The pressure-adjustable plunger pump and energy recovery all-in-one machine comprises a plunger pump and a plunger motor which are connected with each other, the plunger pump generates high pressure, the plunger motor recovers energy, and the pressure-adjustable plunger pump and energy recovery all-in-one machine comprises a pump flange, a pump front end cover, a pump shell, a motor front end cover, a motor shell and a motor rear end cover which are sequentially connected from right to left. The right side of the coupler is connected with a pump shaft, and the left side of the coupler is connected with a motor shaft; a motor swash plate is arranged between the motor return plate and the motor rear end cover, the bottom of the motor swash plate is in spherical contact with the inner surface of the motor rear end cover, an axial bolt hole is formed in the bottom of the motor swash plate, an axial bolt is inserted into the axial bolt hole from the outer side of the motor rear end cover, and the axial bolt is moved up and down in the radial direction. And the motor swash plate rotates on the inner surface of the motor rear end cover, so that the inclination angle of the motor swash plate is adjusted. The pressure of the device can be regulated and controlled, the device can be suitable for raw water with various salinity and reverse osmosis membranes with various configurations, and the service life of the reverse osmosis membranes is prolonged.
Description
technical field [0001] The application belongs to the technical field of seawater desalination, and more specifically, relates to an integrated machine of a plunger pump with adjustable pressure and energy recovery. Background technique [0002] In today's increasingly tense energy environment, energy recovery is an important measure to improve the utilization rate of existing energy. In the membrane reverse osmosis desalination system, the high-pressure pump and the energy recovery device are the two most important components. The plunger pump and the energy recovery machine effectively integrate the two independent equipment of the high-pressure pump and the energy recovery device, optimizing the system composition. However, the pressure of the conventional plunger pump and energy recovery integrated machine cannot be adjusted at a certain speed. The pressure required for raw water with different salinity is different, and the selection of reverse osmosis membrane will a...
