Abstract
The utility model discloses a flushing device of mechanical seal for a high pressure pump, which comprises a flushing pipe. Two ends of the flushing pipe are respectively fixedly connected in a sealing mode with a water pumping chamber in a spiral casing and a mechanical seal flushing cavity of a pump cover. The flushing pipe includes fixed flushing pipes at two ends and a detachable flushing pipe in the middle. The detachable flushing pipe is a corrugated hose. A throttle orifice is preset in the detachable flushing pipe and can reduce the impact of the flushing liquid on the mechanical seal, thereby prolonging service life of a mechanical seal device. The detachable flushing pipe in the middle of the flushing pipe is more convenient to install, dismount and change so that mechanical seal flushing pipe is convenient to washing and maintain, and maintenance cost is reduced.
Description
Technical field
The utility model relates to a kind of Rinsing unit, relates in particular to a kind of Rinsing unit of high pressure mechanical seal for pump.
Background technique
The Rinsing unit of existing high pressure mechanical seal for pump is to wash between the chamber with pumping chamber and pump cover machine envelope that cleaning hose directly welds or is threaded in the spiral case.
Wherein, welding manner can't add restricting orifice, therefore can't reduce the impact of washing solution to the machine envelope.
Though thread connecting mode can add restricting orifice, adopt hard the connection because of the two ends of cleaning hose, screw thread is killed easily during dismounting, causes dismantling maintenance difficult, the cleaning operation inconvenience.
The model utility content
The utility model provides a kind of Rinsing unit of high pressure mechanical seal for pump at the drawback of prior art.
The Rinsing unit of high pressure mechanical seal for pump described in the utility model, comprise two ends respectively with spiral case in pumping chamber and the cleaning hose that is connected of pump cover machine envelope flushing chamber sealing, described cleaning hose comprises the fixedly cleaning hose at two ends and the detachable cleaning hose at middle part, this detachable cleaning hose is a corrugated flexible hose, and restricting orifice is preset in its inside.
In the Rinsing unit of high pressure mechanical seal for pump described in the utility model, the detachable cleaning hose at described middle part is connected with the flange that fixedly adopts between the cleaning hose at two ends.
In the Rinsing unit of high pressure mechanical seal for pump described in the utility model, the restricting orifice that presets in the cleaning hose can reduce the impact of washing solution to the machine envelope, the working life of prolonged mechanical seal arrangement; The detachable cleaning hose at middle part adopts corrugated flexible hose, is convenient to more install, dismounting and changing, and is convenient to clean and servicing machine is sealflushed pipeline, the reduction maintenance cost.
Description of drawings
Fig. 1 is the structural representation of the Rinsing unit of high pressure mechanical seal for pump described in the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, can implements according to this with reference to the specification literal to make those skilled in the art.
As shown in Figure 1, the Rinsing unit of high pressure mechanical seal for pump described in the utility model, comprise two ends respectively with spiral case in pumping chamber 5 and the cleaning hose that is connected of pump cover machine envelope flushing chamber 6 sealings, described cleaning hose comprises the fixedly cleaning hose 21 at two ends and the detachable cleaning hose 22 at middle part, this detachable cleaning hose 22 is a corrugated flexible hose, and restricting orifice is preset in its inside.Can adopt flange 3 to be connected between the detachable cleaning hose 22 at described middle part and the fixedly cleaning hose 21 at two ends.
In the Rinsing unit of high pressure mechanical seal for pump described in the utility model, the restricting orifice that presets in the cleaning hose can reduce the impact of washing solution to the machine envelope, the working life of prolonged mechanical seal arrangement; The detachable cleaning hose at middle part adopts corrugated flexible hose, is convenient to more install, dismounting and changing, and is convenient to clean and servicing machine is sealflushed pipeline, the reduction maintenance cost.
Although embodiment of the present utility model is open as above, but it is not restricted to listed utilization in specification and the mode of execution, it can be applied to the various fields of the present utility model that are fit to fully, for those skilled in the art, can easily realize other modification, therefore under the universal that does not deviate from claim and equivalency range and limited, the legend that the utility model is not limited to specific details and illustrates here and describe.
