New dimension type

02.04.2014

Acceptance tests for Р-20 shock absorber prototype (axial load up to 20 ton) were completed at the Combustion Engineering Facility under contract with Rostovskaya nuclear power plant.

 

The tests were conducted per specialized test procedure using MI-600 Test Machine that simulates shock absorber’s life cycles as well as all the loads. Testing was actually supervised by designer — ОАО «ОКB Gidropress», representatives of Rostovskaya Nuclear Power Plant, representatives of Directorate for Manufacturing of Civil Products, representatives of Chief Process Engineer’s Department as well as other structural units of JSC «Votkinsky zavod». Prototype’s operability was tested for more than 20 hours within four temperature ranges from +30 to +145 °C. The committee determined that the shock absorber has passed the test. As a reminder, our company commenced manufacturing of shock absorbers for nuclear power plants two year ago. At present, we learned to manufacture six out of eight dimension types. The first batch of finished products has already been shipped to Leningradskaya Nuclear Power Plant-2 where they will be operated.

 

 

 

The smallest shock absorber (weight — 48 kg) is capable of withstanding 5 ton load, the biggest shock absorber (weight — more 800 kg) is capable of withstanding 450 ton load (please see the picture).
