Kutseka chizindikiro chakunja - Mfundo zazikulu zodzipatula mphamvu

Mlandu wa Ngozi 1
Pamene wantchito wa kontrakitala anali kuphwanya chitoliro chomwe chinali pansi pa payipi yozimitsira moto ya manifold 1 ball valve (pali mphamvu yokwera pamwamba pa valavu ya mpira), thupi la valavu ya mpira linasweka mwangozi. Mpira wachitsulo womwe unali mkati mwa valavu unatulutsidwa ndi madzi a moto ndipo unagunda wantchitoyo kumaso. Mwamwayi, wantchitoyo anali atavala magalasi otetezera panthawiyo ndipo sanavulale kwambiri.
Kodi chifukwa chachikulu cha ngoziyi chinali chiyani?

Mlandu wa Ngozi 2
Pamene wantchito wa kontrakitala ankatenga zitsanzo za mafuta odzola kuchokera ku compressor ya mpweya ali mu mkhalidwe woyimirira, mphamvu ya makina oponderezedwa a mpweya inatsika chifukwa cha kugwiritsa ntchito kwambiri madzi obowola mu mwendo wa pulatifomu pa malo obowolera, ndipo compressor ya mpweya inayamba mwadzidzidzi, zomwe zinayambitsa mphamvu mu makina odzola mafuta, ndipo dzanja la wantchitoyo linapsa ndi mafuta odzola otentha kwambiri omwe anatuluka.

Mfundo zazikulu zodzipatula mphamvu
Kutha kuzindikira ntchito zomwe zimafuna kudzipatula kwa mphamvu:
Chilolezo chogwira ntchito chiyenera kuperekedwa pa ntchito zonse zomwe si zachizolowezi;
Wopereka chilolezo chogwirira ntchito ndi woyang'anira katundu alankhulana mokwanira za ntchito yomwe ikufunidwa;
Wopereka layisensi ndi woyang'anira zodzipatula amadziwa bwino zida ndi njira zomwe zimagwiritsidwa ntchito pamalopo.

Mfundo zazikulu zodzipatula mphamvu 2
Njira ndi cholinga cha kudzipatula kwa mphamvu ndi zolondola:
Kudzipatula kumachitika kokha ndi ophunzitsidwa mwapadera, opambana mayeso, ndi "odzipatula" ovomerezeka;
Pambuyo poti kaye yatha, tsimikizirani chinthu chomwe chaikidwa kuti muwonetsetse kuti kaye yaikidwa bwino;
