Agricultural Centrifugal Pump Maintenance and Troubleshooting

Agricultural centrifugal pump working conditions are generally poor, in the course of work by environmental conditions, mechanical vibration and other factors, the technical status of different changes. Pump maintenance is the unit itself in the normal state of technology has not been destroyed before the fastening, adjustment should be tightened, adjusted; and a few locusts stop? End? H???? Often observed Various instrumentation monitoring devices; timely detection of problems will be troubleshooting, so that the crew is always in good technical condition. The only way to extend the service life of the pump unit to ensure that the unit work in high quality, efficiency.
? Maintenance during operation (1) Centrifugal pump maintenance should pay attention to the sound and vibration of the pump at any time. If it is found that the sound of the unit is not normal or there is a large vibration, stop it immediately, check the cause and eliminate it in time to prevent the accident from happening .
(2) centrifugal pump maintenance should always pay attention to the location of a variety of instrument pointer, if there is a sudden change, you should check the reason. Usually a sudden increase in vacuum gauge readings, it is possible to sink into the water pool is too low or the water pipe blocked by debris. The sudden drop in pressure gauge readings is most likely caused by a decrease in engine speed or air in the pump being drawn in. Find the reason, you should try to eliminate.
(3) centrifugal pump maintenance should always check the bearing temperature and lubrication conditions. Bearings lubricated with oil ring, should pay attention to whether the oil ring is flexible, bearing oil should be added in time to maintain the appropriate amount of oil, too much or too little fuel can cause fever. Oil to? [Clean, general sliding bearings should be changed every 200h-300h after oil, but at least once every six months for oil change; Rolling bearings should be checked after each operation 1 500h? (4) centrifugal pump maintenance should pay attention to the pump stuffing box is normal, the filler must be continuous water dripping (usually about 30 drops per minute>, too much too little should be adjusted gland screw so that The packing is just right.
(5) Centrifugal pump maintenance should always be checked? Private 苈 ⑻ ⑻ 盍 Shrimp 扔 shaped 蘼 ┢ 窒 螅 缏 缏 ┢? (6) Centrifugal pump maintenance should always check whether there is floating near the water inlet pipe , To prevent the water inlet blocked. When the inlet water level is too low, it should stop running; otherwise, the inlet will produce vortex, the air inhaled pump. If the water level in the influent pool is low, but the pumping can be maintained, when a drought is urgently needed, a piece of wood can be covered on the water surface where the eddy current is generated to prevent the air from entering the pump to facilitate the work of the water pump.
(7) Belt-driven units should be kept with a face clean and dry, shiny surface, the surface can be cleaned with grease and dirt on the oil, to prevent slippage, and keep the belt tightness.
(8) Centrifugal Pumps When pumping water on a multi-silt river, it should be noted that the sediment concentration should not exceed 7% in general; otherwise, the pump efficiency will be significantly reduced, the flow rate will decrease, and the over-current part will be easily worn.
I plant centrifugal pump series ISG vertical single-stage single-suction centrifugal pump, ISW horizontal single-stage single suction centrifugal pump, S, SH single-stage double suction centrifugal pump, SOW, SOL series single-stage double suction centrifugal pump , ZX series self-priming centrifugal pumps, WFB-type seal-free self-priming centrifugal pumps.

Iron Oxide

Iron oxide pigment is chemical compounds composed with formula Fe3O3 . Synthetic iron oxide is the most common colorant in concrete and cement paint. Iron oxide is an important inorganic color pigment, chemical stability, strong color strength, fine dispersion and excellent light resistance, weather resistance.

Major Features:

1)Brilliantly colored powder. Eye-pleasing and durable.
2) Strong coloring power, excellent coverage.
3) Light permanency and weatherability.
4) 6~7 grade resistance to oxidation and light permeability, 4~5 grade resistance to basic materials.


1) Used in many types of paints, including anti-rust paint, water-soluble indoor/outdoor paints and oil-based paints.
2) Used for dyeing construction materials, such as mosaic bricks, for concrete bricks, pavement, colorful tiles, roofing tiles and man-made marble. Colors for ceramic body.
3) Used in paper industry, esp. rice paper.
4) Used for surface coloration of plastic epoxy floor, color for pitch.
5) Used as a more fade-resistant dye for plastics.
6) Used as pigment for cosmetic.
7) Used as coloring Sugar-coat for medicine tablets.
