The blasting (pressure-withstanding) experimental equipment is a new type of pressure-testing device developed by our company according to the working principle of the pneumatic boosting device imported from abroad and separated from the theoretical situation of our country. Our company's consumption of explosion (pressure) experimental equipment includes: hose pressure burst test bench, hose pressure pulse test machine, automotive parts pressure test bench, the equipment conforms to other general and specialized international and domestic related pressure component test standards. It is mainly used for pressure, explosion, leakage and length change experiments of various hoses. Experimental media: water or oil and other non-corrosive liquids.
1. Participate in the lubricating oil with the binary oil mist. The South uses 10 # or 20 # mechanical oil, and the North uses antifreeze mechanical oil or low pour point hydraulic oil in winter.
2. Connect with the pipeline requiring pressure test, close the unloading valve, turn over the high-pressure needle valve, and the pressure of air source is not more than 0.7MPa (7kgf/cm?).
3. If the pressure of the binary system is adjusted properly, if the gas source pressure is adjusted to 0.6 MPa, the maximum blasting pressure will reach 105 Mpa after pressurization.
4. Open the manual reversing valve (commonly known as hand-pulled valve) and start the work of the gas-liquid booster pump. When the set pressure is reached, the booster pump stops working. Or when the pressure gauge reaches the required pressure, close the manual reversing valve and let the pump stop working.
5. When the volume of the specimen is large, the switch of the electric pump can be turned on first to fill the specimen with water, then the air pressure can be adjusted to the preset blasting pressure, then the hand-pulled valve can be turned on, and the booster pump can work at the beginning to boost pressure.
The gas consumption is mainly determined by the reciprocating times per minute of the piston of the driving cylinder of the supercharged pump. In the case of inconvenient supply pressure, the reciprocating times of the pump are determined by the discharge pressure. When the pressure of the air source is adjusted to the highest level for no-load discharge (e.g. when the pressure is applied to the large volume vessel under inspection), the pump consumes the most air. As the pressure in the vessel increases, the reciprocating speed of the pump slows down gradually. When the driving gas pressure is proportional to the discharge pressure, the pump stops working and the gas consumption is equal to zero.
