The invention discloses a hydrostatic pressure detection system of a compressed natural gas filling machine, and specifically relates to the technical field of hydrostatic pressure detection of high-pressure equipment. It solves the problem that the existing hydrostatic pressure testing equipment can only perform hydrostatic pressure testing of the equipment under a specific pressure value, and the testing device has errors in the testing of micro leaks. The hydraulic static pressure detection system of the compressed natural gas dispenser includes high-pressure hydraulic pressure generating equipment, hydrostatic pressure detection equipment and monitoring equipment. A pressure gauge and an overflow valve are installed between the liquid container and the water inlet valve. The hydrostatic pressure detection equipment includes a lifting table, which is equipped with multiple detection ports. Each detection port is fixedly connected to an automatic control valve, and the outlet of the automatic control valve is set. There is a card holder, a plurality of test bottles are arranged above the card holder, and a camera is arranged above each test bottle.
Description
technical field [0001] The invention relates to the technical field of hydrostatic pressure detection of high-pressure equipment, in particular to a hydrostatic pressure detection system of a compressed natural gas dispenser. Background technique [0002] Environment and energy are two topics of common concern to human beings, and they are also important topics in the sustainable development strategies of various countries. As clean energy, natural gas energy is widely used in daily life and production. Compressed natural gas, or CNG, has become the main form of natural gas energy utilization due to its good social and economic benefits. As the main power source of CNG filling station, CNG terminal dispensing machine has been operating under high pressure. Therefore, the components in the CNG terminal dispensing machine must have good pressure-bearing performance and anti-leakage performance. Equipment hydrostatic pressure testing.
