A portable hydraulic testing machine is a small device used to test the pressure resistance and sealing performance of various pipelines, pressure vessels, boilers, valves, and other equipment, ensuring their safety and stability in pressure environments. It simulates the pressure load of the device under working conditions by injecting water into the interior of the tested device and applying a certain pressure to check for water leakage, explosion, or other safety hazards.
Detailed composition of portable hydraulic testing machine:
Pressure system: Pneumatic pumps are suitable for testing scenarios that require low flow and high pressure, saving manpower and allowing for rapid pressurization. The maximum pressure range can reach several tens of megapascals (MPa).
Pressure gauge: The portable hydraulic testing machine is also equipped with a digital display gauge, which displays the water pressure in the system in real time and can more accurately monitor pressure changes. The dial indicates the safe pressure range to help operators ensure that the test pressure does not exceed the designed tolerance range of the equipment.
Safety valve: Automatic pressure relief to protect equipment and prevent excessive pressure. It can automatically open after reaching the set pressure, ensuring safety.
Regulating valve: used to precisely control the amount of water and pressure entering the tested equipment to achieve the set test pressure and maintain it for a period of time, in order to observe the reaction of the equipment under pressure.
Water storage system: Portable hydraulic testing machines generally come with a small water storage tank or are supplied with water from an external source to provide the required amount of water for testing. Water is a commonly used testing medium because it is safer than gas and has lower compressibility in pressure testing, making it less prone to dangerous explosions.
High pressure hose: a hose that is resistant to high pressure and explosion-proof, connecting the hydraulic testing machine and the equipment to be tested, ensuring good sealing performance even under high pressure.
Quick connector: facilitates the connection of equipment with different types of pipelines, containers, and other devices, improving testing efficiency.
Drainage system: After the test is completed, the drainage valve can quickly release the water pressure inside the testing equipment and discharge excess water, avoiding residual pressure from causing harm to the equipment or operators after the test is completed.
During work, connect the portable hydraulic testing machine to the tested equipment (such as pipelines or containers) through high-pressure hoses and quick couplings to ensure sealing. Inject water into the testing equipment and monitor the pressure value through a pressure gauge. Generally, the pressure will be gradually increased until the required test pressure is reached. Maintain the test pressure for a certain period of time, such as 10 minutes or longer, to test the pressure resistance and sealing performance of the equipment. If there is no pressure drop or leakage during the pressure maintenance period, it indicates that the equipment is normal. After the test is completed, the internal water pressure is released through the drainage system to drain the water and ensure the safety of the equipment and environment.
Due to its small and lightweight size, easy operation, and suitability for on-site use, portable hydraulic testing machines play an important role, especially in large equipment or fixed pipeline systems that are inconvenient to move. Water, as a testing medium, is safer than gas testing and avoids the risk of explosion caused by the compressibility of the medium. No complex operating procedures are required, and both manual and electric pressurization systems are easy to master, suitable for on-site workers to operate. Capable of testing various devices such as pipelines, containers, boilers, valves, etc., with a wide range of application scenarios. Portable hydraulic testing machines are important tools in industrial, construction, and public facility maintenance, ensuring the safety and reliability of equipment in high-pressure environments.
