Hengst filter PWR3-A00 series commonly used models

The turbulent structure inside the Hengst filter PWR3 is not only closely related to its separation performance, but also directly affects the energy loss of the unit operation. Based on the application analysis of centrifugal filters in actual micro irrigation projects, Zheng Tiegang et al. [41] pointed out the application conditions of centrifugal filters and the theoretical basis for selecting different types of centrifugal filters according to different irrigation water sources. Ren Liancheng et al. [42] utilized the existing theoretical research results of centrifugal filter flow field analysis to propose the short-circuit flow problem existing in conventional centrifugal filters. Based on this problem, they added a structural optimization idea of axial zero velocity envelope surface filter screen, and evaluated its rationality and feasibility

The commonly used Hengst filter PWR3-A00 series is an efficient and reliable filter, consisting of a filter element, a filter housing, a sealing ring, and other parts. Among them, the filter element is the core component of the filter, and different filter materials and structures can be selected according to different filtration requirements. The filter housing is a component that protects and fixes the filter element, usually made of metal material. The sealing ring is a component that connects the filter element and the filter housing, used to ensure the sealing between the filter element and the filter housing, and is widely used in various mechanical equipment and vehicles.Hengst filter PWR3-A00 series commonly used modelsThe turbulent structure inside is not only closely related to its separation performance, but also directly affects the energy loss of the unit operation.

At the same time, they discussed the influence of the filter screen on the flow field and related issues.

1、 Working principle

The working principle of Hengst filter is to filter out impurities, pollutants and other substances in the oil or air entering the equipment through the filter element, ensuring the normal operation of the equipment. When oil or air flows through the filter element, the filter element will block impurities, pollutants, and other substances from passing through it, thus achieving the filtering effect. When the pollutants in the filter element reach a certain level, it is necessary to replace the filter element.

2、 Application

Hengst filters are widely used in various mechanical equipment and vehicles, including automobiles, construction machinery, ships, generator sets, etc. In automobiles, it is mainly used for filtering in engine, air conditioning system, fuel system and other parts. In construction machinery, it is mainly used for filtering hydraulic systems, air filters, and other parts. In ships and generator sets, it is mainly used for filtering fuel systems, lubrication systems, and other parts.

3、 Maintenance

The maintenance of Hengst filters mainly includes replacing the filter element and cleaning the filter housing. The replacement cycle of the filter element is generally determined by the usage and environmental conditions of the equipment. It is generally recommended to replace the filter element every certain time or after a certain number of hours of equipment operation. When cleaning the filter housing, it is necessary to remove the filter element, clean the inside of the filter housing with clean oil or water, and check whether the filter housing is damaged or corroded.

When replacing the filter element or cleaning the filter housing, the following aspects should be noted:

1. Ensure that the equipment is in a stopped state to avoid the equipment still running during filter replacement or cleaning.

2. When replacing the filter element or cleaning the filter housing, it is necessary to drain the oil or air from the equipment to avoid polluting the environment.
