  • Six core factors contributing to the rise in copper prices today1. Global copper mine supply continues to contract, intensifying mining and metallurgical conflictsGlobal copper mining capacity gap widens:Major copper mine production declines: Codelco in Chile (the world's largest copper mine) will s
  • Why does a submersible pump not release water when drainingReason:1. Poor connection of water pipe interface: The water pipe connected to the outlet of the submersible pump is not connected properly, or the water pipe is damaged, which can cause the submersible pump to not discharge water when place
  • The advantages and disadvantages of using aluminum wire and copper wire for water pump motors are as follows:Advantages and disadvantages of aluminum wire motorsAdvantages:Lower price: Aluminum is relatively cheaper than copper, so the cost of using aluminum wire motors is lower.Lightweight: The low
  • The difference between external and internal machine seals1. Appearance2. Installation locationExternal mechanical seal refers to a mechanical seal installed outside the shaft end of the equipment, usually located outside the equipment and connected to the main body of the equipment through flanges
  • Reasons and solutions for oil leakage in submersible pumps1、 Reasons for oil leakageMechanical seal damageMechanical seals are key components in preventing oil leakage. If the seals age, wear, or are installed improperly, it can lead to oil leakage.Reason: Long term operation, impurities in water qu
  • What causes the submersible pump to trip when powered on1. Electrical malfunctionShort circuit: Water ingress into the internal coils, cables, or junction boxes of the pump body can cause a short circuit. Use a multi-meter to measure the winding resistance (normally several ohms to tens of ohms, if
  • The reason for the sudden decrease in water output of the submersible pump1. Impeller or pump body flow channel blockageReason: Impurities (such as water grass, sediment) block the impeller or pump body flow channel, resulting in a decrease in flow rate and head. ‌Solution: Disassemble the pump and
  • Classification and characteristics of submersible motors:Dry submersible motor: The interior of the dry submersible motor is filled with air, and the shaft extension end is equipped with mechanical sealing devices and rubber oil seals, which can prevent moisture and dampness from entering the interi
  • Methods to prevent damage to water pumps caused by prolonged disuseDisassemble and storeIf disassembly is convenient, the water pump and pipeline can be removed and cleaned thoroughly.Check the bearingsCheck the ball bearings, and replace them if the inner and outer sleeves are worn, loose, the ball
  • Reasons for the pump body to heat up when using the water pump:‌1. Bearing damage: Bearing damage will increase friction, causing the pump body to heat up. Insufficient or excessive lubricating oil (grease) in the bearing, poor quality, mud, iron filings and other debris, and bearing clearance that
