Abstract
The utility model relates to an automatic balanced pressure regulating device for a submersible pump, belonging to a device which uses the function of an elastic component to cause pressure inside and outside of a seal cavity to be balanced. The utility model is formed by that the seal cavity is provided with a hole; a respirator made of elastic material is arranged on the hole; the outer side of the respirator is provided with a press cover with a bowl-shaped structure; the press cover is provided with an air outlet hole. Owing to the function of the respirator, the utility model avoids the defect that the service life of a complete machine is reduced by that a sealing member is damaged due to unbalanced pressure inside and outside of the seal cavity. With the device, the service life of the complete machine is extended severalfold above, generally reaching 7000 hours. The utility model has the advantages of simple structure, convenient installation and operation, low cost, etc.
Description
The utility model relates to a kind of submersible pump self-balancing pressure controlling device, belongs to prevent on the mechanical encapsulation devices that the interior Lubricants of Seal cage from leaking and the external agency leakage enters motor, keeps the self balancing a kind of device of Seal cage external and internal pressure.
This controlling device of structure described in the utility model is not installed on the submersible pump at present as yet, thereby cause and enter medium in the Seal cage, and make Sealing itself can not keep long drain oil lubricated, cause the Sealing damage and external agency is entered in the motor, cause burn-down of electric motor, reduce the working life of complete machine.
The purpose of this utility model is exactly in order to overcome above-mentioned deficiency of the prior art, and provides a kind of and can make the Seal cage external and internal pressure keep balance, improves the complete machine submersible pump self-balancing pressure controlling device in working life.
The purpose of this utility model is achieved in that it is made up of resuscitation apparatus, gland, set screw.Have the hole on the Seal cage, the resuscitation apparatus of being made by elastic material is installed on the hole, there is bowl-shape gland in this resuscitation apparatus outside by screw, and an air outlet hole is set on the gland.The utility model relies on resuscitation apparatus to regulate the Seal cage internal pressure automatically.
The utlity model has following advantage and good effect:
Because the resuscitation apparatus made from elastic material can be regulated the pressure inside and outside the Seal cage automatically, thereby avoided because the defective that the machine life that pressure imbalance damages Sealing itself to be caused descends, adopt this device back can improve more than several times working life, generally can reach more than 7000 hours, this device has characteristics simple in structure, that cost is low, easy for installation simultaneously, therefore has the suitable market competitiveness.
The explanation of accompanying drawing drawing
Accompanying drawing is the novel structural representation of this reality.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
In seal element (7) periphery Seal cage (1) is set, Seal cage has the hole on (1), resuscitation apparatus (2) is installed on the hole, resuscitation apparatus of the present utility model (2) is made by rubber material, be bowl structure, this resuscitation apparatus (2) outside is fixed with bowl-shape gland (4) by screw (6), and an air outlet hole (5) is set on the gland (4).Resuscitation apparatus (2) connects the space that forms a sealing with Seal cage (1), and lubricant oil (3) is enclosed in the Seal cage (1).When pump operation, because Sealing (7) friction itself and machine operation produce heat, cause the interior lubricant oil of Seal cage (1) (3) temperature to rise, volume increases, increased pressure, higher more than 2 times than external pressure, at this moment liquid leaks from the surface of contact of seal element (7) position own owing to the effect of increased pressure, at this moment resuscitation apparatus (2) is started working, increase Seal cage (1) space gradually, Seal cage (1) internal pressure also descends thereupon, thereby reach Seal cage (1) internal and external pressure balance, because the actuating range of resuscitation apparatus (2) own is bigger, it is just very high to adjust pressure range, when water pump shuts down, when reaching natural temperature, resuscitation apparatus (2) returns to original form again under the effect of elastic force.
Claims (2)
1, a kind of submersible pump self-balancing pressure controlling device, comprise seal element, Seal cage, Lubricants, it is characterized in that having the hole on the Seal cage, the resuscitation apparatus of being made by elastic material is installed on the hole, there is bowl-shape gland in this resuscitation apparatus outside by screw, and an air outlet hole is set on the gland.
2, submersible pump according to claim 1 self-balancing pressure controlling device is characterized in that resuscitation apparatus made by rubber material, is bowl structure.
