Hydraulic cylinder disassembly precautions
Hydraulic cylinders are commonly used in jacking operations. They are widely used jacking tools. Allison hydraulic cylinders are designed to operate at pressures ranging from 0-200 MPa. When we need to remove the hydraulic cylinder maintenance, some things must be paid attention to.First, telephone consultation by the factory, the factory's technical personnel for technical guidance.2. Care shall be taken to avoid contamination of the parts caused by the environment.3. Disassembled parts and components shall be covered with plastic sheets.IV. The disassembled parts shall be inspected. If there is any abnormality, they shall be repaired or replaced.Above for you to introduce a few hydraulic cylinder dismantling matters to pay attention to, I hope to help you. Allerson hydraulic cylinder shall pay attention to the disassembly method, to avoid improper operation caused by the damage of hydraulic cylinder parts resulting in irreparable consequences. DetailComprehensive destructive test for Ellison bolt tensioner
Objective: To test the compression capacity and load of the bolt tensioner.Test tools: AHP3500 pneumatic hydraulic pump, UHH300 high pressure tubing, ultra-high pressure quick connectorSpecification of bolt stretcher: M42 interchangeable bolt stretcher specific parameters see the drawing:Preparation before the test:Connect the pneumatic hydraulic pump with the bolt stretcher, and check whether the pipelines are well connected. In order to ensure the safety of the pipeline, 15M long high pressure oil pipe is used, and the safety plate is used.Test procedure: divided into three stepsStep 1: Press to design pressure and hold pressure for 10 minutes.The second step: press to 200MPa and then hold the pressure for 10 minutes.Step 3: press until the bolt tensioner leakage test is over.Do not try this experiment for non-professionals.
