Abstract
The utility model relates to a mechanical seal washing structure of a double suction pump and capable of filtering impurities, which comprises a double suction pump casing, a mechanical seal washing pipeline and filtering screens. The mechanical seal washing structure is characterized in that the filtering screens are installed at the position of a pump casing press out chamber and a mechanical seal washing pipeline inlet and the overflowing portion of mechanical seal chambers at two ends and a pump casing water inlet chamber, and the filtering screens are fixed on the double suction pump casing through rivets. The mechanical seal washing structure has the advantages of ensuring that the mechanical seal washing pipeline inlet cannot be blocked and ensuring cleaning of mechanical seal washing water. The filtering screens are installed on the overflowing portion of the mechanical seal chambers at two ends and the pump casing water inlet chamber and are capable of ensuring impurities not to enter the mechanical seal chambers. Due to the fact that the level gradually rises when the pump is started, the impurities in the media can enter the mechanical seal chambers if the two filtering screens are not installed. Due to installation of the filtering screen, the mechanical seal washing water can better lubricate and cool a mechanical seal, guarantees normal and stable working for the mechanical seal and enables the water pump to run stably.
Description
Technical field
The utility model relates to a kind of double suction pump machine envelope flushing mechanism that can impurity screening.
Background technique
Whether the quality of the runnability of the machine of double suction pump envelope directly has influence on whole unit and can run well, and this will assurance machine envelope sparge water constantly be lubricated the machine envelope and cools off.But owing to do not contain foreign material and dirt in the medium that is difficult to guarantee to carry; Impurity phenomenon of blocking in the machine envelope flushing line pump medium will appear when pump operation like this; Thereby just can not guarantee the lubricated and cooling of sparge water to the machine envelope; The life-span of machine envelope descends greatly, causes the maintenance rate of pump to increase, can't proper functioning.
Summary of the invention
The purpose of the utility model is to solve in the existing technology because machine envelope flushing line is stopped up the problems referred to above that cause by the impurity in the medium, provides a kind of double suction pump machine that can impurity screening to seal flushing mechanism.A kind of double suction pump machine envelope flushing mechanism that can impurity screening of the utility model; Comprise double suction pump pump case, machine envelope flushing line, filter screen; It is characterized in that: in pump case delivery chamber and machine envelope flushing line inlet and two ends sealing chamber and pump case intake chamber overcurrent filter screen is installed partly, filter screen is fixed on the double suction pump pump case by rivet.The utility model has the advantages that the import that has guaranteed machine envelope flushing line can not stop up, also guaranteed the cleaning of machine envelope sparge water; Filter screen is respectively installed with pump case intake chamber overcurrent part by sealing chamber at two ends, is that the page raises gradually because pump just starts, and the impurity in the medium also can enter into sealing chamber like this, this twice filter screen has been installed can have been guaranteed that impurity can not enter into sealing chamber.Because filter screen has been installed, machine envelope sparge water will better be lubricated the machine envelope and cool off, and normal, the stable operation that seal for machine provide assurance, and water pump is moved more stably.
Description of drawings
Fig. 1 stops up the schematic representation that the machine envelope can not normally be moved for original technological flushing line.
Fig. 2 is the structural representation of the utility model.
Among Fig. 1,11 are machine envelope flushing line, and 12 is sealing chamber, and 13 are obstruction place of machine envelope flushing line, and 14 is the pump case delivery chamber; 15 is the pump case intake chamber, and among Fig. 2,1 is machine envelope flushing line, and 2 is sealing chamber, and 3 is the pump case delivery chamber; 4 is the pump case intake chamber, and 5 is pump case, and 6 is filter screen, and 7 is rivet.
Below in conjunction with accompanying drawing and construction embodiment the utility model is made detailed operation instruction.
Embodiment
Comprise double suction pump pump case, machine envelope flushing line, filter screen among the figure, it is characterized in that: seal flushing line inlet and two ends sealing chamber and pump case intake chamber overcurrent at pump case delivery chamber and machine filter screen partly is installed, filter screen is fixed on the double suction pump pump case by rivet.Since pump case delivery chamber and machine seal flushing line inlet and two ends sealing chamber and pump case intake chamber overcurrent partly install can filter medium in the filter screen of impurity, filter screen is fixed on the pump case with rivet.Because the impurity of having installed in the filter screen medium can't seal flushing line by the entering machine, impurity is just taken away by the medium that constantly flows; When pump just started, liquid level raise gradually in the pump, because two ends sealing chamber and pump case intake chamber overcurrent have partly been installed filter screen, impurity can not enter into sealing chamber yet, and when pump normally moved, impurity will be sealed sparge water by high-pressure unit and wash away.Guaranteed the proper functioning of machine envelope, pump is moved more stably.
Claims (1)
