Abstract
The utility model provides a sand-proof device of a submersible motor. The submersible motor is provided with a motor seat; the motor shaft extends out of the motor seat; the surface of the motor shaft is sheathed with a sand throwing ring; and a shaft sealing pad and an oil seal are arranged between the motor shaft and the motor seat in sequence along the axial direction. The sand-proof device is characterized in that a dustproof gland is also arranged between the motor shaft and the motor seat; and the dust-proof gland is sheathed on the surface of the motor shaft and seals a gap between the motor shaft and the motor seat. Compared with the existing sand-proof device, the sand-proof device is additionally provided with a sand-proof gland, thus being capable of preventing fine sand from entering the shaft sealing pad and the oil seal more effectively, reducing the probability of fault occurrence and prolonging the service life of the equipment.
Description
Technical field
The utility model relates to a kind of sand prevention device, particularly the improvement that the sand prevention device of submersible motor is made.
Background technique
Submersible pump is a kind of purposes water treatment instrument very widely.What submersible pump was different with common suction engine is that it is operated under water, and suction engine is worked on the ground mostly.Submersible pump predominant use and Applicable scope comprise that construction construction row, water agricultural drainage and irrigation, industry water circulation, urban and rural residents quote the water supply, even rescue and relief work or the like.Because submersible pump is to work under water, so waterproof is extremely important.Owing to use under water for a long time, so the submersible motor of submersible pump needs the sand prevention device.Existing sand prevention device has only existing submersible motor generally to have only along sand-throwing ring, shaft sealing pad, the oil sealing of the axial setting of the motor shaft of submersible motor with sand control installation.Get rid of husky ring and motor shaft interlock, along with motor for submerged pump axle high speed rotating is thrown the grains of sand away, shaft sealing pad and oil sealing are in order to prevent that sealing and fine sand enter submersible motor inside.But the unreasonable structure of this sand prevention device, the grains of sand that can't get rid of can enter motor internal from shaft sealing pad and oil sealing.When motor shaft rotated, the fine sand and the motor shaft that enter shaft sealing pad and oil sealing rubbed, and made motor shaft, oil sealing wearing and tearing, scratched, and influenced electrical machinery life.
The model utility content
At defective that exists in the prior art and deficiency, the purpose of this utility model is the sand prevention device that proposes a kind of submersible motor, can prevent effectively that the grains of sand from entering the oil sealing of submersible motor, improves the Security and the working life of motor.
In order to achieve the above object, the utility model proposes a kind of sand prevention device of submersible motor, described submersible motor is provided with motor cabinet, motor shaft stretches out described motor cabinet, described motor shaft surface is socketed with gets rid of husky ring, is provided with shaft sealing pad, oil sealing between described motor shaft and the motor cabinet vertically successively, it is characterized in that, also be provided with dustproof gland between described motor shaft and the motor cabinet, described dustproof gland is socketed on described motor shaft surface and seals space between described motor shaft and the motor cabinet.
Preferred as technique scheme also comprises sponge mat, and described sponge mat is arranged between described dustproof gland and the described shaft sealing pad.
The utility model proposes a kind of sand prevention device of submersible motor, described submersible motor is provided with motor cabinet, motor shaft stretches out described motor cabinet, described motor shaft surface is socketed with gets rid of husky ring, be provided with shaft sealing pad, oil sealing between described motor shaft and the motor cabinet vertically successively, it is characterized in that, also be provided with dustproof gland between described motor shaft and the motor cabinet, described dustproof gland is socketed on described motor shaft surface and seals space between described motor shaft and the motor cabinet.The sand prevention device of the submersible motor that the utility model proposes, the existing sand prevention device of comparing is set up a sand prevention gland, can more effectively prevent that like this fine sand from entering shaft sealing pad and oil sealing, reduces the fault odds, improves the life-span of equipment.
Description of drawings
Fig. 1 is the sectional structure schematic representation of preferred embodiment of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The utility model preferred embodiment as shown in Figure 1, submersible motor is provided with motor cabinet 8, motor shaft 3 stretches out described motor cabinet 8, and described motor shaft 3 surfaces are socketed with gets rid of husky ring 1, is provided with shaft sealing pad 4, oil sealing 6, oil sealing 7 between described motor shaft 3 and the motor cabinet 8 vertically successively.Also be provided with dustproof gland 2 between described motor shaft 3 and the motor cabinet 8, described dustproof gland 2 is socketed on described motor shaft 3 surfaces and seals space between described motor shaft 3 and the motor cabinet 8.Can prevent effectively that like this fine sand from entering shaft sealing pad 4, oil sealing 6, oil sealing 7, improve the life-span of motor.Between sand prevention gland 2 and shaft sealing pad 4, also be provided with sponge mat 5 with buffering.
Certainly; the utility model also can have other embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; the person of ordinary skill in the field works as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of claim of the present utility model.
Claims (2)
1. the sand prevention device of a submersible motor, described submersible motor is provided with motor cabinet, and described motor shaft stretches out described motor cabinet, and described motor shaft surface is socketed with gets rid of husky ring, is provided with shaft sealing pad, oil sealing between described motor shaft and the motor cabinet vertically successively; It is characterized in that, also be provided with dustproof gland between described motor shaft and the motor cabinet, described dustproof gland is socketed on described motor shaft surface and seals space between described motor shaft and the motor cabinet.
