Liquid conveying system

Abstract

The invention discloses a liquid conveying system which comprises a liquid storage tank, a high pressure generator, a stator and a rotor, wherein a liquid input opening is formed at the top of the liquid storage tank; the high pressure generator is used for gasifying liquid; a liquid output opening is formed at the bottom of the high pressure generator and a gas outlet is formed at the top of the high pressure generator; the stator is provided with a high pressure cavity and a low pressure cavity which are isolated from each other; the rotor is arranged at an intersection between the high pressure cavity and the low pressure cavity in a rotatable manner; a channel is formed on the rotor; a position difference in a vertical direction exists between an inlet and an outlet of the channel; the inlet and the outlet are alternately positioned in the high pressure cavity or the low pressure cavity with the rotation of the rotor; the bottom and the top of the high pressure cavity are communicated with the bottom and the gas outlet of the high pressure generator respectively; the bottom of the low pressure cavity is communicated with the bottom of the liquid storage tank; and a gas outlet communicated with the liquid storage tank is formed at the top of the low pressure cavity. Through pressuring low pressure liquid to obtain high pressure liquid or steam product, the liquid conveying system achieves the function of liquid conveying; compared with the conventional pump, the liquid conveying system has the advantages that a large amount of precious high-level electric energy can be saved, an energy-saving effect is obvious and the power consumption is low.

Description

technical field [0001] The invention belongs to the field of mechanical equipment, and in particular relates to a 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. According to incomplete statistics, the annual output value of pump products in my country is more than 40 billion yuan, and 20% to 25% of the annual national power generation is consumed on pump products. In recent years, the demand for pumps in chemical industry, petrochemical industry, power station, mine and shipbuilding and other industrial fields has been increasing, which has promoted the development of pump technology. Nowadays, all human beings propose a sustainable development strategy, and the pump products emphasize the requireme...

Problems solved by technology

Because these pumps generally have the problem of negative pressure delivery, the positive displacement pump needs to discharge the air in the pipeline before it can pump the liquid when it is working. waste of electricity

Because there is also the problem of negative pressure transmission, it is easy to cause local air pockets in the pipeline, resulting in mixed transportation of oil and gas, resulting in a decrease in equipment efficiency
