Mfundo Yoyambira
Kupopa ntchito kwa mndandanda wa JRP Mizu idachitika kudzera m'ma rotor awiri owoneka ngati '8' m'chipinda chopopera chozungulira mozungulira mozungulira. Ndi chiŵerengero cha 1: 1, ma rotor awiri amadzisindikiza okha popanda kugwedezana ndi chipinda. Mipata pakati pa zigawo zosunthika ndi yopapatiza mokwanira kuti isindikize kumbali ya utsi ndi mbali yolowera mumayendedwe a visous ndi kutuluka kwa maselo, kuti akwaniritse cholinga chopopera mpweya m'chipindamo.
Ma rotor akapeza 1 ndi 2 mchipindacho, kuchuluka kwa mpweya wolowera kumawonjezeka. Pamene ma rotor apeza 3 m'chipinda, gawo la mpweya lidzatsekedwa kuchokera ku mpweya wolowera. Ma rotor akapeza pa 4, voliyumu iyi imatsegulidwa kuti ituluke. Pamene ma rotors apitirira, mpweya umatuluka kudzera mumlengalenga. Ma rotor amatha kuzungulira mizere yopitilira iwiri kamodzi kamodzi kazungulira.
Kusiyana kwamphamvu pakati pa mbali yolowera ndi potuluka ya pampu ya mizu ndikochepa. JRP mndandanda mizu mpope utenga valavu bypass. Pamene mtengo wa kupanikizika kwapakati ufika pa chiwerengero china, valavu yodutsa imatsegula zokha.Voliyumu ina ya mpweya kuchokera kumbali yotulukira imayenda kupita ku mbali yolowera kumbali yolowera kudzera mu valve yodutsa ndi njira yobwerera, yomwe imachepetsa ntchito ya pampu ya mizu ndi mpope wakutsogolo kwambiri mu chikhalidwe cha kusiyana kwakukulu. Pakalipano, chifukwa cha ntchito yotsitsa pamene valavu yodutsa imatsegulidwa, imaonetsetsa kuti pampu ya JRP ya vacuum ndi mpope wakutsogolo zimayambira nthawi imodzi kuti apewe kulemetsa kwa onse awiri.
Pampu ya mizu iyenera kugwiritsidwa ntchito ngati pampu limodzi ndi mpope wakutsogolo (monga pampu yozungulira, pampu yamavavu ndi pampu ya mphete yamadzimadzi). Ngati pakufunika kuti afikire digiri yapamwamba ya vacuum, ma seti awiri a mapampu a mizu amatha kulumikizidwa kuti agwire ntchito ngati gawo limodzi la magawo atatu a mpope.

Makhalidwe
1. Pali kukangana kwa zero pakati pa ma rotor, komanso pakati pa rotor ndi chipinda chopopera, kotero palibe chifukwa cha mafuta odzola. Chifukwa chake, pampu yathu imatha kupewa kuipitsidwa kwamafuta pa vacuum system.
2. Kapangidwe kakang'ono, komanso kosavuta kukhazikitsa mopingasa kapena molunjika.
3. Kuyenda bwino kwamphamvu, kuthamanga kosasunthika, kugwedezeka pang'ono komanso phokoso lochepa.
4. Imatha kupopa mpweya wosasunthika.
5. Mwamsanga anayamba ndipo akhoza kukwaniritsa kukakamizidwa kwambiri mu nthawi yochepa.
6. Mphamvu yaing'ono ndi yotsika mtengo yokonza ntchito.
7. Mtengo wodutsa pamizu pampu ukhoza kusangalala ndi chitetezo chokwanira, kuti ntchitoyo ikhale yotetezeka komanso yodalirika.

Masanjidwe a Ntchito
1. kuyanika vacuum ndi impregnation
2. vacuum degass
3. vacuum pre-kutulutsa
4. kutopa kwa gasi
5. Njira zopangira vacuum distillation, vacuum concentration ndi vacuum kuyanika mumakampani opanga mankhwala, mankhwala, chakudya ndi zakumwa, mafakitale opepuka komanso mafakitale opanga nsalu.
