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 tank stabilizer reduces ship's navigation generally all can be installed on boats and ships.Tank stabilizer all can have hydraulic power unit conventionally, and hydraulic power unit need to keep its liquid level tank stabilizer in certain scope to work conventionally, and hydraulic power unit just need to be installed its fluid level control device.
At present, the tank stabilizer hydraulic power unit fluid level control device using 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 is when work, when the liquid level of hydraulic system drops to pressure and reaches the low pressure limit of the first pressure transducer detection range, the first pressure transducer can pass to controller by the low-voltage signal detecting, 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 is increased to pressure and reaches the upper pressure limit of the first pressure transducer detection range, the first pressure transducer will pass to controller by the high-voltage signal detecting, it is out of service that controller will be controlled 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 is when the liquid level of hydraulic system drops to pressure and reaches the low pressure limit of the first pressure transducer detection range, or the liquid level of hydraulic system is when being increased to pressure and reaching the upper pressure limit of the first pressure transducer detection range, if system breaks down, controller is not controlled motor operation or is stopped, now cannot differentiate motor and break down, or the first pressure transducer breaks down, or hydraulic system breaks down.When system is moved, if the first pressure transducer breaks down, controller is by uncontrollable motor start and stop, oil hydraulic pump will be 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 cause the damage of 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 and break down, when the first pressure transducer breaks down, controller still can be controlled motor start and stop, the damage that can avoid the pressure Overpressure of a safety valve control range because of hydraulic system to cause.
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 the first pressure transducer can detect the pressure of hydraulic system, when the pressure of hydraulic system reaches the upper limit of the first pressure transducer pilot pressure or lower limit, the first pressure transducer can be converted into electric signal transmission to controller by the pressure signal detecting.
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, and will start the second pressure transducer.The second pressure transducer can detect the pressure of hydraulic system, and when the pressure of hydraulic system reaches the upper limit of the second pressure transducer pilot pressure or lower limit, the second pressure transducer can be converted into electric signal transmission to controller by the pressure signal detecting.
The electrical signal that described controller can be sent according to the first pressure transducer receiving or the second pressure transducer, controls described motor operation or stops.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 is controlled motor and is stopped.When the pressure of hydraulic system reaches the lower limit of the first pressure transducer or the second pressure transducer pilot pressure, controller is controlled motor operation.The electrical signal receiving when controller is while being sent by the second pressure transducer, and controller can send the alarm that the first pressure transducer breaks down.
Described motor can be controlled oil hydraulic pump action, to 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, 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.Because the scope of the second pressure transducer detected pressures is greater than the first pressure transducer, the second pressure transducer detect pressure higher than the upper limit of its detection range or lower than its detection range lower in limited time, the pressure of hydraulic system has exceeded the scope of the first pressure transducer detection, so just can determine that fault has occurred the first pressure sensing.Because the first pressure transducer is detected by the second pressure transducer after breaking down, while so just having avoided system operation, because the first pressure transducer hydraulic system pressure causing that breaks down continues increasing, make hydraulic system be difficult for being damaged.
