Device and system for liquid transformation and conveying

Abstract

The invention provides a device and system for liquid transformation and conveying. The device comprises a pressure transmitting device, a liquid inlet check valve and a liquid outlet check valve and a power driving device. The pressure transmitting device comprises a cylinder tube and a plunger located in the cylinder tube, the plunder can axially moves inside the cylinder tube along the cylinder tube, and a liquid inlet hole and a liquid outlet hole are formed in the tube; the liquid inlet check valve and the liquid outlet check valve are independent of the pressure transmitting device and are connected to the liquid inlet hole and the liquid outlet hole through pipelines; the power driving device is arranged at the other end of the cylinder tube by being isolated from the cylinder tube, the power driving device comprises a transmitting push-pull rod capable of making upward to-and-fro movement on the cylinder tube, and the transmitting push-pull rod is coupled with the plunder through a coupling so as to make the power driving device provide power for the to-and-fro movement of the plunger via the transmitting push-pull rod. The system for the liquid transformation and conveying comprises a large amount of the equipment.

Description

technical field [0001] The invention relates to equipment and a system for variable pressure transmission of liquids, in particular to equipment and a system for variable pressure transmission of corrosive liquids. Background technique [0002] In engineering applications, it often involves the pressure increase and transmission of liquids in pipelines, referred to as pressure transmission devices. In practical applications, various forms of "pumps" are usually used as power sources to realize pressure transmission. [0003] The "pump" is actually an integrated electromechanical system with multiple components integrated together. Especially for the plunger pump, the motor, crankshaft connecting rod, piston, cylinder, check valve and other components are integrated on one cylinder, and the solution to be delivered is directly affected by the high-speed running components (blades, gears, plungers, etc.) ) to drive the lifting pressure and output it from the pump body. There...

AI Technical Summary

Problems solved by technology

Especially for plunger pumps, motors, crankshaft connecting rods, pistons, cylinders, check valves and other components are all integrated on one cylinder, requiring professional and technical personnel from the manufacturer to have the skills to disassemble, replace parts and install and debug. ability, but as a pump application unit, it does not have such technical strength. Therefore, once a failure occurs, the whole machine can only be replaced, which greatly increases the operation and maintenance cost of the equipment.

[0008] Therefore, the highly integrated characteristics of the pump become a disadvantage in the strong corrosion application environment
