【摘要】：目前石油钻机液压盘刹的动力系统均是通过电机带动液压泵产生压力。常规设计是配备两台泵组,互为备用,这种形式虽有双泵的冗余设计,但驱动的最终源头都是电力。并且一般在使用过程中,泵启动后就不能停止,系统需持续提供压力,如果停电或没电时系统将无法工作。因此将传统的双泵形式设计为主泵为电机泵、备用泵为气动泵的双驱动形式,保证了刹车设备在停电或没电的状态环境下仍能工作。同时提高泵压、增大蓄能器容量,采用减压阀实现高压储能低压使用,既能让主泵实现间歇性工作,又能克服气动泵流量较小的限制。气动泵的驱动压力小,不会产生漏电和操作上的危险。此设计既节省了电力,又起到节能减排的效果。
[Abstract]:At present, the power system of hydraulic disc brake of oil drilling rig is driven by motor to generate pressure. Conventional design is equipped with two sets of pumps, which are each other's reserve, although there is redundant design of double pumps in this form. But the ultimate source of the drive is electricity. And in general, during use, the pump cannot be stopped after it is started, and the system needs to provide continuous pressure. If the system is unable to work when power is off or without electricity, the traditional dual pump is designed as a motor pump, and the backup pump is a double drive form of a pneumatic pump. It ensures that the brake equipment can still work under the condition of power failure or no electricity. At the same time, the pump pressure is increased, the accumulator capacity is increased, and the pressure reducing valve is adopted to realize the use of high pressure energy storage and low pressure, so that the main pump can work intermittently. This design can not only save electricity but also save energy and reduce emission.
