Problems solved by technology

However, in the actual situation, due to the uneven distribution of the mass density of the impeller during the manufacturing process, the asymmetrical position of the blade assembly, and deformation after heat treatment, the unbalanced mass during dynamic balancing is too large, and sometimes the unbalanced amount reaches several kilograms.
In this way, the work of dynamic balancing and de-weighting becomes very difficult, the operation is complicated, time-consuming and labor-intensive, and brings a lot of workload to the balancing workers. At present, the dynamic balancing and de-weighting of the impeller usually requires one person to operate the grinder. One person turns the impeller, which takes time and effort when the unbalance is large, and there is a huge hidden danger in operation safety
Therefore, how to quickly remove the large unbalance of the impeller to meet the technical requirements has become a major technical barrier in the balancing work, seriously affecting the rotor balancing efficiency

Abstract

The invention provides an impeller dynamic balance de-weight automatic turning device. The device comprises a base, a universal clamp fixed at an outlet position of an impeller, a cylinder, a cylindersupport arranged on the base and used for supporting the cylinder, and a first non-contact probe and a second non-contact probe arranged at the other side of the impeller opposite to an starting point position and a terminal position of a de-weight angle range of the impeller, one end of the cylinder is hinged to the base, the other end of the cylinder is hinged to the universal clamp, the cylinder support is provided with a solenoid directional valve connected with the cylinder and used for controlling reciprocating operation of the cylinder, and the first non-contact probe, the second non-contact probe and the solenoid directional valve are separately connected with an electrical control device. The invention also provides an impeller dynamic balance de-weight automatic turning method.According to the impeller dynamic balance de-weight automatic turning device and method, the de-weight efficiency is high, and the operation is convenient.

Description

technical field [0001] The invention relates to the technical field of centrifugal compressor dynamic balance, in particular to an impeller dynamic balance de-weighting automatic barring device and method. . Background technique [0002] In petrochemical, oil refining and other equipment, centrifugal drums and compressors are one of the core equipment, and with the continuous increase of the processing capacity of my country's oil refining equipment, the volume of the impeller and rotor of the compressor is also increasing, and the rotor assembly The final weight has reached tens of tons, or even more. However, in the actual situation, due to the uneven distribution of the mass density of the impeller during the manufacturing process, the asymmetrical position of the blade assembly, and deformation after heat treatment, the unbalanced mass during dynamic balancing is too large, and sometimes the unbalanced amount reaches several kilograms. In this way, the work of dynamic b...
