It is very important that constant pressure water supply system supplies water for municipal water supply, high rise building water supply and some special users.If the too high meeting of city pressure causes pipelines from bursting, hypotony then can make tap water can't arrive in the higher resident family in inhabitation position, influences people's normal life.And for example when fire alarm takes place,, can not put out a fire rapidly, possibly cause heavy economic losses and casualties if pressure of supply water is not enough or anhydrous supply.So the employing constant pressure water supply system has bigger economy and social effect.
Present employed constant pressure water supply system generally comprises water storage device, water pump, water pump suction inlet pipe and pump water conductor, is installed in pressure sensor and water supply control apparatus on the pump water conductor.At present, water supply control apparatus adopts the work of converter technique control of pump motor more, to reach energy-conservation effect.This constant pressure water supply control device comprises PLC control module, pump motor control module, frequency control module, power module.Said pressure sensor is electrically connected with the input of PLC control module; Power module is electrically connected with the power input of PLC control module, pump motor control module, frequency control module; The output of PLC control module is electrically connected with pump motor control module, frequency control module; The output of frequency control module is electrically connected with the input of pump motor control module, and the output of pump motor control module is electrically connected with pump motor.
In constant pressure water supply system, often have the situation that the water pump installation site is higher than water storage device, this moment, needing water pump to have certain suction capacity could discharge water because the water pump suction inlet is higher than water storage device.But mostly present employed water pump is centrifugal water pump, and no suction capacity needs artificially in pipeline, to pour water and could the water in the water storage device be discharged, and wastes time and energy very much; If exist dirt that the water pump suction inlet is blocked in the water storage device, water pump can produce cavitation pitting at the suction inlet place of pump because suction resistance is excessive and inhale, and influence the normal use of water pump, also can inhale sky and water pump is burnt owing to water pump when serious.
Summary of the invention
The purpose of the utility model is to overcome the weak point of prior art, provide a kind of can the automatic diversion of feed pump and can stolen goods occur at the suction inlet pipe and stop the novel constant pressure water supply system that pump operation guarantees water pump safety when stifled.
The purpose of the utility model is achieved in that
A kind of novel constant pressure water supply system; Comprise water pump suction inlet pipe, water pump, pump outlet tube, pressure sensor and constant pressure water supply control device; Said pressure sensor is installed on the pump outlet tube and with the constant pressure water supply control device and is electrically connected; The vacuum pump that one liquid level sensor and is connected with the suction inlet pipe is installed on said water pump suction inlet pipe, and said liquid level sensor and vacuum pump are electrically connected with the constant pressure water supply control device.
And said constant pressure water supply control device comprises PLC control module, pump motor control module, suction motor control module, frequency control module, power module.Said pressure sensor and liquid level sensor are electrically connected with the input of PLC control module; Power module is electrically connected with the power input of PLC control module, pump motor control module, frequency control module; The output of PLC control module is electrically connected with pump motor control module, suction motor control module and frequency control module; The output of frequency control module is electrically connected with the input of pump motor control module, and the output of pump motor control module is electrically connected with pump motor.
The advantage and the good effect of the utility model are:
1, native system is equipped with the vacuum pump that a liquid level sensor and is connected with the suction inlet pipe on water pump suction inlet pipe, in the time of therefore can coming into operation in system water pump is vacuumized diversion, need not artificial diversion, has therefore greatly saved manpower, has simplified operation.
2, native system occurs dirtyly when stifled at water pump suction inlet pipe, can stop the operation of water pump, avoids the damage of water pump, has increased the security row of system.
3, the utility model design science is reasonable, and is simple in structure, easy for installation, and simplified operating process, reduced labour intensity, effectively improved the safety and the reliability of system.
Description of drawings
Fig. 1 is the sketch map of the utility model;
Fig. 2 is the theory diagram of the utility model constant pressure water supply control device.
The specific embodiment
Be described in detail the embodiment of the utility model below in conjunction with accompanying drawing; Need to prove that present embodiment is narrative, is not determinate, can not limit the protection domain of the utility model with this.
A kind of novel constant pressure water supply system, as shown in Figure 1, comprise water storage device 1, water pump 5, water pump suction inlet pipe 2, pump water conductor 6, be installed in pressure sensor 7 and constant pressure water supply control device 8 on the pump water conductor.Said constant pressure water supply control device comprises PLC control module, pump motor control module, frequency control module, power module.Said pressure sensor is electrically connected with the input of PLC control module; Power module is electrically connected with the power input of PLC control module, pump motor control module, frequency control module; The output of PLC control module is electrically connected with pump motor control module, frequency control module; The output of frequency control module is electrically connected with the input of pump motor control module, and the output of pump motor control module is electrically connected with pump motor.Foregoing is prior art, repeats no more.
The innovative point of the utility model is:
1, the vacuum pump 4 that a liquid level sensor 3 and is connected with the suction inlet pipe is installed on water pump suction inlet pipe, said liquid level sensor and vacuum pump are electrically connected with the constant pressure water supply control device.
2, the constant pressure water supply control device is set up a suction motor control module; Said liquid level sensor is electrically connected with the input of PLC control module; Power module is electrically connected with the power input of suction motor control module; The output of PLC control module is electrically connected with the suction motor control module, and the output of suction motor control module is electrically connected with suction motor.
The operating principle of this system is:
Starting system, liquid level sensor is delivered to the PLC control module with the anhydrous signal of detected water pump suction inlet pipe, and the starting of PLC control module control vacuum pump vacuumizes diversion for water pump.Liquid level sensor is delivered to the PLC control module with this information after treating to be full of water in the water pump suction inlet pipe; The PLC control module is sent a control instruction and is stopped the vacuum pump running; Send instruction to the pump motor control module simultaneously, the starting water pump, water system gets into normal operating conditions.
When water pump suction inlet pipe occurs dirtyly when stifled, the water yield in the water pump suction inlet pipe reduces, when the water in the water pump suction inlet pipe can't contact with liquid level sensor; Liquid level sensor is delivered to the PLC control module with detected anhydrous signal; The starting of PLC control module control vacuum pump vacuumizes diversion for water pump and stops the running of water pump, after the process certain time-delay, when water level still can't reach the position of liquid level sensor; System can send sound and light alarm, and the notifying operation personnel carry out trouble shooting.Avoid water pump because of the burning of dirty stifled cavitation pitting that produces of suction inlet or water pump, effectively guaranteed the safety of equipment, improved the reliability of system.
