      小编介绍了燃气锅炉的分类和液压机的精度。
      The classification of gas-fired boilers and the accuracy of hydraulic presses are introduced.
      燃气锅炉按用途分类
      Gas fired boilers are classified by use
      1.工业燃气蒸汽锅炉:用于工业生产和供热。 大多数是燃烧和热效率低的低参数,小容量锅炉。
      Industrial gas steam boilers: for industrial production and heating. Most of them are low-parameter, small-capacity boilers with low combustion and thermal efficiency.
      2.电站锅炉:主要用于发电。 大多数是高参数,大容量锅炉,燃烧室燃烧效率高。
      2. Power plant boilers: mainly used for power generation. Most of them are high-parameter, large-capacity boilers with high combustion efficiency.
      3.船舶锅炉:用于船舶动力。 这种锅炉一般为中低参数,燃料为燃料,要求体积小,重量轻,移动方便。
      3. Marine Boiler: Used for Marine Power. This kind of boiler is generally of medium and low parameters, and the fuel is fuel. It requires small size, light weight and convenient movement.
      4.机车锅炉:主要用途是机车动力。 总体参数低,属于小容量锅炉,燃烧床燃烧,要求结构紧凑且可移动。
      4. Locomotive Boiler: The main use is locomotive power. The overall parameters are low, belonging to small capacity boilers, burning bed combustion, requires compact and movable structure.
      2.燃气蒸汽锅炉根据工作流体的类型和输出状态进行分类,可以分为:
      2. Gas-fired steam boilers are classified according to the type of workflow and output state, which can be divided into:
      1.蒸汽锅炉:出口的工作流体是蒸汽。
      1. Steam Boiler: Steam is the working fluid for export.
      2.热水锅炉:出口工作介质为热水。
      2. Hot water boiler: the outlet medium is hot water.
      3.特殊工作锅炉:出口是特殊工作流体,例如某些有机物。
      3. Special Working Boiler: The outlet is a special working fluid, such as some organic matter.
      三台燃气蒸汽锅炉可分为:根据出口工作压力:
      Three gas-fired steam boilers can be divided into: according to the outlet working pressure:
      1.超高压锅炉:出口蒸汽压力为14MPA(140kgf / cm)。
      1. Ultra-high pressure boiler: outlet steam pressure is 14 MPA (140 kgf/cm).
      2.高压锅炉:出口蒸汽压力为10MPA(100kgf / cm)。
    山东燃气锅炉
      2. High pressure boiler: outlet steam pressure is 10MPA (100kgf/cm).
      3.二次中压锅炉:出口工作压力为2.5MPa。
      3. Secondary medium pressure boiler: outlet working pressure is 2.5 MPa.
      4.中压锅炉:出口蒸汽压力为3.9 MPa(39 kgf / cm)。
      4. Medium pressure boiler: outlet steam pressure is 3.9 MPa (39 kgf/cm).
      5.超临界压力锅炉:出口蒸汽压力约为25 MPa(约250 kgf / cm)。
      5. Supercritical pressure boiler: outlet steam pressure is about 25 MPa (about 250 kgf/cm).
      6.亚临界锅炉:出口蒸汽压力为17 MPa(170 kgf / cm?)。
      6. Subcritical Boiler: The outlet steam pressure is 17 MPa (170 kgf/cm?).
      7.低压锅炉:出口工作压力(表压)小于或等于1.3MPa(13kgf / cm)。
      7. Low pressure boilers: the outlet working pressure (gauge pressure) is less than or equal to 1.3 MPa (13 kgf/cm).
      液压机的精度决定了零件的精度。 然而,仅使用静态精度来测量印刷机的精度不是非常精确。 这是因为压力机本身的机械强度对冲压精度有很大的影响。 如果压力机本身的强度低,则在达到冲压压力时,压力机将变形。 因此,即使在静态条件下很好地调节了上述条件,床的变形也可能由于强度的影响而引起。 发生了差异。 可以看出,压力机的精度与强度有很大的关系,强度对冲压工作有很大的影响。 因此,在高精度工件的冲压生产和强连续性中,必须选择精度。 更高,更刚性的压力机。
      The accuracy of hydraulic press determines the accuracy of parts. However, it is not very accurate to measure the accuracy of a printing press only by using static accuracy. This is because the mechanical strength of the press itself has a great impact on stamping accuracy. If the strength of the press itself is low, the press will deform when the stamping pressure is reached. Therefore, even if the above conditions are well adjusted under static conditions, the deformation of the bed may be caused by the influence of strength. Differences have taken place. It can be seen that the accuracy of the press has a great relationship with its strength, which has a great influence on the stamping work. Therefore, in the stamping production and strong continuity of high precision workpiece, precision must be chosen. A higher, more rigid press.
