Abstract
The utility model relates to a shielded electric pump, which comprises a pump body and an impeller which is arranged in the pump body and sheathed on one end of a pump shaft; the other end of the pump shaft is connected with a rotor of a shielded motor and arranged in the motor via a bearing, the rotor and a stator of the motor are oppositely arranged, and a partition board is arranged between the rotor and the stator of the motor. The utility model is characterized in that the pump shaft is connected with one end of the rotor of the motor and provided with a ceramic ball or a pillar column bearing. The utility model solves the problems that radial force borne by the existing sliding bearing is small and the existing sliding bearing is easily worn and torn, so a friction and stator scrapping rotor phenomenon of the rotor and the stator is produced, which causes the damage of the electric pump. The utility model has the advantages of great bearing capability, high efficiency, high sealing performance, no dielectric leakage, low cost, etc.
Description
The utility model relates to a kind of electric pump, especially a kind of shielded electric-pump.
Shielded electric-pump has solved the problem that existing horizontal pump is easy to generate leakage up hill and dale, thereby is subjected to user's popular welcome.But owing between the motor stator of shielded electric-pump and the rotor intermediate isolating cover is installed, the space distance is very little between the two.Pump in the running, it is little to be assemblied in the radial force that the plain bearing on the pump shaft bears, and adds that wear resistance is relatively poor, the rotor tenesmus appears in motor easily, causes to produce mutual friction mutually between rotor and the stator and sweep the thorax phenomenon and damage electric pump.Sweep thorax in order to prevent from and to monitor to produce between rotor and the stator to rub, prior art need be provided with a cover supervisory system on shielded electric-pump.The corresponding electric pump manufacture cost that increased of this system.In addition, be balancing axial thrust, existing electric pump adopts the little plane thrust bearing of bearing capacity and offer the equalizing orifice mode on impeller, has also influenced the shielded electric-pump working efficiency.Because prior art exists above-mentioned defective, makes promoting the use of of this electric pump be subjected to certain limitation.
The utility model has overcome above-mentioned existing in prior technology shortcoming, and its purpose is to provide the shielded electric-pump that ceramic ball bearing or ceramics pole bearing are housed on a kind of pump shaft.
The utility model above-mentioned purpose realizes by following technological means.
A kind of shielded electric-pump, this electric pump comprises the pump housing and is loaded on the impeller that is sleeved on pump shaft one end in the pump housing, the other end of pump shaft is connected with the rotor of motor, the rotor and the stator of motor are oppositely arranged, be assemblied in motor field frame that the pump housing is connected in, be provided with intermediate clapboard between stator and the rotor, it is characterized in that said pump shaft be connected with the rotor of motor an end, be positioned at that the rotor both sides are equipped with ceramic ball or axis of a cylinder holds.
The ceramic ball of above-mentioned electric pump or axis of a cylinder bearing sleeve are contained on the pump shaft, are packed on the forward and backward two ends of the housing end cap of motor.
The utility model bearing radial force is big, wear resistance good, long service life, good leak tightness, no dielectric leakage, can start at full capacity, is suitable for fields such as oil, chemical industry, military project, food, pharmacy, uses as the electric pump of electromechanical integration.Owing to ceramic ball is housed on the pump shaft or axis of a cylinder holds, be used for substituting existing glide bearing or plane thrust bearing, so increased bearing capacity and self-lubricating property greatly, solved mutual friction mutually between rotor and the stator, produce and sweep the thorax phenomenon and damage the electric pump problem.And can remove one and be set on the shielded electric-pump anti-sweep thorax supervisory system, the corresponding electric pump manufacture cost that reduced.In addition, this electric pump has been cancelled the equalizing orifice of offering on the impeller, helps improving the working efficiency of shielded electric-pump.
Introduce the utility model specific embodiment in detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
A kind of shielded electric-pump, this electric pump comprises the pump housing 9 and is loaded on the impeller 10 in the pump housing 9, the end that impeller 10 is packed in pump shaft 3, the other end of pump shaft 3 is connected with the rotor of motor 5, the rotor 5 and the stator 4 of motor are oppositely arranged, be assemblied in the motor field frame 8 that is connected with the pump housing 9, be provided with intermediate clapboard 7 between stator 4 and the rotor 5.Be connected, be positioned on the pump shaft 3 of rotor 5 both sides with the rotor 5 of motor and be equipped with ceramic ball bearing 2, perhaps the ceramics pole bearing 2.Above-mentioned ceramic bearing 2 is sleeved on the pump shaft 3, is packed on the forward and backward end cap 1 in housing 8 two ends of motor.
