Abstract
The utility model relates to the field of pressure control of a water pump, in particular to a water supply pressure ensuring device for the water pump. The water supply pressure ensuring device is characterized in that: the water supply pressure ensuring device comprises a safety valve and a pressure sensor which are respectively arranged on an outlet pipeline of the water pump, wherein the safety valve is connected with a drain pipe, and the pressure sensor is connected with an industrial personal computer connected with an alarm device. Compared with the prior art, the water supply pressure ensuring device has the following advantages: when the pressure in the outlet pipeline of the water pump rises to the warning value, the alarm device in a pump room begins to send alarms to draw attention of an operator, and meanwhile the safety valve is started to relieve pressure for the pipeline so as to ensure the system safety and provide sufficient time for finding out reasons and handling problems; moreover, the device has the advantages of sensitive response and accurate pressure control.
Description
Technical field
The utility model relates to water-aspirator pressure control field, relates in particular to a kind of water pump pressure of supply water ensuring equipment.
Background technique
Suppress in the process at the supply channel of water pump,, can cause water pump and pipeline, pipe fitting to destroy explosion because manifold pressure sharply rises, for guaranteeing the normal startup and the operation of water pump, it is necessary that the pressure ensuring equipment is set in the water pump supply channel, at present, does not also have the application report of this respect.
Summary of the invention
The purpose of this utility model provides a kind of water pump pressure of supply water ensuring equipment, solves that water pump is suppressed, the pipeline inner pressure in the water supply process changes greatly, a uppity difficult problem.
For achieving the above object, the utility model is achieved through the following technical solutions:
Water pump pressure of supply water ensuring equipment comprises safety valve, pressure transducer, is respectively equipped with safety valve and pressure transducer on the exit of pump pipeline, and safety valve links to each other with waste pipe, and pressure transducer is connected with process control machine.
Described process control machine links to each other with alarm buzzer.
Compared with prior art, the beneficial effects of the utility model are: after exit of pump pipeline internal pressure is raised to warning value, the interior alarm buzzer of pump house begins the warning reminding operator and notes, safety valve starts pipeline is carried out release therebetween, guarantee security of system, for searching reason and handle the time that provides sufficient, the device reaction sensitivity, pressure control is accurate.
Description of drawings
Fig. 1 is the utility model example structure schematic representation.
Among the figure: 1-water pump 2-outlet line 3-gate valve 4-safety valve 5-pressure transducer 6-process control machine 7-alarm buzzer 8-waste pipe 9-feed valve 10-watering equipment
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
See Fig. 1, it is the utility model example structure schematic representation, water pump supplies water, suppresses system, water pump pressure of supply water ensuring equipment wherein, comprise safety valve 4, pressure transducer 5, gate valve 3, be respectively equipped with safety valve 4 and pressure transducer 5 on the outlet line 2 of water pump 1, safety valve 4 links to each other with waste pipe 8, and pressure transducer 5 is connected with process control machine 6 in the pump house.Also be provided with gate valve 3 between safety valve 4 and the outlet line 2.
Described process control machine 6 links to each other with alarm buzzer 7.
According to PRODUCTION STATUS, the operating pressure of safety valve 4 and pressure transducer 5 is made as between 1.25～1.5 times of water pump 1 working pressure, its working principle is:
1, when water pump 1 starts, pipeline inner pressure raises rapidly, when pressure rises to 1.25 times of working pressures, pressure transducer 5 sends signal, alarm 7 is given the alarm, and safety valve 4 starts and carries out release simultaneously, sees after waste pipe 8 water flowed out for 3 to 5 seconds and opens feed valve 9, starting mode of pump is finished, and supplies water for watering equipment 10.
2, system is when operation, can be because equipment and personal factor cause system pressure sharply to rise, the Security of water pump and pipeline is affected and causes damage, the same, after pipeline inner pressure is raised to setting value, alarm 7 beginning warning reminding operator note in the pump house, and safety valve 4 starts and pipeline is carried out release guarantees security of system therebetween, and judge whether to switch off the pump and 1 provide the sufficient time searching reason.
Claims (2)
1. water pump pressure of supply water ensuring equipment is characterized in that, comprises safety valve, pressure transducer, is respectively equipped with safety valve and pressure transducer on the exit of pump pipeline, and safety valve links to each other with waste pipe, and pressure transducer is connected with process control machine.
2. water pump pressure of supply water ensuring equipment according to claim 1 is characterized in that described process control machine links to each other with alarm buzzer.
