Abstract
A kind of Seal Kit for oscillating column pump includes the sphere as check-valves after C-shaped ring and the plunger on pump plunger as gasket, and the wherein C-shaped ring is made of the PTFE filled with glass fibre, and sphere is made of ceramet.The use of these materials increases at least five times of seal life, therefore increases the maintenance of oscillating column pump and replace the cost of the maintenance and the replacement that are spaced and reduce oscillating column pump.
Description
Technical field
The present invention relates to a kind of Seal Kit for oscillating column pump, has the characteristics that comparable innovation and beneficial.
Background technology
Oscillating column pump, the equipment for especially being used to conveying and selling beverage, such as automatic percolation type coffee pot and hot drink and/or cold
Vending machine is drunk, when being especially mounted in industry or commercial company or public building, is all run many times daily, therefore all
Component is all answered sturdy and durable.
More specifically, the stress alternation movement (50/60Hz) of plunger keeps sealing element easy to wear, to the normal operation of pump
It is far-reaching.For this reason, the average life span of these sealing elements ensures about 18000 operation weeks by pumping manufacturer
Phase is approximately corresponding to operation in 1 year, this is equal to interval expeced time between scheduled maintenance operation twice.
Stop the inconvenience bringing with equipment in view of being continuously increased for maintenance cost, makes troubles and equipment management people to user
The problem of loss of member, manufacture long-life oscillating column pump, is particularly critical, therefore firstly the need of with reliable and durable sealing element, permits
Permitted to greatly prolong the interval between attended operation twice.
Invention content
Therefore, applicant carefully studies and solves this very well by designing material composition appropriate for these sealing elements
Problem, these sealing elements pump five times of ordinary life accelerating to show during artificial ageing to be suitable for improving, extend close
The average life span of sealing runs to 90000 operations from described 18000 times, corresponds roughly to five operation years, new to generate
The long-life oscillating column pump of a generation, it is only necessary to carry out full maintenance operation in every 5 years.
These sealing elements are suitable for pump plunger, ensure the fluid sealability in the channel that diameter is about 5 millimeters, to make
Their material must have excellent durability and intensity although having small size and thickness.
These sealing elements include C-shaped ring, are used as the plunger sealing made of glass fibre filling PTFE (polytetrafluoroethylene (PTFE))
It is used as the sphere of check-valves after pad and plunger, the sphere is made of aluminium oxide or similar ceramet.
PTFE composite for C-shaped ring liner is used exclusively for the material of this purposes, it is 30 to 80 by containing length
What the pure PTFE of the glass fibre of micron was extruded from.Fiber glass packing can change to 25% by weight from 5%, therefore multiple
Condensation material may include 95%~75% PTFE and 5%~25% glass fibre, and preferred formula is average assay 85%
The glass fibre of PTFE and 15%.
Description of the drawings
Below in subsidiary attached drawing, only illustrates but be not limited to these examples:
Fig. 1 is the position for sealing C-shaped ring 10 on plunger P in the oscillating column pump of conventional type and the sphere as check-valves
20。
Fig. 2 is the enlarged cross sectional views of C-shaped ring 10, and two circular edges 12 define the outer ring that can place conventional spacers
14。
Specific implementation mode
According to the type of oscillating column pump, it is possible to understand that the accurate diameter of sealing element and position can be changed, close for manufacturing
The material of sealing should all use according to the law of implementation, regulation and specification and be suitable for the ingredient that food contacts compatibility.
Claims (according to the 19th article of modification of treaty)
1. a kind of Seal Kit for oscillating column pump, it is included in gasket (10) between pump sleeve and pump plunger (P) and in column
Fill in the check-valves (20) after (P), which is characterized in that the gasket (10) is defined by two circular edges (12) can place tradition
The C-shaped ring of the outer ring (14) of gasket is constituted, which is the sphere of ceramet.
2. external member according to claim 1, wherein C-shaped ring (10) by be 30 to 80 microns containing length range glass fibre
What PTFE was extruded from, include the glass fibre of by weight 95%~75% PTFE and weight ratio 5%~25%.
3. the material of external member according to claim 2, wherein C-shaped ring (10) by 85% PTFE and 15% glass fibre group
At.
4. the external member of aforementioned any claim, wherein the check-valves (20) is made of aluminium oxide.
Claims (5)
- Include being used as only after C-shaped ring and the plunger on pump plunger as gasket 1. a kind of Seal Kit for oscillating column pump Return the sphere of valve, which is characterized in that the C-shaped ring is made of the PTFE of filled glass fiber, which is made of ceramet.
- 2. external member according to claim 1, the wherein material of C-shaped ring by be 30 to 80 microns containing length range glass fibre What PTFE was extruded from, include the glass fibre of by weight 95%~75% PTFE and weight ratio 5%~25%.
- 3. external member according to claim 2, the wherein material of C-shaped ring are made of 85% PTFE and 15% glass fibre.
- 4. the external member of aforementioned any claim, the wherein sphere are made of aluminium oxide.
- 5. the sealing element external member of aforementioned any claim, wherein the service life of sealing element made of the material at least increases by five Times, correspondingly increase the service intervals of oscillating column pump and reduces the maintenance cost of oscillating column pump.
