Abstract
The utility model discloses an oil pump which comprises a pump shell, a pump shaft, an inner tube arranged in the pump shell and an impeller arranged on the pump shaft. The pump shaft is fixedly connected with the impeller through an elastic cylindrical pin or a key. The pump shaft and the impeller are integrated together. The thickness of the upper portion of the inner tube is larger than that of the lower portion of the inner tube. The two sides of the inner tube are respectively provided with an oil inlet and an oil outlet which are respectively corresponding to an oil inlet hole and an oil outlet hole of the pump shell. The oil pump has the advantages of being easy to carry, place and maintain, having simple structure, easy operation, long working time, high efficiency, long service life, better automatic suction capability, low production cost, simple processing and the like.
Description
Technical field
The utility model relates to a kind of oil pump.
Background technique
Oil pump should have very extensive in life and in the engineering construction, oil is extracted into another container from a container, in the case, with the effect of carrying on a shoulder pole oil pumping, in engineering construction, voltage is safety voltage, and present oil pump is all smaller, is difficult to satisfy the needs of big flow and lift, and in use, easily heating, flow is generally less, and precision height, difficulty of processing are big.So urgency is waited to research and develop a kind of simple in structure, easy to process, and lift and all bigger oil pump of flow, satisfy the many oil pumping work in the life.
The model utility content
The purpose of this utility model provides a kind of oil pump, be cheaper than and carry, lay, have simple in structure, easy to operate, transport the time long, safeguard easily, high, the long service life of efficient, have stronger advantages such as suction capacity, and cost of production is low, and processing is simple.
The technical solution adopted in the utility model is as follows:
A kind of oil pump, include pump housing shell, pump shaft, be provided with the inner tube of a tyre in the pump housing shell, impeller is installed on the pump shaft, be fixed as one by elastic cylindrical pin or key connecting between described pump shaft and the impeller, described inner tube of a tyre top is greater than the thickness of bottom, and the both sides of the inner tube of a tyre have oil inlet hole, oil outlet respectively, and oil inlet hole, oil outlet correspond respectively to filler opening, the oil outlet of pump housing shell.
The shape ovalize of described oil inlet hole, oil outlet.
After the utility model energising, the rotation of driven by motor pump shaft, pump shaft also can be connected by key by elastic cylindrical pin is fixing with impeller, thereby impeller is being followed at interior tyre cavity and is being rotated, the cavity shape of the inner tube of a tyre is irregular, because inner tube of a tyre inner chamber switch makes impeller in rotary course, inner tube of a tyre top is greater than the thickness of bottom, below impeller blade under when forwarding to, leftward space is changed from small to big, because the close filling of whole inner chamber, so produce a kind of suction, oil be drawn onto in the chamber; Simultaneously rightward space from large to small, the oil in the chamber is forced out inner tube of a tyre inner chamber under pressure, thereby Yi Bian oil from pressing to another side, finish oil pumping work.
Compared with the prior art, the beneficial effects of the utility model are as follows:
Pump beautiful shape of the present utility model, be cheaper than and carry, lay, have simple in structure, easy to operate, transport the time long, safeguard easily, high, the long service life of efficient, have stronger advantages such as suction capacity, and cost of production is low, and processing is simple, and example is in batch process, remedied the blank of domestic impeller oil pump, made our company more competitive on market.
