影响吸沙泵工作效率的要素有哪些？下面小编就给大家引见一下。
1、泵自身效率是基本的影响.同样工作条件下的泵，效率可能相差15%以上.机械效率的影响主要与设计及制造质量有关.泵选定后，后期管理影响较小，运转工况低于泵的额定工况，泵效低，耗能高.
2、由于过滤缸梗塞、管线进气等缘由形成离心泵抽空及空转.
3、电机效率在运用中根本坚持不变.因而选择一台高效率电机致关重要.水力损失包括水力摩擦和部分阻力损失，泵运转一定时间后，不可防止地形成叶轮及导叶等部件外表磨损，水力损失增大，水力效率降低.
4、泵启动前，员工不注重离心泵启动前的准备工作，暖泵、盘泵等根本操作规程执行不彻底，经常形成泵的气蚀现象，惹起泵噪声大、振动大、泵效低.
5、泵的容积损失又称走漏损失，包括叶轮密封环、级间、轴向力均衡机构三种走漏损失.容积效率的上下不只与设计制造有关，更与后期管理有关，泵连续运转一定时间后，由于各部件之间摩擦，间隙增大，容积效率降低。
以上就是小编为大家引见的影响吸沙泵工作效率的要素，希望大家可以有所理解。
What are the factors that affect the efficiency of sand suction pump? Let's introduce it to you.
1. The effect of mechanical efficiency is mainly related to the design and manufacturing quality. After the pump is selected, the later management has little influence, the operation condition is lower than the rated condition, the pump efficiency is low, and the energy consumption is high
2. Due to filter cylinder block, pipeline intake and other reasons, the formation of centrifugal pump pumping and idling
3. The hydraulic loss includes hydraulic friction and partial resistance loss. After the pump runs for a certain period of time, the surface wear of impeller, guide vane and other parts will inevitably form, the hydraulic loss will increase and the hydraulic efficiency will decrease
4. Before starting the pump, the staff did not pay attention to the preparation work before starting the centrifugal pump, and the basic operating procedures such as warm-up pump and disk pump were not carried out thoroughly, which often led to the cavitation phenomenon of the pump, causing the pump noise, vibration and low pump efficiency
5. The volume loss of pump is also called leakage loss, including impeller sealing ring, interstage and axial force balancing mechanism. The volume efficiency is not only related to the design and manufacture, but also related to the later management. After a certain period of continuous operation of pump, the volume efficiency decreases due to the friction between various parts and the increase of clearance.
The above is a small series for you to introduce the factors affecting the efficiency of sand suction pump, I hope you can understand.
