How to prevent water leakage of small submersible electric pump?

Classification:


1. how to prevent small submersible pump mechanical seal leakage: Mechanical seals, also known as end seals, have a pair of ends perpendicular to the axis of rotation. Under the action of fluid pressure, the external elastic force of the machine is compensated, and the end face is kept matched with the other end by the auxiliary seal and slides relatively to prevent fluid leakage.

 Small submersible pumpHow to prevent water leakage?

The main products of small submersible electric pump manufacturers are: micro water pump, DC micro water pump, electric micro vacuum water pump, vacuum pump, air pump, micro solenoid valve, water valve and other three major types of diaphragm pump products, 100 more than a series of parameters, and medical electronics, providing professional pump valve product solutions in the fields of beauty and beauty, household appliances, bathroom, detection and analysis, etc. Let's talk about how to prevent small submersible pump water leakage?

In some cases, the small submersible pump may leak after a period of time, but the user will feel that it must be replaced, but if we use the micro pump for maintenance, the micro pump will not leak. So how to prevent micro pump leakage?

How to preventSmall submersible pumpMechanical seal leakage?

Mechanical seals, also known as end seals, have a pair of ends perpendicular to the axis of rotation. Under the action of fluid pressure, the external elastic force of the machine is compensated, and the end face is kept matched with the other end by the auxiliary seal and slides relatively to prevent fluid leakage.

Common periodic leaks:

1. The axial turbulence of the micro pump rotor is large, the interference between the auxiliary seal and the shaft is large, and the moving ring cannot move flexibly on the shaft. When the micro water pump is turned over, the dynamic and static rings are worn, and the compensation displacement cannot be obtained.

Countermeasures: When assembling mechanical seals, the axial displacement of the shaft should be less than 0.1mm, and the interference between the auxiliary seal and the shaft should be moderate. While ensuring radial sealing, the movable ring can move flexibly on the shaft after assembly.

2. Insufficient amount of cover lubricating oil causes dry friction or scratches on the sealing end face.

Countermeasures: micro pump oil chamber lubricating oil level should be higher than the dynamic, static ring sealing surface.

How to chooseSmall submersible pump?

1. micro water pump normal temperature working medium

(0 ≤ 50 ℃), simply pumping or solution, not using water and gas, but requiring self-priming force, flow rate and output pressure.

Note: The pumped working medium is water, oil-free, non-corrosive liquid and other solutions (cannot contain solid particles, etc.).

1. The flow rate is large (about 4 × 20 liters/minute), and the pressure requirement is not high (about 1 × 3kg). Mainly used for circulating water, sampling, lifting, etc., requiring low noise, long life, high self-absorption. BSP, CSP and other products are available.

2. The flow rate is not high (about 1~5 liters/min), but the pressure is high (about 2~11kg). Mainly used for spraying, pressurizing, car washing, etc. There is no need to work under high pressure or heavy load for a long time, and ASP, HSP and other series can be selected.

3. For the pumping and spraying of the coffee table, the volume is as small as possible, the flow is small, and the noise is low (about 0.1~3 liters/minute). Optional ASP and other series products are also required.

2. normal temperature working medium

(0-50 degrees Celsius), need to pump or pump (can be mixed with water or idling, idling), pay attention to the volume, noise, continuous use and other performance.

Description: Both water and gas are required, and the pump can be idling for a long time without damaging; it can run continuously for 24 hours; especially the small size and low noise, but the flow and pressure requirements are not high.

1. Use a micro pump to pump air or vacuum, but sometimes liquid water will enter the pump cavity.

2, the micro pump must be able to pump and pump.
