High-pressure blowers may experience sliding system failures.

The noise generated by high-pressure blowers is proportional to the sixth power of blade speed.  Blade pulsations within the airflow passing through the blower may induce noise.  Two distinct noise sources exist at different frequencies: one originates from the pressure field, and the other is dynamic noise from blade pulsations induced by airflow. Sliding system failures in high-pressure stainless steel blowers stem from: insufficient clearance between the oil pump bearing bore and gear shaft, inadequate radial clearance between the housing bore and gear, insufficient clearance between the gear and bearing, insufficient end clearance at the side cover, poor quality of sliding oil in stainless steel blowers, unsuitable viscosity, and high moisture content.  Then inspect the electronic control section.

Experience: If the high-pressure blower fails to start, first check whether the rotating components of the on-site equipment are jammed.  Inspect the motor for issues.  Ensure the stainless steel blower is within its applicable operating range during use.

Motor: Check if the windings are burnt out.  The operational status of the high-pressure blower motor and bearing condition can be tested separately.  Blockage in the rotating parts of the stainless steel blower.  Motor overload preventing rotation.

To ensure normal operation, inspect the lubricating oil of the high-pressure blower and verify if the water-cooled bearing seat is seized; check for misalignment of bearings and bearing equipment; assess bearing damage or end-of-life conditions; and examine for imbalance between the equipment shaft and motor shaft.

For detailed information on inspecting high-pressure FRP blower motor faults, contact our staff through various channels to obtain answers on how to diagnose FRP blower motor issues! How to inspect high-pressure FRP blower motor faults:

Visual Inspection Method  Observe whether the terminal box and winding ends show signs of scorching. Heated windings may exhibit dark brown discoloration and emit an unusual odor.  Temperature Detection Method  After running the FRP fan under no-load conditions for 20 minutes, touch various parts of the windings to determine if temperatures exceed normal levels.

Live Testing Method  Measure the motor with an ammeter. Excessive current in any phase indicates a short circuit in that phase.  Bridge Check  When measuring the DC resistance of the windings, the typical difference should not exceed five percent.  If a phase shows low resistance, it indicates a short circuit fault.

Short Circuit Detection Method  When the test winding of a FRP fan shorts, the steel plate vibrates. Megohmmeter Method  Measure the edge resistance between two phase windings.  If the reading is very low or zero, it indicates a short circuit between the two phase windings.

Voltage Drop Method  After connecting three windings in series, apply low-voltage AC power to detect short circuits. Current Method  During no-load operation of FRP fans, first measure three-phase currents, then compare changes in two-phase currents.  If the high-voltage fan current remains unchanged with power supply variations, the single-phase winding with higher current is shorted.
