Embodiment 1

[0096] Embodiment 1: as figure 1 , the series power water pump includes a gas generator set, a heat pump unit and an electric control system, wherein the fuel generator set includes an engine 1 and a generator 2, wherein the generator 2 has a drive shaft 201 for power output; wherein the water pump includes a water pump motor 3 and Water pump body 32, water pump body 32 adopts double shaft extension structure, one end transmission shaft is connected with water pump motor 3, and the other end is connected with transmission shaft 201 of engine 1 through coupling device 5.

[0097] refer to figure 2 and image 3 They are schematic diagrams of connection and separation of the coupling device 5, respectively.

[0098] refer to Figure 4 , The electronic control system includes an engine control module, an air source heat pump control module, a water pump motor module, a power generation module, an anti-gravity control module, and a transmission control module. Wherein the engi...

Embodiment 2

[0114] The difference from Embodiment 1 is that the water pump motor module uses a frequency-adjustable power supply, which can automatically adjust the speed of the water pump motor 3 according to the load of the water pump.

Embodiment 3

[0116] refer to Figure 15 and Figure 16 , the difference from Embodiment 1 is that the coupling device 5 adopts a flange coupling without a transmission control module, including a driving disc 501, two sets of flexible connecting pieces 502, an intermediate connecting section 503, a driven disc 504, and connecting bolts 505 and nut 506. The driving disk 501, the flexible connecting piece 502, the intermediate connecting section 503 and the driven disk 504 all have a number of through holes through which bolts can pass. One set of flexible connecting pieces 502 are alternately fixed to the driving disk 501 and the intermediate connecting section 503 by bolts 505 and nuts 506; the other set of flexible connecting pieces 502 are alternately fixed to the driven disk 504 and the intermediate connecting section by bolts 505 and nuts 506 503 fixed. When the driving disc 501, the flexible connecting piece 502, the intermediate connecting section 503 and the driven disc 504 are c...

Abstract

The invention discloses a series power water pump. The series power water pump comprises a fuel generator set, a water pump and an electronic control system, wherein the fuel generator set consists ofan engine and a generator; the water pump consists of a water pump motor and a water pump body; transmission shafts which extend outwards are separately arranged at two ends of the generator and thewater pump body; one ends of the transmission shafts of the generator are connected with a transmission shaft of an engine; the other ends of the transmission shafts of the generator are connected with the transmission shafts of the water pump body through connecting shaft devices; and the other ends of the transmission shafts of the water pump body are connected with the water pump motor. The invention further discloses a heat pump system which comprises a gas water pump. The heat pump system comprises one or more water pumps and one or more air source heat pump units, at least one water pumpis the gas water pump, each air source heat pump unit comprises a compressor, a water side heat exchanger, a surface air cooler and a four-way valve, and the water side heat exchanger discharges coldwater or hot water. Electric power and natural gas various running modes are adopted, electric power and natural gas complement each other's advantages, and the energy utilization efficiency is high.

Description

technical field [0001] The invention relates to the field of gas-fired power generation and air conditioning, in particular to a series power water pump and a heat pump system including the series power water pump. Background technique [0002] The central air-conditioning system mainly includes air-conditioning hosts, water pumps and fan coil units at the end. For small and medium-sized central air-conditioning systems, many air-conditioning hosts use air-source heat pump units. Below, there is the problem of surface cooler frosting, low efficiency, and poor effect, especially in the area around the Yangtze River, the prior art generally adopts the addition of electric auxiliary heaters, or directly adopts gas-fired boilers for heating. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a serial dynamic water pump and a heat pump system including the serial dynamic water pump. Complementary advantages are perfectl...
