Abstract
The utility model discloses a sealer for a peripheral pump, which comprises a movable ring, a static ring and a sealing seat. A corrugated tube (2) is installed on a pump shaft (1), and is sheathed with a large spring (3). The movable ring (4) is embedded on and fixed on the corrugated tube (2). The corrugated tube (2) and the movable ring (4) are fixed on the pump shaft (1). The static ring (5) is fixedly arranged on a sealing seat (6). The corrugated tube (2) is embedded with and fixed with a friction pair (7). A contact surface is formed between the friction pair (7) and the static ring (5) to prevent the leakage of liquids. The utility model which adopts the structure improves the sealing performance of a mechanical sealer used for a peripheral pump, prolongs the service life, and stops the phenomena of 'loss', 'overflow ' and 'leakage' in the production section of a chemical enterprise. The utility model is a new energy saving and environment protection product.
Description
Technical field
The utility model relates to a kind of mechanical seal device, especially relates to a kind of mechanical seal device that is used for peripheral pump.
Background technique
Peripheral pump is a kind of low-flow high-lift chemical pump, is used for delivery temperature from-20 ℃-+80 ℃, and viscosity is not more than 5 , corrosivity and non-corrosive not solids-laden fluid.Main feature is the working pressure height and is used to have corrosive organic solvent.In the operation process of peripheral pump, for the flowing medium that stops conveying along the slot leakage between turning axle and the mechanical hull, sealing must be set.At present, like product general machine envelope in peripheral pump market is (interior dress) formula big spring or the bellows mechanical seal of outer dress, the fluorine rubber ring decay resistance that uses in these two kinds of machine envelope former structure is relatively poor, and the latter is skidded easily when working pressure envelope on high opportunity, and use condition is very undesirable.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of compact structure, the antileakaging mechanical seal device that is used for peripheral pump.
Technical problem to be solved in the utility model is achieved by the following technical solution: it comprises compositions such as rotating ring, stationary ring, sealing seat, and bellow is installed on pump shaft, is with big spring on the bellow.Rotating ring is embedded on the bellow, and bellow is fixed on the pump shaft together with rotating ring, and stationary ring is fixedly installed on the sealing seat.Be embedded on the described bellows and be fixed with friction pair, form surface of contact between friction pair and the stationary ring, to prevent leak of liquid.
The said structure that the utility model adopts has improved the sealability of the mechanical seal device that is used for peripheral pump, has prolonged working life, has stopped " race ", " emitting ", " dripping ", " leakage " phenomenon in the Production in Chemical Plant link.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Figure 1 shows that the structural drawing of peripheral pump
Figure 2 shows that peripheral pump mechanical seal device structural drawing
Embodiment
As shown in Figure 1, be used for the mounting point of the mechanical seal device of peripheral pump at peripheral pump.The structure of peripheral pump mechanical seal device as shown in Figure 2, it comprises compositions such as rotating ring, stationary ring, sealing seat, and bellow 2 is installed on pump shaft 1, is with big spring 3 on the bellow 2.Rotating ring 4 is embedded on the bellow 2, and bellow 2 is fixed on the pump shaft 1 together with rotating ring 4 usefulness thrust screws, and stationary ring 5 is fixedly installed on the sealing seat 6.Be embedded on the bellows 2 and be fixed with friction pair 7, form surface of contact between friction pair 7 and the stationary ring 5, to prevent leak of liquid.When peripheral pump turned round, liquid medium can be sealed at dynamic and static ring junction plane place, and the machining accuracy of dynamic and static ring is very high, and by the tension force of bellow 2, the dynamic and static ring junction plane can be pressed very tightly, thereby can not leak.Described rotating ring and stationary ring material are silicon carbide.Inevitably take off the liquid situation if having, also can add water-cooling apparatus on sealing seat 6 according to customer requirements, during running, dynamic and static ring can be generated heat, can be by the cooling of the water-cooling apparatus on the sealing seat 6.Permission user serviceability temperature can be up to 150 ℃ after adding cooling water.After operation after a while, dynamic and static ring can be worn, but can compensate automatically by the tension force of bellow 2.
Claims (4)
1, a kind of peripheral pump seal arrangement comprises rotating ring, stationary ring, sealing seat, it is characterized in that bellow (2) is installed on pump shaft (1), is with big spring (3) on the bellow (2).
2, peripheral pump seal arrangement according to claim 1 is characterized in that rotating ring (4) is embedded on the bellow (2), and bellow (2) is fixed on the pump shaft (1) together with rotating ring (4), and stationary ring (5) is fixedly installed on the sealing seat (6).
3, peripheral pump seal arrangement according to claim 1 is characterized in that being embedded on the bellows (2) and is fixed with friction pair (7), forms surface of contact between friction pair (7) and the stationary ring (5), to prevent leak of liquid.
4, peripheral pump seal arrangement according to claim 1 is characterized in that described rotating ring and stationary ring material are silicon carbide.
