Technical field
The invention belongs to fire supply system technical field, particularly a kind of fire water pump flow and pressure ATE.
Background technique
Along with the attention of fire supply system, need to pay close attention in fire supply system the fire water pump playing " heart " and act on, guarantee the reliability in its engineering operation.Except needing except reliable startup when ensureing fire water pump fire in the design of structural fire protection engineering, also need to strengthen fire water pump project installation and maintenance management at ordinary times.This is mainly reflected in the test, the monitoring aspect that fire-fighting are pumped to water flow and pressure.
In traditional fire supply system, the developmental tube of fire service pump or temporary facility is adopted to test the operating mode (flow and lift) of fire service pump.The situation that this is less for fire service pump flow, lift is not high, this mode less expensive.At present, propose in new NBS " fire supply and hydrant system technical specification " GB 50974-2014, one group of fire service pump should arrange flow and pressure test device in fire water pump house.To the situation that fire service pump flow is comparatively large or pressure is higher, propose to adopt fixed instrumentation to test.The control of its test is also in manually operated state.
The operating mode of fire service pump is embodied on flow on system fire service pump outlet pipe and pressure.On the one hand, fire service pump needs the detection identification by scene after project installation; On the other hand, fire service pump is after operation a period of time, and its performance, operating mode also can change, and whether the flow of water outlet and pressure meet the requirement that system fire-fighting is arranged, and this also needs its performance of periodic monitoring.From the angle of strengthening maintenance management at ordinary times, be necessary carry out Monitoring and Controlling to the test of fire service pump and safeguard automatically.
Along with the arrival in internet+epoch, this is also conducive to adopting fire communication transmission to be connected by thing thing, is conducive to remote monitoring, Timeliness coverage problem, to solve in time.
The key technology of this invention is the automatic test problem solving fire water pump flow and pressure.Except automatically testing, controlling, also can by flow, pressure by sensor transmissions to network, there is the effect of monitoring, be also integrated with system and the monitoring of fire water pump, the integration unit of fire communication transmission technology.
In prior art, mortor operated valve inherently has far away control of acceptance and opens, opens function; Flow transmitter itself has teletransmission display flow and on-the-spot display traffic engineering capability, does not belong in protection scope of the present invention.
This device can be arranged on fire supply pipeline, and mortor operated valve has the function accepting far to control to open, open.When fire service pump normally runs, mortor operated valve has the function of positive closing.Non-test state, mortor operated valve should be in closed condition.
In such scheme, water pipe, mortor operated valve, pressure transmitter, pressure gauge, flow transmitter can vertically, level or revolution install, installation form is not limit.
Beneficial effect of the present invention is: described device can improve fire supply system reliability of operation, and the automatic test of the water supply flow that can realize fire supply system and pressure, and can in real time, remote monitoring and control.Described device makes the operation of fire water pump, maintenance has more automation, intellectuality, thing connectionization.The image data of fire water pump can also upload to cloud process, consistent with the development of smart city.
Summary of the invention
Technical problem to be solved by this invention there is provided a kind of fire water pump flow and automatic pressure-testing device, this system and device have and automatically carry out fire water pump flow and pressure test, the function having monitor and forecast, have flow and pressure information collection, have information transmission, also has the function of the display of flow and pressure.This device can be used in fire water pump house, by the pressure of water supply condition, flux signal teletransmission to Fire Services Communication Centre or urban fire protection alarm network center, can carry out image display to the operating mode of system water supply.
For solving the problems of the technologies described above, basic conception of the present invention is:
A kind of fire water pump flow and automatic pressure-testing device, fire supply pipeline connects mortor operated valve, pressure transmitter, pressure gauge and flow transmitter, and connecting order is that independent assortment is installed; Shell encases described mortor operated valve, described pressure transmitter, described pressure gauge and described flow transmitter and assembles entirety; Described fire supply pipeline penetrates from one of described shell, and another place passes; Described shell is provided with releases the button and pressure gauge viewing window, and described pressure gauge viewing window is corresponding with described manometric surface location.
Based on above-mentioned basic scheme, proposing apparatus pressure transmitter, manometric measuring accuracy are 0.5 grade, and 75% of maximum range should be greater than 165% of the design pressure value of a maximum fire-fighting pump-feeding; The measuring accuracy of described flow transmitter should be 0.4 grade, and 75% of maximum range should be greater than 175% of the design flow value of a maximum fire service pump.
