Embodiment 1

[0034] Integrated electrical and mechanical start pump device, if included figure 1 As shown, including the power supply system, a pump switching system, a mechanical start-pump system, an electrical setup system, a motor and control system, a power supply system and a pump switching system, and the pump switching system is separately connected to the mechanical starting pump system, electrical lane System connection, mechanical start pump system, electrical start pump system is connected to the motor. The pump switching system is used to switch the mechanical start pump system and the electrical start system, and the power system is used to power the motor to the motor by the electrical setup pump system or mechanical start pump system after the pump system, that is, when the pump switching system is switched. When the system is bucking, the motor is booted by the power supply system, and the anti-pressing start is started; when the pump switching system switches the mechanical s...

Embodiment 2

[0038] The present embodiment is different from the first example:

[0039] Control systems include storage modules, associated filter modules, recording modules, and recommended filter modules, such as attached figure 2 Indicated.

[0040] The storage module pre-stored area water pump information and maintenance record table, the area pump information includes the pipe network information of each water pump and the water pump coordinates of each water pump, the maintenance record table records the planned maintenance date, maintenance date and overhaul, maintenance record table The pump is marked as an index to store.

[0041]The control system is also used to obtain fireplaces, and screen the associated water pump according to the fireplaces and regional water pump information. The fire site is uploaded by the fire management department through the main control terminals used, such as a computer. Specifically: the associated screening module presets the number of overhaul quanti...

Embodiment 3

[0051] The difference between this embodiment and the second embodiment is:

[0052] The control system also includes a power storage filter module, a power storage module is used to extract the next maintenance date in the overhaul record table, and the next inspection date is a plan for maintenance record table. The power storage module is also used to calculate the time difference value of the next time the date and the current date. When the time difference is less than the preset time threshold, the corresponding associated water pump corresponding to the power supply water pump. In this embodiment, the time threshold is 15 days. The control system is also used to control the power supply module corresponding to the electric water pump to supply power to the electric storage module.

[0053] In other embodiments, the power storage module is also used to match the water pump to be powered and recommended, and update the water pump to be powered according to the matching item. ...

Abstract

The invention relates to the technical field of pump starting, in particular to an integrated electrical and mechanical pump starting device. The integrated electrical and mechanical pump starting device comprises a power supply system, a pump starting switching system, a mechanical pump starting system, an electrical pump starting system, a motor and a control system, wherein the pump starting switching system switches over the mechanical pump starting system and the electrical pump starting system, and the power supply system supplies power to the motor through the electrical pump starting system or the mechanical pump starting system which is switched on by the pump starting system; the power supply system comprises a power supply module and a power storage module, when the pump starting switching system switches on the electrical pump starting system, the control system controls the power supply module to supply power to the motor through the electrical pump starting system and supply power to the power storage module, and at the moment, the power storage module stores power; and when the pump starting switching system switches on the mechanical pump starting system, the control system controls the power supply module and the power storage module to supply power to the motor through the mechanical pump starting system, and at the moment, the power storage module discharges power. By the scheme, when electrical pressure reduction pump starting is carried out, redundant energy of the power supply system can be stored, and pump starting is assisted when mechanical full-pressure pump starting is carried out.

Description

Technical field [0001] The present invention relates to the technical field of starting pumps, in particular a integrated electrical and mechanical starting pump device. Background technique [0002] The fire water pump is used to provide fire-fighting water, pressurized by fire water pumps to meet the requirements of water pressure and water in the fire extinguishing. If the water pump is not properly started due to the failure, it will affect the fire rescue, resulting in unnecessary losses . Therefore, the pump device of the fire pump usually has mechanical emergency pump function. [0003] In the prior art, the pump device of the fire pump includes a power supply system, a pump switching system, a mechanical start-up pump system, an electrical setup system, an electric motor and control system, and the control system switches the electrical suction pump system by opening the pump switching system. By the power supply system bucking the motor, the step-down boot pump is achiev...
