Membranes for hydroaccumulators is the types, purpose and description of the process of replacing them

Membrane are components of accumulators for pumping stations. In this case, it's an important fixture. They are designed for the separation capacity of the accumulator into two chambers: the air and water. This is the main feature of this device. Professionals often confuse these cameras. It must be remembered that the injection water is in the membrane, and the air between it and the wall of the accumulator is compressed, creating the right pressure.

Types of products

To use, membranes for hydraulic accumulators, heating and water. Consider each type in more detail.

• Membrane accumulator water is white. They are made of natural rubber. This material is able to withstand the action of bacteria and meets the standards of hygiene and sanitation.
  - Temperature range: 0 to 70 °C.
  - maximum pressure - 7 bar.
  
  
• Membrane accumulators for heating can be black. They are made of special rubber EPDM. This material is resistant to changes in pressure and significant temperature in heating systems.
  - Temperature range: -10 to 99 °C.
  - maximum pressure - 8 bar.

Changing the diaphragm in the accumulator. Process description

Membrane accumulator almost always becomes unsuitable solely because of the fault of the user. Theoretically, for a specified product, which, for example, made of rubber EPDM, the warranty of about ten years of service. There are accumulators with membrane that is not removed. It is regarded as a certain guarantee from the manufacturer, then there will be a whole different operating conditions. In the home use units, are equipped with a pear-shaped these devices, a membrane for pressure tank (100 l) resembles the shape of a stocking with input and output.

Replacement membrane for pressure tank household pump 

This process is not so difficult. Initially, you need  to disconnect the power and reset system pressure.

• Despite the unsuitability of membranes for hydroaccumulators, need more time to verify the absence in the device of air pressure.
• Then, Unscrew the bolts, remove the flange and get damaged membrane.
• Screwing the flange in its place, make pumping air up to 1.4 atmospheres.
• Then fill the water pump, connect the power and pump up the system pressure.

You can then safely use the device.

Tip

This product available for sale is common, as it is a consumable item. You can still inquire about his availability from the manufacturer or supplier of accumulators. They will assist you when selecting the specified device. You need to consider that membrane one manufacturer quite often does not approach the device from another because of differences in the diameter of the neck. Also do not forget about periodic checks of air pressure in the fixture to soon not have to re-do the replacement of the membrane in the accumulator.
