Abstract
The invention relates to a cartridge type controllable electric-tracing anti-freezing pump shaft seal device which can heat a self-sucking pump shaft seal with a prepositioned device. In the pump shaft seal device, the back side of a pump shaft seal end cover is provided with heater. The invention can thoroughly solve the problem that the self-sucking pump with a prepositioned device can not be started and operated as a result of the freezing of the shaft seal under the external cold conditions. Besides, the invention has the advantages of simple structure, convenient installation, low price and obvious use effect.
Description
Technical field
The present invention relates to a kind of anti-icer of pump, relate in particular to a kind of controlled electrical tracing deicing pump of unit loading type gland seal device that seals heating for the self-priming pump shaft of wearing front device, can solve by application of the present invention wear front device self-priming pump under the condition of outdoor cold, freeze the technical barrier that can't start because of axle envelope place.
Background technique
Pump is widely used in factory, mine, urban water supply and sewerage, also can be used for power station, large hydraulic engineering, farmland discharging-irrigating etc.
At present, when under the condition of pump in outdoor cold during installation and operation, even the water emptying in the stand by pump pump chamber, when needs start, also because of sealing the remaining liquid film freezing in sealing surface place, axle can't start through regular meeting.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, the controlled electrical tracing deicing pump of a kind of unit loading type gland seal device is provided, solved wear front device in the prior art self-priming pump under the condition of outdoor cold, freeze the technical barrier that can't start because of axle envelope place.
Technological scheme of the present invention is as follows:
The back side of pump shaft end-blocking lid is provided with heater.
Described heater is fixed on the pump shaft end-blocking by hold-down ring and hold-down bolt and covers.
Described heater is a ring.
Described electric heater is provided with the temperature controller of control heating-up temperature.
Advantageous effect of the present invention is as follows:
By the present invention, under the condition of outdoor cold, can thoroughly solve the self-priming pump of wearing front device freezes to start operation because of axle envelope place a difficult problem; And, simple in structure, easy for installation, low price, using effect is remarkable.
