Abstract
A reciprocating type high-pressure water injection pump belt pulley supporting device comprises a belt pulley (1), an auxiliary bearing (2), an auxiliary bearing seat (3), a supporting shaft (4), a supporting seat (5) and a supporting shaft fixing bolt (6), wherein the auxiliary bearing (2) is installed in the belt pulley (1), the auxiliary bearing (2) is located on the auxiliary bearing seat (3), the auxiliary bearing (3) is installed at one end of the supporting shaft (4), the other end of the supporting shaft (4) is fixed on the supporting seat (5) through the supporting shaft fixing bolt (6), the adverse stress condition of bending moment borne by a motor shaft is relieved, and the adverse effect of plastic deformation on a bearing and a transmission shaft, which is originally generated after the small belt pulley is subjected to a large bending moment; after the transformation, the operation temperature of the front bearing of the motor can be greatly reduced, and the risk of breaking the motor shaft is eliminated.
Description
Technical field
The utility model is to be used for the motor fore bearing of reciprocating type high pressure water-injection pump and the protective gear of motor shaft, specifically, is a kind of reciprocating type high pressure water-injection pump small belt pulley support device.
Background technique
The more employing belt transmission of reciprocating type high pressure water-injection pump by the small belt pulley of motor shaft extension end and the big belt pulley on the pump power end, is turned round back front pump power end by belt with the power speed changing change.The direct result that belt transmissioning mode brought be exactly bigger radial force to the effect of motor shaft extension end, pump capacity is big more, radial force is just big more, the moment of flexure of being brought makes the unidirectional pressurized of motor bearings thus, cause operating conditions to worsen, the motor bearings lost of life, motor shaft fractures.
Xinjiang Oilfield branch company three factories, 103 water-injection stations that recover the oil, installation and operation in 2004 the reciprocating type high pressure water-injection pump of the big discharge capacity of 5ZB-20/43 type that one-tenth company develops in the huge port, 5 Tianjin, the Y400-6 315KW motor that it was equipped with was since 2005, occur frequently that front axle socket end temperature is too high, fore bearing damages and Accident due to quality such as axle fracture, after consulting several times with Jiamusi Electrical Machinery Plant of manufacturer, way is not well solved, decide from the water filling pump structure and set about, solve motor front axle socket end problem.
Summary of the invention
The purpose of this utility model is to provide a kind of reciprocating type high pressure water-injection pump small belt pulley support device, it is that a cover auxiliary support apparatus is installed on the reciprocating pump small belt pulley, improve motor front axle socket end operating conditions, prolong the motor fore bearing life-span, prevent the motor shaft accident that fractures, reduce the electrical fault rate.
The utility model is achieved in that and comprises small belt pulley, auxiliary bearing, auxiliary axis bearing, back shaft, supporting base, back shaft fixing bolt, auxiliary bearing is housed in the small belt pulley, auxiliary bearing is located on the auxiliary axis bearing, back shaft one end is installed auxiliary bearing, and the other end of back shaft is fixed on the supporting base by the back shaft fixing bolt.
The fixed support axle is fixedlyed connected with supporting base.
Have the bolt hole slotted hole on the supporting base.
The end bore hole of small belt pulley, auxiliary bearing, auxiliary axis bearing are installed in the hole.
Auxiliary bearing adopts inner ring single block border roller bearing.
The advantage of this model utility is: the small belt pulley support device is the improvement of structural type, make the force way of motor transmission shaft change simply supported beam into from overhang, both alleviated the bad force-bearing situation of the suffered moment of flexure of motor shaft, and eliminated and originally be subjected to the plastic deformation that produces after the big moment of flexure harmful effect bearing and transmission shaft; After the transformation, the operating temperature of motor fore bearing can be reduced significantly, has eliminated the risk that motor shaft fractures.At present just in Xinjiang Oilfield Company 103 water-injection station The field, though after transforming enforcement, the 20000 hours not enough time of industry operation, can infer that by the running temperature of present motor fore bearing can meet the demands the working life of motor bearings.
Reciprocating pump boundary dimension changes little, is particularly useful for the reciprocating type high pressure water-injection pump at scene is transformed.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
As shown in drawings, 1. small belt pulley, 2. auxiliary bearing, 3. auxiliary axis bearing, 4. back shaft, 5. supporting base, 6. back shaft fixing bolt, small belt pulley 1 is transformed lengthening, end bore hole at small belt pulley 1, auxiliary bearing 2, auxiliary axis bearing 3 are installed in the hole auxiliary bearing 2, employing inner ring single block border roller bearing.
Supporting base 5 is used for fixing back shaft 4, and back shaft 4 usefulness back shaft fixing bolts 6 are fixed on the supporting base 5, and the bolt hole on the supporting base 5 adopts slotted hole, makes the fixed position height of back shaft 4 on supporting base 5 adjustable.
Moment of flexure compares before and after transforming, and the ratio of moment of flexure is L2/L before and after transforming, and moment of flexure has reduced 1/2.
For prolonging the reciprocating type water injection pump motor bearings of big discharge capacity working life, reducing the electrical fault rate, use this device can satisfy usage requirement.
