查询词典 injection pump

Centrifugal pump flow rate as a pressure change much, while the volume of pump flow rate as a pressure change was small, and the centrifugal pump shaft power decreases with the head of the law to improve the contrary, the volume of the pump shaft power with the pressure increase and increase.

离心泵流量随压力改变很大，而容积泵流量随压力改变却很小，与离心泵的轴功率随扬程提高而减小的规律相反，容积泵的轴功率随压力的提高而增大。

When proceeding pump testing, we collect a good many parameters, and figure out the pump gross head, pump shaft power, NPSH and other parameters. Different units of those parameters are used in different countries, and sometimes the customer asks for the test data of special media. Making a test of every medium of the same pump is not realistic, and the costs will be increase, so we convert the units of the data, and figure out the testing data according to different customer's special requirements. We reduced costs and got good remarks from the corporation through the application of unit conversion technology.

水泵试验时，要采集诸多参数，并且根据这些参数计算出扬程、轴功率、NPSH等数值，不同国家这些参数采用的单位不同，企业必须能够按照客户要求的单位提供试验数据；并且有时客户要求得到水泵在特殊介质下进行试验得出的试验数据，同一台泵在每种介质下都做一遍试验不太现实，而且会提高企业的生产成本，提出将采集的数据进行单位换算，根据不同国家或者客户的特殊要求求出泵的试验数据，在实际应用中节省了试验成本，得到了企业的好评。

The results showed that the method of rubbing the kerf then injection of retrovirus suspension into pancreas could more effectively mark the pancreatic cells than the caudal vein injection and the intraperitoneal injection did in vivo. Furthermore, this study also found that some acinus cells could accept injury stimulus signals to regenerate through resuming mitosis after pancreatic injury.

结果发现在活体条件下，与尾静脉注射及腹腔注射法相比，胰腺伤口涂抹并胰腺内注射反转录病毒的方法能够更有效的标记胰腺细胞；而且，通过对标记细胞的世系追踪研究证明，在胰腺损伤后，胰腺腺泡细胞能够接受损伤信号刺激发生再生。

Can be replaced without needle injection head: no needle injection by the injection of the top head, piston, and a circular ring formed ...

可更换的无针注射头：无针注射头由注射顶端、活塞和一个圆形密封圈组成。。。。

In order to achieve a tradeoff between vectoring and unvectoring state, the proposed parameters of DTN are: Z=3~4, secondary injection flux is about 3%, cavity divergence angle is about 10°, cavity convergence angle is 20°~30°, injection angle of secondary is about 30° by counterflow injection.

为了实现DTN在推力矢量和非推力矢量下都有较好的内流综合性能，所建议的设计参数为：落压比为3~4，引射量为3%，凹腔扩张角为10°左右，收敛角在20°~30°，引射角度为30°逆流引射角(β=30°)。
