影响压滤机专用时间的因素如下:
1、浆料粘度。浆料越细越粘,则过滤速度越慢,反之亦然。
2、压滤机专用压力与流量。这个好理解,流量高压力大则过渡速度也快。但要有限度,一般来说,入料压力不要超过0.6MPa,至于流量,要视压滤机的过滤面积而定。
3、滤布。滤布厚实,压滤机专用,则过滤速度慢。
总之,终决定过滤速度应当是料本身。因为浆料泵和滤布可以合理选型。为了提高浆料过滤速度,除合理选择泵和滤布以外,还可以考虑在浆料中加入絮凝剂

压滤机专用流量扬程选择
在设计压滤机专用泵时参考了国内主流的压滤机设备,并结合了多年来客户的使用情况,设定了几种常用的压滤机泵型,其流量扬程能够满足市场通用的各种型号压滤机。
在不同型号间选择时,应遵循选大不选小原则,因为型号大的泵初始流量大,有利于压滤机初期快速均匀布料,提高生产效率,防止物料分布不均造成后期压力不稳定对设备造成影响。
另外选择泵的压滤机专用压力时要看扬程高点的压力,此时的压力为压滤机压榨期的泵的工作压力,也是泵输出的大压力值。
压滤机专用Selection of flow head for feed pump of filter press
In the design of the special pump for filter press, the domestic mainstream filter press equipment was culted,压滤机专用柱塞泵, and combined with the use of customers for many years, several common types of filter press pump were set up, whose flow head can meet the needs of various types of filter press commonly used in the market.
When choosing different models, we should follow the principle of choosing big ones instead of ***all ones, because the initial flow rate of large pumps is large, which is beneficial to the rapid and uniform distribution of materials in the initial stage of filter press, to improve production efficiency, and to prevent the influence of unstable pressure in the later stage caused by uneven distribution of materials on the equipment.
In addition, when choosing the pressure of the pump, it depends on the pressure of the highest point of the lift. At this time, the pressure is the working pressure of the pump during the press period of the filter press, and also the maximum pressure value of the output of the pump.
压滤机专用在新叶轮买来后,先要检查叶轮的外观,是否平整、是否有砂眼、裂痕等,确保新叶轮无质量问题的。其次要进行动平衡实验,保证叶轮更换后不会出现转偏,压滤机专用进料泵,泵不会出现震动严重。由于客户一般都不会配备***的实验设备,所以的叶轮配件在出厂时已经做过平衡实验,保证客户装上后能正常运行。
更换压滤机专用叶轮首先要拆泵,卸下损坏的老叶轮。这里应该注意的一点是,污泥压滤机专用泵,压滤机专用叶轮固定在泵轴上采用的反丝,即与水泵转动的方向相反,这样的好处是越转越紧,拆卸和安装叶轮的时候一定要按照正确的方向操作。
