Abstract
The utility model discloses a silicon carbide mechanical seal device for industrial wastewater pump, comprising a seal moving ring (2) which sleeves and circumferentially defines a shaft sleeve (1), a seal static ring (4) which sleeves the shaft sleeve (1) and circumferentially defines a compressing cover (3), and a compression spring (5) disposed between the seal static ring (4) and the compressing cover (3). The seal static ring (4) is in a press fit with the seal moving ring (2) through the compression spring (5). A cooling loop which is communicated with a cooling medium source and is used for a seal grinding surface composed by the seal static ring (4) and the seal moving ring (2) is disposed on the compressing cover (3). The silicon carbide mechanical seal device has good sealing reliability, and effectively reduces device maintenance cost and manpower.
Description
Technical field
The utility model relates to the mechanical sealing technology field, specifically is a kind of industrial wastewater pump silicon carbide mechanical seal device.
Background technique
Present industrial wastewater pump with the silicon carbide mechanical seal device comprise socket and circumferentially spacing on axle sleeve the sealing rotating ring, be socketed on the axle sleeve and circumferentially spacing on gland stationary seal ring, be located at the holddown spring between stationary seal ring and the gland; Described stationary seal ring is force-fitted on the end face of sealing rotating ring through holddown spring.Sealing rotating ring in this structure rotates along with the rotation of pump shaft, and stationary seal ring forms the sealing flour milling with the sealing rotating ring and realizes pump inside and extraneous mechanical seal.
There is following shortcoming in the mechanical seal device of above prior art: because Industrial Wastewater Treatment engineering operating mode complexity, the impurity that industrial wastewater contains is many, particle is big, these impurity can form on the sealing flour milling with the sealing rotating ring at stationary seal ring and deposit, and the industrial wastewater pH value is strong, corrosivity is strong, the temperature height, this can directly influence stationary seal ring and form the sealing flour milling with the sealing rotating ring, more than these reasons all can make the sealing unreliable, poor stability, make mechanical seal lose efficacy easily, therefore need often to change the sealed member of mechanical seal device, increased equipment maintenance cost and manpower.
The model utility content
The technical problems to be solved in the utility model is, provide a kind of sealing reliability good, effectively reduce the industrial wastewater pump silicon carbide mechanical seal device of equipment maintenance cost and manpower.
The technical solution of the utility model is, a kind of industrial wastewater pump silicon carbide mechanical seal device with following structure is provided, comprise be socketed on the axle sleeve and circumferentially spacing on axle sleeve sealing rotating ring, socket and circumferentially spacing on gland stationary seal ring, be located at the holddown spring between stationary seal ring and the gland; Described stationary seal ring is force-fitted on the sealing rotating ring through holddown spring, and described gland is provided with the cooling loop that is communicated with and is used for the sealing flour milling of coolant seal stationary ring and the formation of sealing rotating ring with the cooling medium source.
Described cooling loop is meant, described gland is provided with liquid entering hole radially, the inwall of described gland is provided with the annular cooling inner chamber that the footpath concaves, and is provided with annular liquid outlet between described gland and the axle sleeve, is communicated with between described liquid entering hole, annular cooling inner chamber, the annular liquid outlet.
The height of described annular cooling inner chamber is outer short interior long.
After adopting said structure, the utility model compared with prior art, have the following advantages: because described gland is provided with the cooling loop that is communicated with and is used for the sealing flour milling of coolant seal stationary ring and the formation of sealing rotating ring with the cooling medium source, like this can be by other link to each other clean, the cooling medium source of low temperature enters from cooling loop one end, cooling forms the sealing flour milling at stationary seal ring and sealing rotating ring, can prevent also simultaneously that industrial wastewater from entering into stationary seal ring and sealing the sealing flour milling that rotating ring forms, the sealing flour milling of promptly avoiding direct contact seal stationary ring of industrial wastewater and sealing rotating ring to form, so just make sealing reliable, good stability, make that mechanical seal is difficult for losing efficacy, therefore need not often to change the sealed member of mechanical seal device, reduced equipment maintenance cost and manpower.
As improvement, described cooling loop is meant, described gland is provided with liquid entering hole radially, the inwall of described gland is provided with the annular cooling inner chamber that the footpath concaves, be provided with annular liquid outlet between described gland and the axle sleeve, be communicated with between described liquid entering hole, annular cooling inner chamber, the annular liquid outlet, this annular cooling inner chamber is coolant seal stationary ring and the sealing flour milling that the sealing rotating ring forms directly, makes the cooling loop good cooling results.
As improvement, the height of described annular cooling inner chamber is outer short interior long, is more prone to the inflow and the cooling of cooling medium like this.

Below in conjunction with accompanying drawing the utility model industrial wastewater pump is described further with the silicon carbide mechanical seal device.
As shown in the figure, industrial wastewater pump silicon carbide mechanical seal device of the present utility model, comprise socket and circumferentially spacing on axle sleeve 1 sealing rotating ring 2, be socketed on the axle sleeve 1 and circumferentially spacing on gland 3 stationary seal ring 4, be located at the holddown spring 5 between stationary seal ring 4 and the gland 3; Described stationary seal ring 4 is force-fitted on the sealing rotating ring 2 through holddown spring 5, it is characterized in that: described gland 1 is provided with the cooling loop that is communicated with and is used for the sealing flour milling of coolant seal stationary ring 4 and 2 formation of sealing rotating ring with the cooling medium source.
Described cooling loop is meant, described gland 3 is provided with liquid entering hole 6 radially, the inwall of described gland 3 is provided with the annular cooling inner chamber 7 that the footpath concaves, and is provided with annular liquid outlet 8 between described gland 3 and the axle sleeve 1, is communicated with between described liquid entering hole 6, annular cooling inner chamber 7, the annular liquid outlet 8.
The height of described annular cooling inner chamber 7 is outer short interior long, i.e. annular cooling inner chamber 7 is shorter than the other end near the end face height of liquid entering hole 6.
Cooling loop in use, the industrial wastewater pump can be selected supporting auxiliary system for use with the silicon carbide mechanical seal device, the cooling medium of auxiliary system successively by liquid entering hole 6, annular cooling inner chamber 7, be punched into the end face that contacts of sealing rotating ring 4 and stationary seal ring 5, finally from annular liquid outlet 8 outflows.
