单螺杆泵的起动
单螺杆泵应在 吸排停止阀全开的情况下起动,以防过载或吸空。
单螺杆泵虽然具有干吸能力,但要防止其干转,以免擦伤工作面。如果泵需要在油温很低或粘度很高的条件下起动,应先将吸排阀和旁通阀全开,再起动。泵起动时的负荷,直到原动机达到额定转速时,再将旁通阀关闭。当旁通阀开启时,液体在有节流的情况下在泵中不断循环流动,循环的油量越多,时间越长,液体的发热温度越高,甚至会使泵因高温变形,导致损坏,这必须引起注意。
G型螺杆泵产品概述
G type screw pump product overview
单螺杆泵在发达***已广泛使用,国外多数称单螺杆泵为“莫诺泵”《MONOPUMPS》,德国称为“偏心转子泵”。由于其优良的性能,近年来在国内的应用范围也在迅速扩大。
1Single screw pump has been widely used in developed countries, most of the foreign said single screw pump as "Monod pump" "MONOPUMPS", Germany called "eccentric rotor pump". Because of its excellent performance, in recent years, the scope of application in China is also rapidly expanding.
它的特点是对介质的适应性强、流量平稳、压力脉动动小、自吸能力高,这是其它任何泵种所不能替代的。
It is characterized by a strong adaptability to the media, ***ooth flow, pressure pulsation, 1***all, high self absorption capacity, which is not a substitute for any other pump.
