Abstract
The utility model relates to a mechanical sealed cooling body, concretely speaking, a mechanical seal cooling body for water cooling on sealed cavity of installation machines, comprising an inner shell (1), an outer shell (3). A sealed cooling cavity (6) formed by the inner shell (1) and the outer shell (3) is provided with a clapboard (11). A sealed passage (10) is arranged on an inlet (8) of cooling water. The cooling water of the utility model can flow only along flexuous passage, do better cooling on mechanical sealed cavity and improve the cooling result of the mechanical sealed cooling body. The utility model has the advantages that the improvement of cooling efficiency of the mechanical sealed cooling body can effectively reduce the temperature inside the mechanical sealed cavity, prolong the service life of the mechanical sealed body, reduce the maintenance quantity and failure rate of the equipment, save a great deal of stopping cost, spare part cost and maintenance cost, so that the utility model has great social and economic benefits.
Description
Technical field
The utility model relates to a kind of mechanical seal cooling case, specifically the cavity that mechanical seal is installed is carried out the mechanical seal cooling case of water flowing cooling.
Background technique
The mechanical seal of prior art directly is contained in the Seal cage of the pump housing, utilizes the cooling case of the cooling case of water pump as mechanical seal.After external cooling water directly enters the cooling chamber of cooling case, discharge from the outlet of cooling case again.In the cooling chamber of existing cooling case, do not have dividing plate, cooling water directly advances directly, and can not cool off mechanical seal well, and cooling effect is also bad.
The model utility content
The purpose of this utility model is the problems referred to above that exist at existing mechanical sealing cooling case, provides a kind of cooling effect better mechanical seal cooling case.
The purpose of this utility model is achieved in that
A kind of mechanical seal cooling case has frame, inner housing, dividing plate is arranged, the Packed passage in the cooling water inlet in the airtight cooling chamber that is made up of frame and inner housing; Dividing plate has breach, adjacent dividing plate can have breach in position inequality, the gateway of cooling water, passage by dividing plate and sealing separates, the passage of dividing plate and sealing will seal cooling chamber and separate to become tortuous passage, and cooling water inlet, coolant outlet are separated becomes the turnover of tortuous passageway port; The passage of sealing can an inner end through to cooling chamber; Can seal with " O " shape seal ring and " O " shape seal ring between inner housing and the frame.
Advantage of the present invention is:
1, between the inner housing and frame of mechanical seal cooling case, forms an airtight cooling chamber.Cooling water arrives the inner end of cooling chamber from the inlet of mechanical seal cooling case always by the passage of sealing.
2, have the dividing plate of breach in different positions, cooling chamber is separated into tortuous passage, the capacitor that a plurality of complications that passage that the gateway of mechanical seal cooling case is sealed and dividing plate are formed communicate separates, cooling water can only be along the channel flow of complications, can cool off the mechanical seal cavity better, improve the cooling effect of mechanical seal cooling case.
3, because the raising of the cooling effectiveness of mechanical seal cooling case; can reduce the temperature in the mechanical seal cavity effectively; the working life of prolonged mechanical sealing; the amount of maintenance of minimizing equipment and rate of fault; save a large amount of idleness expenses, spare part expense and maintenance expenses, huge social benefit and economic benefit are arranged.
Description of drawings
Fig. 1 is the structural representation of mechanical seal cooling case.
Fig. 2 is the inner housing structural representation.
Fig. 3 is the plan view of inner housing structure (Fig. 2).
Fig. 4 is the left view of inner housing structure (Fig. 2).
Embodiment
The mechanical seal cooling case is shown in Fig. 1～4, and inner housing 1 and frame 3 usefulness screws 5 connect into an integral body, forms the mechanical seal cooling case.With " O " shape seal ring 2 and 4 sealings of " O " shape seal ring, form an airtight cooling chamber 6 between inner housing 1 and the frame 3; The endoporus of inner housing 1 is exactly the mechanical seal cavity 7 that mechanical seal is installed; Cooling water inlet 8 and coolant outlet 9 are arranged on the end face of inner housing 1; The path 10 of the sealing in cooling water inlet 8 and the sealed chamber 6 links to each other, and coolant outlet 9 links to each other with cooling chamber 6 little cavitys interior, that separated by dividing plate 11; Packed path 10, several dividing plates 11 and adjacent dividing plate are at locational breach 12 inequality in cooling chamber 6, on the outer round surface of inner housing 1.
Cooling water arrives the inner end of cooling chamber 6 by the path 10 of cooling water inlet 8 by sealing always, then along being flowed out by coolant outlet 9 by the 12 formed tortuous passageway of the breach on dividing plate 11 and the dividing plate.
Claims (5)
1, a kind of mechanical seal cooling case, have inner housing (1), frame (3), it is characterized in that: dividing plate (11) is arranged, (8) Packed passage (10) in the airtight cooling chamber (6) that forms by frame (3) and inner housing (1) in the cooling water inlet.
2, according to the described mechanical seal cooling case of claim 1, it is characterized in that: dividing plate (11) has breach (12).
3, according to the described mechanical seal cooling case of claim 2, it is characterized in that: adjacent dividing plate (11) has breach (12) in position inequality, the passage (10) of dividing plate (11) and sealing will seal cooling chamber (6) and separate to become tortuous passage, and cooling water inlet (8), coolant outlet (9) are separated becomes the turnover of tortuous passageway port.
4, according to the described mechanical seal cooling case of one of claim 1～3, it is characterized in that: passage (10) one the inner ends of sealing through to cooling chamber (6).
5, according to the described mechanical seal cooling case of claim 1, it is characterized in that: seal with " O " shape seal ring (2) and " O " shape seal rings (4) between inner housing (1) and the frame (3).
