plaws kom txuag tau lub zog roj teeb.

Kev Tiv Thaiv Kev Co thiab Kev Poob Siab

• Cov Txheej Txheem Mounting Uas Muaj Kev Tiv ThaivCais cov twj tso kua mis ntawm kev txav mus los thiab kev co ntawm qhov drilling.

• Cov Seal Rov QabTiv thaiv kom tsis txhob muaj qhov xau thaum lub sijhawm tso tawm high-G thiab kev hla thaj chaw Martian.
