Abstract
A closed liquid level transmitter of an air compressor comprises a resistor cavity and a floater cavity, wherein the resistor cavity and the floater cavity are connected through a connector. A floater is placed in the floater cavity, and a connection rod is fixed to the top end of the floater, penetrates out of the connector and is connected with a sliding assembly in the resistor cavity. A resistor membrane is installed in the resistor cavity. The closed liquid level transmitter has the advantages that due to linear resistance value output design, the step of observing the liquid level manually is eliminated, and linear output of the liquid level height is achieved; due to closed internal installation design, the closing completeness of the air compressor is improved, and the air compressor can provide stable pressure and air flow.
Description
Technical field
The utility model relates to level measuring field, particularly a kind of fluid level transmitter.
Background technique
In air compressor, the measurement great majority of liquid level adopt window type observation method, judge the height of air compressor inside liquid level, and then judge the oil reserve in air compressor.There is following shortcoming in this observation type method of measurement: liquid level vibrations are severe, and form liquid level shows that fluctuation is violent; Compressor internal environment magnetic field is more complicated, and the interference between magnetic field is comparatively serious, causes magnetic strength element not use; Opening type design, causes air compressor inner withstand voltage lower.
Summary of the invention
The purpose of this utility model is in order to address the above problem, and has designed a kind of closed air compressor fluid level transmitter.Specific design scheme is:
A kind of closed air compressor fluid level transmitter, comprise resistance chamber, float cavity, between described resistance chamber, float cavity, connect by connecting body, in described float cavity, be placed with float, the top of described float is fixed with connecting rod, described connecting rod runs through described connecting body and is connected with the sliding assembly in described resistance chamber, and described resistance is also provided with resistance diaphragm in chamber.
Described resistance diaphragm comprises substrate, cathodic coating, anode film, described substrate is secured by bolts on the inwall in described resistance chamber, described cathodic coating, anode film are all attached on described substrate, and described sliding assembly is that the rear end of Structural Hardware and described sliding assembly contacts with described cathodic coating, anode film.
Described connecting rod is column structure, and the top of described connecting rod is provided with three spring sheets.
The bottom of described float cavity is provided with chamber lid, and lid middle part, described chamber is provided with blasthole.
The closed air compressor fluid level transmitter obtaining by technique scheme of the present utility model, its beneficial effect is:
Linear resistance output design, has reduced manual observation liquid level link, has realized the linearity output of liquid level.
The inner mounting design of sealed mode, has improved the airtight integrity of air compressor, guarantees that air compressor provides stable pressure and air mass flow.
