Abstract
The utility model discloses a gear pump with a novel structure-a two-way pumping machine. The pumping machine alters the large working solution chamber of the existing gear pump and the direct communication type structure of the liquid absorption part, liquid discharge part, and the solution cavities in the pump body. The outside of the pump body (2) is additionally provided with a liquid absorption and storage cavity with a large caliber (28) and a liquid discharge and storage cavity (32). The solution cavities (29) (30) in the pump body are reduced. The liquid absorption nozzle (35) and liquid discharge nozzle (31) of the pumping machine are arranged on the pump body to communicate with the solution cavity with the small volume after the buffering of the liquid storage cavity with the large caliber. Therefore, the suction lift and the delivery lift of the pump are increased, and the function of pumping and spraying are achieved. The pumping machine which has multiple functions can pump and spray the liquid, the volume is small, the weight is light, and the use is flexible and convenient.
Description
The utility model has related to gear pump.A kind of specifically adopt gear pump structure can two-way imbibition, the spray machine of taking out of discharge opeing.This two-way spray machine of taking out can be used for drawing water, pumping, and also can be used for water spray, pesticide, whitewashing liquid etc.
Existing gear pump all has solution cavity on the pump housing.Make the imbibition chamber and the exhaust chamber of the pump housing be rendered as big cavity volume, and the imbibition chamber is greater than exhaust chamber.Be provided with compensating groove in pump housing domestic demand, sealing, blank compensation apparatus.Liquid entering hole part and liquid port partly are single caliber.The gear pump of this structure is applicable to does oil hydraulic pump usefulness in hydraulic machinery, and is unsuitable for doing liquid sorption pump or Liquid spraying pump.
The purpose of this utility model is to release a kind of gear pump of novel structure---the two-way spray machine of taking out.Thisly take out the characteristics such as solid, durable that the spray machine had both kept existing gear pump, have vane pump again, the partial function of reciprocating pump is done drawing liquid or Liquid spraying pump and is used.Thereby expanded the function of gear pump, enlarged the using scope of gear pump.
Task of the present utility model is to set up supercharging, buffer cavity by the volume that dwindles the solution cavity in the gear pump pump housing with in pump housing outside---the way of liquid storage cylinder realizes.
Specific practice is, no longer offers imbibition chamber and exhaust chamber on the pump housing of gear pump, but directly utilizes the tooth surface of pair of meshing of working gear and space that the gear cavity wall is surrounded as imbibition chamber and exhaust chamber.Respectively be connected to the imbibition liquid storage cylinder and the discharge opeing liquid storage cylinder in footpath at a gulp in the both sides external of the pump housing, one end of liquid storage cylinder is communicated with the imbibition chamber and the exhaust chamber of the pump housing respectively by imbibing hole and the outage that is positioned on the pump housing, and the other end of liquid storage cylinder is connected to a small-bore suction separately, discharge opeing is chewed.Imbibition chews that to chew with discharge opeing be separately through receiving on the pump housing behind the bigbore liquid storage cylinder in the utility model, the bore that imbibition is chewed with discharge opeing is chewed equates, the volume of imbibition liquid storage cylinder and discharge opeing liquid storage cylinder is equal, and greater than imbibition chamber and exhaust chamber with equal volume.The bore that chew with imbibition in the aperture of imbibing hole, outage, discharge opeing is chewed is identical.
Since pump housing content cavity reduce with the pump housing outside the setting of liquid storage cylinder, reduced leakage, improved volumetric efficiency and degree of vacuum, make pump increase certain suction journey and lift.The setting of liquid storage cylinder has also reduced the direct impact of liquid to pump gear, guaranteed flow continuously and the stablizing of pump work.
The utility model includes the body part and advances, the discharge opeing part.The body part is made up of parts such as housing, end cap, bearing, main shaft, driving gear, working gear, imbibition chamber, exhaust chamber, Sealing and rocking bars; The outside that advance, discharge opeing partly is positioned at body includes suction, discharge opeing is chewed and suction, discharge opeing liquid storage cylinder, advances, discharge opeing partly is to link together by the imbibing hole that is positioned at the housing both sides, outage and body.
During work, be rotatably connected on the rocking bar on the driving gear main shaft, driving gear rotates and drives the working gear rotation work.Liquid is chewed by imbibition and is constantly entered the imbibition liquid storage cylinder, enters the imbibition chamber in the body after the buffering of liquid storage cylinder and pressure adjustment.By working gear liquid is taken to exhaust chamber, after the pressure adjustment of discharge opeing liquid storage cylinder, chew discharge again by discharge opeing.Finish the suction function of liquid.Change the size of velocity ratio and working gear, can change the flow of taking out the spray machine.Therefore, the utility model can be developed into the series product that can take out the spray different flow.
The power of taking out the spray machine can be manually, the poultry band, also can be electronic, take out the spray machine and can use, materials such as available metal, nylon, resin are made.
The utility model because adopted the little cavity volume pump body structure of symmetry and in the pump housing outer installment liquid storage cylinder, increased the suction journey when making the gear pump imbibition, increased lift during discharge opeing again, and can two-wayly use.Expand the gear pump function, enlarged the using scope of gear pump.
