防爆风机的安装找正作业,根据各种防爆风机不同的精度要求、驱动方式、转速、功率等,在其内容和程度上有不同的要求。因此,根据防爆风机的不同要求进行安装与找正是很重要的事项。

The installation of the explosion-proof fan is to find the correct operation. According to the different precision requirements, driving mode, speed and power of various explosion-proof fans, there are different requirements in its content and degree. Therefore, installation and correction are very important according to the different requirements of the explosion-proof blower.

1)清扫基础混凝土表面,检查其水平度,如不合规定,可以铲平不平的部分。

1) clean up the surface of the foundation concrete and check its level. If it is unqualified, it will be able to smooth out the uneven parts.

2)将防爆风机底座放到基础上,在墓础面与底座面之间插人垫铁,其间晾仅需保证灰浆流人即可。用该垫铁调整水平度,使防爆风机底座处于绝对水平状态。

2) put the base of the explosion-proof fan on the foundation, and insert the mat iron between the base of the tomb and the base surface. Using the pad iron to adjust the level, the base of the explosion proof fan is at an absolute level.

3)安装一般防爆风机时,亦可准备厚度不同的数种矩形垫铁(钢板),以数块重迭进行调整,采用联轴器传动的防爆风机可利用联轴器进行检查,调整水平后,再焊接固定。

3) when installing the general explosion-proof fan, we can also prepare several kinds of rectangular padding iron (steel plate) with different thickness. It can be adjusted by several blocks. The flameproof fan which is driven by the coupling can be checked with a coupling. After adjusting the level, it can be rewelded and fixed.

垫铁插进地脚螺栓的两侧,在调整水平的过程中,也有同时采用调整螺栓进行调整的。

Inserting iron into both sides of the anchor bolt is also adjusted by adjusting bolts at the same time in adjusting the level.

4)地脚螺栓穿过底座的地脚螺栓孔应垂直于地脚螺栓用方孔内。

4) the anchor bolt of the anchor bolt across the base should be perpendicular to the square hole of the anchor bolt.

5)地脚螺栓用孔及底座与地基混凝土之间的间隙内,须灌人足够的灰浆,以保证混凝土结构件的强度。

5) in the gap between the hole and the foundation of the anchor bolt, enough mortar should be filled to ensure the strength of the concrete structure.

安装重要或精度要求较高的防爆风机时,应先把灰浆灌人埋设地脚螺栓的孔内,待其充分硬化后,重新找正、调整为水平,在达到安装精度要求后,再将灰浆灌人底座与地基棍凝土之间的间隙。

When installing important or high precision explosion-proof blower, the grout should be poured into the hole of the anchor bolt in the hole first. After it is fully hardened, it should be re searched and adjusted to the level. After the installation accuracy is reached, the gap between the mortar and the foundation of the foundation is then filled.

6)等到灰浆充分硬化后,紧固地脚螺栓的螺母。

6) until the mortar is sufficiently hardened, fasten the nut of the anchor bolt.

7)灌浆工序对于在整个防爆风机安装过程相当重要。它不仅对底座与地基混凝土间的空间起作用,而且对防爆风机负载的传递、机械刚度的辅助也有较大影响。故在施工时,应特别注意泥浆的收缩性和断裂性,采取合理的施工方法。

7) grouting process is very important for the whole installation process of explosion proof blower. It not only plays a role in the space between the foundation and the foundation concrete, but also has great influence on the transmission of the explosion-proof fan load and the auxiliary stiffness of the machine. Therefore, during construction, special attention should be paid to shrinkage and fracture of the mud, and reasonable construction method should be adopted.

8)一般的大型防爆风机,机壳与底座是分开的。对于剖分式防爆风机,其机壳是分为几部分的。安装时,首先按照上述方法安装好防爆风机底座和轴承底座后,再按照下机壳、转子、上机壳的顺序.边调整定子与转子图3-la所示。

8) the general large explosion-proof fan is separated from the chassis. For split explosion-proof fan, its chassis is divided into several parts. When installing, first installs the blower base and bearing base according to the above method, and then according to the order of the lower shell, the rotor and the upper shell. The edge adjusts the stator and the rotor diagram 3-la.

重要的防爆风机安装时,因其对水平度的要求较高,应使用上下两块为一组的斜垫铁进行调节。

When the important explosion-proof fan is installed, the upper and lower two blocks should be adjusted as a group of oblique pad iron because of its higher level requirement.

组装前,应先检查各研合面是否有毛刺、卷边、变形等问题。组装时,应注意保持研合面的清洁及防止碰伤研合面。在组装上机壳时,即不能使机壳碰到转子上,也不得在转子上附加载荷。

Before assembling, check whether there are burrs, curling, deformation and so on. During assembly, attention should be paid to keeping the surface clean and preventing the surface of the joint. When assembling the case, the shell can not be touched on the rotor nor attached to the rotor.

9)有些情况下,因无法设置足够的地基,常常将防爆风机安装在减振器上,以减轻振动的传递力,减振器应以防爆风机的重心为中心进行布置,保证各减振器的压缩量一致。

9) in some cases, the explosion-proof fan is often installed on the shock absorber in order to reduce the transfer force of vibration because of the inability to set up enough foundation. The shock absorber should be arranged with the center of gravity of the explosion blower as the center to ensure the uniform compression of the shock absorbers.

采用此种安装方式虽能减少振动对地基的传播,但防爆风机本身的振动却会增加,故防爆风机进出口连接管路时,须采用帆布或橡胶挠性接头。

Although this installation can reduce the transmission of the vibration to the foundation, the vibration of the explosion blower itself will increase, so the flexible joints of canvas or rubber must be used when the explosion-proof fan is connected to the inlet and outlet of the pipe.

10)在建筑物内,有时也采用天栩悬挂等型式安装防爆风机。除极小型的防爆风机可以采用吊挂螺栓式框架来安装外,应尽量采用焊接框架组合天棚式基础。

10) installing explosion-proof fans in buildings and sometimes using ceiling mounted suspension. Except for very small explosion-proof fans which can be installed by hanging bolt frame, the welded frame combined ceiling type should be used as far as possible.
