Dry mortar, Weifang Huaneng machinery, dry mortar factory in Shandong Weifang provided by Huaneng machinery. Dry mortar, Weifang Huaneng machinery, dry mortar production equipment Weifang Huaneng Machinery Equipment Institute (www.sdhnyjs.cn) 2014 upgrade been newly introduced dry mortar production line manufacturers Jie Li Machinery Co., Ltd., Zhengzhou engineer pointed out that the density of dry mortar test Shandong dry mortar factory, loose degree methods are strictly regulated, closely packed degree dry mortar equipment, the amount of water is required in advance. In the same way dry mortar production line, different testers test data should not be too much error. Dry mortar density: dry density, bulk density and wet density close. In this case, the aggregate position of the cylinder was especially evident. The solution is: in the middle of an additional aggregate positions in pneumatic lubricator. Apply a layer of butter for the piston rod to prevent corrosion. Failure of the cylinder is prone to leak, the leak has two kinds of leakage and leakage, leakage refers to the cylinder piston assembly badly worn, causing the piston blow-dry mortar before and after the impact speed of movement of the cylinder, causing the switch is not serious place; leakage refers to the ends of the rod in contact with the cylinder seals badly worn and leak, causing the piston rod recovery is slow, even reply is not in place.
