Classification of diaphragm accumulators:
Diaphragm accumulators can be roughly divided into two types: welding type and screw type. Their basic structure and working principle are the same. The difference is that the welded structure uses welding to make the accumulator as a whole, while the threaded type uses the middle nut to connect the upper and lower shells of the accumulator into one.
Due to the welding method, the welded diaphragm accumulator has the smallest volume among all accumulators.
In some corrosive environments or when the medium used in the system is corrosive, the accumulator must be treated with anticorrosion. Generally, the shell is chemically coated or metal plated or the shell material is made of stainless steel.
Installation of diaphragm accumulators:
Diaphragm accumulators can be installed anywhere in the system, either horizontally or vertically. Diaphragm accumulators are designed to be fixed directly to the system with liquid-side threads, but in some poor environments (such as vibration, walking equipment), clamps are recommended.
