摘要： When an oil-flooded screw compressor is started up in a cold environment after a long halt, start-up torque increases due to the increased viscosity of the oil that has long stayed inside the working chambers of the compressor. This has necessitated drive means with a larger capacity than that required for normal operation.An oil-flooded screw compressor according to the invention comprises: a casing; a pair of rotors each having screw-thread-shaped groove and being housed in the casing; an electric motor for rotationally driving the pair of rotors; a control device for controlling the electric motor; an oil feeding mechanism for feeding oil into working chambers formed by being enclosed by the casing and the pair of rotors in which teeth thereof are meshed to each other; and an oil separating mechanism for separating the oil from compressed gas discharged from the working chambers. The oil-flooded screw compressor drives the pair of rotors at a rotational speed which is low enough not to increase torque for a short amount of time after start-up and accelerates the pair of rotors up to a normal-operation rotational speed after oil discharge. Alternatively, the oil-flooded screw compressor rotates the pair of rotors for a short amount of time after the remaining compressed gas is discharged after a halt, thereby allowing the oil accumulated inside the working chambers to be discharged and ensuring smooth start-up after the halt.
摘要翻译：当在长时间停止之后，在冷空气环境中启动一个充油螺杆压缩机时，由于长时间停留在压缩机的工作室内的油的粘度增加，启动扭矩增加。这需要比正常操作所需的更大的容量的驱动装置。根据本发明的一种充油螺杆式压缩机包括：壳体; 一对转子，每个转子都具有螺纹形槽并容纳在壳体中; 用于旋转地驱动所述一对转子的电动机; 用于控制电动机的控制装置; 供油机构，用于将油输送到由壳体和由其彼此啮合的一对转子形成的工作室; 以及用于将油与从工作室排出的压缩气体分离的油分离机构。充油螺杆式压缩机以一定的转速驱动一对转子，旋转速度足够低，在启动后不会在短时间内增加扭矩，并且在排油后将一对转子加速至正常操作转速。或者，油压螺杆式压缩机在停止后剩余的压缩气体排出之后使一对转子旋转一段时间，从而允许积聚在工作室内的油排出，并确保顺利启动停。

摘要： The difference between internal processes of a power converting apparatus may bring about a heat difference in the apparatus. In the cooling process, it is presumed that the temperature change of the inverter or converter module may be made so great that the power converting apparatus may be less reliable. In order to overcome this shortcoming, the temperature of the internal module is measured and a cooling control of a cooling fan or the like is carried out on the measured result. This cooling control of the cooling fan causes the life of a switching element of the inverter or converter to be longer.
