1. Equipment inspection and maintenance
Regularly check the equipment status: Before use, check the various components of Pressure Test Pump in detail, including the pump body, pressure gauge, connecting pipes and valves, to ensure that the equipment is intact.
Check the electrical system and grounding: Ensure that the electrical system works normally and the grounding is reliable to avoid the risk of electric shock.
Calibrate the pressure gauge: Ensure that the pressure gauge is sensitive and effective, and calibrate it regularly.
Lubrication and maintenance: Regularly check and replace lubricating oil to ensure that the equipment is well lubricated.
2. Operation specifications
Wear personal protective equipment: Operators must wear personal protective equipment before operation, including safety helmets, protective gloves, goggles, etc.
Preparation before operation: Ensure that the pressure test piece is neat, clean and easy to inspect. The water inlet and drain outlet should be arranged before the pressure test.
Slow pressure increase: The pressure increase must be slow, and overpressure is not allowed. It is forbidden to hammer the pressure test piece after it reaches a certain pressure.
Special operation: Pressure Test Pump should be operated by a special person. There must be more than two people for each pressure test, and there must be a special person in charge.
3. Safety devices
Equipped with safety valves and pressure relief devices: The pressure test system should be equipped with necessary safety valves, pressure gauges and pressure relief devices to ensure automatic pressure relief when the pressure is too high.
Overload protection device: Ensure that the Pressure Test Pump is equipped with an overload protection device to avoid motor overload.
4. Environment and site management
The construction site meets safety requirements: The construction site should comply with the relevant national regulations on occupational safety and health and fire prevention, and the equipment on the construction site should be neatly stacked and clearly marked.
Avoid dangerous environments: The equipment should ensure air circulation during operation, and it is strictly forbidden to operate in environments such as humidity, excessive dust, harmful corrosive gases and media.
On-site safety signs: Set up obvious safety warning signs at the pressure test site to ensure the safety of on-site personnel.
5. Precautions during pressure testing
Avoid working under pressure: If defects are found in the pressure test parts and pipelines, the pressure should be reduced to zero before processing, and working under pressure is not allowed.
Post-pressure test treatment: After the pressure test is completed, drain the water and relieve the pressure before removing the bolts. After the pressure test in winter, the water must be drained immediately to prevent freezing of the equipment.
Tighten the bolts to bear force evenly: Tighten the bolts to bear force evenly to prevent local deformation and cracking.
