Membranes for accumulators: variety, purpose and description of the replacement

click fraud protection

membranes is a component of hydraulic accumulators for pumping stations.In this case, it is unimportant devices.They are designed for the separation of the accumulator tank into two chambers: air and water.This is the basic property of this device.Experts often confuse these cameras.Keep in mind that water injection takes place in the membrane, and the air between it and the wall of the accumulator is compressed, creating the desired pressure.

Species

articles for use, there are membranes for accumulators heating and water supply.Consider each type of detail.

  • Membranes for water accumulators are white.They are manufactured from 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.
    - Limit pressure - 7 bar.

  • Membranes for accumulators heating may be black.They are made of special rubber - EPDM.This material is resistant to extremes of pressure and temperature in large heating systems.
    - Temperature range: -10 to 99 ° C.
    - Limit pressure - 8 bar.

Replacing the diaphragm accumulator.Description of

membrane accumulator almost always becomes unusable solely because of fault of the user.Theoretically, the specified product, which, for example, made of rubber EPDM, warranty is about ten years of service.There are hydraulic accumulators with a membrane, which can not be removed.This is regarded as a certain guarantee from the manufacturer, then there will be a whole different operating conditions.At home use units equipped with pear specify the device and the membrane to the pressure accumulator (100 l) resembles the shape of a stocking with the input and output.

Replacement membrane accumulator for domestic pump

This process is not so complicated.Initially, you must turn off the power and reset the system pressure.

  • Despite the unsuitability of membranes for accumulators, need more time to verify the absence of air pressure in the device.
  • Then unscrew the bolts, remove the collar and pulled spoiled membrane.
  • Having fastened flange into place, make the injection of air to 1.4 atmospheres.
  • then be filled with water pump, connect the power and pump pressure in the system.

After that you can safely use the device.

Council

This product is available for sale is common, because it is a consumable item.You can also ask about his availability at the manufacturer's or supplier's accumulators.They will assist you in the selection of said device.Keep in mind that a membrane manufacturer quite often do not fit to the device from another because of differences in the diameter of the neck.Also do not forget about the periodic inspection of air pressure in the device that will soon not have to again make a change in the membrane accumulator.
