Description

technical field [0001] The invention relates to the field of self-priming pumps, in particular to a non-leakage, anti-clogging, oil-cooled circulation type high-efficiency synchronous intelligent self-priming pump. Background technique [0002] Self-priming pumps refer to pumps that can work without water diversion before the pump is started, and are widely used in steel, chemical, petroleum, electric power, metallurgy, environmental protection, sewage treatment, pharmaceuticals, tap water and other fields. When the ordinary water pump sucks water from the lower tank, a bottom valve is installed at the bottom of the suction pipeline, and the entire suction pipeline must be filled with water before starting. However, the bottom valve often breaks down due to inclusion of sundries or lax closure itself. These failures are absolutely unacceptable under many working conditions such as fire protection, automatic water supply, and domestic sewage. Even under permissible working co...

Problems solved by technology

When the self-priming pump transports slurry, which is prone to freezing, salt formation or material medium that needs to be kept warm, after the first self-priming stop and during the start-up operation, the material will freeze and solidify in the liquid storage chamber of the pump cavity, and the slurry will block the liquid storage chamber Therefore, it is difficult for ordinary vertical self-priming pumps to start and run smoothly in the cold season in the north and in the work of pouring slurry.

Especially when the self-priming pump transports bulk materials, due to the large volume of the material, it is easy to cause blockage of the pump cavity and impeller flow channel, so that the self-priming pump cannot work normally.

Conventional non-sealed self-control self-priming pumps and long-axis submerged pumps, mixed flow pumps, submersible pumps, pipeline centrifugal pumps, slurry pumps and other products in the market, in the transportation of slurry, easy to crystallize, easy to freeze, and back-flow installations due to slurry Medium material density, high backflow pressure, low work efficiency, easy corrosion, high operating cost, frequent maintenance, serious seal leakage, poor sealing performance, labor and time-consuming, many wearing parts, short service life, etc. in operation and user maintenance many shortcomings

[0004] On the basis of many years of research and development, the inventor, according to the special working conditions, installation forms and media such as large slurry ratio, plateau high pressure, large climate temperature difference and reverse irrigation type installation; combined with the market conventional non-sealed self-control self-priming pump and Submerged pumps, mixed-flow pumps, submersible pumps, pipeline centrifugal pumps, slurry pumps and other products, in the transportation of slurry, easy to crystallize, easy to freeze, and reverse-flow installation, because of the medium density of the slurry and the high pressure of reverse flow, it is difficult for operation and users. Low work efficiency, easy to corrode, high operating cost, frequent maintenance, poor sealing performance, labor and time-consuming, many wearing parts, short service life and other problems existing in maintenance have been fully investigated and researched, and independent innovation has been developed.
