国产250/50泥浆泵，已取代苏式200/40泥浆泵，广泛应用在地质部门。开始在我队使用时，由于对泥浆质量要求不严，特别是含砂量大，造成密封圈早期磨损、来水不正常、瓷柱塞炸裂等故障。一度影响了生产。我们在提高泥浆质量的同时，为此对设备做了如下改进，效果较好。1．用φ50钢球代替了进、排水伐组件，改进了伐座，伐盖尺寸也做了相应的更动。 Domestic 250/50 mud pump, has replaced the Soviet-style 200/40 mud pump, widely used in the geological sector. Started to use in my team, due to poor quality requirements of the mud, especially the large amount of sand, resulting in early wear seals, water is not normal, porcelain plugs burst and other failures. Once affected the production. We improve the quality of the mud at the same time, to do the following improvements to the device, the effect is better. 1. With φ50 steel ball instead of into, drainage cutting components, improve the cutting block, cutting cover size also made a corresponding change.
