How ZW self-priming pump works

The **ZW self-priming pump** was developed to provide a reliable water source for everyday use, especially in southern China where it's widely adopted. Its operation relies on the principle of water velocity and momentum to drive the impeller, allowing it to lift water from a lower level to a higher one. One of its main advantages is the ability to draw water directly from rivers or other natural sources, which makes it highly practical in rural and agricultural settings. Unlike traditional pumps that require pre-filling with water before operation, the ZW self-priming pump is designed to eliminate this inconvenience. It can start pumping without needing to manually fill the pump body or inlet pipe with water first. This is made possible by its unique internal structure, which helps maintain a vacuum even when the motor is off. As a result, it doesn't lose its prime easily, making it more efficient and user-friendly. The ZW pump is not only convenient but also versatile. It’s commonly used in agriculture for irrigation of crops like wheat and corn, and it's easy to set up—just connect it to a power source and it's ready to go. In industrial applications, it plays a crucial role in chemical plants, construction sites, and printing facilities. It's also essential for firefighting operations, where quick access to water can be life-saving. What makes the ZW self-priming pump truly valuable is its adaptability. It can work with various types of filter presses and is suitable for both fresh and seawater, provided the solid content isn’t too high. This versatility ensures that it remains a vital tool in many different environments. Whether it's for farming, industry, or emergency services, the ZW self-priming pump continues to prove its worth through efficiency, reliability, and ease of use.

Rod Seals

1. Components of piston rod seal:

Polyurethane, polyformaldehyde, rubber

2. Purpose and function of piston rod seal:

The rod seal belongs to the dynamic seal. It is the seal that moves with the piston rod. It is one of the important components on the hydraulic support.

3. Use position of piston rod seal:

Guide sleeve, piston

4. Working principle of piston rod seal:

It is used at the contact part between the guide sleeve and the outer cylinder to seal the emulsion in the outer cylinder.

5. What effects will be caused by improper use or operation of piston rod seal:

1. Improper selection of cavity support material will wear the cavity and piston rod.

2. The size of the friction pair is inappropriate, causing wear.

3. Improper thread guide angle of cylinder barrel and piston end wear the sealing ring.

4. The seal ring is worn due to improper installation guide angle of the seal.

5. The surface of cavity and piston rod is rough, with scratches and worn seals.

6. The outer cylinder leaks and the jack does not maintain pressure.
