For The Liquid Delivery Pipe Filter

.tags

Abstract: Many industrial enterprises with gear pump transmission fluid, and before and after the installation of the pump valve to control the pump flow. The disadvantage of this method is a liquid mixed with the iron, sediment and other impurities along with easy to breathe with the liquid pump, gear pump often get stuck, resulting in teeth or gears broken, can lead to coupling to break or burned motor accidents and other unsafe, causing parking and cause economic loss to the enterprise. I plant methanol plant production cycle will occur every one or two screws into the pump of the accident.

Number of industrial enterprises with gear pump transmission fluid, and before and after the installation of the pump valve to control the pump flow. The disadvantage of this method is a liquid mixed with the iron, sediment and other impurities easily be sucked with the pump with liquid, usually within the pump gear jammed, resulting in teeth or gears broken, can lead to coupling to break or burned motor accidents and other unsafe, causing parking and cause economic loss to the enterprise. I plant methanol plant production cycle will occur every one or two screws into the pump of the accident. To this end, we see some information, to design a pipe filter, a better solution to this problem.

Pipe filter structure shown in Figure 1. The working process is:

Start the pump when the liquid is inhaled filter, liquid iron and other impurities by the filter screen of resistance and self-gravity and deposited on the bottom screen, the liquid is can successfully enter the pump through the screen. May from time to time open the hand hole to filter out, clean up the Internet impurities, while another prepared into the filter screen, allowed to continue working to ensure the normal operation of the pump.

In the design, the need to consider is not to substantially increase the channel resistance, the filter shall not generate the vortex. Therefore, the filter housing must be consistent with the pipeline diameter, and must ensure a greater filtering capacity. Screen size should be not less than twice the pipe cross-sectional area, the installation screen size must be based on pipeline have some tilt. As the hole in the hand is easy to form the vortex, therefore, should be made to take net handle cylindrical tube and welding in the bottom of a curved cylinder block, its size and shape should be consistent with the same diameter. In order to screen out easy, quick hand-hole flange structure.

Recent years, I plant in front of all the pumps are installed in the trap, after years of production run, with good effect, was not repeated because of pump failure caused by inhalation of impurities.

The device has a simple structure, easy operation and maintenance, pressure loss, filter capacity, long life, low investment (only about 30 yuan), and so is the liquid delivery equipment to ensure normal operation of the factory a good auxiliary equipment, it is worth promoting.
