However, when the liquid level control device of this anti-rolling water tank hydraulic pump station drops to the pressure of the hydraulic system and reaches the lower limit of the detection range of the first pressure sensor, or the liquid level of the hydraulic system rises to the pressure of the first pressure When the pressure upper limit of the sensor detection range, if the system fails, the controller does not control the motor to run or stop. At this time, it is impossible to judge whether the motor is faulty, the first pressure sensor is faulty, or the hydraulic system is faulty.
When the system is running, if the first pressure sensor fails, the controller will not be able to control the motor to start and stop, the hydraulic pump will continue to pump oil to the hydraulic system, the liquid level of the hydraulic system will continue to rise, and the pressure will continue to increase. Large, it is easy to cause damage to the hydraulic system

The invention relates to an anti-rolling tank hydraulic pump station liquid level control device. The anti-rolling tank hydraulic pump station liquid level control device comprises a controller. An electromotor is connected to the controller through a wire. A hydraulic pump is connected to the electromotor through a wire. A hydraulic system is connected to the hydraulic pump through a wire. A first pressure sensor is connected to the hydraulic system through a wire and is connected with the controller through a wire. The anti-rolling tank hydraulic pump station liquid level control device is characterized in that a second pressure sensor is connected to the hydraulic system through a wire, and the controller is connected with the second pressure sensor through a wire. The pressure detection range of the second pressure sensor is larger than that of the first pressure sensor. Whether the first pressure sensor has faults or not can be detected through movement of the second pressure sensor; when the first pressure sensor has faults, starting and stopping of the electromotor can still be controlled by the controller, and damage caused when the pressure of the hydraulic system is not within the pressure control range can be avoided.
Description
technical field [0001] The invention relates to a control device for an anti-rolling water tank, in particular to a liquid level control device for a hydraulic pump station of an anti-rolling water tank. Background technique [0002] As we all know, anti-rolling water tanks are generally installed on ships to reduce the degree of shaking when the ship is sailing. The anti-rolling water tank usually has a hydraulic pump station, and the hydraulic pump station usually needs to maintain its liquid level within a certain range to stabilize the water tank to work normally, and the hydraulic pump station needs to install its liquid level control device. [0003] At present, the liquid level control device of the anti-rolling tank hydraulic pump station used in the industry includes a controller, the controller is connected to the motor through the wire, the motor is connected to the hydraulic pump through the wire, the hydraulic pump is connected to the hydraulic system through t...
