As the core equipment of enterprise production, compressor equipment's stable and safe operation has a significant
impact on the economic benefits of the enterprise. In chemical enterprises, due to the particularity of the working
environment, there are dangerous operations such as high temperature and pressure, flammable and explosive
materials, and hazardous substances, which can cause serious safety accidents in production.
In recent years, the production conditions of chemical enterprises have been continuously improved, but various
safety accidents still exist, and safety accidents caused by compressor equipment during production and operation
still account for a large proportion. Control is carried out from the source of compressor design, including design,
procurement, on-site installation, commissioning and operation, and the production process is formulated with strict
operating procedures and maintenance checks at all levels to ensure the safe operation of the equipment.
Characteristics of compressor equipment installation projects in chemical companies
1. Process characteristics of compressor equipment in chemical enterprises
In chemical enterprises, since most compressors come into contact with production materials, most of which are
flammable, explosive, toxic, and corrosive, the requirements for compressors are also different, so the requirements
for compressors There are strict requirements for model selection, materials, sealing, etc. If the compressor cannot
meet the chemical production process, there will be economic problems such as material leakage and damage to
equipment at the least, and safety accidents causing personal injury at the worst. Secondly, compressor equipment
has a variety of power sources, mainly electrical energy, and also chemical energy, air energy, thermal energy,
electromagnetic energy, etc. The third is special operating parameters and more working conditions, such as high
and low pressure, high and low temperature, high and low speed, emergency cut-off and frequent start and stop, etc.
Fourth, it has high sealing performance requirements.
2. Technical requirements for installation of compressor equipment in chemical enterprises
● First of all, make preparations.
Carry out the collection of technical data on the selected compressor and related supporting equipment, understand
the required working environment and process flow of the facility, and complete the design of the equipment production
stage drawings based on this.
At thesame time, before starting foundation pouring, attention should be paid to the implementation and stabilization of
accurate calibration equipment,comprehensive inspection of the operating status of the equipment, and control of
installation deviations. Since compressor equipment needs to ensure a high installation accuracy value, the installation
process must be optimized based on specific specifications, especially around the construction requirements of the
machinery and the actual production process, to minimize the deviation value.
● Strictly control welding quality.
Quality control of welding in installation projects is also very critical. When welding, operators must focus on controlling
the interlayer temperature, front layer welding status, arc voltage and position, welding setting method, and welding
power source according to the process instructions and welding operation plan. and speed, electrode or wire diameter
selection, welding sequence, etc. After welding is completed, the quality of the weld should be inspected, with special
attention to the appearance and size of the weld. During the quality control process, internal defects of the weld,
surface smoothness of the weld, appearance defects, reinforcement dimensions, leg length of the weld, etc. must be
well managed.
● Lubrication and explosion-proof.
For some special processes, the actual use of lubricating oil must be carefully tested on the compressor equipment.
At the same time, the selection of lubricating oil should take into account the influence of movement speed, load
properties, ambient temperature, etc., in order to improve the quality of lubricating oil. Performance, a certain amount of graphite powder can be added to form a tough oil film, which can play a buffering role. If the electrical
equipment is located in a flammable and explosive place, it needs to ensure good explosion-proof sealing performance
and static electricity removal function, and the electrical equipment must meet the explosion-proof standards for gas
explosion hazardous places at maximum load.
