As pneumatic diaphragm pumps They are very versatile equipment that can be implemented in different industrial sectors. Being able to operate from the transfer of fluids with high viscosity to agro-chemicals, these pumps have a functional and simple design, being in fact very efficient and usable. However, like any team they can also present some problems
Common problems with bomba diaphragm pneumatics
Diaphragm break
The diaphragm is one of the most important parts of the pneumatic diaphragm pump, and is also subject to damage due to the mechanical, thermal and chemical stresses to which it is subjected. Depending on the material, the diaphragm may have different resistance to the fluid being pumped, being subject to damage and wear.
Solution: First of all, it is essential to understand what may be affecting the durability of your pump's diaphragm. The first step is to use a quality diaphragm that can adequately resist the fluid being pumped and the working conditions to which it is subjected. To avoid this problem, it is necessary to adjust the working pressure and carry out a preventive maintenance process to identify wear or damage that could affect this structure. In the event of deterioration or rupture, it is essential to immediately replace the component.
Leaks
Pneumatic diaphragm pump leaks are generally related to defective gaskets. These leaks end up reducing performance, impacting the efficiency of your pump, contributing to liquid waste and even more serious problems when pumping abrasive or dangerous fluids.
Solution: both when installing and maintaining your pump, it is essential to ensure that all joints are tightened according to the equipment specifications. This way you can guarantee an airtight seal and avoid leaks that are so harmful to the industry. In the case of worn or damaged gaskets, the components must be replaced.
Bolt grip
It is natural for screws to loosen during operation, although this is more common in plastic pumps, this problem can affect pumps of all types mainly due to the vibration that occurs during operation. Loosening screws can encourage leaks and generate not only waste, but also accidents within the industrial environment.
Solution: preventing leaks resulting from loosening of the screws is essential. Through preventive measures, it is possible to perform periodic tightening and prevent this problem from happening to your pump. Depending on the case, it may be necessary to use reinforcement plates to provide additional support to the pump surface.
Faults on the retention valve
Check valve failures are also quite common in pneumatic diaphragm pumps. This failure can cause obstruction of the valve ball by objects or debris, causing the seal to be compromised. Fluid leak, which can impact not only the pump's results but also the productivity of your industry.
Solution: as in other cases, the solution to leaks caused by the check valve must be through a preventive approach, a filter can also be used to reduce obstruction and also carry out constant cleaning of the equipment.
