The drainage pump 1 contains a porous pipe 24, brought into the tank 19 of the bilge water, and a suction pipe 23, connected to the receiving valve 4-6 with drain wells 20-22. A pressure sensor 3 is installed on the pressure pipe 24, not 19 bilge water and waste wells 20-22 are placed in the cistern of upper levels. In the sewage wells 20–22 there are also sensors 16–18 of the lower levels. Position Outlet The automatic two-position re-plugger 10 is connected via the disconnecting contact of the sensor 11 of the upper level of the bilge water tank 19 to the common bus 27, which is / 1; further connected to the first terminals of the closing contacts of the sensors 12-14,304 level wastewater coders 20-22 respectively, to the first terminals of the first closing contacts of sensors 16–18 of the lower levels of sinks 20-22, to the first terminals of the contact contacts of the pressure sensor 3 and the first sensor HOiO sensor 4, the second conclusions of the closing contacts of sensors 12–14 of the upper levels GOVERNMENTAL wells 20-22 are connected to the common bus 28 to each other and connected to the first terminal of the second lower waste levels 1kolodtsev 20-22, the locking sensor contacts 16-18 to the first terminals of the first switching contacts of the receiving valve sensors 4-6.

The first output of the closing contact of the sensor 11 is the upper level of the bilge water tank connected to the output of the Dip Switch 10. The proposed automated vessel the drainage system is designed to collect water containing

petroleum products, i.e. when drainage ejectors cannot be used, because the volume of bilge water tanks is limited, and the process of drying when using ejectors occurs due to supplying water from the fire-fighting water system 1 under high pressure and the suction effect on the ejector receiving pipe, i.e. bilge water from the fire water system is added to a large volume of water. waste wells.

The proposed system provides for the collection of bilge water in a special

a bilge water tank from which water containing petroleum products is to be cleaned and discharged overboard. The process of bilge water purification and the discharge of purified water overboard is not considered in this system. The system used as a reception} P) 1x valves 4-6 spring-loaded valves that control the EPR with one input. These valves are open if a continuous signal arrives at the EPR inputs 7–9, and when it is removed, its receiving valves 4–6 are closed by the action of a spring. The system uses an element of delay 25, which generates a pulse signal at the output in the presence of a continuous signal at its input. When the continuous signal is removed from the input of the DELAY element, it returns to its original state, i.e. With a new arrival at its input of a continuous signal, the DELTA element will again form a single pulse signal. The need to use the DELAY element is that, in the initial state, the pressure sensor 3 and the receiving valve sensors h-6 (when the two-position switch 10 is set to Auto) form a continuous signal to the second input from the magnetic starter 2 of the drainage pump 1, which prevents Do not run this pump.

The system indicates the passage of a signal from one power pole, since the second power pole is connected to the E11P 7-9 and the magnetic starter directly, which simplifies the system and description of the system operation.

In the initial state of the system, the 19 bilge water and wastewater system () 6

boats Deputy, 1 and 10), the KOHIacts of the sensors of the upper 11–14 and lower 16–18 levels are in the initial state (Fig. 11. 5 E – 7–7 are de-energized, i.e., there are no signals at their inputs. Reception valves 4-6 are closed and the contact status of the sensors of these valves is as indicated in Fig. 1. Osushi pump i does not work and no

The connections are on the pressure pipe 24. Pressure sensor 3 is in the initial state (its open contact is closed),

When fed to the power system and

installing the two-position switch 10 to the position The automatic signal from its output receives a continuous signal, which through the size1 of the 0 contacts of the upper level sensors 1 of the bilge water tank 19 goes to the common bus 27 and then to the first terminals of the closing contacts of the sensors 12-14 of the upper levels of the drainage blocks 20-22 to the first terminals of the first, pinning contacts of sensors 16-18 of the lower levels of manhole wells 20-22, the first leads of the disconnecting contacts of the sensor of the first (conditionally) receiving cell; Shan 4 and pressure sensor 3. This signal is then transmitted through successively connected closed spans) 1: 1 (the sensor contacts of the receiving valves 4 and 5 to the first input of the OR 15 element, to another input of which the signal also comes through the closed disconnecting contact of the pressure sensor 3. At the output of the OR i5 element there is a continuous signal that goes to the item FOR; 1 HOLD 25. The DELAY 25 element transmits a signal, for example, with a duration of S seconds to the second input C of the magnetic actuator 2, which stops the drainage pump 1, which has been turned off. Res issuing a stop signal to the input C of the magnetic actuator 2. This command does not produce, as a way, no inclusions.

With the appearance of water, for example. In cTO4HbJx wells 20 and 21, sensors 16 and 17 of the lower levels are triggered, which close their first and second closing contacts. Through the first 5 closing coggings of sensors 16

and: 7 low levels will pass the signals that go to the first terminals of the second locking contacts of the sensors of the receiving terminals 4 and 6, respectively. As vod accumulates in the waste wells 20 and 21 in one of them, a sensor will operate, for example, 12 upper levels of the drain well 20, which will close its closing contact and, thus, the common bus 28 will be under the action of a continuous signal (under the potential Taking into account that the common pins 28 are connected with the first pins of the second closing contacts of sensors 16. And the 17 lower levels of manholes 20 and 2, these contacts will pass the signals and go to the EPR inputs 7 and 8 of the receiving valves 4 and 5, respectively. The latter will open and close the circuit The contacts of their sensors as well as the opening contacts are opened. By means of the first closing contacts of the sensors of the receiving valves 4 and 5, the common bus 26 will be under the action of a continuous signal under the receiver, i.e. the signal will go to the first input II of the magnetic starter 2 of the drainage pump 1 Simultaneously, by means of the second closing contacts of the sensors, the receiving valves 4 and 5 and the first close contacts of the sensors 16 and 17 of the lower levels, respectively, the EPR inputs 7 and 8 are connected to the common bus 27 and stand on self-blocking s period during drainage wastewater to lodtsev 20 and 21. By pasNfcikayuschih contacts receiving sensors 4 and valves 5 razomknets chain odds ble to stop the drainage pump 1, that is, e. the first input element OR 15 will not be under the action of a continuous signal. After the intake valves and 5 are opened and the drainage pump 1 is started, the drainage wells 20 and 21 will start drying, and the pressure drainage pump 1 will build up on the support pipe 24. The pressure sensor 3 will operate and open its normally closed contact, which ensures that a continuous signal is applied from one of the inputs of the OR 15 element. Since the 19 bilge water tank is empty, its sensor; 11 of the upper level is in the initial state and at the last input of the element OR 13 there will also be no signal, and consequently, at the 08 output;) Lemeite I.CH 15, and at} (the element of DELAY 25 will also lack the signal, which causes A: 1 pin DELAY is the initial state and ensures reception of the signal. After the drying process is started in the waste well 20, the sensor will return to the upper level 21, i.e. the freezing contact will open, which will de-energize the common tires 28. Thus, all the circuits are connected data to bus 28 will be de-energized, i.e. will not be affected by a continuous signal, which will lead to the removal of the signal from the first input II of the magnetic starter 2, the start of the dehumidification pump I (thermal protection eroj is provided and from the EPR inputs 7-8 that were previously connected to the common bus 28. However, the EPR 7 and 8 were self-locking and are connected to the common bus 27 (indicated by Bbmie. Then the drain well 21 will be drained because there is less water than it does 20, and the sensor 13 of the upper level did not work. When draining the waste well 21, its low level sensor 17 will return to its initial state and open its closing contacts, which will break the EPR 8 self-blocking, which was connected via the closing contacts of the .1 7 low level sensor and the receiving valve sensor 5 to the common bus 27. The intake valve 5 will close under the action of the spring and will reset its contacts to its original state. Then the drainage well 20 will be drained, the sensor of the lower ur. 16 ov which will also come to its initial state, i.e. will open its closure contacts. There will be a violation of the self-locking of the EPR 7 pitcher, i.e. Removing the continuous signal from its input, which came from the common bus 27 through the closed contacts of the sensors 16 of the lower level and the receiving valve 4. The receiving valve 4 closes under the action of the spring and will reset its sensor KOHTaKTiji. This will ensure that the signal from the common bus 27 passes through the series-connected disconnecting contacts of the sensors of the receiving valves 4-6, through the element OR 15 and the KA DELTA element 25 to the second input C of the magnetic actuator 2 stops the drying pump 1. As mentioned above, the signal through the element DELAY 25 will take a short duration, for example in 1 s. The pressure in the discharge pipe 24 will drop, which will reset the pressure sensor 3, which will close its first contact and connect the common bus 27 to another input of the OR 26 element, but one of the inputs of the OR 15 element will already be under the influence of a continuous signal i.e., the appearance of a continuous signal at another input of the element OR 15 will not result in any new switches. The drying process is complete. The system returned to its original state. When performing the drying process, it is obvious that the pressure sensor 3 provides the functions of duplicating the stopping of the drying pump 1. Duplicating the stopping of the drying pump i is performed in order to ensure that it stops when it can be adjusted. valve sensors 4-6, i.e. a signal to stop the drying pump 1 is not generated. In this case, in the pressure pipe 24, as in the receiving pipe 23, a vacuum will be created, which will reset the pressure sensor 3 to its initial condition Open 5x contacts. Tacles are possible due to the breakage of any receiving valve and its non-closing of the catch in the air intake pipe 23, which will also lead to a drop in pressure in the pressure pipe 24 and the arrival of the pressure sensor 3 in the initial state. Thus, the drainage of the waste well 22 proceeds in the same way as the ocymeime of the waste wells 20 and 21. During the drainage of the drain wells 20-22, the hold water tank 19 can occur before the upper level sensor I1 is pumped, i.e. No. 1 scan his contact: contact and open the contact of his contact. 3010 In the case of a disconnecting contact of the upper level sensor 1, the continuous signal supply circuit from the position of the Two-way switch 10 to the common bus 27, and therefore also the common buses 26 and 28, breaks, causing the system to go off, i.e. to close the valves 4-6 (if they were open) and to remove the signal from the first input II of the magnetic starter 2 if a signal came to it. At the same time, through the closing contact of the sensor 11 of the upper level of the tank 19 of the bilge water, the axial pump 1 will be shut down {the shutdown circuit was considered to be EH. Thus the drying process will be terminated, which requires operator intervention to empty the 19 bilge water tank. The alarm circuits for the operation of the drainage pump 1, the open and closed states of the receiving valves 4-6, the conditions of the drainage wells and the cisterns, bilge waters are constructed according to known principles and therefore are not considered in this system. In comparison with the known device, when filling up to the upper level of at least one waste well, there is an axle extraction of all the drainage wells in which the sensors of the lower levels have been activated. This ensures a reduction in the number of system responses and, consequently, the start and stop of the drainage pump, ITG expands the functionality of the systems and increases the service life of the drainage pump. Starting the drainage pump is provided by any high level alarm, i.e. when the drying process starts, the upper level sensor comes back to its original state and prevents the signal from being sent to the start of the drainage pump, providing it with thermal protection in the event of its activation. The formation of a short-term signal to stop the drainage pump is provided by the DELAY element entered into the system.
