Description
Technical Field
The utility model relates to a pump body technical field especially relates to a diaphragm oil pump.
Background
The miniature diaphragm pump is an instrument for conveying fluid media, and is provided with a suction nozzle and an exhaust nozzle which are arranged in one inlet and one outlet respectively, and a diaphragm in the pump is made to do reciprocating motion through a mechanical device, so that negative pressure and positive pressure are formed to suck fluid.
At present, the miniature diaphragm pump on the market can only pump water or general non-corrosive low-viscosity liquid, however, lubricating oil or engine oil used in industry has certain viscosity, some also have corrosiveness, and the common diaphragm pump can not meet the special oil condition of machine equipment.
To meet the performance requirements of this market, new diaphragm oil pumps are therefore required to be designed.
Disclosure of Invention
The utility model aims at the technical problem who exists, provide a simple structure, can not only satisfy the demand of ordinary liquid extraction, can also satisfy the extraction requirement of viscidity and corrosive liquids simultaneously, be applicable to the industrial diaphragm oil pump.
In order to achieve the above purpose, the utility model discloses practical technical scheme does:
a diaphragm oil pump comprises a motor, a cylinder body, an upper cover and a lower cover, wherein a cavity for movement of a diaphragm is arranged in the cylinder body; a partition plate is arranged above the rubber diaphragm, a piston is arranged above the partition plate, and the rubber diaphragm is connected with the piston through a pull rod and drives the piston to move; the piston top be provided with the valve plate, be provided with inlet port and oil outlet on the valve plate, install oil feed umbrella butyl and the umbrella butyl that produces oil respectively in two holes and be used for controlling to open.
In the scheme, the oil inlet umbrella T and the oil outlet umbrella T are arranged in opposite directions, and when the umbrella T works, one umbrella T is opened and the other umbrella T is closed.
In the scheme, the transmission mechanism is a cam transmission mechanism, one end of the connecting rod is connected to the edge of the cam, and the other end of the connecting rod pulls the rubber diaphragm to reciprocate.
In the scheme, the surface of the piston is made of corrosion-resistant materials, and the bottom surface of the piston is connected with the pull rod through flexible materials.
The utility model discloses a principle is to keep apart rubber diaphragm and fluid, adopts corrosion resistance's piston to replace rubber diaphragm to move, and rubber diaphragm then seals and drives the piston in other cavity and move, and then has played the effect of protection rubber diaphragm.
The beneficial effects of the utility model reside in that:
the utility model discloses simple structure adopts isolation measure to protect the rubber diaphragm, can not only satisfy the demand of ordinary liquid extraction, can also satisfy the extraction requirement of viscidity and corrosive liquids simultaneously, is applicable to industrial production.
