Abstract
The utility model discloses a vertical self sucking pump with the preheating function. The vertical self sucking pump comprises a pump body, wherein the pump body is provided with an inner cavity; a liquid storage chamber is formed at the lower part of the inner cavity; a steam coil is arranged in the liquid storage chamber; two openings are arranged on the wall of the liquid storage chamber; and two ends of the steam coil are respectively fixed at the openings. The steam coil is arranged in the liquid storage chamber of the vertical self sucking pump; and when the vertical self sucking pump is operated in the North in cold seasons, steam or hot water is fed into the steam coil for preheating, so that the blocking of the vertical self sucking pump caused by solidified and frozen medium can be eliminated, and smooth self sucking and material conveying can further be realized.
Description
Technical field
The utility model relates to vertical self-sucking pump, is specifically related to the vertical self-sucking pump with rre-heated.
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 vertical self-sucking pump with rre-heated, comprise the pump housing, the described pump housing has an inner chamber, the bottom of described inner chamber is a liquid storage room, be provided with a steam pipe coil in the described liquid storage room, the locular wall of liquid storage room is provided with two openings, and the two ends of described steam pipe coil are separately fixed on the described opening.
In such scheme, be fixed with pipe joint on the described opening.
In such scheme, it is poroid that the axis hole of described pipe joint is the little ladder in inner big outer end, and the step surface of the end of described steam pipe coil and the axis hole of pipe joint offsets.
In such scheme, the outer end of the axis hole of described pipe joint is outside bell mouth shape of big end opening or taper hole shape.
In such scheme, the internal diameter of described steam pipe coil is greater than the internal diameter of the axis hole of pipe joint.
In such scheme, the internal diameter of described steam pipe coil is 10-30mm.
In such scheme, described steam pipe coil is copper pipe or Stainless Steel Tube.
The utility model, in the liquid storage room of vertical self-sucking pump, be provided with steam pipe coil, when work cold season in this vertical self-sucking pump north, feeding steam or hot water carry out preheating in steam pipe coil, can eliminate medium because of solidifying the obstruction of freezing and to cause, thereby realize that self-priming pump carries the smooth self-priming of material.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the pipe joint structure schematic representation.
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 locular wall of liquid storage room 12 is provided with two openings, is respectively equipped with pipe joint 3 in the opening, and a kind of concrete structure of pipe joint 3 as shown in Figure 2, it is poroid that the axis hole 31 of pipe joint 3 is the little ladder in inner big outer end, and the outer end 32 of axis hole 31 is outside bell mouth shape of big end opening or taper hole shape.Pipe joint 3 is inserted into respectively in the opening on the liquid storage room locular wall, and fixes with the outer wall of liquid storage room 12.Be provided with a steam pipe coil 2 in the liquid storage room 12, the internal diameter of steam pipe coil 2 is greater than the internal diameter of the axis hole 31 of pipe joint, and the two ends of steam pipe coil 2 offset with the step surface 33 of the axis hole of pipe joint 3 respectively.
In the utility model, steam pipe coil 2 can be selected copper pipe or Stainless Steel Tube, and internal diameter is 10-30mm.
The utility model is provided with steam pipe coil 2 in the liquid storage room 12 of vertical self-sucking pump, when working northern cold season, in steam pipe coil 2, feed steam or hot water and can carry out preheating liquid medium remaining in the liquid storage room 12, eliminate medium because of solidifying the obstruction of freezing and causing, thereby realize the smooth self-priming conveying of self-priming pump material.
In addition, the internal diameter of steam pipe coil 2 is greater than the internal diameter of the axis hole 31 of pipe joint, and the outer end 32 of axis hole 31 is outside bell mouth shape of big end opening or taper hole shape, can improve to enter steam pipe coil 2 steam or flow rate of liquid, prevents that impurity is deposited on the inwall of steam pipe coil 2.
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.
