Intelligent miniature constant-flow low-pulse high-temperature plunger pump

Abstract

The invention relates to an intelligent miniature constant-flow low-pulse high-temperature plunger pump which comprises an intelligent control motor, an eccentric transmission rotor device used for being connected with an output shaft of a drive motor, a double-direction plunger, a pump body, a pump cover, a sealing part, an oil input one-way valve, an oil output one-way valve, a water input pipeopening, a pulse eliminating device and a pressure heating device. The plunger pump is compact in structure, high-pressure medium pulse can be effectively reduced, the chance for raising the medium temperature is increased, the practical effect is good, the pump use efficiency is improved, and operation time is prolonged greatly. According to the plunger pump, by means of cooperation with the pumpbody and adjustment of the pulse eliminating device, forced pressurizing and circulating are achieved, thus, medium flow is stable, medium viscosity is reduced, the atomizing efficiency is improved,the actual use pressure is reduced, motor power dissipation is reduced, and therefore electrical energy consumption is reduced.

Problems solved by technology

[0002] 1. The existing plunger pump has a high output pressure, and its structure generally adopts a driving structure such as a connecting rod type, a gear type, and a cam type. It has a large volume, a complex structure, and a large flow rate. For combustion engine pumps, there is an urgent need for high-pressure low-flow intelligent control , to apply to the chemical characteristics of biomass fuel: organic fuels such as alcohol-based liquid fuels, aromatic liquid fuels, lipid liquid fuels, benzene liquid fuels, biomass energy and other clean energy fuels, some fuels have corrosion, dissolution, reaction For small burners, small flow and high pressure are required, and continuous high-pressure oil supply to the atomized burner is required. For example, the combustion pump used in a 50,000 kcal boiler requires a pressure of 8 kg and a flow rate of 6-8 liters / hour Left and right; the flow rate of existing plunger pumps cannot be achieved and the volume of the pump will be large, and the flow rate will be too large. It is not suitable to make a pump with a small flow rate and the efficiency is too low; it is not suitable for organic clean fuels that are volatile, easy to vaporize, low density and low lubricity. In particular, there is no solution for easy vaporization

[0003] 2. Since the existing biomass oil itself has a certain viscosity, especially in winter when the ambient temperature is low, its viscosity is higher. If it is atomized and burned, it needs higher pressure, which also causes waste of electric energy. Only by providing biomass The temperature of the oil can greatly reduce its viscosity, but the existing plunger pump cannot provide the function of heating the oil, and before that, there is no burner pump that can completely and reliably meet the needs of all fuel media in China. There is an urgent need for integrated pumps, Special pump for motor and intelligent control of burner with constant pressure and heating function

[0004] 3. Existing UAVs spray pesticides, using gear pumps, vortex pumps and ordinary plunger pumps, etc., due to their large size and heavy weight, they should be limited and cannot be promoted on a large scale. The market for UAVs spraying pesticides should be urgently needed A small volume and light weight, with high pressure constant pressure pump
