Other necessary trials and tests.

Upon successful acceptance by the State Acceptance Commission of a power unit or installation, an act of acceptance of the facility into operation is drawn up in accordance with SNiP 3.01.04-87 (Appendix 5).

An integral part of the production and technological process are narrowly focused special activities, known as commissioning. In the process of carrying out these activities, the equipment is checked for trouble-free operation and safety, the possibility of putting it into operation and bringing it to design indicators. First of all, the documentation of the project to be checked is considered. The equipment is checked and tested for possible failures and emergencies. In addition, it also includes many additional work performed in the process of preparing and conducting individual tests of the entire equipment complex.

Procedure for commissioning

Commissioning is carried out after the installation of the equipment is completed. The main objective of these activities is to comprehensively test the installations being tested. During the check, the degree of their safety and reliability, compliance with the declared design characteristics is determined. Based on the results of the work, all identified shortcomings that impede the normal operation of the equipment are eliminated.

Installation and commissioning are carried out by specialized organizations with which the enterprise concludes a business contract. If the enterprise has trained engineering and technical personnel and the necessary instrumentation, then these works can be performed on your own. These employees belong to the category of operational personnel. They must take a course. After passing the exam, a protocol is drawn up and a certificate is issued for the right to perform commissioning. For workers, a re-test of knowledge is carried out annually, and for engineering and technical workers - once every 3 years.

Commissioning ends with the preparation of a technical report, reflecting all the stages completed, with conclusions and recommendations for further improving the operation of equipment and installations. Thus, this report is the main document characterizing the volume and efficiency of the work performed. Practical experience shows that the cost of start-up and adjustment activities pays off already in the first months of operation. For example, the results of calculations and comparative tests show that due to competently driven start-up and adjustment, fuel savings can be 3-5%.

To perform commissioning, a team of specialists is involved, which should be led by a qualified engineer. The number of workers is determined according to the volume upcoming work usually no more than 5 people. The main activities are carried out by engineering and technical workers, and the personnel of the enterprise are used for auxiliary work.

For each type of equipment, a commissioning program is drawn up, agreed with the management of the enterprise. Its development focuses on practical experience, during which individual nodes are tested, design flaws are identified, and the quality of installation is determined. Great importance is attached to experiments to verify the reliability of all types of equipment, its ability to maintain the specified parameters. The maximum value of the performance of the unit, the stability of its operation at low loads is determined.

Such checks are carried out in sufficient numbers to draw up an indicative regime map, which takes into account the entire range of operational loads. To determine some parameters, instrumentation of the equipment itself is used.

In conclusion, the most important event is carried out for the comprehensive testing of equipment and its inclusion in the work. This operation is carried out only with the permission of the head of the adjusting group. No one should interfere with his orders, except when there is a threat. safe work equipment and maintenance personnel.

Electrical commissioning

Commissioning works are carried out at the final stage of electrical work. During this period, electrical equipment is tested and checked for compliance with the project, the current PUE, technical specifications and documentation of the manufacturer. All units must comply with the declared technological indicators. After all settings, testing and testing have been carried out, conclusions are issued on the operability of the entire installation and each of its components.

Our organization in short time and with high quality will perform a wide range of such works, including commissioning of the electrical equipment system. The company's specialists will carry out activities in several stages:

• Obtaining from the customer and a thorough study of the technical characteristics of the installations, technical documentation and the electrical part of the project, its relationship with the technological processes.
• Preparation of a work program and a project for the implementation of commissioning, including activities related to safety, their coordination with the customer.
• Analysis of the finished documentation, identification of shortcomings and other comments.
• Preparation of instructions technological maps and guidelines on setup issues. Particular importance is attached to protocols and other forms of reporting documentation, preparation necessary tools, appliances and fixtures.

After the preparatory period, commissioning activities are carried out jointly with. A temporary circuit is used to supply voltage to the equipment. When combining work, special attention is paid to compliance with safety regulations. By this time, in the premises with electrical equipment, the implementation of all construction works, heating, lighting and ventilation. The electrical equipment itself is already installed and grounded. Wells, openings and cable channels were closed.

At this stage, the installed electrical equipment is tested by applying voltage through test circuits to individual devices. When performing this operation, electrical installation personnel should not be in the adjustment area. If defects in electrical equipment are detected, they are eliminated by the customer, and installation errors and shortcomings - by the electrical installation organization. Based on the results of the second stage, the employees of the company draw up the following documents:

• Protocol of tests and measurements of insulation.
• protocol.
• Protocol for setting up protections and relay-contactor equipment.
• Executive diagrams of objects subject to power supply, connected to voltage.

At the next stage, individual tests of electrical equipment are carried out, in which the voltage is supplied according to normal working scheme. First of all, for electrical installations, input is performed operating mode and issuance of personnel permits in accordance with safety regulations. After that, the adjusters adjust the equipment parameters, test protection, control and signaling schemes. Before testing technological equipment, it is necessary to adjust and check the operation of the electrical equipment at idle.

After the company's specialists conduct individual tests, the electrical equipment will be considered accepted for operation. Based on the results of the tests, all the necessary documents will be drawn up and transferred to the customer:

• Test protocols for grounding and zeroing.
• Test protocols for electrical equipment at high voltage.
• Principal executive schemes, as in the previous stage.

The rest of the documentation is provided to the customer within two months after the equipment is put into operation. For objects of increased technical complexity, this period is extended to four months. At the end of this stage, an act of technical readiness is drawn up for conducting a comprehensive testing of electrical equipment.

Comprehensive testing is carried out according to special programs agreed with the customer. During this event, the interaction of electrical equipment systems and electrical circuits in various operating modes is checked. Parameters in individual devices and functional groups are adjusted and configured, their mutual connections are provided, and specified operating modes are created. Electrical installations are tested according to the full scheme, which makes it possible to prepare and conduct a comprehensive testing of technological equipment.

Equipment commissioning

In order to put the mounted process equipment into operation, it is necessary to perform commissioning work. The volume of these activities can be up to 20% of the entire project. These works are carried out at the final stage, before putting the equipment into operation.

In our organization, we qualitatively and quickly perform commissioning of all major types of equipment. The company's specialists will carry out the following activities:

• Check the compliance of the project documentation with the actual execution.
• They will prepare and test technological lines.
• Perform revision, testing and calibration of various instruments and automation.
• Individual components and assemblies, auxiliary systems will be checked by testing method, dynamic equipment will be run in.
• Organize activities for the complex testing of the facility and its commissioning.
• Conduct staff training for the subsequent operation of the equipment.

As a rule, the organization of commissioning works at any object is carried out at the last terms of construction and installation works. Already during this period, engineers discovered possible inconsistencies between the design documentation and the installed equipment. Because of this, malfunctions may occur in the future, so it is very important to eliminate all shortcomings in a timely manner. This stage has great importance and guarantees the reliable operation of the facility in the future.

Our commissioning organization offers a full range of services, from the adjustment of individual technological elements to complex facilities of various industries.
