Forged steel valves<\/a> often ignore the problem of grease injection. After the grease gun is refueled, the operator selects the valve and the grease injection method after the low temperature shut-off valve, and then performs the grease filling operation. There are two kinds of conditions for the forged steel gate valve: on the one hand, the amount of grease is less than that of the grease, and the sealing surface is accelerated by the lack of lubricant. On the other hand, excessive fat injection causes waste. There is no accurate calculation of the different valve sealing capacities based on the valve type category. The sealing capacity can be calculated in terms of valve size and type, and a proper amount of grease can be injected reasonably.<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n2, supapele cu poart\u0103 din o\u021bel forjat ignor\u0103 adesea problemele de presiune. \u00cen opera\u021biunea de injectare a gr\u0103simii, sifonul obi\u0219nuit de tip plutitor semi-liber, \u00eenc\u0103rcat cu gr\u0103sime, are o schimbare de la v\u00e2rf la vale. Presiunea este prea sc\u0103zut\u0103, etan\u0219area se scurge sau supapa de siguran\u021b\u0103 e\u0219ueaz\u0103, presiunea este prea mare, produc\u0103torul supapei pentru orificiul de gr\u0103sime este \u00eenfundat, gr\u0103simea de etan\u0219are se \u00eent\u0103re\u0219te sau inelul de etan\u0219are \u0219i bila supapei \u0219i placa supapei sunt blocate. De obicei, atunci c\u00e2nd presiunea gr\u0103simii este prea sc\u0103zut\u0103, gr\u0103simea injectat\u0103 curge \u00een partea inferioar\u0103 a cavit\u0103\u021bii supapei, ceea ce are loc de obicei \u00eentr-o supap\u0103 mic\u0103. Presiunea supapei de reglare a debitului de gr\u0103sime este prea mare. Pe de o parte, robinetul de gr\u0103sime este inspectat \u0219i duza de gr\u0103sime este inspectat\u0103. Dac\u0103 orificiul supapei plutitoare a telecomenzii de gr\u0103sime este blocat, garnitura arcului este \u00eenlocuit\u0103 cu o cheie. Cealalt\u0103 supap\u0103 cu piston este o unsoare. Pentru \u00eent\u0103rire, utiliza\u021bi o solu\u021bie de cur\u0103\u021bare, \u00eenmuia\u021bi \u00een mod repetat gr\u0103simea de etan\u0219are e\u0219uat\u0103 \u0219i injecta\u021bi o nou\u0103 unsoare pentru a o \u00eenlocui. \u00cen plus, tipul de etan\u0219are \u0219i materialul de etan\u0219are afecteaz\u0103 \u0219i presiunea de umplere cu gr\u0103sime. Diferite forme de etan\u0219are au presiuni diferite de umplere cu gr\u0103sime. \u00cen general, presiunea gr\u0103simii de etan\u0219are dur\u0103 este mai mare dec\u00e2t etan\u0219area moale.<\/p>\r\n\r\n\r\n\r\n
Supapele cu glob din o\u021bel forjat acord\u0103 aten\u021bie problemei supapei \u00een pozi\u021bia comutatorului. Supapa cu bil\u0103 este \u00een mod normal \u00een pozi\u021bie deschis\u0103 \u00een timpul \u00eentre\u021binerii \u0219i \u00eentre\u021binerii. \u00cen cazuri speciale, \u00eentre\u021binerea este oprit\u0103. Alte supape nu pot fi discutate din punct de vedere al deschiderii. Supapele de \u00eenchidere din o\u021bel forjat trebuie s\u0103 fie \u00eenchise \u00een timpul \u00eentre\u021binerii pentru a se asigura c\u0103 gr\u0103simea umple canalul de etan\u0219are de-a lungul etan\u0219\u0103rii. Dac\u0103 este deschis, gr\u0103simea de etan\u0219are va c\u0103dea direct \u00een canalul sau cavitatea supapei, provoc\u00e2nd de\u0219euri. C\u00e2nd supapa este uns\u0103, problema injec\u021biei de gr\u0103sime este adesea ignorat\u0103. Presiunea, cantitatea de injec\u021bie de gr\u0103sime \u0219i pozi\u021bia comutatorului sunt normale \u00een timpul opera\u021biunii de umplere cu gr\u0103sime. Cu toate acestea, pentru a asigura efectul de umplere cu gr\u0103sime al supapei, uneori este necesar s\u0103 deschide\u021bi sau s\u0103 \u00eenchide\u021bi supapa pentru a verifica efectul de lubrifiere \u0219i pentru a confirma c\u0103 bila supapei sau suprafa\u021ba supapei este lubrifiat\u0103 uniform.<\/p>","protected":false},"excerpt":{"rendered":"
