The copper price has seen a sharp rally, driven by three interlinked factors: persistent supply-side pressure, a new growth engine in demand, and a convergence of financial and policy expectations.Core Driving Factors1. Tightened Supply Frequent production accidents in global copper mines (e.g., Chi

Maintenance of Deep Well Pumps(1) Daily Maintenance (Daily / Weekly)Operation status monitoringKey parameter records: flow rate, pressure (investigate deviations exceeding ±5%, possibly due to impeller wear or pipeline blockage), motor current (shut down if exceeding 10% of rated value);Abnormal jud

Installation of deep well pump:（1） Preparation before installation:Well body and equipment verificationDiameter verification: The actual diameter of the well should be at least 50mm larger than the diameter of the pump body (if a 100mm pump body is selected, the diameter should be ≥ 150mm), and a di

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
