[Asia pump network] filter press pump is characterized by the use of feed flow at the beginning of a large low head, to the late flow of high-lift small, higher on the pump. Pay attention to the installation and use of filter press feed pump. YL filter press pump installation should pay attention to what the problem? Filter press pump installation points: 1. The pump import and export should be installed valves and rubber seismic section (pipe compensator) to facilitate overhaul. 2. In the pump installation order, first install the import and export pipelines, and then the anchor bolts to prevent the connecting pipe when the pump tensile stress, damage to the pump. 3. The outlet pipe is long or the filter press pump is installed at a high position. A check valve should be installed at the outlet of the pump to prevent the high pressure water hammer at outlet from destroying the pump and reversing the impeller caused by the backflow. 4. Pump import and export pipeline configuration: In order to reduce the flow resistance of the pipeline, improve the pipeline transmission efficiency, pump inlet and outlet diameter should be greater than the pump inlet and outlet diameter. 5. In order to more intuitively see the operation of the pump, the pressure gauge should be installed at the outlet of the pump, which is located on the straight line between the first valve and the outlet of the pump. 6. Pump inlet and outlet piping should be set up gravity support system, the pump can not afford the weight of the pipeline. 7. Return pipe settings: filter press pump in normal working condition, when the pump reaches a certain pressure, the flow is less than 30% of the rated flow, you must open the return valve on the valve for shunt, so that both can stabilize the filter press Within the pressure, but also to ensure that the material inside the pump always maintain a certain moisture content of the liquid state. Otherwise, the pressure in the filter press is decreased, and the material in the pump cavity will be dried under the action of centrifugal force due to the pressure in the pump cavity, which increases the friction between the material and the pump and shortens the service life of the pump.
