Dc brushed micro diaphragm water pump K cup capsule coffee maker hydraulic piston pump motor driven piston type pump

The DHB-ZK68 dc pump is a specific type of piston pump that is commonly used in coffee machines and sprayers. It operates by utilizing a reciprocating piston to transfer fluids, such as water or other liquids.

This pump is designed to work with a DC12V voltage, making it compatible with a variety of power sources. It has a current rating below 900mA, ensuring efficient and reliable operation without excessive power consumption.

The flow rate of the DHB-ZK68 pump ranges from 100 to 300ml per minute. This allows for a steady and controlled transfer of fluids, ensuring precise measurements and consistent performance.

Additionally, this pump is capable of generating a pressure of up to 12bar. This high pressure capability makes it suitable for applications that require a strong and consistent flow, such as coffee machines and sprayers..

Technical Specification

The key component of the mini piston pump is the piston, which is usually made of wear-resistant metal or plastic. The seal between the piston and the cylinder usually uses an O-ring or lip seal. In addition, dc piston pump is also equipped with appropriate check valves or selector valves to ensure one-way flow of fluid media within the pump.

The advantages of micro piston pumps include convenient flow adjustment, stable pressure, strong self-priming ability, simple and compact structure, small size, and light weight. Due to its simple structure, small size, light weight, etc.

Features, miniature piston pumps are particularly suitable for mobile or portable applications.

How does the diaagm of a micro diaagm piston pump prevent piston wear?

The diaagm of the micro piston pump mainly prevents piston wear in the following ways:

1. Isolation function: The diaagm plays a role in isolating the piston and the liquid, avoiding direct between the piston and the liquid, thereby reducing the wear of the piston due to impurities or hard particles in the liquid.

2. Protect the piston: During the operation of the pump, the diaagm can absorb pressure fluctuations in the liquid, play a buffering role, reduce the impact force on the piston, thereby extending the service life of the piston.

3. Sealing performance: The diaagm design of some micro piston pumps has a certain degree of elasticity and can closely fit the piston, improving the sealing performance and further reducing the friction between the piston and the liquid.

4. Easy maintenance: When the diaagm is worn to a certain extent and needs to be replaced, only the diaagm needs to be replaced instead of the entire piston, which not only saves costs but also simplifies maintenance work.

How does the diaagm of a piston mini water pump improve the sealing performance of the piston?

The diaagm in the piston micro water pump improves the sealing performance of the piston in the following ways:

1. Close fit: The diaagm usually has a certain degree of elasticity and can fit closely with the piston when the piston moves, thereby effectively preventing liquid from leaking from the gap between the piston and the diaagm.

2. Adapt to pressure changes: As the liquid pressure changes, the diaagm can deform to adapt to pressure fluctuations, further enhancing the sealing effect.

3. Reduce friction: Due to the isolation effect of the diaagm, the friction between the piston and the diaagm during movement is much less than the direct friction with the liquid, thereby reducing the decrease in sealing performance due to friction.

4. Surface treatment: In order to improve the wear resistance and sealing of the diaagm, special surface treatment technology, such as coating or plating, can be used to enhance the hardness and corrosion resistance of the diaagm.

5. Structural design: The design of the diaagm should consider factors such as its shape, material, and thickness to achieve better elasticity, pressure resistance, and wear resistance, thereby improving the sealing performance of the piston.

6. Optimize installation: Correct installation and adjustment of the diaagm ensures that it always maintains the correct position and shape during pump operation, which also helps to improve the sealing performance of the piston.

How do diaagms in micro piston pumps adapt to pressure changes?

The diaagm in a piston dc diaagm water pump is usually made of elastic material and has a certain degree of plasticity and resilience. When the pressure inside the pump changes, the diaagm can deform to adapt to the change in pressure.

Specifically, when the pressure inside the pump increases, the diaagm flexes or expands in the direction of decreasing pressure to balance the pressure difference. At the same time, the elastic material of the diaagm can absorb and disperse part of the pressure

force, reducing the impact force on the piston, thereby maintaining the sealing performance between the piston and the diaagm.

In order to better adapt to pressure changes, the diaagm design of micro piston pumps usually takes into account factors such as its thickness, material and structure.

For example, the use of highly elastic materials and reasonable thickness design can improve the pressure resistance of the diaagm: optimizing the structure of the diaagm so that it can better adapt to pressure changes can also improve its density.

sealing performance.

In addition, micro piston pumps are usually equipped with pressure regulating devices, such as pressure valves or pressure sensors, to automatically adjust the pressure within the pump. When the pressure in the pump is too high or too low, these devices will

By adjusting the working status of the pump or the fluid flow, the pressure inside the pump is maintained within an appropriate range, thereby protecting components such as the diaagm and piston from excessive pressure.
