The paper attempts to design and development a new type of hydraulic pump. It is the design of combining the advantages of sucker rod pump and rodless botttom hole pump, without pumping rod,and depends on the hydraulic system on the ground providing the impetus. The paper uses the pump Swabbing Principle to design the main parts of the pump structure and size, analyses and calculates the up down stroke of the piston and the switching process of pump valve, uses the finite element method to analyse the main force summing element and check intensity, and designs a ground hydraulic control system to match it. Considering the need of deep mining, salvage equipment is designed. The design shows that there is feasible and reliable to realize the exploitation underground using the new hydraulic pump. The design idea in this paper enlightens the rodless botttom hole pump production in the future and other similar issues.

Up till now, the main pump types used in CPB are roller pump and centrifugal pump, but these two kinds of pump both have their own disadvantages. When roller pump is used, the blood cells will be destroyed severely and when the pipeline is kinked, air will be transported into body or the conduit will be broken. The function of centrifugal pump is better than that of roller pump, but now, this kind of pumps are all designed for adults, and when the flow rate is low, the function of protecting the blood is not significant.
目前,滚轴泵和离心泵是心肺转流中的常用泵型,但是滚轴泵对血液有形成分的破坏较严重,而且有引起泵管的崩脱和大量气体泵入体内的危险性;离心泵虽然在性能上优于滚轴泵,但目前的离心泵大都是为成人设计的,而且在低流量时在血液破坏方面的优点不明显,此外它们还有一个共同的缺点就是预充量均大,因此两者都不适合在幼婴儿体外循环中应用。

The conveyed medium can't be leaked outside. Thus it will not cause the environmental pollution and human body safety dangerous while exhausting the toxin and flammable or corrosive medium. 5、No electricity. It's safe and reliable while using in the flammable and explore places. 6、It can be soaked in medium. 7、It's convenient to use and reliable to work. Only open or close the gas valve body while starting or stopping. Even if no medium operation or pausing suddenly for long time because of accident matters, the pump will not be damaged caused by this. Once over-loading, the pump will automatically stop and possesses the self-protection function. When the load recovers normally, it also can start automation. 8、Simple structure and less wearing parts. This pump is simple in structure, installation and maintenance. The medium conveyed by the pump will not touch the matched pneumatic valve and coupling lever etc. not like other kinds pumps, the performance will drop down gradually because of the damages of rotor, gear and vane etc. 9、It can transmit the adhesive liquid (the viscosity is below 10000centipoise) 10、 This pump needn't the oil lubricant. Even if idling, it has any influence to the pump. This is a characteristic of this pump.
