注意事项:高压截止阀为锥形针阀,封闭力不能大于18NM。在升压过程,截止阀如有渗漏,正确的操作应是卸压后再重新封闭。避免用力过大而损坏阀芯,缩短该阀使用寿命。
Notes: High-pressure globe valve is conical needle valve, sealing force should not be greater than 18NM. In the boost process, if the globe valve leaks, the correct operation should be to re-seal after pressure relief. Avoid excessive force and damage the spool, shorten the service life of the valve.
操作程序
Operation procedure
1、 将二联体的油雾器参加润滑油。南边用10#或20#机械油,北方冬天用防冻机械油或低凝液压油。
1. The binary oil mist is added to the lubricating oil. 10 # or 20 # mechanical oil is used in the South and antifreeze mechanical oil or low pour point hydraulic oil is used in the north in winter.
2、连接上需求试压的管路,封闭卸荷阀,翻开高压针阀,气源压力要求不大于0.7MPa(7kgf/cm2)。
2. Connect the pipeline that needs pressure test, close unloading valve, turn over high pressure needle valve, and the gas pressure requirement is not more than 0.7MPa (7kgf/cm2).
3、调整好二联体的压力,如将气源压力调到0.6MPa,增压后最大爆炸压力就到达
3. Adjust the pressure of the binary system properly. If the pressure of the gas source is adjusted to 0.6 MPa, the maximum explosion pressure will reach after pressurization.
4、翻开手动换向阀(俗称手拉阀),气液增压泵开端工作,当到达设定压力后增压泵停止工作。或看到高压压力表到达需求的压力时封闭手动换向阀,让泵停止工作。
4. Open the manual reversing valve (commonly known as hand-pulled valve), the gas-liquid booster pump starts to work, and 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 to stop the pump.
5、当试件容积较大时,可先翻开电动泵开关将试件注满水,然后将气源压力调节至预订爆炸压力后翻开手拉阀,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 predetermined explosion pressure, then the hand-pulled valve can be turned on, and the booster pump works at the beginning to boost pressure.
最大耗气量及配套的空压机
Maximum air consumption and matching air compressors
耗气量首要是由增压泵的驱动缸活塞的每分钟的往复次数所决定的,在所供气源压力不方便的情况下,泵的往复次数决定于排出压力的大或小。当气源压力调至最高作空载排压时(如对被检大容积容器镇压时)就是泵耗气量最大的时分。随着被试容器内的压力逐步升高,泵的往复速度也逐步减慢,直至驱动气气压与排排出压力成份额平衡后,泵就停止工作,耗气量就等于零。
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 gas source is adjusted to the highest level for no-load discharge (e.g. when the pressure of the large volume vessel is suppressed), it is the time when the pump consumes the greatest amount of gas. The reciprocating speed of the pump slows down as the pressure in the vessel increases gradually, until the balance between the driving gas pressure and the exhaust pressure components, the pump stops working and the gas consumption is equal to zero.
