Detailed Description
The present invention is further illustrated by way of example and not by way of limitation in the scope of the following examples in connection with the accompanying drawings.
As shown in fig. 1-2, the ship includes a water supply pump 11, a water using system 13, and a pressure water tank 12. Fig. 1 illustrates the normal freshwater system of a vessel. In the fresh water system, a pressure water tank 12 is connected between a water supply pump 11 and a water using system 13, the water supply pump 11 supplies fresh water, and the water using system 13 includes a hot water tank 14.
The water outlet ends of the water supply pump 11 and the pressure water tank 12 are provided with check valves 16.
If the pressure water tank 12 is maintained by a conventional method, the piping between the pressure water tank 12 and the water supply pump 11 needs to be disconnected, and the entire ship stops working.
The maintenance method of the embodiment includes the following operations:
bypassing the pressure water tank 12 and connecting the hot water tank 14 between the water supply pump 11 and the water usage system 13; and to let air through the hot water tank 14.
The hot water tank 14 is used instead of the pressure water tank 12 so that the vessel can be supplied with fresh water normally during maintenance of the pressure water tank 12.
The lower part of the hot water tank 14 stores water, the upper part is compressed air, after the water supply pump 11 stops supplying water, the compressed air applies pressure to the fresh water in the lower part, so that the water pressure provided by the hot water tank 14 is stable, the effect of normal water supply is achieved, and once the fresh water in the hot water tank 14 is reduced to a certain amount, the water supply pump 11 supplies water into the hot water tank 14 again.
The maintenance method further comprises the following operations: a sampling pressure gauge is provided on a pipe connecting the water supply pump 11 and the water using system 13, the sampling pressure gauge is electrically connected to the water supply pump 11 and the water supply pump 11 is started or stopped according to a detection result of the sampling pressure gauge.
The original sampling pressure gauge is arranged in the pressure water tank 12, and once the water pressure in the pressure water tank 12 is lower than a certain value, so that water cannot be normally supplied to the water using system 13, the water supply pump 11 is started to pump fresh water into the pressure water tank 12 again.
In this embodiment, a sampling pressure gauge is additionally provided and is provided on a pipe connecting the water supply pump 11 and the water using system 13, and whether the water supply pump 11 needs to be activated is determined according to the water pressure in the pipe, so that the hot water tank 14 can perform the same function as the pressure water tank 12.
The hot water tank 14 is provided with instrumentation where air is let into the hot water tank 14.
The hot water tank 14 has a duct in the meter that leads to the inside of the hot water tank 14, through which air is simply and conveniently injected into the hot water tank 14.
The maintenance method further comprises the following operations: the one-way valve at the water inlet of the hot water tank 14 is replaced by a two-way valve, and the valve at the water outlet of the hot water tank 14 is closed.
The water supply pump 11 is communicated with the water inlet of the hot water tank 14 using a first pipe 15.
The water using system 13 further includes: a water dispenser, a cooling water tank, a water tap and the like. The cooling water tank refers to a cooling water tank of various machines on a ship.
The hot water tank 14 is used to supply hot water for washing of crews. Since the hot water tank 14 is occupied, crews may not be able to take a hot bath on the ship during this time, but the bath is not needed and the ship can still sail normally.
The starting air pressure in the hot water tank 14 is the same as the starting air pressure in the pressurized water tank 12.
The volume of the hot water tank 14 is smaller than that of the pressure water tank 12, and the pressure water tank 12 is 1.5m3And the hot water tank 14 is 1m in general3The water storage amount of the hot water tank 14 is smaller than that of the pressure water tank 12, but the hot water tank 14 can adjust the compressed air pressure to be consistent with that of the pressure water tank 12 by adjusting the water storage amount, so that the water pressure of water supply is ensured.
