Abstract
The utility model relates to a mechanical seal flushing device and belongs to the field of mechanical seals. Because an existing flushing hole is too large, the internal pressure in a mechanical seal is too high and uneven in distribution and a sealing ring and other parts are prone to too fast abrasion. The mechanical seal flushing device comprises a pump end cap, a mechanical seal end cap, a mechanical seal flushing hole, a mechanical seal flushing pipe, a resistance part and a pore passage, wherein the mechanical seal end cap is arranged on the pump end cap, the mechanical seal flushing hole is formed in the mechanical seal end cap, the mechanical seal flushing pipe and the resistance part are arranged in the mechanical seal flushing hole, and the pore passage for liquid flow-through is arranged in the resistance part in the axial direction. Through the utilization of the mechanical seal flushing device, the flow and pressure for flushing the mechanical seal can be reduced, leakage caused by abrasions and ageing of mechanical sealing parts can be prevented or reduced, the internal pressure of the mechanical seal can be reduced, the pressure can be distributed evenly and the service life of equipment can be prolonged.
Description
Technical field
The utility model belongs to mechanical seal field, is specifically related to a kind of mechanical seal rinsing device.
Background technique
Mechanical seal refers to the device that prevents fluid leakage that keeps laminating relative sliding under the effect of hydrodynamic pressure and compensation mechanism elastic force (or magnetic force) and under the cooperation of auxiliary seal by least one pair of end face perpendicular to spin axis and form.And mechanical seal leakage is the universal phenomenon that pump apparatus exists, leakaging cause is also varied, analyzes reason more difficult, and replacing or maintenance not only spend substantial contribution, affect job schedule, and often do not reach ideal effect.
In the mechanical sealing structure for pump of the outer cleaning hose of typical band, high-pressure medium is by pump discharge, and the flushing hole on outer cleaning hose, gland is to mechanical seal internal cooling and rinse seal ring, returns pump impeller import low pressure place.
Mechanical seal manufacturing enterprise is cooling in order to ensure seal ring, that conventionally flushing hole is designed is larger, to ensure enough flows, by computer Simulation and practical proof, it is unnecessary doing so actual, especially revolution speed is high or while carrying normal temperature medium, less flow can be taken away fricative dynamic and static ring heat.Flushing hole is crossed conference and is made mechanical seal internal pressure excessive in addition, and skewness, easily causes seal wears too fast, not high enough at pump assembly precision, pump running vibration is large or O RunddichtringO is aging in the situation that, easily cause mechanical seal leakage.
Model utility content
For the defect existing in prior art, the purpose of this utility model is to provide a kind of mechanical seal rinsing device.This device can prevent from or reduce, because of mechanical seal parts depreciation, the aging leakage causing, meanwhile, reducing mechanical seal internal pressure, and pressure distribution is become evenly, extension device working life.
For reaching above object, the technical solution adopted in the utility model is: a kind of mechanical seal rinsing device, comprise pump end cap, be located at the mechanical sealing end cover on pump end cap, be located at the mechanical seal rinsing hole on mechanical sealing end cover and be arranged on the mechanical seal rinsing pipe in this mechanical seal rinsing hole, it is characterized in that: this device also comprises the resistance piece being arranged in described mechanical seal rinsing hole the duct that is axially arranged with liquid communication of described resistance piece.
Further, described resistance piece is arranged on the mechanical seal rinsing mouth place in described mechanical seal rinsing hole.
Further, described resistance piece is enclosed within the lower end of described mechanical seal rinsing pipe, and described mechanical seal rinsing pipe is pushed down described resistance piece.
Further, the size of described resistance piece changes according to the size in mechanical seal rinsing hole and required flushing flow rate.
Further, the part that described resistance piece is inserted in cleaning hose is cylindrical, and the internal diameter of its external diameter and cleaning hose matches.
Effect of the present utility model is: adopt device described in the utility model, by increasing resistance piece at mechanical seal rinsing mouth, reduce mechanical seal rinsing flow and pressure, can prevent or reduce because of mechanical seal parts depreciation, the aging leakage causing, meanwhile, can reduce mechanical seal internal pressure, make pressure distribution become even, improve mechanical seal operating conditions, extension device working life.
Accompanying drawing explanation
Fig. 1 is the structural drawing of a kind of mechanical seal rinsing device in the utility model embodiment;
Wherein: 1 pump end cap; 2 mechanical seal rinsing pipes; 3 resistance pieces; 4 mechanical sealing end covers.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
As shown in Figure 1, a kind of mechanical seal rinsing device described in the utility model, comprise pump end cap 1, be located at the mechanical sealing end cover 4 on pump end cap 1, be located at the mechanical seal rinsing hole on mechanical sealing end cover 4 and be arranged on the mechanical seal rinsing pipe 2 in this mechanical seal rinsing hole, this device also comprises the resistance piece 3 being arranged in described mechanical seal rinsing hole, the duct that is axially arranged with liquid communication of described resistance piece 3.
Wherein, mechanical seal rinsing device in present embodiment is connected to mechanical sealing structure for pump, on mechanical sealing structure for pump, there is a mechanical sealing end cover 4, mechanical seal rinsing hole is positioned on mechanical sealing end cover 4, and resistance piece 3 and mechanical seal rinsing pipe 2 are installed in mechanical seal rinsing hole.
Preferably, described resistance piece 3 is arranged on the mechanical seal rinsing mouth place in mechanical seal rinsing hole, the i.e. bottom in mechanical seal rinsing hole; Described resistance piece 3 is enclosed within the lower end of described mechanical seal rinsing pipe 2, and the part that resistance piece 3 is inserted in cleaning hose 2 is cylindrical, and the internal diameter of its external diameter and cleaning hose 2 matches.Mechanical seal rinsing pipe is pushed down resistance piece 3; The size of resistance piece 3 changes according to the size in mechanical seal rinsing hole and required flushing flow rate.
It should be noted that, in the utility model, the resistance piece 3 of indication can be any cut-off device, and object is to reduce mechanical seal rinsing flow and pressure.
When as installed, first the mechanical seal rinsing pipe 2 on mechanical seal rinsing hole is dismantled, then the resistance piece processing 3 is put in mechanical seal rinsing hole, again mechanical seal rinsing pipe 2 is reinstalled in mechanical seal rinsing hole, and push down resistance piece, in 1～2 people 30 minutes, can complete the installation of resistance piece, the size of resistance piece 3 and specification can change according to the size in mechanical seal rinsing hole and required flushing flow rate.While installing the operation of mechanical seal rinsing device, high-pressure medium is by pump discharge, and the mechanical seal rinsing hole on outer cleaning hose, end cap is to mechanical seal internal cooling and rinse seal ring, returns pump impeller import low pressure place.
Can find out by present embodiment, adopt device described in the utility model, by increasing resistance piece at mechanical seal rinsing mouth, reduce mechanical seal rinsing flow and pressure, can prevent or reduce because of mechanical seal parts depreciation, the aging leakage causing, simultaneously, can reduce mechanical seal internal pressure, pressure distribution is become evenly, improved mechanical seal operating conditions, extension device working life.
Device described in the utility model is not limited to the embodiment described in embodiment, and those skilled in the art draw other mode of execution according to the technical solution of the utility model, belongs to equally technological innovation scope of the present utility model.
