  • How to prevent scaling of vacuum pumpsWhat is vacuum pump scalingIt is usually formed by chemical reactions of impurities, water, grease, and other substances in the medium inside the pump under high temperature and pressure. These deposits will adhere to the internal surface of the pump, causing pr
  • Difference between self priming centrifugal pumps and ordinary centrifugal pumps1. Different startup methodsCentrifugal pump: Both the inlet pipe and the pump body need to be filled with water during startup.Self priming centrifugal pump: Inject a certain amount of starting circulating water into th
  • 6SP STAINLESS STEEL SUBMERSIBLE DEEP WELL PUMP
    Characters and AdvantagesStainless steel impellers,diffusers,outlet,connection.
    Water lubricated rubber bearing with sand channel
    High effeciency with built-in check valve to prevent back flow
    Unique laser welding creats maximum strenth,durability wear and
  • What are the reasons for insufficient flow of screw pump1. Due to the small amount of water entering the pump, it cannot keep up with the amount of water exiting the pump.Solution: increase the flow at the inlet of screw pump.2. The inlet pipe seal of screw pump is not properly handled, for example,
  • Shock absorption measures for axial flow pump units1. Adjust the operating conditions of vertical axial flow pumps by changing the angle, adjusting the speed, or bypass valve to reduce the necessary NPSH of the axial flow pump, bypass the cavitation operating point.2. Take effective drainage, waterp
  • Method to solve blockage of sewage pumpThe relevant methods for clearing blockages are as follows:1. Rinsing with clean water and solvent can effectively ablate the medium, allowing it to loosen and discharge normally;After confirming that the medium is harmless, cut off the power supply, manually d
  • 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
  • Can the deep well pump submersible pump operate at low voltage?
    Our deep well pump is a full voltage design, low voltage 90V start, 160V can run.
    o sum up, we cannot make the submersible pump operate at low voltage for a long time.
  • Reason for tripping of submersible pumpAfter installing and using the submersible pump, it will automatically trip after a period of time and immediately start without any response. After waiting for a few minutes , it can start again. What is the reason for the trip?1. Motor overload-The operating
  • 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
