[发明内容] [SUMMARY]

本发明的目的是提供一种往复泵隔膜型液力端流道结构,它可以在输送浆体的过程中更有效地减少浆体的沉积和堵塞。 Object of the present invention is to provide a reciprocating diaphragm pump fluid end flow passage structure, it can be more effective in reducing the deposition and clogging in the process of conveying the slurry in the slurry.

本发明通过下述技术方案实现的: 一种能够输送浆体的往复泵隔膜型液力端流道,包括吸入和排出流道孔,缸盖底部的吸入流道出口为月牙形流道结构,其特征在于:所述的流道出口由两个120°的月牙形流道组成的月牙形流道结构,其中一个为较大的120°月牙形流道, The present invention is achieved by the following technical solution: a suction channel outlet capable of transporting the slurry reciprocating pump diaphragm type fluid end flow passage, the flow passage including a suction and discharge hole, the bottom of the cylinder head is crescent shaped flow channel structure, wherein: a crescent-shaped flow channel structure according to a crescent-shaped channel outlet flow path consisting of two 120 °, wherein 120 ° of a larger crescent-shaped flow passage,

另一个为较小的120。 Another 120 smaller. 月牙形流道,所述月牙形流道分别由两个偏心圆 Crescent-shaped flow channel, the flow channel of two crescent-shaped eccentric respectively

构成,较大的月牙形流道圆的半径比较小的月牙形流道圆的半径大, Configuration, the crescent-shaped large radius circle flow passage is relatively small radius circle large crescent-shaped flow passage,

3较小的120°月牙形流道位于较大的120。 3 small crescent-shaped 120 ° flow path 120 located in the larger. 月牙形流道之上,并靠近隔膜。 Crescent-shaped flow path above and close to the diaphragm. 浆体由吸入阀组流入缸盖底部流道孔后,经过两个12(T月牙形的流道到达隔膜端,之后由缸盖顶部流道孔流入排出阀组。 After the cylinder head bottom flow passage flows into the slurry by the suction valve hole, two through 12 (the crescent-shaped flow passage T reaches the end of the separator, then by a top channel head discharge orifice into the valve.

本发明的有益效果是,在输送浆体时,向下沉积的浆体在流道底部120°的范围内都可以受到月牙形流道内流动浆体的冲刷,从而解决大部分的沉积问题,且月牙形流道由两个偏心的圆构成,工艺性好, 容易加工制造。 Advantageous effects of the present invention is that, during transportation slurry, slurry is deposited downwardly in the range of 120 ° of the bottom flow passage can be washed in the slurry flow crescent flow passage, so as to solve most of the problems of deposition, and crescent-shaped flow channel is formed by two eccentric circles, manufacturability, and easy manufacturing.
