The hose hydrostatic testing machine is a type of hydrostatic testing machine specifically designed to test the performance and durability of hoses under different pressure conditions. It simulates the pressure situation in actual use by applying water pressure internally, and detects performance indicators such as the pressure resistance of the hose.
This type of equipment can usually precisely control the water pressure applied inside the hose and perform tests at different pressure ranges. Automated operation, capable of automatically recording test data and generating test reports. Equipment is usually equipped with safety protection devices to prevent safety accidents caused by hose rupture or explosion. Multiple types of tests can be conducted, including static pressure testing, pulse pressure testing, burst pressure testing, etc. This type of equipment is widely used in industrial production, especially in manufacturing and construction industries, to ensure that the quality of hoses meets standards and can be safely and reliably applied in various engineering projects.
The hose hydrostatic testing machine is a device used to test the pressure resistance performance of hoses. During operation, it is necessary to strictly follow the regulations to ensure the accuracy of test results and the safety of operation. The following are the operating procedures for the hose hydrostatic testing machine:
1. Preparation before operation
Check equipment:
Confirm that the testing machine is in normal working condition, and check whether the power supply, air source, and hydraulic system are normal.
Check the water supply to ensure there is sufficient water in the tank and confirm if the water quality meets the requirements.
Confirm that there is no looseness or leakage at the connection between the hose and the testing machine, and ensure that all joints and pipelines are firmly connected.
Check the hose:
Confirm that the specifications of the hose being tested match the settings of the testing machine.
Check for any obvious damage or defects on the surface of the hose to ensure that it is in good condition before the test.
Set experimental parameters:
Set the parameters of the testing machine according to the testing requirements, such as test pressure, holding time, etc.
Confirm that measuring instruments such as pressure gauges and pressure sensors are in normal calibration state.
2. Operation steps
Install the hose:
Fix both ends of the hose onto the fixture of the testing machine, ensuring a secure and leak free connection.
Ensure that the hose is in a natural extension state during the testing process, avoiding excessive bending or twisting.
Water injection and exhaust:
Open the inlet valve, start the water injection system, and fill the hose with water.
Open the exhaust valve and release the air inside the hose until the water flow is stable and there are no bubbles.
Pressure test:
Close the exhaust valve, start the pressurization system, and gradually increase the pressure to the preset value.
During the pressurization process, pay attention to the status of the pressure gauge and hose to ensure a smooth increase in pressure.
After reaching the preset pressure, enter the holding phase, maintain the pressure constant and record the holding time.
Inspection results:
After the pressure is maintained, slowly release the pressure and check the appearance and connection of the hose for any abnormal conditions such as leaks, bulges, or ruptures.
Record experimental data, including pressurization time, holding time, and hose status.
3. Post operation processing
Remove the hose:
Close all valves and ensure that the pressure is completely released before removing the hose.
Check and clean water stains and debris on the testing machine to keep the equipment clean.
Recording and archiving:
Record the test results in detail, including pressure curves, hose status, and other relevant data.
Archive the experimental data and results for future reference and analysis.
Equipment maintenance:
Check the wear and tear of each component of the equipment, and perform maintenance or replacement if necessary.
Regularly inspect and calibrate key components such as pressure gauges and sensors to ensure long-term stable operation of the equipment.
4. Safety precautions
Operators need to undergo training: ensure that all operators have received professional training and are familiar with the operating procedures and safety requirements of the equipment.
Wear protective equipment: Appropriate protective equipment such as goggles and gloves should be worn during operation.
Emergency measures: Familiarize oneself with emergency shutdown operations of equipment and take timely measures in case of accidents.
Stay away from high voltage areas: During the testing process, personnel should avoid approaching high voltage areas to prevent accidental injury.
