The characteristics of three kinds of water heater pump

The characteristics of three kinds of water heater pump

1.Brush dc water heater pump

  When the brush dc water heater pump is working,the abrasion of carbon brush is unavoidable once motor rotation.When wearing clearance of carbon brush is large,the noise of pump will be higher too.

  Advantage:low price

2.Brushless dc water heater pump(motor type)

  Brushless dc water heater pump(motor type) is made of brushless dc motor and impeller.Because of the gap between stator and rotor,the water will penetrate into the motor if the pump is working for a long time(the motor may be burn out).

  Advantage:The brushledd dc motor has been standardized.Many manufacturers can produce this motors in large quantities,so the price of motor is low.

3.Brushless dc magnetic isolated water heater pump.

  The brushless dc pumps is made of environmentally friendly materials,so the noise of pump is very low,the volume is small,and the performance is stable.Besides,the parameter of brushless dc pump can be adjusted through the stator winding,and the pump can run in wide voltage.

  Advantage:Long life and low noise,the pump can be used for hot-water circulation.The water heater pump can be installed underwater and it is waterproof completely.The ceramic shaft of pump is high-precision and with good vibration resistance.

Announcements for operating aquatic breeding pump

When operating aquatic breeding pum,we should pay attention to these following announcements:

1.In order to guarantee the performance of the products,the aquatic breeding pump is not allowed to run without water.

2.The mini pump shall be immersed in water when it is working.

3.The ferromagnetic impurities and particles are not allowed to enter in magnetic driver.

4.After converying crystallization or precipitation medium,the micro pump should be washed timely.

5.The aquatic breeding pump should run in the prescribed temperature condition.If the temperature of medium exceed standard,it will cause some problems,such as magnet demagnetization or the performance of control circuit degradation。

6.Please discharge the air in the pump cleanly before connecting up the hose to the outlet of mini pump.

7.Don’t connect the circuit polarity in the wrong way.

8.Before using it,please confirm that the dc power supply is not exceeded the highest rated voltage of mini dc pump.Otherwise,the pump would be burn.

The advantage of aquarium wave pump

In general,the aquarium wave pump which can make artificial flow and waves is widely used in fish breeding.The artificial flow and waves can bring the fish such feeling that they are living in the real river,they will wring their bodies in the flow,this is conducive to the growth of fish.

The advantage of aquarium wave pump:

1.maintenance-free,DC,low voltage and no leakage,safety and environmental protection;

2.Super smooth, long life, can work for 20000 hours continuously;

3.Small size and large flow;

4.Super mute,do not produce electromagnetic interference;

5.Low cost,Easy to install.

6 tips for using mini submersible pump in safety

The most obvious feature of mini submersible pump is small and light.In order to ensure the submersible pumps’s normal working life,Stable performance and avoid accident,we should pay attention to these following tips when using micro submersible pumps:

Tip 1: avoid frequent switch

Don’t open and close the pump frequently.It will cause backflow when pumps stalling,if we restart it immediately,the winding would burn out because of too large starting current.Due to the startup current,the motor windings of submersible pump will burn out too because of frequent starting.

Tip 2:install leakage protector

The main function of leakage protector is to prevent us from electric leakage.As we know,the micro submersible pumps are working underwater, electric leakage will cause energy loss and even cause an accident of electric shock.But if pumps are equipped with leakage protector,the  leakage protector will cut off the power supply of mini submersible pump as long as the leakage value of pump exceed the action current value of leakage protector.

Tip 3:choosing power supply which can comply with standard

If the power supply and the pump are far part,the cross-sectional area of connection cable shoulb be bigger and the joint should be less,to ensure that the normal voltage is between 342-418v.In order to ensure safety,you can embedded a iron line(longer than 1m) in wet ground where is near power supply or pump.

Tip 4:don’t make the submersible pump overload working for too long time

In order to avoid making the submersible pump overload working for too long time,please don’t pump water which contains too much sand,and observe whether the current value is normal.If the current value is too large,please stop it and check the pump.Besides,the electric pump can’t run without water for too long time.

Tip 5:check it frequently and repair it timely if it was broken.

Checking the motore frequently should be your daily work.Once finding that the lower cover has crack,the rubber seal ring was broken or invalid,you should replace and repair it timely.

Tip 6:the direction of rotation of motor must be right

Before opening the pump,you should make certain the direction of rotation of motor.At present,many types of submersible pump are available to pump out water in both corotation and inversion,but if the motor is in the condition of inversion,the water yield will be small and the current will be large.Besides,if the motor is in inversion for a long time, the motor winding would be damaged.
