Identifying Top-Notch Accumulators by Their Surface Conditions

When identifying top-level accumulators, their surface conditions are a key evaluation factor. The following are several key points used to identify top-level accumulators through surface conditions:
Surface smoothness:
Top tier accumulators should have extremely high surface smoothness, which helps reduce resistance and wear during fluid flow.
Ra value is a commonly used indicator to measure surface smoothness, and the surface Ra value of top accumulators is usually below 0.8 μ m to ensure smooth fluid flow.
Surface flatness:
The surface flatness of the accumulator is crucial for ensuring uniform fluid distribution and preventing leakage.
The surface of top accumulators is usually processed with high precision to ensure that there are no obvious bumps or deformations on the surface, which helps improve the efficiency and safety of fluid transmission.
Anti corrosion and protective coatings:
Anti corrosion coatings are crucial for extending the service life of accumulators and preventing corrosion.
Top tier accumulators are usually coated with high-quality anti-corrosion coatings, such as epoxy or polyurethane, which have excellent corrosion resistance and durability.
The thickness and hardness of coatings are also important indicators for evaluating coating quality. The coatings of top accumulators usually have sufficient thickness and hardness to ensure their long-term effectiveness.
Surface cleanliness:
The cleanliness of the accumulator surface is crucial for maintaining fluid purity and normal system operation.
The top accumulator undergoes a strict cleaning process during production to ensure that the surface is free of impurities such as oil and dust.
The evaluation of cleanliness can be carried out through visual inspection, residue testing after chemical cleaning, and other methods.
In summary, top accumulators can be identified by evaluating their surface smoothness, flatness, anti-corrosion and protective coatings, cleanliness, connection and sealing parts, wear resistance, and compliance with industry standards and certifications.
