Secondly, the equipment base lacks the limit in the XY direction: equipment during operation, because the interdynamic of power, self also can the effect influence of atress, nevertheless equipment itself does not have spacing in XY direction to with adjust between the parallels contact surface less, generally only be provided with under 4 corner faces and adjust the parallels, adjust the parallels and also do not have fixedly with ground, under this condition, the influence of equipment atress very easily produces the displacement of non-direction of height.
Thirdly, the equipment base is stressed unevenly and deforms greatly: the adjusting sizing blocks are arranged below the equipment base and are generally positioned at two sides of the foundation bolt, if the adjusting sizing blocks are far away from the foundation bolt, when the foundation bolt is screwed down, the base is stressed like a double-support beam bearing concentrated load, and overlarge additional bending stress is generated; if the sizing block is too close to the ground bolt, the casting and vibrating space is insufficient during secondary grouting, and the concrete strength is affected.
And fourthly, the common oblique sizing block is made of common carbon steel generally, and the flat sizing block is made of common carbon steel or cast iron, so that the strength and the hardness are low, the deformation is easy, and the adjustment precision is poor.
