Wood dryer
1. Foundation acceptance, mainly check the foundation concrete pouring quality and size position deviation. Its appearance requires that the foundation surface is clean, free of oil stains, dust, debris, no exposed steel bars, no crack angles, and no casting defects such as residual shell plates in the expected holes. The deviation of the size and position of the foundation should meet the following requirements: For the shape, size and position of the basic coordinates, the error of the vertical axis and the horizontal axis is less than 20 mm. The elevation error of different planes is less than 20 mm, only Xu and Negative are not allowed to be positive, the total length of slope error is less than 20 mm, whether the discharge end is allowed to be positive, the unevenness of the upper plane is less than 5m, and the total length is less than 10 mm.
2. Wood drying equipment inspection, packaging wood drying equipment, parts, components, standard parts, inventory and other random documents supplied by the anti-skid control device, sent to the wrong check for missing parts, deformation and damage, etc., and used for good records, so install Before that, purchase or prepare. When packaging transparent protective coatings and coatings of dust, grease, rust spots, etc., as well as handling, caused damage during transportation, the received dressing is deformed. The key fitting part is pre-detected and pre-arranged to avoid rework of the installation work and ensure the progress of the installation quality of the installation.
three. Prepare the installation process, including basic installation procedures, basic installation procedures, installation process methods, and safety technical requirements. Then set the bottom plate, determine the reasonable layout of the bottom plate, and pay attention to the bottom plate should be as close as possible to the anchor rod, placed at the center of gravity of the load, to prevent uneven load on the bottom plate. The number of base plates in each group shall not exceed 5 pieces. Thicker pads should be placed up and down, thinner pads should be placed in the middle, and stacked pads should be in good contact. When the adjustments cannot overlap completely, the contact area should be greater than 80%. The bottom plate and the foundation should have sufficient contact accuracy so that the foundation is tightly contacted, placed stably, and there is no hollow angle sloshing phenomenon, ensuring that the bottom plate is tilted up and down the same as the foundation in the longitudinal direction; it should be basically horizontal in the horizontal direction. The baseline marking adopts the optical theodolite, laser collimator or the wire drawing method with poor precision to horizontally level and align the roller base, and repeat the vertical alignment several times until the coordinate position, horizontal horizontal and vertical inclination angle meet the requirements.
