ower management company Eaton – now part of Danfoss Power Solutions (Sealing Technology, September 2021, page 2) – lately expanded its product portfolio with the addition of the sturdy WALRINGplus delicate seal chopping ring system, optimised for thin-wall tubing.
Featuring a two-edge chopping ring, with additional delicate sealing for each possible leak paths, this tube fitting system enables easy, secure and repeatable assembly and dependable, leak-free operations.
It is designed to fulfill demanding requirements, involving hydraulic tube fitting in applications together with use in agriculture, construction, business autos, discrete manufacturing, rail transportation and different industries.
It is suitable for use with thin-walled tubes and, therefore, helps environment friendly weight and gas discount of cell equipment and moving components of stationary machinery.
Correct meeting is essential to tube becoming efficiency and WALRINGplus is designed to stop excessive or insufficient tightening. เกจวัดแรงดันsumo -stop function supplies a tangible torque increase when the top of an meeting is reached, so no torque or distance measurement is required.
In addition, a significantly decrease force is required to pull the cutting ring over the tube – making assembly easier, sooner and safer, while decreasing the chance of injury to the soft seal. The O-ring groove position additionally permits frequent reassembly, with out affecting performance.
To get rid of the danger of leaks that may create expensive harm and downtime, WALRINGplus additionally addresses their common root causes.
Soft sealing prevents leakages if: tubes or studs are slightly scratched, the fluid temperature fluctuates or the retention pressure is lowered. Problems caused by low meeting torque also could be recognized earlier than the chopping ring is pulled from the tube – decreasing the danger of a catastrophic failure in software.
The bespoke M-R7 machine additional reduces meeting time and the effort required for WALRINGplus in addition to the chance of leaks. By automating the method of cutting-ring meeting and tube-forming, this machine helps ensure optimum system performance while additionally lowering the required torque and rotrotation.
Specifications of WALRINGplus: • metal chopping ring with Viton O-rings; • for tube sizes 6–42 mm; • complies with ISO 8434-1; • excessive burst-pressure exceeding four:1 security factor; • working pressure up to 500 bar (L-series) and 800 bar (S-series); and • helps dry meeting with metal parts.
