Description

Compressor foundation bolt and mounting structure thereof

Technical Field

The utility model relates to a rag bolt and mounting structure thereof, especially a rag bolt of compressor basis installation usefulness and mounting structure thereof.

Background

The compressor is widely applied to the fields of chemical industry and petrochemical industry. The compressor foundation, unlike the building foundation, will be subjected to static and dynamic loads. Because of the dynamic nature of the load and the elasticity of the soil, the specifications and data for designing building foundations cannot be used for compressor foundations. Therefore, much lower soil bearing capacities than those specified for urban construction should be used, typically one quarter to one third of their value. The low soil bearing capacity makes the natural frequency of the foundation higher, prevents resonance and reduces the possibility of transmitting vibration. If the compressor foundation is designed to ignore these factors, the weight of the foundation and the elasticity of the soil may add up, creating a natural frequency that, if within the compressor operating frequency range, would result in extreme movement of the foundation.

Typically the size of the compressor cylinder and the weight of the reciprocating components are determined by the operational process requirements and compressor characteristics. It is often impractical for the inertial forces of compressor operation to be fully balanced by itself. The design of the compressor base is therefore intended to absorb unbalanced forces and moments to reduce any vibrations.

The compressor is installed on the foundation and foundation, and the foundation and foundation are used for absorbing unbalanced force and moment of the compressor and conducting the unbalanced force and moment into soil, and the alignment and assembly gaps of the parts of the compressor unit are kept. Without a good foundation, the centering and assembly clearance of each part of the compressor set cannot be kept, and problems can occur, which affect the safe operation of the compressor.

All pre-buried rag bolt in the compressor basis usually, rag bolt's kind has a lot of, links to each other compressor unit and basis through rag bolt. In practice, the sleeve is embedded during foundation construction, and the anchor bolt with the anchor plate is inserted when the compressor is installed. In order to have great accommodation space, make things convenient for the alignment of compressor, the diameter of rag bolt sleeve pipe selection is great, and the area of contact of rag bolt anchor slab and basis can reduce, and the anchor slab is direct to be in contact with the concrete face, and effective area of contact is less, and it is also comparatively difficult to adjust mounted position, and in addition, under the more condition of rag bolt quantity, rag bolt sets up the position and highly all more difficult control of top and basis, leads to the fact certain degree of difficulty for the construction.
