Abstract
The utility model relates to an oil temperature and level monitoring device applied in a entry driving machine, which is composed of a programmable controller, a data line, a liquid crystal display, an oil return inlet, a hydraulic tank, an oil suction port, an oil level sensor, an oil temperature sensor and a shielded cable. The programmable controller is connected with the liquid crystal display by the data line. The oil level sensor and the oil temperature sensor are arranged inside the hydraulic tank respectively. The upper ends of the oil level sensor and the oil temperature sensor are connected with the programmable controller by the shielded cable. The hydraulic tank is provided with the oil suction port at the bottom, and the oil return inlet at the top. The device has the simple structure, and can carry out the real-time monitoring on the condition of the oil temperature and the oil level, which are then displayed directly on the liquid crystal display. In addition, a pump motor can not work when the oil temperature and the oil level reach the pre-set value, which protects the oil tank and the oil pipeline of the motor, thereby prolonging the service life of the equipment.
Description
Technical field:
The utility model relates to a kind of driving machine oil temperature oil level supervising device.
Background technology:
The temperature and the oil level of traditional development machine fuel tank do not have monitor-control apparatus, in use can cause the too high or oil level of oil temperature to cross when low Oil pump electrical machinery still works, the work of Oil pump electrical machinery chronic fatigue, cause motor short serviceable life, the oil temperature is too high, cause the hydraulic pressure original paper to damage easily, thereby influence the serviceable life of whole development machine, bring very big economic loss to the user.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of driving machine oil temperature oil level supervising device is provided.It has solved does not have temperature and oil level monitor-control apparatus in the development machine fuel tank, problems such as development machine weak point in serviceable life.The purpose of this utility model is achieved in that driving machine oil temperature oil level supervising device is by Programmable Logic Controller, data line, LCD, oil return opening, hydraulic reservoir, inlet port, fuel level sensor, oil temperature sensor, shielded cable formation.Programmable Logic Controller is connected with LCD by data line, fuel level sensor, oil temperature sensor are installed in the hydraulic reservoir respectively, the fuel level sensor upper end is connected with Programmable Logic Controller by shielded cable respectively with the oil temperature sensor upper end, the downside of hydraulic reservoir is provided with inlet port, and upside is provided with oil return opening.This product structure is simple; can real-time monitor the situation of oily gentle oil level; the situation of oily temperature oil level in the fuel tank is shown on LCD intuitively; and in oil temperature, Oil pump electrical machinery can not be worked when oil level reached setting value; motor oil cylinder and oil pipe line are played protective effect, prolonged the serviceable life of equipment.
