Industrial pump priority development of the key products are: for the national key construction services supporting products;Compared with foreign countries, RY oil pump in China is still in a backward position or is still a blank pump products in Chi
The Chinese government has listed the environmental protection industry as a priority area for development. China's water pollution control market has huge potential. China will multiply the construction of urban sewage and industrial sewage treatment
A few days ago, Botou City product quality supervision and inspection pre-revised agricultural self-priming pump hazardous substance limit and test method standard project is the Ministry of Education
Recently, a new type of self-priming oil pump with permanent magnet bearing has been successfully developed in Jiangsu University. Due to the rotor and no mechanical contact and friction, low vibration and equipment noise of the pump, the model test m
1. The cavitation phenomenon of centrifugal pump a. The cavitation phenomenon of centrifugal pump refers to the partial vaporization of the transported liquid because the saturated vapor pressure at the conveying temperature is equal to or lower than
高压力多级柴油泵的分类及性能
齿轮柴油泵轴承、壳体、安全阀、轴封的介绍
当各种防爆柴油泵选型的必须是正确的,合理的,并没有太多的实际工况之间的差异,防爆柴油泵的选择应根据所需流量,介质的比例和实际需要电梯选择适应柴油泵爆款。 防爆柴油泵
(二)产品的市场占有率 泊头油泵厂的 柴油泵 虽然起步较早,但是受计划体制的影响,生产规模的扩展并不快。1980年以前生产规模一直在2000台以下,生产的 柴油抽油泵 以组合泵为主
盛龙在讲座中提到:科技创新将是决定机械工业持续发展能力的关键。丁骐也认为:现在成都本地机械制造业要做的,就是加强行业整合,拓宽资金渠道,减少恶性竞争,使行业处于健
叶轮安装在泵壳内,并紧固在泵轴上,泵轴由电机直接带动。泵壳中央有一液体吸入与吸入管连接。液体经底阀和吸入管进入泵内。泵壳上的液体排出口与排出管连接。 在 柴油泵 启动
主要部件有叶轮、泵壳和轴封装置。 1 叶轮 叶轮的作用是将原动机的机械能直接传给液体,以增加液体的静压能和动能主要增加静压能。 叶轮一般有6~12片后弯叶片。 开式叶轮在叶片两
各类柴油输送泵的型号已实现了标准化,并依照用途的不同实现了系列化,以一个或几个汉语拼音字母作为系列代号。在每一系列内,又有各种不同的规格。我国泵类产品型号的编制由
1、多级柴油泵装配前的准备 (1)各种工具及多级柴油泵零部件螺栓螺母摆放好。 (2)仔细阅读多级柴油泵的产品说明书,了解多级柴油泵的装配顺序及方法。 (3)把多级柴油泵的装
高压柴油泵是指带有多个叶轮串联安装、流量串联流动的离心泵,所以称为高压柴油泵。 从本质上讲,单级离心泵的扬程是由叶轮结构类型和圆周速度决定的。如果转速因为其他边界条
