Self-sealing oil suction filter outside the box

Product introduction

The self-sealing oil suction filter outside the box is installed at the oil suction port of the oil pump to protect the oil pump and other hydraulic components to avoid inhalation of polluted impurities, well control the pollution of the hydraulic system, and adjust the cleanliness of the hydraulic system.

Performance

1. Filtration precision

Filtration accuracy refers to the ability of the filter to remove particulate pollutants of different sizes. It is usually evaluated by indicators such as filtration accuracy, filtration ratio and filtration efficiency. The filtration accuracy is divided into coarse (d≥0.1mm), ordinary (d≥0.01mm) , fine (d≥0.005mm), and special fine (d≥0.001mm) four grades.

2. Voltage drop characteristics

The filter in the hydraulic system is a kind of liquid resistance to the oil, so the pressure drop will inevitably occur when the oil passes through. Generally speaking, when the filter element size and oil flow are fixed, the higher the filtration accuracy of the filter element, the greater the pressure drop. When the flow rate is fixed, the larger the filter area of the filter element, or the higher the viscosity of the oil. smaller, the smaller the pressure drop.

The allowable pressure drop of the filter element should be based on the principle that the filter element will not be structurally damaged.

3. Scale capacity

The problem of contaminant retention by a filter before the pressure drop is greater than its specified limit is called the dirt holding capacity, expressed in weight (g). The larger the dirt holding capacity of the filter, the longer its life, so it is an important indicator to reflect the life of the filter. The larger the filter area of the filter, the larger the scale holding capacity.

Scope of application

1. Metallurgy: used for the filtration of the hydraulic system of rolling mills and continuous casting machines and the filtration of various lubrication equipment.

2. Petrochemical: separation and recovery of products and intermediate products in the process of oil refining and chemical production, and particle removal and filtration of oilfield well injection water.

3. Textile: Purification and uniform filtration of polyester melt in the process of drawing, protection and filtration of air compressors, and degreasing and dehydration of compressed gas.
