Description

A kind of lobed rotor pump
Technical field
The utility model relates to rotor pump, particularly relates to a kind of lobed rotor pump.
Background technique
Current rotor pump utilizes the periodicity of multiple fixed volume convey unit to be converted to reach the object of carrying fluid.But current rotor pump structure is complicated, and use inconvenience, whole system balances not, easily occur that leaking oil condition occurs.
Model utility content
Complicated in order to solve prior art rotor pump structure, use inconvenience, whole system balances not, easily occur that the problem that leakage of oil situation occurs, the utility model provide a kind of structure simple, easy to use, whole valve body can be kept to balance, oil-proof, free of contamination lobed rotor pump.
In order to solve the problem, technical solution adopted in the utility model is:
A kind of lobed rotor pump, comprise the pump housing, it is characterized in that: also comprise cam follower, blade and live axle, offer in the middle part of the pump housing and be equipped with through hole, described cam follower is arranged in through hole, described live axle is through cam follower and band can drive cam follower to rotate, blade is respectively arranged with in cam follower both sides, the sealed volume that cam follower and the pump housing surround is divided into two laminated oil zones and Liang Ge oil suction district by described blade, the pump housing is provided with inlet port and force feed mouth, and described inlet port is connected with sealed volume respectively by pipeline with force feed mouth.
Aforesaid a kind of lobed rotor pump, is characterized in that: described blade can stretch.
Aforesaid a kind of lobed rotor pump, is characterized in that: described inlet port and force feed mouth are symmetrical arranged.
Aforesaid a kind of lobed rotor pump, is characterized in that: the described pump housing adopts stainless steel material to make.
Aforesaid a kind of lobed rotor pump, is characterized in that: described blade adopts wolfram steel material to make.
Aforesaid a kind of lobed rotor pump, is characterized in that: described force feed mouth volume is greater than inlet port volume.
The beneficial effect that the utility model reaches: the utility model lobed rotor pump, blade is respectively arranged with in cam follower both sides, the sealed volume that cam follower and the pump housing surround is divided into two laminated oil zones and Liang Ge oil suction district by described blade, the pump housing is provided with inlet port and force feed mouth, and described inlet port is connected with sealed volume respectively by pipeline with force feed mouth.The utility model utilizes blade to control the size in laminated oil zone and oil suction district, along with the revolution of cam follower, the sealed volume of laminated oil zone diminishes gradually, by laminated oil zone to system force feed, the sealed volume in oil suction district becomes large gradually, by inlet port to fuel tank oil suction, convenient to use, whole system balances more.
Accompanying drawing explanation
Fig. 1 is the utility model lobed rotor pump structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, a kind of lobed rotor pump, comprise the pump housing 1, cam follower 2, live axle 3 and blade 4, offer in the middle part of the pump housing 1 and be equipped with through hole, described cam follower 2 is arranged in through hole, described live axle 3 is through cam follower 2 and band can drive cam follower 2 to rotate, blade 4 is respectively arranged with in cam follower 2 both sides, the sealed volume that cam follower 2 and the pump housing 1 surround is divided into two laminated oil zones 5 and Liang Ge oil suction district 6 by described blade 4, the pump housing 1 is provided with inlet port 7 and force feed mouth 8, described inlet port 7 is connected with sealed volume respectively by pipeline with force feed mouth 8.Described blade 4 can stretch.Described inlet port 7 and force feed mouth 8 are symmetrical arranged.The described pump housing 1 adopts stainless steel material to make.Described blade 4 adopts wolfram steel material to make.Described force feed mouth 7 volume is greater than inlet port 8 volume.
In sum, the utility model lobed rotor pump, blade 4 is respectively arranged with in cam follower 2 both sides, the sealed volume that cam follower 2 and the pump housing 1 surround is divided into two laminated oil zones 5 and Liang Ge oil suction district 6 by described blade, the pump housing 1 is provided with inlet port 7 and force feed mouth 8, and described inlet port 7 is connected with sealed volume respectively by pipeline with force feed mouth 8.The utility model utilizes blade 4 to control the size in laminated oil zone 5 and oil suction district 6, along with the revolution of cam follower 2, the sealed volume of laminated oil zone 5 diminishes gradually, by laminated oil zone 5 to system force feed, the sealed volume in oil suction district 6 becomes large gradually, by inlet port 7 to fuel tank oil suction, convenient to use, whole system balances more.
More than show and describe basic principle of the present utility model, major character and advantage.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
