6. Sɔhwɛ nhyɛso .
Adwumayɛ nhyɛso yɛ 0.5MPa, na sɔhwɛ nhyɛso no yɛ adwumayɛ nhyɛso no mpɛn 2.0;
Working pressure is>0.5MPa, na sɔhwɛ nhyɛso no yɛ adwuma nhyɛso a ɛka ho 0.5MPa.
7. Sɔhwɛ kwan .
7.1 Pre-Test stage: Ma nsuo nhyɛsoɔ a ɛwɔ paipu no mu no so nkakrankakra kɔ sɔhwɛ nhyɛsoɔ no mu ma 30min. Wɔ bere no mu no, hyɛ nhyɛso no ma, nanso ɛnsɛ sɛ ɛboro sɔhwɛ nhyɛso no so; Hwɛ sɛ nsuo no retu na asɛe wɔ paipu no ntam ne nea wɔde hyɛ mu no ho; Sɛ nsuo no twetwe na ɛsɛe a, gyae nhyɛsoɔ sɔhwɛ no wɔ berɛ mu na kyerɛ nea enti a ɛte saa na fa nneɛma a ɛne no hyia no yɛ adwuma.
7.2 Nsɔhwɛ gyinabea titiriw: Sɛ wogyae nsuo a wɔde gu mu ne nhyɛsoɔ akyi a, ɛma ɛyɛ den ma 15min; Sɛ nhyɛsoɔ a ɛkɔ fam wɔ 15min akyi no ntra 0.03MPa a, sɔhwɛ nhyɛsoɔ no so tew kɔ adwumayɛ nhyɛsoɔ mu ma 30min. Sɛ nsu a ɛretu no nni hɔ a, hydraulic sɔhwɛ no fata.
