Fault

reason

Corrective Action

No fluid.

There's air in the inhaler tube.

Two, too high.

3. Require Head to be larger than pump Head

Four, over-barrel. Too much traffic.

5. Reverse

1 , clear of pipes, clear of air

2 , lower height of pump installation

Three, switch to Head's big pump.

4 , for Port Size and pump mouths, etc.

5. Change of direction

Insufficient Flow

1 , leaf wheel damage

2 , Seal damage

3. Undercount

Four, Inlet overload.

Five, the Outlet tube is too bent, too resistance.

1 , change new leaf wheel

2 , change of seal

3. Increased turnover

4 , as required, reload pipes

5 & nbsp;, rationalization of pipelines

Head's not enough.

1. Delivery media containing gases or media pasting

2. Damage to wheels and blades

3. Insufficient turnover

1. Reduce media viscosity or increase pressure for injection

2. Replacement of leaf wheels

3 & nbsp;, increase in transfer

Axis leakage

1. Mechanical sealed card loops

Two, axle-end card loop transition size gap is too big.

One, two internal hexagonal snails.

2. Dismantling the pump, axle, carding the F4s with thin membrane circles.

The seal's leaking.

1. Inadequate selection of sealed component materials

2. Exhaustion for severe wear

Three, the ring kisses.

4 & nbsp;, friction-exhausted fragrance

1. Description of the medium in the pump chain with appropriate motion rings

2. Change wear and tear and adjust spring pressure to reduce wear and tear

3. Repositioning of the hysteria of the seal hysteria.

Pump disassembly. Sealed rings with required vertical error & lt; 0.10

There's a noise or pump vibration inside the pump.

One, the pump axis is different from the Motor axis.

2 , Flow exceeds range of use to generate gas erosion

3. Pumps generate gas erosion

4 , electrical motor and axle wear

1 , correction pump axle centre

2. Select the appropriate pump type.

3. Reduce the temperature or increase the injection pressure of the medium

4. Cleaning or changing bearings

Selection Information Required

Please provide medium, concentration, flow, total head or pressure, temperature, viscosity or solids, voltage, frequency and installation method. DFIN Pump will confirm the suitable model and materials.
