Concrete slurry used when the whole process of installation Slurry how to install and use, and when to use specific attention to what the problem? A detailed description: First, check the slurry prior to installation: Before installing the equipment should first check the model, the parameter is correct, whether the parts are complete and intact, technical information and the quality of onboard proof is complete. Slurry pump has been tested at the factory and pilot testing, in order to ensure the equipment is in good working condition, must be installed correctly.
Should not blind operation. The second is the import and export configuration requirements slurry pipeline Same slurry pump suction pipe diameter size should the pump inlet diameter or slightly larger than the diameter of the pump inlet, both to avoid slurry pump cavitation phenomenon, can not form a slurry deposited in the pipeline. Between the pump inlet and suction pipe expansion joints should be located so that dismantling the pump. Diameter and the pump discharge flow rate of the slurry on the nature of the settlement, in general, a discharge outlet diameter should be equal to or slightly larger than the diameter of the pump.
Outlet valve discharge pipe diameter should be the same. Pressure gauge located on the straight pipe between the pump outlet and the first valve. The third is added and the slurry filler to fill the requirements under normal circumstances, slurry pump working pressure 0.5MPa or less at the time, you can use butter or oil to cook cotton packing asbestos packing; When the pump working pressure at 0.5 When MPa or more, slurry pump manufacturer you can use Teflon or carbon fiber packing PTFE packing dip. Filler filler culvert specifications subject to size requirements, adjacent laps filler interface should be mutual mistake 120 degrees. After filling the filler into the cavity, the cap screw by its axial compression, when the shaft relative movement of the filler, the filler is a plastic, it generates a radial force and close contact with the shaft. At the same time, the lubricant impregnated in the filler is extruded to form a film between the contact surfaces. Since the contact state is not particularly uniform, the contact portion has a “boundary lubrication” state, referred to as “bearing” effect; recessed portion is formed without contacting a small tank with a thick film, the non-contact portion and a contact portion composed of not maze of rules to prevent fluid leakage from the role, this is called “labyrinth effect.” This is the packing mechanism. Clearly, a good seal is maintained “bearing effect” and “labyrinth effect.” That is, to maintain proper lubrication and good compression.
