Problems solved by technology

However, the application of DC water pumps in central gas water heaters has the following problems: 1) Due to the high speed of DC water pumps, the main body of the gas water heater is driven to vibrate to generate relatively large vibration noise
2) When the DC water pump is running at high speed during work, the high-speed water flow will collide with the water inlet pipe of the heat exchanger of the gas water heater and cause a large water flow noise

Abstract

The invention discloses a direct-current water pump installation structure of a central gas water heater. A direct-current water pump is connected with the central gas water heater through a water pump supporting plate. The structure is characterized in that an ethylene propylene diene monomer rubber pad is arranged between the water pump supporting plate and the central gas water heater, the water inlet end of the direct-current water pump is connected with a water inlet pipe of the central gas water heater through a first hose, and the water outlet end of the direct-current water pump is connected with a heat exchanger of the central gas water heater through a second hose. According to the structure, rigid connection between the direct-current water pump and the central gas water heateris avoided, vibration of a direct-current water pump body is buffered by the ethylene propylene diene monomer rubber pad, vibration of a water inlet and a water outlet of the direct-current water pumpis buffered by the braided hoses, the portion between a bottom cover of the direct-current water pump and the water pump supporting plate is buffered by the ethylene propylene diene monomer rubber pad, and noise generated in the working process of the direct-current water pump is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of fluid heaters, in particular to a central gas water heater DC water pump installation structure. Background technique [0002] Central gas water heaters generally use water pumps as the circulating power, and DC water pumps are favored because of their high speed, sufficient power, and large circulating water flow. However, the application of the DC water pump in the central gas water heater has the following problems: 1) Due to the high speed of the DC water pump, the main body of the gas water heater is driven to vibrate to generate relatively large vibration noise. 2) When the DC water pump is running at a high speed during work, the water flow is thrown out at high speed and collides with the water inlet pipe of the heat exchanger of the gas water heater, causing a large water flow noise. Contents of the invention [0003] Aiming at the problems existing in the prior art, the object of the present ...
