The effect of the fixed bracket is inseparable during the installation. The success of the fixed bracket device is directly related to the normal operation of the flange elastic device. The flange elastic device can alleviate the blind plate thrust in the pipeline operation during the operation of the equipment, but At the exit of the pump and at the corner of the pipeline, the power transmission joint and the limit force transmission joint should be selected in the sliding pipeline connection without fixed buttresses, infinite buttresses and directional limit buttress brackets to prevent the thrust from being concentrated in the corners of the pipe At the proximal end of the pump or the pump, an impact can damage the device. Look at the forces and settings of the buried guide bracket.
When installing the device, pay attention to the setting and force of the fixing bracket, and do not pull out the elastic end of the elastic device due to cracking of the fixing bracket during cracking.
Some planning devices must be planned, otherwise the pipeline is prone to problems.
Pay attention to the setting interval of the guide bracket. The first guide bracket should be installed at a distance of 4D (4 times) from the compensator. The second guide bracket should be installed at a distance of 14D from the compensator.
The thrust of the blind plate when starting the pump can be transmitted to various parts of the pump and the pipeline through the force-transmitting bolts. The elastic joint, the force-transmitting joint, the elastic device and the rubber joint, the clamp flexible joint and the quick joint are all included in the pipeline connection. Effect, play an elastic compensation displacement effect on the operation of the pipeline.
In fact, in various pipeline applications, the flange elastic device is used to maintain the pipeline to a certain extent, which provides great convenience for the installation and maintenance of the pipeline. The axial compensator force bracket is divided into a primary fixed bracket, a secondary fixed bracket, and a guide bracket.
The horizontal thrust of the main fixed bracket is huge, and the large pipe diameter can reach hundreds of tons. The civil construction is difficult to settle, and a comprehensive structural calculation is required, which is attributed to the heavy-duty bracket. The secondary fixed bracket has the same force as the main fixed bracket, but the internal pressure thrust is balanced to offset, and the total thrust is small. It is not an order of magnitude compared with the main fixed bracket, and is attributed to the intermediate load reduction bracket.
When calculating the fixed point thrust, the forces on each side of the fixed point should be calculated separately and then combined. The directions on both sides of the fixed point are together, and the vector sum of the two forces is used as the fixed point thrust. When the two forces are in opposite directions, the force with a larger absolute value is reduced by 0.7 times the force with a smaller absolute value as the thrust at a fixed point.
The buried guide support is to control the movement along the pipeline or the compensator's moving direction, to ensure that the expansion of the pipe section has an effect on the compensator and to ensure that the pipeline does not fail.
