The present invention shrinks the tissue in the heart (10) by selectively heating infarcted scar in order to reduce the size of the surface of the infarcted scar, make the soft part of the scar tissue become rigid, reduce the wall tension of shrinking the ventricle, and increase the total pump efficiency of the infarcted heart (10) by removing ventricle aneurism.

本发明通过有选择地加热梗塞瘢痕，收缩心脏（10）中的组织以缩小瘢痕组织表面积（18）的大小、使瘢痕组织的松软部分变硬、减少心室收缩的壁张力，并通过消除心室动脉瘤来增加梗塞心脏（10）总泵送效率。

A process for treating the sludge generated by alumina sewage treating system incldues such steps as pumping the alumina sewage in sand depositing pool then in depositing pool, mixing the bottom sludge, the sewage from sand-water separator, and the regenerated water from filter to obtain backflush water, heating in desilicating heater, washing the secondary red mud to recover Na2O and Al2O3, anjd returning the washing liquid containing Na2O and Al2O3 back to the flow of production of alumina.

本发明公开了一种氧化铝废水处理系统的污泥处置新工艺，它将氧化铝废水先进入沉砂池中进行沉砂处理后才进入沉淀池中，将虹吸泥机从沉淀池中吸出的底流污泥和砂水分离器分离出的污水以及将部分经过滤器过滤后所得的再生水作为反冲洗水一起通过污泥泵送到脱硅加热器中加热得污泥热水，然后将污泥热水用于二赤泥洗涤沉降，以回收赤泥附着的Na2O和Al2O3，将洗涤赤泥后含有Na2O和Al2O3的洗液送到氧化铝生产流程中重新使用。

The system of fueling pipeline ,in particular, the branch form pipeline system with pump deliver,one side, the form of pipeline is multiplicity,on the other hand, the working state is changefully,so,the working state of the system must be adjusted and controled, the paper contraposes the system, investigating the method of adjusting and control,introducing several pressuered-control valv

注油管路系统，特别是多分支的泵送管路系统，一方面管路结构形式多样，另一方面工作状态多变，因此，在系统工作中均需对工况进行调节与控制。

As part of its approach, Colfax provided support for the pumping process, offering insight and information on speed regulations and startup processes.

作为方案的一部分，科尔法为泵送系统提供了多种支持，包括时速规范与启动进程。

It can be used not only inconcrete pumping, but also in plasm supply and concrete shooting.It works nicely in mining mill filling.

本泵不仅可以用于泵送混凝土，而且可以用于注浆、混凝土喷射等场合，它是一种工作性能良好的矿井填充设备。

It can be used not only in concrete pumping, but also in plasm supply and concrete shooting.

本泵不仅可以用于泵送混凝土，而且可以用于注浆、混凝土喷射等场合。

Construction of concrete pump is used to enhance the height of 30 1 300M, the thickness of more than 0.5M mass concrete, with savings of manpower, material and time is short, high efficiency, fast and convenient features, concrete pumping concrete on the mobility of higher, the need to control slump at 12-16 cm between the silo slipform request the initial setting of concrete, final setting time control at 2 hours and 20 minutes, 3 hours and 30 minutes or so, stick to prevent mold, in favor of Waterloo or.

混凝土输送泵施工，是用于提升高度30一300M，厚度0.5M以上的大体积混凝土，具有节省人力、物力、时间短、效率高、快捷方便的特点，但泵送混凝土对混凝土的流动性要求较高，坍落度需要控制在12—16厘米之间，筒仓滑模要求混凝土的初凝、终凝时间控制在2小时20分、3小时30分左右，可防止粘模，利于滑升。

Cited Pistons pull vent valve 10-valve piston cited the role of pulling out are seized cylinder piston rod, when its mild in China emerged after the main hydraulic cylinder rod cavity and there is no cavity under the pressure dropped, so that the main hydraulic cylinder in motion the process of increasing resistance to the main pump to increase the load, resulting in engine speed when pumping declining situation.

3活塞引拔阀内泄活塞引拔阀10的作用是拉出检缸活塞杆，当其出现轻度内泄后，主液压缸无杆腔和有杆腔的压差下降，使主液压缸动作过程中阻力增加，使主泵负荷加大，导致泵送时出现发动机转速下降的现象。

"The delivery rate of two-cylinder piston pump with the patented concrete valve can be adjusted from 2 cubic meters/h to a maximum of 34 cubic meters /h, for pumping pressures of up to 65 Bar ."

双缸活塞泵装有取得专利的混凝土阀，其输送速度的范围从2立方米/小时到34立方米/小时，泵送压力可达65巴。

The high vacuum created by the pump permits rapid self priming at the maximum height made possible by the physical characteristics of the pumped liquid (temperature, vapour pressure, viscosity etc).

当泵送液体的物理特性到达极值时，泵浦的高真空装置仍能快速的完成自吸。
