What to pay attention to in the operation of low-pressure gear oil pumps
Low-pressure gear pumps must use explosion-proof gear pumps when transporting diesel. This requires gear pump gears to be made of copper. According to the gear pump industry standard, gear pump gears should be tin bronze when choosing copper. Tin bronze is The non-ferrous metal alloy with the smallest casting shrinkage. The low-pressure gear oil pump is used to produce castings with complex shapes, clear contours and low air tightness requirements. Tin bronze is very resistant to corrosion in the atmosphere, sea water, fresh water and steam, and is widely used in steam boilers. And ship parts.Phosphorous tin bronze has good mechanical properties and can be used as wear-resistant parts and elastic parts of high-precision work machine.Lead-containing tin bronze is often used as wear-resistant parts and sliding bearings. Tin bronze is a material with excellent wear resistance and long mechanical life. It is widely used in various wear-resistant parts and sliding bearings, gear pumps, and screw pumps. In other industries, it is guaranteed that the gears of low-pressure gear oil pumps will not generate sparks during use, thereby ensuring the safety of gear pumps when transporting flammable and explosive media. Low-pressure gear oil pumps should use mechanical seals when transporting diesel or low-viscosity media. Do not use conventional skeleton oil seals or packing seals. Ensure that low-pressure gear oil pumps do not leak when conveying low-viscosity or flammable and explosive media. The pump is safe to use. In addition, when the low-pressure gear oil pump is transporting diesel or similar low-viscosity medium, the thrust plates that contact the two sides of the gear pump gear should also be made of wear-resistant materials such as tin bronze or alloy steel to extend the service life of the gear pump.
