    • Disclosed is an engine speed control method, which is used to control an output speed of an engine of a jib-type engineering machine when a jib operates, and comprises: step A, detecting a load pressure of a hydraulic system and a moving speed of the jib; step B, a central control unit, according to the load pressure and the moving speed of the jib, determining a target speed of the engine; and step C, the central control unit sending the target speed of the engine to an engine control unit, and the engine control unit, according to a current speed value fed back by the engine, performing speed closed-loop adjustment, so that the current speed of the engine consists with the target speed of the engine. Further disclosed are an engine speed control system and a jib-type engineering machine having the engine speed control system. The engine speed control method has a high degree of automation and high adaptability.

    • A system and method for measuring mass flow of a non-gaseous phase (4) of material such as a solid particulate are described. The material flows through a conduit of which a section (14) is heated or cooled. One temperature sensor (6) is provided upstream of this section and at least another temperature sensor (7, 8) is provided downstream of it. These temperature sensors are adapted to measure the temperature of material in the non-gaseous phase directly. The section is heated or cooled for a first period of time and then neither heated nor cooled for a second period. A third temperature sensor (10) is provided in good thermal contact with the heated or cooled section - this temperature sensor. The temperature sensors measure the temperature of the non-gaseous phase of the material flowing the conduit in at least the second period of time. The mass flow of the non-gaseous phase of the material is calculated from the measurements of temperature.
    • 描述了用于测量诸如固体颗粒的材料的非气相(4)的质量流量的系统和方法。 材料流过其中加热或冷却部分(14)的导管。 一个温度传感器(6)设置在该部分的上游,并且至少另一个温度传感器(7,8)设置在其下游。 这些温度传感器适于直接测量非气相物质的温度。 将该部分加热或冷却第一个时间段,然后不加热或冷却第二个时间段。 第三温度传感器(10)与被加热或冷却的部分(该温度传感器)具有良好的热接触。 温度传感器至少在第二段时间内测量流过导管的材料的非气相的温度。 材料的非气相的质量流量根据温度的测量值计算。
