An oil pump steering indicator

Abstract

The invention provides an oil pump steering indicator, which belongs to the technical field of oil pumps. It solves the problem that the running direction of the existing oil pump cannot be identified. The oil pump includes a casing and a rotating shaft arranged in the casing. The end of the rotating shaft is fixedly connected with the first gear, and a mounting hole is opened in the casing. Steering shaft, the inner end of the steering shaft is fixedly connected with the second gear, pushing the steering shaft can make the first gear mesh with the second gear, the outer end of the steering shaft is fixedly connected with an indicator, and the middle of the steering shaft is fixedly connected with a convex The locating piece is provided, the steering shaft is covered with a return spring, and the two ends of the return spring act on the indicator and the casing respectively, and the first gear and the second gear can be separated and positioned under the action of the spring force of the return spring. The part rests against the housing, and the steering shaft can be positioned axially in the mounting hole. This oil pump direction indicator makes the direction of operation of the oil pump externally visible.

Description

technical field [0001] The invention belongs to the technical field of oil pumps and relates to an oil pump steering indicator. Background technique [0002] The oil pump is a light and compact pump, which can be divided into three categories: inline type, distribution type and single type. The oil pump needs a power source to run, and the camshaft at its lower part is driven by the crankshaft gear of the engine. [0003] Existing oil pumps, for example, Chinese patent literature discloses a transformer oil pump cooling system [application number: 201810553729.X; application publication number: CN108757579A], which includes a housing, an inlet and an outlet located on the housing, and an inlet and an outlet located on the housing. The impeller inside the body, and the motor structure inside the housing, also includes a detachable impurity removal structure at the bottom of the housing; wherein, the motor shaft of the motor structure is set perpendicular to the channel betwe...

AI Technical Summary

Problems solved by technology

When the oil pump is installed, there is often a problem of reverse steering due to mistakes and wiring errors. The reverse operation of the oil pump will cause the flow rate and head of the oil pump to decrease, and the current will increase. The final result will reduce the cooling effect of the transformer, and reverse operation will also cause The life of the oil pump itself is reduced

The outer casing of the oil pump is made of metal material, and the oil inlet and outlet are connected to the connecting pipe of the transformer. After the oil pump is installed, the entire rotating part is inside the oil pump, and people cannot directly observe it from the outside, so they cannot judge Is the operation of the oil pump reversed?
