The control monitor unit of the hydraulic efficiency equipment of 10 boats and ships, 11 Hydraulic Pumps, 12 hydraulic power sources, 13 transfer valves, 14 hydraulic actuators, 15 pressure detectors, 16 electromagnetic proportional-type pressure-gradient control valves, 17 control panels, 18 hydraulic control portion, 19 telltales.
Detailed description of the invention
Next, with reference to accompanying drawing, detailed description of the invention of the present utility model is described.
As shown in Figure 1, the control monitor unit 10 of the hydraulic efficiency equipment of the boats and ships of an embodiment of the present utility model has: hydraulic power source 12, and described hydraulic power source 12 has multiple (being 4 in this embodiment) Hydraulic Pump 11; Multiple hydraulic actuator 14, described multiple hydraulic actuator 14 is connected with hydraulic power source 12 via transfer valve 13 respectively, and the drive source of each equipment as boats and ships; Pressure detector 15, described pressure detector 15 is arranged between each transfer valve 13 and the high hydraulic oil fuel feeding side of hydraulic actuator 14.Electric signal (electricity exports) from each pressure detector 15 is input to the hydraulic control portion 18 of the control panel 17 being positioned at boats and ships, carries out the control of each Hydraulic Pump 11 via electromagnetic proportional-type pressure-gradient control valve 16.
As Hydraulic Pump 11, use the Hydraulic Pump of the capacity-variable type be connected in parallel, these Hydraulic Pumps 11 are controlled by electromagnetic proportional-type pressure-gradient control valve 16, adjust the pressure of the hydraulic oil of discharging and are delivered to each transfer valve 13.Transfer valve 13 is hand valve (also can be electromagnetic valve) normally, carries out following action: 1) make hydraulic actuator 14 stop by lever operated; 2) oil is sent along positive dirction (such as rotating forward) or reversing sense (such as reversing) to hydraulic actuator 14; 3) adjustment is to the flow of the hydraulic oil of hydraulic actuator 14 conveying.
Pressure detector 15 detects the operation pressure of each hydraulic actuator 14, and this electric signal is delivered to control panel 17.Hydraulic actuator 14 is such as made up of hydraulic actuating cylinder or HM Hydraulic Motor, and pressure detector 15 detects the pressure corresponding with the load of each hydraulic actuator 14.Control panel 17 is provided with hydraulic control portion 18, records the pressure data detected by each pressure detector 15, and jointly export the data of record and time to telltale 19., the operation conditions of each hydraulic actuator 14 can be judged according to this pressure data (and time) here, and by the display of this operation conditions on the display 19.Then, this operation conditions is by control panel 17 record.
And, hydraulic control portion 18 detects maximum pressure (hydraulic pressure) P in the pressure (working hydraulic pressure of hydraulic actuator 14) detected by each pressure detector 15, send to electromagnetic proportional-type pressure-gradient control valve 16 to control, make the pressure of hydraulic power source 12 become maximum pressure P.In addition, in hydraulic control portion 18, according to pressure and the work-hours calculating Cumulative Elapsed Time of each hydraulic actuator 14, and show operation pressure and the Cumulative Elapsed Time of each hydraulic actuator 14 on the display 19.
Therefore, for the hydraulic actuator 14 of the pressure duty lower than maximum pressure P, carry out its pressure adjusting (that is, flow adjustment) with transfer valve 13, become the structure that hydraulic actuator 14 can maintain the load pressure of regulation.
Here, the selection of load is such as carried out with new transfer valve 13, when the pressure of each hydraulic actuator 14 be measured to by pressure detector 15 is the pressure lower than maximum pressure P, detect maximum pressure P1 (< P), electromagnetic proportional-type pressure-gradient control valve 16 is controlled with hydraulic control portion 18, the pressure of pressure source 12 is made to become P1, and, the supply pressure from each Hydraulic Pump 11 is reduced to P1.
Thus, the pressure from Hydraulic Pump 11 promptly switches, and therefore, energy ezpenditure reduces compared with the hydraulic structure of parallel hydraulic loop-type, and becomes by the electric signal in cable from the signal of each pressure detector 15.Therefore, it is possible to carry out the transmitting-receiving of signal with electric power, therefore, compared with the situation of the hydraulic piping of the control used in the past, operation becomes easy.
In addition, as previously mentioned, in control panel 17 (being hydraulic control portion 18 in detail), output from pressure detector 15 is added up, for each hydraulic actuator 14, calculate the Cumulative Elapsed Time (accumulated running time) from (when so-called boats and ships are intake at first) when bringing into use, as data logging in memory, and display on the display 19.
Thus, the period of service of known each hydraulic actuator 14, can calculate the inspection of hydraulic actuator 14 and the time of replacing before accident occurs.
In addition, the hydraulic control portion 18 of control panel 17 calculates the Cumulative Elapsed Time of each Hydraulic Pump 11, is stored in control panel 17, and display on the display 19.Thereby, it is possible to carry out maintenance inspection, the replacing of Hydraulic Pump 11.
Fig. 2 (B) represents the relation of the flow of the hydraulic oil in the tandem hydraulic loop of past case, pressure, required drive, and regardless of the flow of hydraulic actuator, (therefore, even a small amount of also) needs constant power.
Fig. 2 (C) represents the relation of the flow of the hydraulic oil in the parallel hydraulic loop of past case, pressure, required drive, regardless of the use pressure of each hydraulic actuator, needs the required drive corresponding with the flow of entirety.
On the other hand, employ structure shown in Figure 1 boats and ships hydraulic efficiency equipment control monitor unit 10 load-transducing formula hydraulic circuit in, as shown in Fig. 2 (A), required drive becomes the function of the flow of pressure and hydraulic oil, even if the one party in the flow of pressure and hydraulic oil is little, required drive also reduces.Further, even if there is multiple hydraulic actuator also not need the hydraulic piping controlled, therefore, it is possible to realize the simplification of hydraulic circuit.
The utility model is not limited to described embodiment, can change its structure in the scope not changing main idea of the present utility model.Such as, the utility model is not by the restriction of the number of Hydraulic Pump, the number of hydraulic actuator.
In addition, the incoming signal from each pressure detector can be carried out digital conversion by hydraulic control portion, calculates the Cumulative Elapsed Time of maximum force value and each hydraulic actuator with such as microcomputer, Programmable Logic Controller etc., and display over the display.In addition, the telltale be connected with control panel also can be multiple according to purposes.
