Repair pump reverse osmosis, pressure boosting pump repair

Some problems booster pumps RO

1. Extraneous sounds and increased noise during operation of the pump

eleven. Development of bearing life

Replace the bearings in the head and body pump.

12. Uneven wear of brush - collector unit

Replace the pump motor.

13. Strong development of the eccentric head pump

Replace booster pump head.

2. Notable motor heating during operation

2.1. Pump capacity increase pressure chosen wrong
 
Too strong pump will always operate in overload mode, and consequently overheat.

2.2. Worn brushes

Replace brushes.

2.3. Depreciation, pollution and burning of collector

Need cleaning or replacement of the engine manifold.

2.4. Winding short circuit in the windings of the armature

It requires replacement of the engine.

2.5. Falling output and reducing motor revolutions

Any of the above reasons may affect the power and revving the engine. It is also possible to "drawdown" power supply under load.

3. degraded performance pump

3.1. It is necessary to eliminate the causes of non-pump (replace prefilters cartridges, make sure of serviceability of the membrane element, check valve, avtopereklyuchatelya, flow restrictor, exclude the possibility of a break and bend in the tubes).

3.2. It is necessary to check the serviceability of the power supply under load.

3.3. It should replace the lost elasticity of the diaphragm (the diaphragm - seal). After a few years of use in water iris "dubeet" and recirculated water between the chambers of the valve block. Chance of a gust of the diaphragm; if water gets into the bearings, and sometimes - in the engine.

3.4. Make certain elasticity, adhesion and integrity of the petals in the valve block valves. Spring Cone overflow valves must be elastic.

3.5. Eccentric drive unit head should sit on the motor shaft firmly, otherwise it does not convert the rotational force of the engine in the back - reciprocating motion of the pistons in the chambers of the valve block.

3.6. The manifold of the engine must be clean, without burning slats, brush - serviceable.

3.7. If bearings or wedged into the engine fell into the water (or the pump is in a very humid environment) are possible interturn circuit armature windings and power reduction.

4. The pump runs continuously

4.1. It is necessary to eliminate the causes of non-pump (replace prefilters cartridges, make sure of serviceability of the membrane element, check valve, avtopereklyuchatelya, flow restrictor, exclude the possibility of a break and bend in the tubes).

4.2. It can be reduced and the performance of the pump capacity (see para. 3)

4.3. You should check the high pressure sensor. Pressure should be set off within 2 to 3 atmospheres.

5. The pump will not turn on

5.1. It is necessary to eliminate the causes of non-pump (replace prefilters cartridges, make sure of serviceability of the membrane element, check valve, avtopereklyuchatelya, flow restrictor, exclude the possibility of a break and bend in the tubes).

5.2. You should check the power supply circuit - power supply, cables, terminals.

5.3. It is necessary to check the sensors. Alternately, remove them from the chains interconnected reaching two wires to the sensor.

5.4. Low pressure sensor (dry run) can not miss the pressure to complete the circuit of the engine power. You can rearrange it at the input of the system.
