Abstract
The utility model relates a centrifugal pump bearing, whose temperature can be measured in an online manner. The bearing is a rolling bearing or a sliding bearing, and is sleeved on a shaft of a centrifugal pump. The bearing includes a bearing pedestal, a bearing cap, a bearing body and a bearing cover. An interface of temperature measuring device is formed on the bearing body or the bearing cap, and a temperature sensor is arranged in the interface. Compared with the prior art, the centrifugal pump bearing is provided with the interface of the temperature measuring device, a deep hole for mounting the temperature sensor is close to the surface of the bearing, the temperature sensor can get close to the bearing to the maximum, the temperature sensor can actually reflect the actual temperature of the bearing; and the temperature sensor can measure the bearing temperature always in the online manner, and measured temperature signals are sent to a user control terminal through the temperature sensor, so that the bearing temperature can be monitored uninterruptedly and continuously in the online manner.
Description
Technical field
The utility model relates to a kind of centrifugal pump bearing, but especially relates to a kind of centrifugal pump bearing of temperature measurement on-line.
Background technique
Bearing is to be used for the supporting rotor part, and bears the various load that act on the rotor component.Bearing is divided into sliding bearing and rolling bearing.The bearing of centrifugal pump plays crucial effects to the safety and steady operation of centrifugal pump.
The bearing part of general centrifugal pump is made up of parts such as bearing support, bearing cap, bearing, bearing glands.Centrifugal pump all requires the maximum temperature of bearing to be not more than 75 ℃ in running, and bearing temperature must not be than environment temperature above 35 ℃.During existing centrifugal pump bearing Component Design, mainly consider the interpolation problem of lubricant oil, and do not consider the thermometric problem of bearing, so, the interface of temperature measuring equipment all do not established on bearing support and the bearing gland.
Existing centrifugal pump in use because bearing part does not have the temperature measuring equipment interface, during thermometric, generally all is to use hand-held thermoscope to carry out stage and is interrupted thermometric.There is very big defective in this way:
(1) hand-held thermoscope can only measure the temperature of bearing support or bearing cap, and can't reflect the true temperature of bearing;
(2) use hand-held thermoscope can only carry out stage and be interrupted thermometric, can't carry out online all the time lasting thermometric;
(3) hand-held thermoscope can only on-the-spot thermometric, can't carry out the signal transmission, can not transmit signals to central control chamber or other control terminal, thus when bearing temperature above can not alert always when requiring.
Summary of the invention
But the purpose of this utility model is exactly to provide a kind of centrifugal pump bearing that reflects the true temperature of bearing truly and continue the temperature measurement on-line of uninterrupted on-line monitoring bearing temperature for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
But a kind of centrifugal pump bearing of temperature measurement on-line, this bearing is rolling bearing or sliding bearing, be set on the axle of centrifugal pump, comprise bearing support, bearing cap, bearing volume bearing gland, it is characterized in that, beginning temperature measuring equipment interface is provided with temperature transducer in this interface on the bearing support of this bearing or the bearing cap.
Described temperature transducer is connected with the control terminal signal.
Compared with prior art, the utility model is offered the temperature measuring equipment interface, temperature sensor mounted deep hole is near bearing surface, temperature transducer can be to greatest extent near bearing, so can reflect the true temperature of bearing comparatively truly, the serviceability temperature sensor can online all the time detection bearing temperature, and by temperature transducer detected temperature signal is sent to user control terminal, reaches to continue uninterrupted on-line monitoring bearing temperature.
