Description
Technical field
The present invention relates to a kind of delivery pump device.
Background technique
A lot of devices are equipped with transfer pump, are used for liquid is transported to another place from one.In central air conditioning equipment, it is provided with air compressor.The heat that produces in the compressor operation process need loose rapidly, to guarantee the normal operation of equipment.In the prior art, utilize the pump liquid that temperature is low (as water or oil) to be delivered to air compressor, utilize exchange heat, take away the heat that air compressor produces by liquid.
Of the prior artly be used to carry that heat exchange adopts with the pump of liquid is vane pump.Vane pump is because the restriction of its structural feature has not enough: 1, required precision height, processing cost height.The blade of vane pump is very high to required precision, and error must be controlled in the very little scope, otherwise can influence its work.The component of vane pump are more relatively, as four blades of employing.Required precision height and component number cause the processing cost height of vane pump more.2, resistance tocrocking is poor.Rotation produces centrifugal force and realizes conveying function vane pump by blade.Therefore, need be consistent in each sheet blade rotary course.Be stained with greasy dirt if any certain a slice blade or multi-disc blade, can cause each sheet blade angle of swing and speed difference to occur, influence is used.3, the range of flow of vane pump is little.Its range of flow is difficult to adapt to the usage requirement of big flowed fluctuation scope generally at 40～60 liters/minute.4, noise is big.Noise reaches 45 decibels.5, it is little to bear pressure.Limited by blade structure, the blade general thickness is thinner.This pressure that also causes it to bear is less, is generally about 2 kg/cm.5, temperature is poor in the blade rotary course, and is stuck easily.
Summary of the invention
The objective of the invention is provides the delivery pump device that a kind of processing cost is low, range of flow is big in order to overcome deficiency of the prior art.
For realizing above purpose, the present invention is achieved through the following technical solutions:
Delivery pump device, comprise pump case, it is characterized in that, described pump case is provided with pump case import and pump case outlet, the pump case import all communicates with the pump case inner chamber with the pump case outlet, be provided with first gear and second gear in the described pump case inner chamber rotationally, first gear and second gear are meshing with each other, and at least one fixedlys connected described first gear and second gear with the output shaft of motor.
Adopt gear to replace blade among the present invention, to the requirement reduction of machining accuracy, parts reduce, and provide cost savings.The gear rigidity is stronger, but when being stained with slight greasy dirt stable operation still, the resistance tocrocking height.Gear is stronger than the anti-pressure ability of blade, withstand voltagely can reach 25 kg/cm.Gear is in operation process, and is also easy to be stuck unlike blade.
Preferably, described first gear and the second gear outer gearing.
Preferably, first gear is identical with the second gear size.
Size is identical, can guarantee that two gear rotational speeds are identical.In rotary course, the identical gear of size can guarantee that the Volume Changes of pump case inner chamber is even, and therefore the fluid flow of output is even.
Wherein, described first gear and second gear are involute gear.
Preferably, first gear and second gear are circular gear, and the tooth of described first gear is arranged along circumference of gear direction isoperimetric; The tooth of described second gear is arranged along circumference of gear direction isoperimetric
Preferably, first gear and the second gear engagement place are divided into first chamber and second chamber with the pump case inner chamber, and the pump case import communicates with first chamber, and the pump case outlet communicates with second chamber.
Wherein, in described first chamber along gear shaft to being provided with groove, the pump case import communicates with groove.
Groove is set, but can increases the spatial volume of receiving fluids in first chamber, make liquid communication more unobstructed.
Wherein, described motor comprises motor casing, offers the outlet of motor casing import and motor casing on the motor casing, and described pump case outlet is corresponding with the motor casing entrance location.
The pump case outlet is corresponding with the motor casing entrance location, and the liquid that flows out from the pump case outlet can enter in the motor casing.
Wherein, described motor casing import is arranged on the motor casing front cover, and motor output shaft passes front cover and extends in the pump case, and pump case is fixed on the front cover.
Wherein, be provided with stator and rotor in the described motor casing, described rotor is fixedlyed connected with output shaft.
Wherein, described outlet is arranged on the rear end cover of motor casing and with transport pipe and communicates.
Wherein, described transport pipe is provided with stop valve.
The pump case outlet is worked hard in glove with mutually with the motor casing import, and liquid enters the motor casing import through the pump case outlet, behind the motor casing inner chamber, from motor casing outlet output.During machine operation, can produce some heats.Liquid flows through in motor casing, but exports behind the absorption portion heat, can prevent that motor from producing the excessive and infringement motor of heat or reducing motor properties.Delivery pump device among the present invention, in the actual using process, maximum temperature is 38 ℃, is more or less the same with ambient temperature.Can prolong the working life of motor.The present invention can be built-in use in use, and pump case, motor casing are immersed in the liquid fully, uses more convenient.
Delivery pump device among the present invention, noise is little, and processing cost is low.The gear rotational speed adjustable range is big, so its fluid flow range that can provide is big, can reach 5～300 liters/minute.The noise of its generation only is that noise is little below 10 decibels.Use environmental protection.
