　　Small submersible pumpWhat are the characteristics and advantages?

Many users in the use of small submersible pump, because the pump flow is too large, the need to adjust the flow. In the past, it was adjusted by reducing the voltage or adding valves, which brought a lot of inconvenience.

The main products of small submersible pump manufacturers are: micro pump, DC micro pump, electric micro vacuum pump, vacuum pump, air pump, micro solenoid valve, water valve and other three categories of diaphragm pump products, 100 more than a series of parameters, in cooperation with medical electronics, in beauty, household appliances, sanitary ware, testing and analysis to provide customers with professional pump valve product solutions.

The main advantages of small submersible pump are as follows:

1, the use of brushless motor, long life, small interference.

2, overheating and overload protection: as expected may cause abnormal temperature rise of the pump motor. When micro, the pump will automatically protect the system shutdown to prevent the motor from burning; if foreign matter falls into the motor, it may be stuck, and the pump will automatically control the protection shutdown to prevent the motor from burning.

3, can be pumped directly, can also be pumped. It is a water and gas pump; it can be self-priming or "dry running".

4. For the sake of simplicity and convenience, the wiring on the pump motor is directly inserted into the speed control box, and the flow rate of the micro pump can be changed by rotating the selection button on the speed control box. Motor speed.

5. The micro-pump motor has a speed feedback signal. Therefore, the running state of the pump can be known, which is convenient for closed-loop control and makes the system more intelligent.

How to maintain the cold winter seasonSmall submersible pump?

As the temperature drops in winter, the water pump stops many times due to the temperature. At this point, the pump inspection and maintenance is particularly important. The following is how to repair and maintain the micropump in winter.

1. When the micro electronic water pump is stopped, the remaining water in the pump and the pipeline should be drained, and the soil outside the enterprise should be cleaned to prevent the pump body and the water pipe from exploding after freezing.

2. The cast iron parts such as water pump and elbow of bottom valve should be cleaned with steel wire brush and anti-rust brush, and then painted with anti-rust paint. After drying, it should be stored in a ventilated and dry place in the machine room or storage room.

3. Belt drive, wash and dry with warm water after removal, hang in a dry place, avoid direct sunlight. In addition, it should not be stored in a place with oil, corrosive substances and smoke. The development of the micro pump reminds that under any circumstances, the belt can not be stained with oil, diesel or gasoline, nor can it be stained with viscous substances such as rosin.

4. Check the ball bearing for wear, such as lining, agitator, ball wear or surface spots to be replaced. The bearings are cleaned, buttered and reloaded with gasoline or kerosene without replacement.

5. For the development of micro water pumps, check whether there are cracks or holes in the impeller design of the working water pump, and whether there is looseness between the fixed nuts of the impeller. If there is any damage, it should be repaired or replaced. If the impeller is excessively worn or damaged, replace it with a new one. Local damage can be welded or repaired with epoxy mortar. After the repair of the impeller design should generally be carried out system static balance test. Check the clearance of impeller damping ring, repair or replace if the clearance exceeds the specified value.

6. The severity of the pump shaft bending or wear should be repaired or replaced, otherwise the rotor structure is unbalanced and the related working parts are worn.
