Abstract

The utility model relates to an automatic hydraulic oil-selling unit, mainly comprising an oil-selling oil quantity controller, an oil tank, an oil level controller, a hydraulic control system, an electric apparatus control system and an electromagnet counter. The unit can select metrology of selling oil in a range of 50g-5000 g. The utility model has the advantages of high speed and little error. 8 seconds is needed to give 1 kg oil out. Because a hand-held oil-selling unit mechanism is reserved, oil-selling is not effected when power is off or a circuit is broken down.

Description

Automatic hydraulic oil-selling unit

The automatic oil-vending device of a kind of fluid pressure type can automatic guidance metering or the manual oil-vending device of controlling metering when being used for retail edible vegetable oil.

General manual oil-vending device mainly constitutes by connecing oil nozzle, oil outlet pipe, metering oil cylinder, metering piston, delivery valve etc., labour intensity is big during use, and existing automatic oil-vending device is made up of recorder jar, magnet steel floating drum, turnover fluid electromagnetic valve, dry-reed tube locating support, command control panel, stock's container.This oil-vending device along with the density of oil changes and produces metering error, makes it not meet the measurement standard requirement in use when the variety renovation of oil or ambient temperature change, and can not use when circuit is out of order.

The purpose of this invention is to provide a kind of measurement standard that all meets can in any ambient temperature, sell oil to various edible vegetable oils the time, can automatic guidance, the manual oil-vending device of control.
