The Forensic expert kollegium carries out expertise of all types of industrial pumping equipment (liquid pumps, air compressors), which are used in water supply systems, heating, industrial water and liquid supply, cooling and air conditioning, maintaining constant pressure, etc.
Pumps (pumping units) usually consist of two main parts:
- pumping part;
- power section (electric motor, etc.).
Expertise of pumping units at the Forensic expert kollegium allows you to determine:
- the actual technical condition and performance of the pumps;
- hidden defects, as well as the reasons for the destruction of units and failures in work;
- compliance with the requirements of technical regulatory legal acts, as well as engineering and operational documentation.
During the operation of pumping equipment, the following types of malfunctions and their causes most often occur:
- Inconsistency of the actual technical characteristics of the pump (pumping equipment) with the passport or specifications stated in the technical task.
The main characteristics of the pumps are: head, flow rate and efficiency. The inconsistency of these characteristics with the passport or specifications of the technical task is most often due to the inconsistency of the parameters of the impeller of the pumping part of the pumping unit, incorrect selection of the electric motor.
There are also cases when a pump unit tested under the conditions of the manufacturer plant with confirmation of technical characteristics (head, flow rate and efficiency), when delivered to the operating organization, may not provide these parameters due to the fact that the manufacturer (supplier) of the pumping unit did not consider the features of operation, such as hydraulic resistance, the required lifting height of the liquid, etc. while selecting the pump. - Increased vibration level.
This defect is most often caused by defects in the installation of the pumping unit (non-observance of the alignment of the installation of the pumping and power parts of the pumping unit, improper maintenance). - Failure of rolling and plain bearings.
These defects are most often caused by improper lubrication of bearings, manufacturing defects of bearings. - Corrosive wear of the pump working units due to the non-conformity of the material of these parts to the operating conditions (low resistance to aggressive media).
To determine the technical condition and characteristics of pumping units, the experts of the Forensic expert kollegium measure the technical parameters of the pump operation (pressure, flow, power consumption, pressure, etc.).
If necessary, vibrodiagnostics of the pump unit assemblies, linear-angular measurements of the pump units, control of the correct installation of the pump are carried out.
During the pumping equipment expertise, the specialists of the Forensic expert kollegium give answers to these questions:
- Do the actual technical characteristics of the pump correspond to the requirements of the passport (technical task)?
- What is the reason for the inoperability of the pumping unit?
- Does the quality of the installation work performed meet the requirements of the technical documentation?
