Abstract
The utility model relates to a machine oil pressure warning unit, comprising an oil pressure chamber, a motion mechanism, an end cover assembly, a protective sleeve and an electric appliance connecting plug sheet, wherein the oil pressure chamber adopts an enclosed chamber formed by a base, a seal rubber ring, a membrane, insulation contactors and a contact plate for preventing the leakage of machine oil, the contactors and a spring form the motion mechanism, the end cover assembly with the electric appliance connecting plug sheet is provided above the base, the protective sleeve is provided outside the end cover assembly, and the end cover assembly is provided with exhaust ports. The machine oil pressure warning unit has the advantages of simple and reasonable structure, high temperature resistance, corrosion resistance, high stability and long service life.
Description
Technical field
The utility model relates to a kind of alarm, a kind of specifically engine oil pressure alarm that can accurately transmit engine oil pressure information in the motor.
Background technique
The engine oil pressure alarm is a vitals in diesel engine and the petrol engine, when the engine oil pressure of motor is below or above outside the allowed band, just show that motor is out of order, for fear of bigger motor accident (scaling loss bearing shell) takes place, should be very important by the signal alarm and reminding person of controlling immediately.When the engine oil pressure of motor surpassed or is lower than the permitted value of regulation, instrument panel sent the red led optical signal, and driver's shutting engine down at once fixes a breakdown,, to avoid bigger motor accident.The engine oil pressure alarm is the circuit switch and the signaling lamp of connecting that are subjected to engine oil pressure control.Non air exit hole on the end cap of at present domestic engine oil pressure alarm, when the engine oil pressure alarm is worked under the condition of high temperature, the pressure of its inner chamber raises, alarm pressure value is raise, the scope that causes the alarm pressure value overshoot, the engine oil pressure alarm was lost efficacy, cause motor generation serious accident.
Summary of the invention
The purpose of this utility model is that a kind of simple and reasonable, high temperature resistant, corrosion-resistant, good stability will be provided, the engine oil pressure alarm of long service life.
The purpose of this utility model is achieved in that this alarm comprises oil pressure chamber, motion, end cap combination, protecting jacket, has exhaust port in the described end cap combination,, protecting jacket is arranged on the outside of end cap combination.
Described oil pressure chamber is a seal chamber that prevents lubricating oil leakage that is made of base, O-ring seal, diaphragm, insulation contact and contact disc, and contact and spring constitute a motion, have end cap combination that electrical equipment connects inserted sheet be arranged on base above.
Described O-ring seal, diaphragm, insulation contact and contact disc are successively set in the inner chamber on the base from the bottom to top, and contact and spring are successively set in the inner chamber of top, end cap combination of insulation contact.
Described diaphragm is the sensing element of switch, adopts resistant to elevated temperatures material, makes it have characteristics high temperature resistant, corrosion-resistant, good stability.
The utility model has kept the air pressure of engine oil pressure alarm internal cavity and air barometric pressure to keep balance owing to increasing exhaust port in the end cap combination, and alarm is worked under the condition of high temperature, and alarming value does not change; Owing to protecting jacket is set, had water-proof function simultaneously in the outside of end cap combination.No matter the temperature of this engine oil pressure alarm motor is high and low, the engine oil pressure alarm all has alarm pressure value and does not change, and has the stable characteristics of indicating value.

Embodiment
Shown in accompanying drawing: this alarm comprises oil pressure chamber, motion, has end cap combination 10, protecting jacket 7 that electrical equipment connects inserted sheet 9; described oil pressure chamber is a seal chamber that prevents lubricating oil leakage that is made of base 1, O-ring seal 2, diaphragm 3, insulation contact 4 and contact disc 5; contact 6 and spring 8 constitute a motion; have end cap combination 10 that electrical equipment connects inserted sheet 9 be arranged on base 1 above, protecting jacket 7 is arranged on the outside of end cap combination 10.
Described O-ring seal 2, diaphragm 3, insulation contact 4 and contact disc 5 are successively set in the inner chamber on the base 1 from the bottom to top, and contact 6 and spring 8 are successively set in the inner chamber of top, end cap combination 10 of insulation contact 4.
Have exhaust port 11 in the described end cap combination 10.
Described diaphragm 3 is sensing elements of switch, adopts resistant to elevated temperatures material, makes it have characteristics high temperature resistant, corrosion-resistant, good stability.
During work, machine oil enters from hydraulic fluid port 12, and when oil pressure raise, oil pressure made diaphragm 3 and insulation contact 4 move upward together, and contact 6 and contact disc 5 are broken away from, and circuit disconnects, and the instrument panel signaling lamp that at this moment is connected inserted sheet 9 connections with electrical equipment goes out; When not having oil pressure, signaling lamp bright (warning).
