    • Process for starting a pump intended to pump a liquid contained in a tank and to produce a substantially constant outlet pressure (setpoint pressure), according to which: 1. the temperature (T1) of the liquid held in the tank is determined and compared to a setpoint temperature (T0); 2. if the temperature (T1) is greater than the setpoint temperature (T0), the pump is actuated; 3. if the temperature (T1) is less than or equal to the setpoint temperature (T0), the tank is heated for a time tl; then 4. the pump is actuated for a time t2 during which the pump outlet pressure is measured; 5. if this pressure is stable and in an acceptable margin of the setpoint pressure, the pump is kept going; 6. if this pressure is not stable and/or is not in the acceptable margin of the setpoint pressure, the pump is stopped and the tank is heated for a time t3, at the end of which steps 4 to 6 are repeated.
    • 启动用于泵送包含在罐中的液体并且产生基本上恒定的出口压力(设定点压力)的泵的过程,根据以下步骤:1.保持在罐中的液体的温度(T1)被确定并与 设定点温度(T0); 2.如果温度(T1)大于设定点温度(T0),则启动泵。 3.如果温度(T1)小于或等于设定点温度(T0),油箱加热一段时间t1; 然后泵激活一段时间t2,在此期间测量泵出口压力; 5.如果该压力稳定并且处于设定值压力的可接受余量,泵将继续运行; 6.如果该压力不稳定和/或不在设定值压力的可接受余量内,泵停止并且罐被加热一段时间t3,在其结束时重复步骤4至6。
