机喷设备发展史及简介
Development History and Brief Introduction of Machine Injection Equipment
一)单向阀式柱塞泵
One-way valve piston pump
2016年上半年,我与德国大象的品质总监鲁茨先生也谈及了灰浆机,世界第一台灰浆机采用的是双缸单向阀式柱塞泵,该机型缸体及活塞耐磨性好,但单向阀容易卡阻而引发严重内泄。
In the first half of 2016, I also talked with Mr. Rutz, the quality director of German elephant, about the mortar machine. The world's first mortar machine is a two-cylinder one-way valve piston pump. The cylinder block and piston of this type have good wear resistance, but the one-way valve is easy to jam and cause serious internal leakage.
1.大流量更易引发更严重内泄,限制了单向阀柱塞泵的工作能力;
1. Large flow rate is more likely to cause more serious internal leakage, which limits the working capacity of one-way valve plunger pump.
2.内泄也导致工作压力难以达到理想值,压力高时,内泄也更严重;
2. Internal leakage also makes it difficult to achieve the ideal working pressure. When the pressure is high, internal leakage is more serious.
3.内泄不但影响工作流量及压力,同时也会使输送中的砂浆产生往复式振荡,导致泌水式离析;
3. Internal leakage not only affects workflow and pressure, but also causes reciprocating oscillation of mortar during transportation, leading to bleeding segregation.
4.砂浆粘度大时内泄更为严重,针对石膏砂浆的粘性更是难行。
4. The internal leakage of mortar is more serious when its viscosity is high, and it is more difficult to deal with the viscosity of gypsum mortar.
以上致使柱塞式灰浆机流量相对较小,有脉冲,对输送砂浆也有破性。PM公司投入大量精力进行改善,终难突破(后来三一也花费了大量精力研究单向阀式柱塞泵,也宣告失败),后推出螺杆式灰浆机。
As a result, the flow rate of the plunger mortar machine is relatively small, there are impulses, and it also breaks the conveying mortar. PM company invested a lot of energy to improve, but it was difficult to break through (Sany also spent a lot of energy to study one-way valve plunger pump, also declared failure), and then launched screw mortar machine.
