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

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

How can the flow rate of submersible pumps decrease?Reasons for flow decrease:1. The impeller or pump body fluid flow path is blocked by debrisTreatment method: Disassemble the submersible pump, remove debris from the impeller or pump body flow path, make the impeller rotate smoothly and quickly, an

Characteristics of high-temperature resistant submersible pump1. The high-temperature resistant submersible pump has an ultra-long service life, no maintenance required, small size, high efficiency, and low power consumption.2.The stator and circuit board of the motor are sealed with epoxy resin and
