Mechanical equipment installation and construction technology

Prepare construction organization design or special construction plan

Prepare equipment entry plans, plan for the use of resources such as labor, materials, and equipment, and organize them in an orderly manner.

On-site facilities should have starting conditions

Unpacking the device

When the machinery and equipment are unpacked, the construction company, construction unit, supervision unit, and supplier

Box number, box number and packaging

Equipment names, specifications and models, important parts and components also need to be checked and accepted according to quality standards

Random technical documents (such as instructions for use, certificates of compliance, packing lists, etc.) and special tools

Whether there is a defect, whether the surface is damaged or rusted

Other matters that need to be recorded

Basic measurement line

Set baselines and benchmarks

The construction unit that undertakes the civil engineering works shall hand over the measurement network points, including the crucial main axis, together with the transfer of the factory building and the basic conditions.

in principle

Easy to install and test

Helps to maintain without being destroyed

Sculpted clearly and easily

Claim

Prior to the placement of machinery and equipment, according to the layout of the process and according to the measurement control network or related building axis, edge line, elevation line, delineate the installation of the baseline and reference point

For mechanical equipment that has mechanical connection with other equipment, a common installation reference line and reference point should be designated

For mechanical devices that have no mechanical connection with other devices, the allowable deviation of the mounting base line for locating the base surface, line or point is ±20mm, and the allowable deviation from the mounting reference point is -10~+20mm.

For mechanical equipment that has mechanical connection with other equipment, the allowable deviation of the positioning base surface, line or point from the installation reference line is ±2mm, and the allowable deviation from the installation reference point is ±1mm.

Permanent baseline and benchmark

Longer installation periods and production inspections require long-term retention of baselines and benchmarks, permanent centered targets and permanent reference points
