商品详细描述






细沙回收泵压滤机入料泵的好坏也直接影响到工业出产的正常停止,所以泵是化工、石油局部的关键设备之一。另外在化工、石油局部出产中的液体比拟特别,有的液体易挥发、或有毒;有的为强腐蚀或高粘性的;有的请求在高温、高压或低温、低压下停止运送等。因此,这些液体就相应地需求一细沙回收泵特别泵来满足请求,并且请求的数量也很大。细沙回收泵




The quality of the feed pump of the filter press also directly affects the normal stop of the industrial productio the pump is one of the key equipment in the chemical industry and petroleum industry. In addition, the liquid produced in the local production of chemical industry and petroleum is relatively special, some of which are volatile, flammable, explosive or toxic; some are strongly corrosive or highly viscous; some request to stop transportation under high temperature, high pressure or low temperature, low 


离心泵启动前需注意的问题

化工离心泵是一种叶片泵,依靠旋转的叶轮在旋转过程中,由于叶片和液体的相互作用,叶片将机械能传给液体,使液体的压力能增加,达到输送液体的目的。离心泵工作有以下特点:

   1、工作稳定,输送连续,流量和压力无脉动。细沙回收泵

   2、离心泵在一定转速下所产生的扬程有一限定值。工作点流量和轴功率取决于与泵连接的装置系统的情况(位差、压力差和管路损细沙回收泵失)。扬程随流量而改变。一般无自吸能力,需要将泵先灌满液体或将管路抽成真空后才能开始工作。细沙回收泵




   3、离心泵在排出管路阀门关闭状态下启动,旋涡泵和轴流泵在阀门全开状态下启动,以减少启动功率。

   化工离心泵在启动时,泵的出口管路内还没水,因此还不存在管路阻力和提升高度阻力,在离心泵启动后,离心泵扬程很低,流量很大,此时泵电机(轴功率)输出很大(据泵性能曲线),很容易超载,就会使泵的电机及线路损坏,因此启动时要关闭出口阀,才能使泵正常运行。如果用轴流式的水泵就情况相反了,必须是开阀启动,此时电机的功率小短时间内由于没有阻力,会偏大流量运转,常常出现泵振动、噪声,甚至电机超负荷运转,将电机烧毁。关闭出口阀,等于人为设置管阻压力,随泵正常运转后,缓慢启动阀门,让泵沿其性能曲线规律逐步正常工作。



the parameter values respectively, and draw a curve to express them. These curves are called the characteristic curve of the pump. Each pump has a specific characteristic curve, which is provided by the pump manufact细沙回收泵urer. Generally, the characteristic curve given by the factory also indicates the recommended performance section, which is called the working range of the pump. The actual working point of the pump is determined by the intersection of the curve of the pump and the device characteristic curve of the pump. When selectin
