Abstract
The utility model relates to a high temperature water pump sealing device, which consists of a shaft, a static sealing device that is arranged on the shaft near the motor end, dynamic sealing devices that are harnessed on the shaft in sequence near the static sealing device, an O-shaped sealing ring and a spring. Gap is arranged between the inner surface of the static sealing device and the dynamic sealing device and the shaft; the O-shaped sealing ring is pressed in a groove of the dynamic sealing device by the spring; the utility model is characterized in that the end, at which the O-shaped sealing ring is contacted with the shaft and the spring, is provided with a high-temperature-resistant sealing ring, so as to wrap the O-shaped sealing ring in the groove of the dynamic sealing device. The high temperature water pump sealing device of the utility model has simple structure, good sealing performance and relatively long service life, which can work continuously for a relatively long time.
Description
Technical field
The utility model relates to a kind of high-temperature water pump sealing apparatus.
Background technique
Hot water pump in the market adopts the conventional machinery Sealing mostly, insulation cover is set in the middle of the pump housing and the motor attachment portion, in the insulation cover air cooling equipment can be installed, and the high temperature water pump need adopt the heat insulation and cooling of outer water supply, the conventional machinery Sealing can not bear the pressure of water under the condition of high temperature, steam permeates machinery easily and is sealed into into heat insulation cooling layer, causes motor to be heated and can not continuous operation, and heat insulation cooling layer complex structure.There is a kind of its seal arrangement of high temperature water pump different at present with aforesaid water pump, can establish heat insulation cooling layer, it comprises axle, be set in the static seal on the axle, dynamic seal, O RunddichtringO and spring, moving, all gapped between the internal surface of static seal and the axle, internal surface at the dynamic seal the other end is provided with groove, spring is pressed on the O RunddichtringO in the groove of dynamic seal, blocked quiet, space between dynamic seal and the axle, make the sealing between static seal and the dynamic seal better simultaneously, such high-temperature water pump structure is simple, sealability is better than aforesaid water pump, but because that the O RunddichtringO is under the situation of high temperature and hydraulic pressure for a long time is aging easily, distortion, influence sealability, so the shortcoming one of this high temperature water pump is can not the long-time continuous workpiece, the 2nd, the working life of seal arrangement is shorter.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, good seal performance, the high-temperature water pump sealing apparatus that energy long time continuous working and working life are long.
For solving above-mentioned task, high-temperature water pump sealing apparatus of the present utility model comprises axle, is located at the static seal of a close motor side, be close to static seal and be set in dynamic seal, O RunddichtringO and spring on the axle successively, all gapped between the internal surface of dynamic and static Sealing and the axle, spring is pressed on the O RunddichtringO in the groove of dynamic seal, characteristics are to be provided with the refractory seal ring at described O RunddichtringO with the end face that axle contacts with spring, the O RunddichtringO are wrapped in the groove of dynamic seal.
Its feature is that also described static seal and dynamic seal adopt two kinds of materials, and is surrounded by the exotic material layer at the skin of static seal, and dynamic seal adopts pyrographite, and static seal adopts cemented carbide.
Adopt the high-temperature water pump sealing apparatus of this spline structure, because the refractory seal ring parcel that the O RunddichtringO is made by exotic material, high temperature and pressure no longer directly act on it, thereby make its long time continuous working also can not be out of shape, wear out; In addition, dynamic and static Sealing adopts different materials, and can turn round does not for a long time influence sealability; Therefore high-temperature water pump sealing apparatus of the present utility model has guaranteed water temperature more than 130 ℃ and favorable sealing property, and motor can work long hours under normal temperature, and water pump gland is prolonged working life.
Description of drawings
Fig. 1 is the structural representation of the utility model mode of execution.
Embodiment
As shown in the figure, high-temperature water pump sealing apparatus of the present utility model comprises axle 1, static seal 2, dynamic seal 3, O RunddichtringO 4, spring 5, exotic material layer 6 and refractory seal ring 7, static seal 2 is located at axle 1 near motor one end, dynamic seal 3 is placed on the axle 1 to be close to commentaries on classics and with static seal 2 with axle, all gapped between the internal surface of static seal 2 and dynamic seal 3 and the axle 1, the internal surface of dynamic seal 3 the other ends is provided with groove, O RunddichtringO 4 and dynamic seal 3 are coaxial and be located in the groove of this dynamic seal 3, refractory seal ring 7 tightly is placed on the axle 1 and O RunddichtringO 4 is wrapped in the groove of dynamic seal 3, spring 5 compresses refractory seal ring 7, refractory seal ring 7 has been blocked moving like this, space between static seal and the axle, also cut off the O RunddichtringO and contacted, simultaneously at the excellent sealing that keeps under the effect of spring 5 and O RunddichtringO 4 between static seal 2 and the dynamic seal 3 with the direct of high-temperature water.Static seal 2 adopts two kinds of different materials with dynamic seal 3, static seal 2 preferably adopts cemented carbide, dynamic seal 3 preferably to adopt pyrographite, also can guarantee good sealing between the two even work long hours like this, outer surface in static seal 2 is provided with exotic material layer 6, can intercept high temperature and be delivered on the motor.
