Underwater specialized low-temperature resistant and high-pressure resistant intelligent self-suction type injection pump

Abstract

The invention discloses an underwater specialized low-temperature resistant and high-pressure resistant intelligent self-suction type injection pump, belonging to the technical field of water pumps. The underwater specialized low-temperature resistant and high-pressure resistant intelligent self-suction type injection pump comprises a shell and a motor provided with double shafts and connected to the shell, wherein the shell is internally provided with a water suction cavity which is internally provided with an impeller component; an injection orifice is arranged at the front end of the shell; a water inlet is formed at the upper end of the shell; an output shaft at one end of the motor is connected to the impeller component; an end cover is connected at the other end of the motor; a sealed inner cavity is formed between the end cover and the motor; the inner cavity is internally provided with a radiator; a controller used for controlling the motor and the radiator is arranged at the upper part of the motor; electricity can be supplied to the controller through a DC (Direct Current) power source or a battery; mechanical seal is arranged between the motor and the shell; the shell and the outer shell of the motor are made of low-temperature steel and are molded through integral casting. The underwater specialized low-temperature resistant and high-pressure resistant intelligent self-suction type injection pump has a simple and rational structure design; and compared with the traditional injection pump, the underwater specialized low-temperature resistant and high-pressure resistant intelligent self-suction type injection pump can adapt to low-temperature and high-pressure malicious environments, can guarantee normal operation of the work, and prolongs the service life.

Description

technical field [0001] The invention belongs to the technical field of water pumps, and in particular relates to an intelligent self-priming jet pump dedicated to underwater with low temperature and high pressure resistance. Background technique [0002] Water is the root of human existence, and water is the lifeblood of agriculture. my country is a country with many people, little land, water shortage and frequent natural disasters. Agricultural irrigation water accounts for more than 80% of the country's total water use, while China's total water resources account for about 7% of the global total, and the per capita water resources are only a quarter of the world's average level. It is listed by the United Nations as 13 water-deficient one of the countries. China needs to use 7% of the world's water to maintain the production and life of 22% of the population. Among the 517 cities in the country, more than 300 cities lack water. my country is also a large agricultural c...

Problems solved by technology

However, the existing self-priming jet pump has a single drive mode, generally a separate electric or belt type, and a separate working mode. As long as the power is cut off or the pulley is damaged, the pump cannot be used normally, which will affect the work.

And the electric jet pump cannot be adjusted due to the current, w
