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、 將二聯(lián)體的油霧器參與潤(rùn)滑油。南方用10#或20#機(jī)械油，北方冬季用防凍機(jī)械油或低凝液壓油。

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、銜接上需求試壓的管路，關(guān)閉卸荷閥，翻開(kāi)高壓針閥，氣源壓力懇求不大于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、調(diào)整好二聯(lián)體的壓力，如將氣源壓力調(diào)到0.6MPa,增壓后較大爆破壓力就抵達(dá)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、翻開(kāi)手動(dòng)換向閥（俗稱手拉閥），氣液增壓泵開(kāi)端工作，當(dāng)?shù)诌_(dá)設(shè)定壓力后增壓泵中止工作?；蚩吹礁邏簤毫Ρ淼诌_(dá)需求的壓力時(shí)關(guān)閉手動(dòng)換向閥，讓泵中止工作。

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、當(dāng)試件容積較大時(shí)，可先翻開(kāi)電動(dòng)泵開(kāi)關(guān)將試件注滿水，然后將氣源壓力調(diào)理預(yù)定爆破壓力后翻開(kāi)手拉閥，增壓泵開(kāi)端工作增壓。

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.

耗氣量主要是由增壓泵的驅(qū)動(dòng)缸活塞的每分鐘的往復(fù)次數(shù)所決議的，在所供氣源壓力不便的情況下，泵的往復(fù)次數(shù)決議于排出壓力的大或小。當(dāng)氣源壓力調(diào)高作空載排壓時(shí)（如對(duì)被檢大容積容器打壓時(shí)）就是泵耗氣量較大的時(shí)分。隨著被試容器內(nèi)的壓力逐漸升高，泵的往復(fù)速度也逐漸減慢，直驅(qū)動(dòng)氣氣壓與排排出壓力成比例平衡后，泵就中止工作，耗氣量就等于零。

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.
