Mechanical seal material calculation parameters
First, the density
1,2 Cr13, 1Cr18Ni9Ti, 1Cr18Ni12Mo2Ti Density 7.9kg / cm³ 2. YG6, YG8, YN6, YN8 Density 14.9kg / cm³ 3. Silicon carbide density 3.2kg / cm³ 4. Polytetrafluoroethylene 2.2kg / cm³ 2. Weight calculation Unit: kg, mm)
1, Yuan steel weight calculation coefficient: diameter 2 × 0.0000062 × length
2, stainless steel ring forging weight calculation factor: (diameter 2 - diameter 2) × 0.000006758 × length (including 7% of the fire)
3, the alloy ring weight calculation coefficient: (diameter 2 - diameter 2) × 0.0000117024 × length
Third, the standard machining allowance
1, when the product diameter smaller, thicker or longer wall thickness is not suitable for forging processing using direct processing yuan, the margin selected by the following principles:
(1) The product diameter ≤60mm, length ≤120mm: yuan steel outer diameter = product diameter + 1mm and then selected from the standard diameter of steel; such as product diameter Φ45 ~ Φ49mm select Φ50mm yuan steel. Blank length size = product length +4 ~ 5mm.
(2) 60mm <product diameter ≤ 100mm, length ≤ 200mm: element steel outer diameter = product diameter + 1.5mm and then select from the standard steel diameter; blank length size = product length +5 ~ 6mm.
(3) 100mm <product diameter ≤200mm, length ≤400mm: elemental outer diameter = product diameter +2 ~ 3mm and then selected from the standard diameter of steel; blank length size = product length +6 ~ 8mm.
2, when the product requires forging or casting process due to process requirements, the margin should be selected according to the following principles:
(1) The diameter of the product ≤80mm: The diameter of the blank = size of the product + (-) 5mm (Note: the inner diameter adopts "-" the same below);
(3) 80mm <product diameter size ≤100mm: blank diameter size = product size + (-) 6mm; blank length size = product length + 6mm.
(4) 100mm <product diameter size ≤130mm: blank diameter size = product size + (-) 7mm; blank length size = product length + 6mm.
(5) 130mm <product diameter size ≤ 160mm: blank diameter size = product size + (-) 8mm; blank length size = product length + 6mm.
(6) 160mm <product diameter size ≤200mm: blank diameter size = product size + (-) 10mm; blank length size = product length +7mm.
(7) 200mm <product diameter size ≤ 280mm: blank diameter size = product size + (-) 12mm; blank length size = product length + 9mm.
(8) 280mm <product diameter size ≤400mm: blank diameter size = product size + (-) 15mm; blank length size = product length +12mm.
Attached: 1Cr18Ni12Mo2Ti inner diameter ≤ 40mm, 1Cr18Ni9Ti inner diameter ≤ 45mm, outer diameter ≤ 100mm 2Cr13 In principle, the use of direct processing yuan.
Fourth, material loss
1, forging fire consumption 7%; all plate cutting round calculation, cut the ring calculation board (such as cutting Φ200 × Φ100 ring count 200 × 200 plate).
Ground Rail Series
The ground rail is a cast beam platform designed and spliced according to the fixed points of equipment, which is mainly used for the assembly, test, welding and inspection of large equipment. The ground rail can also be called T-channel ground rail, ground beam, ground channel iron, foundation channel iron, cast iron ground rail and strip platform. The ground rail produced by our company is made of high strength cast iron HT200-300, and the hardness of the working face is HB170-240. After two times of manual treatment (manual annealing of 600-700 degrees or natural aging of 2-3 years), the precision of the product is stable and the performance is good.
The main models of ground rails produced by our company are as follows:
