Description of drawings
Fig. 1 is a system construction drawing of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1, the utility model is by water service pump 1, electric cabinet 3, flow velocity compensator 4, water signal picker 7, pressure signal collector 2.Micro computer and frequency converter are housed in the electric cabinet, are provided with positive depressor 5 and level sensor 6 in the flow velocity compensator 4.
Water service pump 1 water inlet joins with water supply system by shutoff valve 8 and check valve 9, and water outlet and flow velocity compensator 4 water inlets join, and the water outlet water receiving tap 10 of flow velocity compensator 4 joins.
Be connected to pressure signal collector 2 in the pipeline between water service pump 1 and the flow velocity compensator 4; Be connected to water signal picker 7 in the pipeline between flow velocity compensator 4 and the water cock 10.
Water signal picker 7, level sensor 6, the signal output part of pressure signal collector 2 is connected with the signal input part of micro computer in the electric cabinet 3 respectively.
Frequency converter output in the electric cabinet 3 links to each other with the input of water service pump 1.
Principle of work of the present utility model:
When water pump 1 is not worked, leading 10 the time when fetching boiling water, (water signal picker 7) senses flowing of water in the pipeline under the effect of flow velocity compensator 4, and export a working signal to micro computer, micro computer makes the operation of water pump 1 soft start at the signal that reads (pressure signal collector 2) after logic discrimination output actuation signal is controlled frequency converter, and reaches constant pressure water supply according to the rotating speed of water needs control water pump 1.After closing water cock 10 (water signal picker 7) export again a danger signal to micro computer make water pump 1 the time-delay a period of time after (adjustable) slowly quit work.
When unmanned water, when making water in the flow velocity compensator reduce to a certain amount of because of system leak (adjustable), magnetic level sensor 6 outputs one working signal is to micro computer, water pump 1 starts moisturizing, magnetic level sensor 6 is exported a danger signal again to micro computer after the water benefit is full, and water pump 1 quits work.
When system produced negative pressure, positive depressor 5 self-openings were to guarantee when the leading water energy proper flow 10 time of fetching boiling water.
For prevent that repeating open and close water cock 10 at short notice makes the water pump frequent starting, quits work after water pump 1 automatic time delay (adjustable) a period of time again when closing water cock 10 at every turn.
Effectiveness test of the present utility model and real ship use:
Real ship has been done test of many times on No. 34 wheels in harbour, we find in test, because the command signal of this system has current to produce, and after water pump quits work for a long time, because the star in addition of the leakage of system's sucking hole and total system leaks, water in the water pipe can constantly reduce, and can not produce signal because of current are too little during tap and makes system's cisco unity malfunction when water reduces to a certain amount of fetching boiling water again.We design and have made a flow velocity compensator for this reason, and press dress magnetic level sensor on the flow velocity compensator, and when the water in the flow velocity compensator will leak, the magnetic level sensor is exported a signal made starting mode of pump to replenish water.
The another one problem is to produce negative pressure in the system because of leakage makes, when fetching boiling water tap, water can't flow out and can not produce signal and make system's cisco unity malfunction, in order to prevent to produce negative pressure because of leakage makes system, we design on the flow velocity compensator and have made a positive depressor and eliminated negative pressure automatically.
Cause the water pump frequent starting in order to prevent frequent switch water cock again, we have installed delay timer additional and water pump have delayed time quit work behind the certain hour after cutting out water cock again.
This complete equipment has passed through repeatedly effectiveness test and constantly improvement from manufacturing experimently success, uses through real ship at last, has reached research purpose and designing requirement, has now dropped into normally on No. 51 wheels in harbour and has used, and lays the foundation for promoting the use of widely.
