Abstract
The utility model provides an oil-water type motor protector for a high temperature resistant submersible pump. The oil-water type motor protector is characterized by comprising a connecting section, two guide pipes, a shaft-protecting sleeve pipe, a sealed shell, a bearing and a bearing seat. The connecting section is fixedly mounted on the upper end face of the sealed shell, the guide pipes are axially vertically mounted in the sealed shell, one upper end of one of the guide pipes penetrates through the sealed shell to extend into the connecting section while one lower end of the same is close to the bottom portion of the sealed shell, an upper end of the other guide pipe is close to the upper end face of the sealed shell while the lower end of the same penetrates out of the sealed shell, the shaft-protecting sleeve pipe is arranged at an axial center of the sealed shell, and the lower end of the shaft-protecting sleeve pipe is fixedly mounted on the sealed shell through the bearing seat while and the upper end of the same is sealedly connected with the upper end face of the sealed shell. The oil-water type motor protector for the high temperature resistant submersible pump has the advantages that internal and external pressure of the motor can be guarantee to kept in balance when the motor is working under water, and external water is blocked to enter an inner cavity of the motor so as to guarantee the motor to reliably operate in a complex environment.
Description
Technical field
The utility model provides a kind of high temperature resistant submersible pump with profit formula motor protecter, belongs to technical field of motors.
Background technology
The equipment that latent heat water power pump is pumped as BADIRE water can be in temperature stable operation below 80 ℃, and just poor in the lifetime stability of 80 ℃～100 ℃ scope internal latent heat water power pumps, the life-span that surpasses 100 ℃ of electric pumps shortens significantly.Along with life-span of the rising electric pump of temperature changes, mainly be that the life-span of the necessary electromotor of electric pump can't reliably guarantee.
The utility model content
The purpose of this utility model provides a kind of high temperature resistant submersible pump usefulness profit formula motor protecter that can overcome above-mentioned defective, guarantee motor reliability service when high temperature.Its technical scheme is:
A kind of high temperature resistant submersible pump profit formula motor protecter; it is characterized in that: comprise linkage section; two conduits; the protective shaft sleeve pipe; seal casinghousing; bearing; bearing pedestal; its middle connecting segment is fixedly mounted on the upper surface of seal casinghousing; two conduits are vertically mounted in the seal casinghousing vertically; and the upper end of a conduit is passed seal casinghousing and is probeed in the linkage section; the lower end is near the bottom of seal casinghousing; the upper end of another root conduit is near the upper surface of seal casinghousing; the lower end passes seal casinghousing; the protective shaft sleeve pipe is positioned at the axial centre of seal casinghousing; the lower end is fixedly mounted on the seal casinghousing through bearing pedestal, and the upper surface of upper end and seal casinghousing is tightly connected.
Its operation principle is: protector is installed on the output shaft of filled with oil formula motor, and seal casinghousing is filled oil.Motor can produce heat when work; internal volume expands; cause that inner oil overflows outward; enter in the seal casinghousing through conduit 1; oil in the seal casinghousing is upwards discharged seal casinghousing through conduit 2; till balance, when motor quit work, internal volume can dwindle; outside water is just in conduit 2 downward suction seal housings; form one deck water layer in the seal casinghousing bottom, because oil; water density there are differences, and water is always in the lower floor of oil; when motor is worked again, expand like this overflow just become water; what suck when motor is shut down also is water, has just formed one deck water conservation layer, thereby has played the purpose of protection motor.
The utility model compared with prior art, its advantage is: slip into when working in the water at motor, guarantee the motor internal and external pressure balance, also stop outside water to enter motor cavity simultaneously, thereby guarantee motor reliability service in complex environment.
Description of drawings
Fig. 1 is that the utility model embodiment is installed in the structural representation on the filled with oil formula motor output shaft.
Among the figure: 1, linkage section 2, conduit 3, protective shaft sleeve pipe 4, seal casinghousing 5, bearing 6, bearing pedestal 7, oil 8, water 9, output shaft.
Embodiment
In the embodiment shown in fig. 1: protector is installed on the output shaft 9 of filled with oil formula motor, fills oil 7 in the seal casinghousing 4.Linkage section 1 is fixedly mounted on the upper surface of seal casinghousing 4, two conduits 2 are vertically mounted in the seal casinghousing 4 vertically, and the upper end of a conduit 2 is passed, and seal casinghousing 4 probes in the linkage section 1, the lower end is near the bottom of seal casinghousing 4, the upper end of another root conduit 2 passes seal casinghousing 4 near upper surface, the lower end of seal casinghousing 4, protective shaft sleeve pipe 3 is positioned at the axial centre of seal casinghousing 4, the lower end is fixedly mounted on the seal casinghousing 4 through bearing pedestal 6, and the upper surface of upper end and seal casinghousing 4 is tightly connected.
