Description
Technical field
The present invention relates to a kind of tank stabilizer control gear, specifically tank stabilizer hydraulic power unit fluid level control device.
Background technique
As everyone knows, the degree of rocking when boats and ships generally all can install tank stabilizer to reduce ship's navigation.Tank stabilizer all can have hydraulic power unit usually, and hydraulic power unit needs to keep its liquid level tank stabilizer in certain scope normally to work usually, and hydraulic power unit just needs to install its fluid level control device.
At present, the tank stabilizer hydraulic power unit fluid level control device used in industry comprises controller, controller is connected with motor by wire, motor is connected with oil hydraulic pump by wire, oil hydraulic pump is connected with hydraulic system by wire, hydraulic system is connected with the first pressure transducer by wire, and the first pressure transducer is connected with described controller by wire.This tank stabilizer hydraulic power unit fluid level control device operationally, when the liquid level of hydraulic system drop to pressure reach the low pressure limit of the first pressure transducer detection range time, the low-voltage signal detected can be passed to controller by the first pressure transducer, controller can drive hydraulic pump works by actuating motor, oil hydraulic pump continues to hydraulic system force feed, and at this time the liquid level of hydraulic system will raise; When the liquid level of hydraulic system be increased to pressure reach the upper pressure limit of the first pressure transducer detection range time, the high-voltage signal detected will be passed to controller by the first pressure transducer, it is out of service that controller will control motor, oil hydraulic pump stops to hydraulic system force feed, and circulation just can keep tank stabilizer hydraulic power unit liquid level within the specific limits and so forth.But, this tank stabilizer hydraulic power unit fluid level control device the liquid level of hydraulic system drop to pressure reach the low pressure limit of the first pressure transducer detection range time, or the liquid level of hydraulic system is increased to pressure when reaching the upper pressure limit of the first pressure transducer detection range, if system jam, controller does not control motor running or stopping, now cannot differentiate that motor breaks down, or the first pressure transducer breaks down, or hydraulic system failure.When the system is operated, if the first pressure transducer breaks down, controller is by uncontrollable motor start and stop, oil hydraulic pump will continuously to hydraulic system pump oil, the liquid level of hydraulic system will continue to raise, and pressure continues to increase, and is easy to the damage causing hydraulic system.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of tank stabilizer hydraulic power unit fluid level control device, whether this tank stabilizer hydraulic power unit fluid level control device can utilize the action of the second pressure transducer to detect the first pressure transducer to break down, when the first pressure transducer breaks down, controller still can control motor start and stop, can avoid the damage caused because of the pressure Overpressure of a safety valve control range of hydraulic system.
For overcoming the above problems, provide following scheme:
Tank stabilizer hydraulic power unit fluid level control device of the present invention comprises controller, controller is connected with motor by wire, motor is connected with oil hydraulic pump by wire, oil hydraulic pump is connected with hydraulic system by wire, hydraulic system is connected with the first pressure transducer by wire, and the first pressure transducer is connected with described controller by wire.Its feature is that described hydraulic system is also connected with the second pressure transducer by wire, and the second pressure transducer is connected with described controller by wire, and the scope of the second pressure transducer detected pressures is greater than the scope of the first pressure transducer detected pressures.
Described first pressure transducer can detect the pressure of hydraulic system, when the pressure of hydraulic system reaches the upper limit or the lower limit of the first pressure transducer pilot pressure, the pressure signal detected can be converted into electric signal transmission to controller by the first pressure transducer.
When motor continuous service two minutes or motor are after two minutes out of service, controller does not receive the pressure signal that the first pressure transducer detects, will start the second pressure transducer.Second pressure transducer can detect the pressure of hydraulic system, and when the pressure of hydraulic system reaches the upper limit or the lower limit of the second pressure transducer pilot pressure, the pressure signal detected can be converted into electric signal transmission to controller by the second pressure transducer.
The electrical signal that described controller can be sent according to the first pressure transducer received or the second pressure transducer, controls described motor running or stopping.When the pressure of hydraulic system reaches the CLV ceiling limit value of the first pressure transducer or the second pressure transducer pilot pressure, controller controls motor to be stopped.When the pressure of hydraulic system reaches the lower limit of the first pressure transducer or the second pressure transducer pilot pressure, controller controls motor running.When the electrical signal that controller receives be sent by the second pressure transducer time, controller can send the alarm that the first pressure transducer breaks down.
Described motor can control oil hydraulic pump action, pump oil in described hydraulic system.
Wherein, the scope of the first pressure transducer detected pressures is 6 ~ 9MPa, and the scope of the second pressure transducer detected pressures is 5.5 ~ 9.5MPa.
Adopt above scheme, have the following advantages:
Because the hydraulic system of tank stabilizer hydraulic power unit fluid level control device of the present invention is also connected with the second pressure transducer by wire, second pressure transducer is connected with described controller by wire, and the scope of the second pressure transducer detected pressures is greater than the scope of the first pressure transducer detected pressures.Because the scope of the second pressure transducer detected pressures is greater than the first pressure transducer, then the second pressure transducer detects that pressure is prescribed a time limit higher than the upper limit of its detection range or lower than the lower of its detection range, the pressure of hydraulic system has exceeded the scope that the first pressure transducer detects, and so just can determine that the first pressure sensing there occurs fault.Due to the first pressure transducer break down after detected by the second pressure transducer, when doing so avoids system cloud gray model, the hydraulic system pressure caused because the first pressure transducer breaks down continue strengthen, hydraulic system is not easily damaged.
