W型往复式真空泵是制砖(瓦)真空挤泥机的主要真空设备之一,而它的滤清器的性能对整个机组的正常使用有着重要影响.为此,我们通过实践,使用海绵芯式滤清器(以下简称——海绵滤清器)效果较好.1 滤清器的作用我们知道,真空工艺就是利用一定的抽气设备,在制砖(瓦)搅拌挤出成型过程中.抽取泥料中的空气,从而使坯体强度增大、密实度提高和产品的综合性能得到显著改善.那么,在实现“真空”过程中,真空泵与真空箱之间的抽气管道上要设置滤清器,其作用是过滤被抽取空气中的细颗粒泥料和少量的冷凝水,以达到保证真空泵正常运转和延长使用寿命的目的.2滤清器的结构
The W-type reciprocating vacuum pump is one of the main vacuum equipments of the brick (wattage) vacuum squeezer, and the performance of its filter has an important influence on the normal use of the entire unit. For this reason, we use the sponge core through practice. The filter (hereinafter referred to as - the sponge filter) has a good effect. 1 The function of the filter We know that the vacuum process is the use of a certain suction equipment, in the process of making bricks (tiles) during the mixing extrusion process. Extraction of air in the mud, so that the increase in the strength of the green body, improve the compactness and the overall performance of the product has been significantly improved. Then, in the realization of the “vacuum” process, the suction pipe between the vacuum pump and the vacuum box should be set on the filter Cleaner, its role is to filter the air in the fine-grained mud and a small amount of condensate in order to ensure the normal operation of the vacuum pump and to extend the life of the purpose. 2 filter structure
