Mechanical seal material weight calculation
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). Construction Hoist Steel Structure
Construction Hoist Steel Structure means the construction hoist spare parts like Construction Hoist Mast Section, Passenger Hoist Cage, Construction Hoist Wall Tie and so on.
The length of each mast section is 1508mm, the rack is fixed on the mast by three bolts and it can be exchanged. For the single cage hoist there is only one rack on the mast section, and the mast section can be used for the double cages hoist by increasing one rack. The section of the mast is diverse, select one type section according to different hoist. The mast sections are bolted together with M24 bolts and nuts to form mast. The mast is tied to the building with tie-in and is the guide rail of the cage. According to the user`s or circumstance`s request, surface of mast is hot dip galvanized, which can prevent it rusting.
The tie-in(wall tie) is the linked part between mast and building, to keep the stabilization of the mast. Distance between the tie-in is about 6~9m alone the mast. There are several types of tie-in. Select one of them according to need, tie-in can adjust the vertical of mast in definite ranges. According to the user`s or circumstance`s request, surface of the tie-in is hot dip galvanized, which can prevent it rusting.
The cage dimension(L×W×H)(m): 3×1.5×2.5. We can also manufacture cages of other size according to the user`s needs. The material of the cage and the door material can be steel wire weave, aluminum-plastic panel, punched-plate, figured aluminum board or other type according to user`s needs. The gate is equipped with drawing gate,include small turn over gate.
