Description

A kind of mechanical seal is from flushing filtering system

Technical field

The utility model relates to filtration system technical field, more particularly to a kind of mechanical seal from washing and filtering System.

Background technique

Mechanical seal rinsing containing solid medium needs the machinery for using clean oil product medium as scouring media to pump Sealing carries out collective's flushing, but too high in the scouring media price of some media, therefore the medium for using itself instead is situated between as flushing Matter, but itself medium solid content is relatively high (such as coal tar contains solid sump oil), it is necessary to it could be rushed into people's mechanical seal after filtering System is washed, uses single-filter in the past, requires that ability after pump switches will be run every time when filter differential pressure increases It is filtered the cleaning of device.

It is artificial clear that filter progress is split out after must first moving back the oil in flushing pipeline completely in filter scale removal process again It washes, is possible to not put it clean because of the oil in pipeline during tearing open and causes oil accident, or due to some valves leakages The accidents such as personnel's scald are caused when tearing filter screen open, and often cause filter damage in scale removal process, so that filtering effect Fruit is deteriorated, and solid matter enters mechanical seal and mechanical seal is caused to damage.

The filter of mechanical seal rinsing system used at present is single, and filter is wanted clear again after having blocked up The drawbacks of filter can only be split out cleaning by washing, and be done so mainly has some；

1, it is be easy to cause oil leak once not putting it clean the oil in pipeline before splitting out filter core, pollutes environment；

2, once have valves leakage may be because split out filter core during cause the injury of operator；

3, frequently disassembly filter core is easy to damage filter body or damage filter core, once filter core is damaged Filter effect, which is not achieved, to take solid matter in mechanical seal to, and mechanical seal is caused to damage；

4, filter core needs frequent cleaning when solid content is higher, this results in the frequent switching of pump, the machine directly shortened In the service life of pump and activation system, very big injury is caused to equipment.
