Abstract
The utility model provides a household central heating pump, and the pump body is an upright tee joint. The pump body is connected with a motor through a shockproof rubber pad to decrease the noise. A thrust bearing cone-shaped concave hole towards upward and the dirt is unease to deposit. A main shaft is sheathed with a ferrule rubbing with a plastic bearing to prevent from being jammed not to rotate for corrosion. When the main shaft is provided with a screw feeder driven by the motor to rotate, the hot water flows quickly. When the motor stops, the hot air and the hot water still can carry out the natural convection circulation along a spiral gap of the screw feeder. The main shaft of the household central heating pump is provided with a packing seal, and the household central heating pump can not have the water leakage phenomenon if the water level doesn't exceed the upper opening.
Description
The utility model relates to a kind of household central heating water pump of improvement, especially for exclusive special-purpose small-sized household hot-water heating heating installation water pump.
Household small-size hot-water heating heating installation is widely used in the Chinese north, but this heating installation utilizes hot water free convection circulation, and flow velocity is low, and heat-transfer effect is bad, and radiator effect more a little further is poorer.
For addressing this problem, common way is that a water circulating pump is installed on caliduct, to accelerate flow rate of hot water.Commercially available household central heating circulating pump has centrifugal water pump at present, when switching off the pump, need establish bypass pipe in addition by the free convection of heating installation hot water, troublesome poeration, and use for a long time, leak at main shaft and sealing place, need to change sealing, motor and water pump be rigid, and to be connected the noise that gets into smooth big.In addition, obtained Patent right 89200056 " household central heating water pumps ", found also that through the practice utilization weak point is arranged,, establish the support fixed electrical machinery in addition, made troubles to the user as not having fixture between the motor and the pump housing; Moreover because of main shaft is made of iron, when through spring, summer, autumn, the time spent did not just get rusty, what have is serious because of corrosion, block and do not change, the main shaft of corrosion directly and the plastic bearing friction, the very fast plastic bearing that just can wear and tear.
The purpose of this utility model is that a kind of improved household central heating pump will be provided, and makes it easy for installation, and simple to operate, noise is little, and is wear-resistant, and the main shaft corrosion still can be turned round.Long-term operation is guaranteed can not leak, and still can rely on hot water free convection to continue circulation after the power failure.
Task of the present utility model is that following mode is finished: the pump housing is connected with rubber blanket is shockproof with motor, and is easy for installation, reduces noise.The taper shrinkage pool of thrust bearing is difficult for the deposition dirt, thereby increases the service life down.With lasso of collar bush and plastic bearing friction, can not block and not change and the plastic bearing that weares and teares because of the main shaft corrosion.The pump housing is vertical threeway, is installed in the most significant end of caliduct, and the suitable for reading of pump need not seal, as long as it is suitable for reading to make the water level of expansion tank be no more than the pump housing, just leak never.Screw feeder is installed on the main shaft, is rotated under the driving of motor, the hot water in the pipeline just flows rapidly.When disable motor, hot water still can continue circulation lentamente along the free convection of screw feeder gap between screw.
Below in conjunction with accompanying drawing the utility model is done detailed description:
Fig. 1 is the longitudinal sectional view of household central heating pump.
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is the scheme of installation of household central heating pump.
With reference to Fig. 1, a vertical threeway pump housing (1) mesopore and following Kong Jun have 3/4 cun screw thread, there is flange disc (2) outer in last hole, and 3 screw holes are arranged on the flange disc (2), and three screws (3) link together by three rubber blankets (4) and motor (5) respectively.Jaw and toothed coupling (6) is housed on the motor shaft, and identical jaw and toothed coupling (6) also is equipped with in main shaft (14) upper end, so as to transferring power.Main shaft top has axle sleeve (7) to rub mutually for spherical bearing (8) with the outer.Screw feeder (9) is equipped with in the main shaft bottom, the downward last thrust bearing (10) of 90 degree taper shrinkage pools is equipped with in the main shaft lower end, it with have 60 degree-70 degree awl points following thrust bearing (11) up opposed, following thrust bearing (11) supports with three radiation tendons and links to each other with annulus.The no screw thread of pump body top cover (12), it is to borrow the packing ring (13) of three rubber blankets to compress.
With reference to Fig. 3 household central heating water pump scheme of installation, (1) is boiler among the figure, and (2) are water tanks, and (3) are the household central heating pumps, and (4) are fin.
