Filter Press Installation Location Is High

Filter for the filter is a professional filter to the filter or feed pump. Filter filter dedicated pump classification, wetted part of the material can be divided into: carbon steel, Filter Press glass steel, rubber lined, stainless steel and so on. According to the structure can be divided into vertical and horizontal two.

Filter filter pump is characterized by the use of the beginning of the feed when the flow of large head low, to the latter is a small flow of high head, the higher requirements of the pump. Special attention should be paid to the installation and use of the filter feed pump.

1, the pump inlet and outlet should be installed valve and rubber shock (pipeline compensator) to facilitate maintenance.

2, in the pump installation order, Filter Press the first to install the import and export pipeline, and then fixed anchor bolts to prevent the pipeline when the pump tensile stress, damage to the pump.

3, the export pipeline from the long or high pressure filter pump installation location should be installed at the pump outlet check valve to prevent the export of high pressure water hammer on the pump destructive and reflow caused by the wheel reversal.

4, the pump inlet and outlet pipeline configuration: In order to reduce the pipeline flow resistance, improve the transmission efficiency of the pipeline, Filter Press pump inlet and outlet diameter should be greater than the pump into the export caliber.

5, in order to more intuitive to see the pump running, Filter Press should be installed in the pump outlet pressure gauge, pump outlet in the first valve and pump outlet between the straight line.

6, Filter Press the pump inlet and outlet piping should be set up gravity support system, the pump can not withstand the weight of the pipeline.

7, the return pipe set: filter press pump in normal working condition, when the pump reaches a certain pressure, the flow rate is less than 30% of the rated flow, Filter Press you must open the valve on the return pipe for shunt, so that both can hold the filter The pressure inside, while ensuring that the material within the pump cavity always maintain a certain water content of the liquid state. Filter Press Otherwise, the pressure inside the filter press down, the pump cavity of the material due to pressure, in the role of centrifugal force to dry the material, Filter Press increasing the friction between the material and the pump to shorten the service life of the pump.

Check whether the hydraulic system and other equipment in a good working condition; check the pulp tank level is more than 60%; check the first four rounds of the wheel contact with the track evenly, Filter Press move freely; check the traction chain lubrication and tightness;Filter Press Check whether the two hooks are running synchronously, whether the hook action is flexible and reliable.

Slowly check the feed pressure to the working pressure; Filter Press check the filter cloth on the coal cake is all clean up; to prevent the dry slime clogging filter plate inlet; at any time to observe the filter press and ancillary equipment working conditions.
