Exempt-maintenance self-lubricating bearing apparatus of water turbine for cooling tower

Abstract

The invention relates to a hydraulic turbine maintenance free self lubricating bearing device for cooling tower, comprising an engine seat, an impeller, a water inlet, an axis, wherein the impeller is connected with the axis by screw thread. The device is characterized in that: the engine seat is connected with the bearing block by screw thread to form a shell, the impeller is arranged inside the shell, an upper shaft sleeve and a lower shaft sleeve are arranged inside the bearing block in a thread connection way, the upper shaft sleeve and the lower shaft sleeve are provided with a lubricate channel which is respectively communicated with the pipe plug and the impeller, the upper shaft sleeve and the lower shaft sleeve are articulated with an axis which is provided with a shaft shoulder, the bearing block above the shaft shoulder is communicated with the pipe plug, the bearing block is connected with a sealing box by screw thread and seals the same, the top of the sealing box is connected with a sealing cover by screw thread and a sealing filler is arranged between the sealing box and the sealing cover. The self lubricating bearing device avoids the problem of bearing lubrication maintenance and prolongs the service life up to more than 10 times, so as to reduce the cost and facilitate the users.

Description

technical field [0001] The invention relates to a maintenance-free self-lubricating bearing device for a cooling tower water turbine used for industrial water supply and drainage and central air conditioning. Background technique [0002] At present, cooling towers for industrial water supply and drainage and central air conditioning are more and more widely used. There are currently two power sources for cooling tower fans: one is to drive the fan directly by the motor or the fan is driven by the motor through a mechanical transmission reducer; the other is to use the cooling tower to drive the fan. The residual pressure of the nozzle drives a water turbine to drive the fan to rotate. The former technology belongs to the traditional technology, which is characterized by using a motor to drive the fan through mechanical transmission. The disadvantage is that driving the fan requires electricity, and the power consumption accounts for 80% of the operating cost of the cooling t...

Problems solved by technology

[0002] At present, cooling towers for industrial water supply and drainage and central air conditioning are more and more widely used. There are currently two power sources for cooling tower fans: one is to drive the fan directly by the motor or the fan is driven by the motor through a mechanical transmission reducer; the other is to use the cooling tower to drive the fan. The residual pressure of the nozzle drives a water turbine to drive the fan to rotate. The former technology belongs to the traditional technology, which is characterized by using a motor to drive the fan through mechanical transmission. The disadvantage is that driving the fan requires electricity, and the power consumption accounts for 80% of the operating cost of the cooling tower. Left and right, causing a lot of waste of power resources, and the transmission noise is large

The latter technology is to use the residual pressure of the water inlet of the cooling tower to push the simple water turbine installed at the lower part of the fan, and the water turbine drives the fan to rotate. Although this technology overcomes the power consumption caused by the former technology and the operating cost of the cooling tower High disadvantages, but the bearings used in its structure need good lubrication and maintenance, which not only causes maintenance troubles for people

Moreover, its service life is very short, the longest is only one year

This will cause unnecessary trouble and economic loss to users.

Moreover, it also causes inconvenience to the user's life.
