Abstract
The utility model discloses an electric heating vertical self-priming pump, which comprises a pump body provided with an inner cavity. A liquid storage chamber is arranged on the lower portion of the inner cavity; the lateral wall of the pump body is in a double-layer structure; and an electric heating device is arranged in an interlayer of the lateral wall. As the lateral wall of the pump body of the vertical self-priming pump is in the double-layer structure and the electric heating device is arranged in the interlayer, when easily solidified media are conveyed or the electric heating vertical self-priming pump is operated in northern cold seasons, a power supply is switched on for preheating and heat preservation of the media by the aid of the electric heating device, the problems of pump cavity blockage and flow channel blockage caused by solidification and freezing of the media can be eliminated, and then smooth self-priming conveying for materials by the aid of the self-priming pump is realized.
Description
Technical field
The utility model relates to vertical self-sucking pump, is specifically related to the electric heating vertical self-sucking pump.
Background technique
Vertical self-sucking pump must be filled clear water or institute's fed sheet of a media in pump chamber when starting first, start the back by the high speed rotating of impeller and the gas-liquid separation device of pump itself, realized gas, the quick separation of liquid, air in the pump inlet pipeline constantly is discharged from, form vacuum in the inlet tube, thereby realized the self-priming working procedure of water pump.During termination of pumping, safety check on the exit of pump pipeline cuts out rapidly, cut off the backflow of high-order medium in the export pipeline, vacuum breaker valve on the pipeline of pump inlet is simultaneously opened synchronously, and air enters inlet ductwork, has destroyed the vacuum state in the inlet ductwork, the defective of medium back flow emptying in the pump of thoroughly having avoided causing because of siphonage, remaining in the water pump liquid storage room and pumped the medium material, realizing drainage filling liquid, the purpose of the lifelong self-priming of water pump.
Yet; carry when water pump self-suction and easily to freeze maybe need be incubated the material medium time; self-priming is shut down the back and is started in the operation process first; material can freeze in the pump chamber liquid storage room and solidify; stop up the liquid storage room space; influence the unobstructed of pump inlet runner, therefore, common vertical self-sucking pump is worked in cold season in the north and is difficult to start smoothly normal operation.
The model utility content
Technical problem to be solved in the utility model is to solve vertical self-sucking pump in northern cold season, and medium freezes and stops up the normally problem of self-priming work of pump that causes in the pump chamber liquid storage room.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopted provides a kind of electric heating vertical self-sucking pump, comprises the pump housing, the described pump housing has an inner chamber, the bottom of described inner chamber is a liquid storage room, and the sidewall of the described pump housing is a double layer construction, is provided with Electric heating appliance in the interlayer of sidewall.
In such scheme, the height of described Electric heating appliance is more than or equal to the height of liquid storage room.
In such scheme, described Electric heating appliance is provided with temperature detect switch (TDS).
In such scheme, the outer field material of the pump housing is the insulation thermal-protective material.
The pump housing sidewall of the vertical self-sucking pump that the utility model provides is a double layer construction, and Electric heating appliance is set in interlayer, like this, when the easy setting medium of conveying or when working northern cold season, plug in and medium is carried out preheating, insulation by this Electric heating appliance, can eliminate medium because of solidifying the obstruction pump chamber that freezes and cause, stop up the problem of runner, thereby realize the smooth self-priming conveying of self-priming pump material.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is made detailed explanation.
As shown in Figure 1, the utility model comprises the pump housing 1, the pump housing 1 has an inner chamber 11, the bottom of inner chamber 11 is a liquid storage room 12, the sidewall of the pump housing 1 is the double layer construction of being made up of inwall 13 and outer wall 14, and the preferred material of outer wall 14 is provided with Electric heating appliance 2 for the insulation thermal-protective material in the gap (interlayer) between inwall 13 and the outer wall 14, Electric heating appliance 2 is that one group of resistance wire outsourcing insulation is formed, and ring set is in inwall 13 outsides.Electric heating appliance 2 is connected on the power plug 3 by power line, and is provided with temperature detect switch (TDS), by temperature detect switch (TDS) heating-up temperature is automatically set in 10 ℃ of-25 ℃ of scopes.Electric heating appliance and temperature control method adopt prior art, are not described in detail in this its concrete structure.
The purpose of this utility model is by the material in the Electric heating appliance heating liquid storage room, does not solidify so that it can not freeze, and preferred version is the height of the height of Electric heating appliance 2 more than or equal to liquid storage room 12, to realize the heating to whole liquid storage room.In addition, can play the effect of insulation by the outer wall 14 made of insulation thermal-protective material, to reduce power consumption.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technological scheme, all fall within the protection domain of the present utility model.
