Description
Technical field
The utility model relates to Submerged Motor Pumps, especially a kind of special-purpose Submerged Motor Pumps of fountain that adopts mechanical seal structure.
Background technique
At present, the special-purpose Submerged Motor Pumps of existing traditional fountain mainly contains two kinds: a kind of is oil-filled type Submerged Motor Pumps, and another kind is a water-filling type Submerged Motor Pumps.The motor of oil-filled type Submerged Motor Pumps adopts the integral sealing structure, in case sealed member lost efficacy, motor just burns easily because of water inlet, thereby causes entire pump to be damaged.Water-filling type Submerged Motor Pumps adopts partially sealed, and sealing generally adopts oil sealing sealing mainly at bearing part, because the working life of oil sealing sealing is not long, oil sealing damages after using a period of time easily, causes having impurity to enter in the bearing, damage bearing, thereby make Submerged Motor Pumps produce fault.Fountain often starts frequently with pump, and its working environment that sinks under the water makes replacing, difficult in maintenance, so be badly in need of a kind of long service life, submersible pump that rate of fault is low.
The model utility content
At the deficiency of above existing fountain with Submerged Motor Pumps, the purpose of this utility model provides a kind of novel structure, good sealing effect, the special-purpose submersible pump of the fountain of long service life.
The purpose of this utility model is achieved by the following technical solution:
The special-purpose submersible pump of fountain, mainly form by water pump and motor, water pump comprises the pump housing, main shaft and impeller, the top and bottom of the pump housing are respectively equipped with water pipe adapter and water inlet joint, motor comprises support, stator and rotor, main shaft is connected with rotor and fixes, the pump housing is connected with support by the water inlet joint, main shaft is connected with support with the water inlet joint respectively by bearing, impeller is installed in the upper end of main shaft, be provided with mechanism's seal arrangement between described main shaft and the water inlet joint, the external stability parts of mechanism's seal arrangement are connected with the water inlet joint and fix, and its internal activities parts are connected with main shaft and fix.
As optimal technical scheme of the present utility model, the coil of described motor adopts waterproof rule structure.
As optimal technical scheme of the present utility model, be filled with fluid in the described motor, have good lubricating to guarantee bearing, and motor is fully cooled off.
As optimal technical scheme of the present utility model, between described water inlet joint and the support O RunddichtringO is installed.
As optimal technical scheme of the present utility model, the lower end of described support is provided with lower cover, and the lower cover center is provided with bearing support, and the lower end of described main shaft is connected with lower cover by bearing, and lower cover is connected with support by bolt and fixes, and the jointing place adopts seal approach.
As optimal technical scheme of the present utility model, a side of described support is provided with terminal box, is provided with wire board in the terminal box, and cable is connected with the motor coil circuit by wire board.
The beneficial effects of the utility model are: with respect to prior art, the advantage of the utility model set water-filling type Submerged Motor Pumps and oil-filled type Submerged Motor Pumps, the motor of pump partly adopts the waterproof rule structure of water-filling type submersible pump, and main shaft adopts mechanical seal to do shaft sealing, and motor internal is oil-filled.The utility model has the advantage of water-filling type and oil-filled type Submerged Motor Pumps simultaneously, and the bearing lubrication of electric pump is good, longer service life; Even motor internal has a small amount of water inlet, motor stator can not burn out yet, and has solved the heat dissipation problem of motor simultaneously, thereby makes the longer service life of Submerged Motor Pumps, is specially adapted to fountain and uses.
