Pesticide plant waste gas treatment equipment

In the process of equipment installation, the center line, level and elevation deviation adjustment respectively called alignment, leveling, and elevation, this is the three elements of the installation must fine.

A, looking for positive. To find is the center line of the equipment installation, mechanical main shaft and the bearing hole on the basis of a polished surface can be take as the centerline.

Second, the leveling. Adjust the levelness of the mechanical equipment is installed, its importance is greater than the alignment. Flash is relative to the horizontal plane tilt will directly affect the stability and balance of the center of gravity of equipment. And, with a rotary movement of the machine, because of the tilt, will inevitably produce the vibration caused by inertial force. Tilt will worsen the lubrication conditions, as well as excessive wear due to additional load equipment, reduce work quality, and the fl and accuracy. Leveling purpose is to maintain the stability of the installation, reduce vibration, avoid deformation, in order to guarantee the working accuracy and prevent + reasonable wear and tear. Therefore, must achieve the levelness of the equipment requirements, parallelism and perpendicularity, the installation process according to the equipment manual or the ministry of machine building equipment installation acceptance specification required.

(1) the position of the leveling datum. General with sliding parts guide surface (such as machine tool guideway) or assembling components surface, job card bearing surface and countertops for leveling datum.

(2) installation shim selection should be 15 and equipment according to the instructions of the provisions of the relevant technical documents. Mat iron role is to make the equipment installed in the base has a relatively stable bearing and a uniform load distribution, and in accordance with the installation of shim adjustment equipment level and assembly precision. Therefore, shim form, size, quantity, and installation site selection is very important.

(1) of the specifications of the anchor bolt, nut and washer should comply with the specifications and design requirements, according to the selected JB15-1959. Vibration of the larger equipment should add lock nut. The long guide rail machine spherical washer should be adopted.

Third, find elevation. Elevation is install benchmark to the height of the measured surface (or lines). Large equipment installed, will gradually subsidence in operation process. New equipment is running a phase should be tested periodically after the change of observation point elevation. So, if necessary, the equipment must be to collapse, to be installed. Find elevation is to make the mechanical equipment of a datum (line) at the height of the specified. General direct measurement on time to the elevation measurement equipment surface (line) for inspection.
