活塞泵

The membrane isolation pumps is one kind of hydromass transportation hydraulic system,can reduce the cartage expense greatly,but indirectly brings the huge social efficiency,safe reliable,the work rate is high,may not stop nearly carries on the whole year to transport,does not have the material to lose nearly,the easy automatic control,to be advantageous for the maintenance management The hydraulic pressure diaphragm pump is one kind of fill domestic diaphragm pump which we develops in high-pressured,the small curr ent capacity pulp transportation aspect blank pumps plants,it and the common diaphragm pump main difference is:Has substituted for the crank connecting rod,the reduction gear using the hydraulic pump and so on aseries of equipments direct drive piston motion,this causes its structure is greatly the simplification,the cost drops greatly;When at the same time also requests the piston the commutation confidential assurance extremely accurately,but must realize this point theoretically and all has the very great difficulty in fact.

膜隔离泵就是一种浆体输送的液压系统，能大大降低运输费用，可间接带来巨大的社会效益，安全可靠，作业率高，几乎可不停地进行全年输送，几乎没有物料损耗，易于自动控制，便于维护管理。液压隔膜泵是我们开发的一种填补国内隔膜泵在高压、小流量矿浆输送方面空白的泵种，它与一般的主要区别是：利用液压泵取代了曲柄连杆、减速器等一系列装置直接驱动活塞运动，这使其结构大为简化，成本大大下降；但同时也要求活塞的换向时机要把握得非常准确，而要实现这一点理论上和实际上都存在很大难度。

Caused by the brake disc brake on back wheel should not have four kinds of spaces possible: First, the foot brake 5 exhaust inlets, high pressure gas instinct Pai people the atmosphere, caused by gas-liquid master cylinder should not spring back to place, cause the system Oil will move the brake disc brake wheel cylinder piston top dead can not come back to places; are gas-liquid two disc brake master cylinder to the tubing plug, resulting in brake wheel cylinder piston can not come back to places; are three master cylinder of gas-liquid Can not spring back to their own spaces, brake fluid under high pressure gas, liquid should not return to the master cylinder reservoir chamber, resulting in brake wheel cylinder piston can not come back to places; are four wheel disc brake piston brake system because of moving fluid dirty or rusty Pistons Can not Back-bit card dead.

造成盘式制动器上的制动分泵不能回位有4种可能：一是脚制动阀5的排气口堵塞，高压气体本能排人大气，造成气液总泵的弹簧不能回位，导致制动油将盘式制动器的制动分泵活塞顶死而不能回位；二是气液总泵至盘式制动器的油管堵塞，造成制动分泵活塞不能回位；三是气液总泵的弹簧本身不能回位，制动液在高压气体作用下，不能回到气液总泵的储油室，从而造成制动分泵活塞不能回位；四是盘式制动器制动分泵活塞由于制动液太脏或活塞生锈卡死而不能回位。

Caused by disc brake on the brake Wheel Cylinder could not return to places 4 possible: First, 5 foot brake valve exhaust port blocking, high-pressure gas instinct platoon atmosphere, caused by gas-liquid master cylinder of the spring could not return to place, resulting in the system move oil, brake disc brake Wheel Cylinder Piston top dead and could not return to places; second is to the disc brake master cylinder gas-liquid pipeline blockage, resulting in brake Cylinder piston can not return to place; third master cylinder of the gas-liquid Spring itself can not return to position, brake fluid under high pressure gas can not return Axial pump to gas-liquid master cylinder reservoir chamber, resulting in brake Cylinder piston can not return to places; Fourth Wheel Cylinder piston disc brake system, due to moving fluid dirty or rusty card dead and can not return to the piston position.

On the research of reciprocating pump,if the linear motor-driven piston or reciprocating plunger being applied,the structure of reciprocating pump will be greatly simplified.And the movement of the piston can be changed so that the flow of pump is constant;Meanwhile easily to achieve automatic control,and when using the intelligent control system,easily to implement automated production.

在往复泵的研究中，如果采用直线电机直接驱动做往复运动的活塞或柱塞，那么往复泵的结构将大为简化，泵总体结构紧凑，系统效率高；并且可以通过改变活塞的运动规律，使泵的流量恒定；同时便于实现自动化控制，若采用智能化控制系统易于实现自动化生产。

Mud is a common type or plunger-type piston, driven by the motive power of the crankshaft rotary pump, crankshaft driven through the crosshead and then the plunger in the pump cylinder piston or reciprocating motion to do.

常用的 泥浆泵是活塞式或柱塞式的﹐由动力机带动泵的曲轴回转﹐曲轴通过十字头再带动活塞或柱塞在泵缸中做往復运动。

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.

所以抽送有毒、易挥发或腐蚀性介质时，不会造成环境污染和危害人身安全； 5、不必用电，在易燃、易爆场所使用安全可靠 6、可以浸没在介质中工作 7、使用方便、工作可靠、开停只需简单地打开和关闭气体阀门，即使由于意外情况而长时间无介质运行或突然停机，泵也不会因此而损坏，一旦超负荷，泵会自动地停机，具有自我保护性能，当负荷恢复正常后，又能自动启动运行； 8、结构简单、易损件少，该泵结构简单，安装、维修方便，泵输送的介质不会接触到配气阀，联杆等运动部件，不像其他类型的泵因转子、活塞、齿轮、叶片等部件的磨损而使性能逐步下降； 9、可输送较粘的液体（粘度在1万博以下）； 10、本泵无须用油润滑，即使空转，对泵也无任何影响，这是该泵一大特点
