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、 将二联体的油雾器参与润滑油。南方用10#或20#机械油，北方冬季用防冻机械油或低凝液压油。

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、衔接上需求试压的管路，关闭卸荷阀，翻开高压针阀，气源压力恳求不大于0.7MPa（7kgf/cm?）。

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、调整好二联体的压力，如将气源压力调到0.6MPa,增压后较大爆破压力就抵达105Mpa

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、翻开手动换向阀（俗称手拉阀），气液增压泵开端工作，当抵达设定压力后增压泵中止工作。或看到高压压力表抵达需求的压力时关闭手动换向阀，让泵中止工作。

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、当试件容积较大时，可先翻开电动泵开关将试件注满水，然后将气源压力调理预定爆破压力后翻开手拉阀，增压泵开端工作增压。

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.

耗气量主要是由增压泵的驱动缸活塞的每分钟的往复次数所决议的，在所供气源压力不便的情况下，泵的往复次数决议于排出压力的大或小。当气源压力调高作空载排压时（如对被检大容积容器打压时）就是泵耗气量较大的时分。随着被试容器内的压力逐渐升高，泵的往复速度也逐渐减慢，直驱动气气压与排排出压力成比例平衡后，泵就中止工作，耗气量就等于零。

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.
