DC micro self-priming water pump for coffee machine

What is the efficiency of Micro Water Pump?

Of course, the actual efficiency will be affected by many factors, including pump design, manufacturing process, use environment, liquid properties, etc. Therefore, when selecting and using a micro diaphragm water pump, comprehensive considerations need to be made based on specific application scenarios and needs.

In addition, micro diaphragm water pumps also have other advantages, such as small size, light weight, low noise, long life, etc., which make them widely used in many fields, such as household water supply, agricultural irrigation, industrial liquid transportation, etc.

Technical Specification

When purchasing a mini pump for use in a coffee machine, there are several factors to consider:

1. Flow and pressure: The flow and pressure of the Self Priming Micro Water Pump are the key parameters for selection. The extraction of the coffee machine requires a certain pressure and flow to ensure full extraction of the coffee powder. Generally speaking, the water pump pressure of an espresso machine is between 15-20bar, and the golden extraction pressure is 15bar. Therefore, the DC Water Pump chosen needs to be able to provide enough pressure to meet the needs of the coffee machine.

2. Durability: The coffee machine needs to be used frequently, so the micro diaphragm water pump needs to have high durability. Choosing products from well-known brands and reliable quality can reduce the frequency of breakdowns and repairs.

3. Noise: The micro diaphragm water pump may produce noise during operation, which may affect the user's experience. Therefore, choosing products with less noise can better meet user needs.

4. Price: Finally, price is also a factor to consider. The price of micro diaphragm water pumps varies depending on factors such as brand, quality, functions, etc. You need to choose according to your own budget and needs.

How is the efficiency of a DC Diaphragm Water Pump limited by what factors?

First, the structure and material of the pump have a great impact on its efficiency. For example, some fluids that are volatile, crystallized, or contain particles may reduce the volumetric efficiency of a diaphragm pump. In addition, the working status of the pump, such as changes in working conditions such as inlet pressure and outlet resistance, will also have an impact on the volumetric efficiency.

Secondly, the nature of the medium will also affect the efficiency of the DC Liquid Pump. For example, physical properties such as the viscosity, density, and temperature of the medium will affect the volumetric efficiency of the pump. For media with high viscosity and high consistency, the volumetric efficiency is generally low.

In addition, the driving method will also affect the liquid flow rate, thereby indirectly affecting the efficiency. For example, the air pressure and driving frequency will affect the discharge flow rate of the diaphragm pump.

In addition, the efficiency of mini liquid may also be affected by the structural parameters of the pump. For example, the larger the inner diameter and length of the pump, the greater the resistance of liquid passing through the pump and the smaller the liquid flow rate, thus affecting efficiency. The larger the diameter of the piston and diaphragm of the pump, the higher the working efficiency of the pump, the greater the liquid flow rate, and the efficiency increases accordingly.

Finally, the very working principle of a Mini Diaphragm Pump can also lead to efficiency limitations. For example, since a diaphragm pump delivers liquid by changing the volume between diaphragms, when the operating pressure changes, the change in volume will cause fluctuations in flow, thereby affecting efficiency. In addition, the diaphragm of the diaphragm pump is a wearing part and needs to be replaced regularly. Damage or aging of the diaphragm will also affect the normal operation of the pump, thereby reducing efficiency.

How to solve the problem of Mini DC Diaphragm Pump not working?

There may be many reasons why the Membrane Water Pump does not work. Here are some common faults and their solutions:

1. The power supply voltage is too low: Check the power supply voltage to ensure that it meets the rated voltage range of the pump. If the voltage is too low, you may need to replace the power supply or adjust the voltage.

2. Water enters the pump body: If water enters the pump body, it should be stopped immediately and repaired. The pump body or seals may need to be replaced.

3. Diaphragm rupture: The core component of the micro diaphragm water pump is the diaphragm. If the diaphragm is ruptured or aged, it will also cause the pump to not rotate. At this time, the diaphragm needs to be replaced in time.

4. Air valve failure: If the air valve is aged or blocked, it will cause the air valve to fail to work, which will cause the pump to not work. At this time, the status of the air valve should be checked and the air valve should be replaced in time.

5. Poor sealing: If the sealing is not good, there will be leakage or insufficient flow, which will cause the pump to not work. At this time, you should check whether the seals are intact and replace damaged seals in time.

6. Motor failure: If the motor fails or is damaged, the pump will not work. At this time, the motor status should be checked and the motor should be replaced in time.

7. Operational errors: During the operation of the diaphragm pump, if the correct operating procedures are not followed, the pump will not work. At this time, the correct operating procedures should be followed.

What should I do if there is no pressure in the Mini DC Pump ?

If the micro diaphragm water pump has no pressure, you can take the following measures:

1. Check whether the inlet valve is fully open or blocked. If so, deal with it in time to ensure that the inlet flow of the pump is sufficient.

2. Check whether the air valve is normal. If there is a problem, the air valve should be cleaned or replaced.

3. Check whether the diaphragm is aged, damaged or leaking, and replace the diaphragm in time.

4. Check whether the air source of the drive system is stable and whether the working pressure is normal. If it is abnormal, adjust or replace the air source equipment.

In addition, you need to pay attention to the following points:

1. Make sure the pump is installed in the correct position and avoid the inlet pipe being too long or bent to reduce inlet resistance.

2. Check whether the pump is in correct operating condition, such as whether the motor rotation is correct, whether the pump is at normal operating temperature, etc.

3. If the pump has not been used for a long time, the diaphragm may be adhered or blocked, and the diaphragm needs to be cleaned or replaced.
