  • How to deal with insufficient lift of deep well submersible pump?Each failure may not be caused by a single cause, but may be the result of one or more joint actions. Submersible pumps are used as mechanical equipment by us. Inadvertently, our work may be delayed due to insufficient pressure. So wha
  • How to determine the level of solar panels1. Look at the surface of tempered glassIn order to pursue production speed, small manufacturers often inadvertently drop silica gel on the surface of tempered glass, and the surface is equipped with silica gel panels to reduce power generation efficiency.2.
  • Causes and troubleshooting methods of corrosion resistant submerged pumps1. Pump filling slowReason: There is a large gap between the front lining plate and the impeller, the water outlet pipe cannot seal the air, and the exhaust is full.Solution: Adjust the gap, adjust the water outlet pipeline, an
  • Remedial methods for water leakage of submersible pumps1.The sealing ring of the submersible pump loses elasticity due to long-term use-Take out the sealing ring, cut a piece of paper or cloth with a thickness of 0.3 to 0.5 millimeters into a pad slightly larger than the original sealing ring, insta
  • Disassembly and installation methods of submersible pumpsDisassembly of submersible pump:-Use a disassembly wrench to remove the water inlet joint. -Use a disassembly cylinder to impact the conical sleeve at the lower part of the pump. -After the impeller is loose, remove the impeller, conical sleev
  • Reasons for severe shaking of stainless steel water pumps1. Loose flange and boltsThe bolt is subjected to lateral load and torque, which can easily cause the bolt to rotate and loosen. When the bolt is loose, failure to tighten it in a timely manner can lead to strong shaking of the water pump.2. M
  • Reasons for damage to water pump bearings1. Improper installation of bearings1) The use of brute force during installation, such as directly striking the bearing with a hammer, can cause significant damage to the bearing and is the main cause of deformation2) Inadequate installation, installation de
  • How to solve the problem of mechanical seal leakage?Reason一、 Failure to first fill the pump with water during trial operation;Start the pump to run without first supplying water to the mechanical seal from the external water supply;Water shortage during operation-Inspection method: Disassemble the p
  • How to prevent corrosion of submersible pumps?Controlling the corrosion of underground water on submersible pumps mainly involves two aspects:First, improve the corrosion resistance of pipes and use materials with good corrosion resistance.Second, remove or suppress some factors that cause corrosion
  • What are the hazards of submersible pump water hammer?Conditions for water hammer generation:1. Sudden opening or closing of the valve2. Sudden shutdown or startup of submersible pump unit3. Single pipe delivers water to high places (water supply terrain elevation difference exceeds 20m)4. Large tot
