Like all devices, particle counters will also malfunction within a certain period of time. Let the particle counter manufacturer bring you an analysis of the hydraulic component factors:

1. Sealing factor

The reliability of hydraulic systems largely depends on the sealing of the hydraulic system. Due to the unreasonable selection of sealing structures and non-standard selection of sealing components in the design, the compatibility type of hydraulic oil and sealing materials, load conditions, limited pressure, working speed, and changes in ambient temperature were not considered in the design. These all directly or indirectly cause seal damage and hydraulic oil leakage to varying degrees.

2. Manufacturing factors of hydraulic components

All hydraulic components and sealing parts have strict requirements for dimensional tolerances, surface treatment, surface smoothness, and form and position tolerances. If the manufacturing process exceeds the tolerance, such as the piston radius of the oil cylinder, the depth or width of the sealing groove, the hole size for installing the sealing ring exceeding the tolerance, or causing out of roundness due to processing problems, burrs or dents, chrome plating detachment, etc., the sealing component will deform, scratch, crush or not press firmly, causing it to lose its sealing function. Will cause inherent leakage points in the parts themselves, resulting in leakage after assembly or during use.

3. Assembly factors

Rough operation should be avoided during the assembly of hydraulic components. Excessive force may cause deformation of the parts, especially when using copper rods to strike the cylinder body, sealing flanges, etc; Before assembly, the parts should be carefully inspected. During assembly, the parts should be dipped in a small amount of hydraulic oil and gently pressed in. Diesel fuel should be used for cleaning, especially rubber components such as sealing rings, dust rings, O-rings, etc. If gasoline is used, they are prone to aging and lose their original elasticity, resulting in leakage due to the loss of sealing function.

4. Hydraulic oil contamination

Hydraulic oil contamination refers to the harmful effects of impurities such as moisture, air, small solid particles, and gel like products in hydraulic oil on the hydraulic system. Especially small solid particles can accelerate part wear, causing components to malfunction; At the same time, it can also scratch the seals, increasing leakage. The mixing of moisture and air reduces the lubrication ability of hydraulic oil, causing it to oxidize and deteriorate; Generating cavitation, accelerating the damage of components; Causing vibration and crawling in the hydraulic system. Solid particles and gel like substances block the filter, making it difficult for the hydraulic pump to operate and generating noise; Blocking small holes or gaps in valve components can cause valve malfunction.
