The invention discloses a liquid conveying system with a single sealing surface. The liquid conveying system comprises a liquid storage tank, a high pressure generator, a stator and a rotor, wherein the liquid storage tank is provided with a liquid import port, a gas inlet and a liquid outlet, the high pressure generator is provided with a liquid inlet and a gas outlet, the stator is provided with a low pressure gas outlet, a low pressure liquid inlet, a high pressure gas inlet and a high pressure liquid outlet which are isolated from one another, the rotor is rotatably arranged in the stator and is provided with through passages, along with the rotation of the rotor, passage inlets and passage outlets are intermittently, simultaneously and respectively communicated with the high pressure gas inlet and the high pressure liquid outlet or simultaneously and respectively communicated with the low pressure liquid inlet and the low pressure gas outlet, the high pressure gas inlet is communicated with the gas outlet, the high pressure liquid outlet is communicated with the liquid inlet, the low pressure gas outlet is communicated with the gas inlet, and the low pressure liquid inlet is communicated with the liquid outlet. The conveying system can change low pressure liquid into high pressure liquid for conveying with only a little energy, has low requirement on equipment installation, is small in end face leakage amount and is relatively high in efficiency.
Description
technical field [0001] The invention belongs to the field of mechanical equipment, and in particular relates to a single sealing surface liquid conveying system. Background technique [0002] Pumps are widely used general-purpose mechanical products, widely used in industrial and agricultural fields such as thermal power generation, nuclear power, oil exploration, petrochemical industry, urban water supply, water conservancy projects, and farmland irrigation. A pump is a machine that transports or pressurizes a liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. The pump is mainly used to transport liquids such as water, oil, acid and alkali liquid, emulsion, suspoemulsion and liquid metal, and can also transport liquid, gas mixture and liquid containing suspended solids. [0003] According to incomplete statistics, the annual output value of pump products in my country is more than 40 b...
