Embodiment Construction

[0035] Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] see figure 1 , figure 2 , image 3 , Figure 4 .

[0037] The present invention is a positive displacement liquid pressure energy recovery device, which includes an end cover 1, a pump body 2, a double-acting pressurized cylinder piston 3, a double-acted pressurized cylinder body 4, a bearing 5, a flow distribution shaft 6, and a speed-regulating motor 7.

[0038] The bearing 5 is installed on the pump body 2 to support the distribution shaft 6, and the distribution shaft 6 is installed in the center hole of the pump body 2 in motion, and the two end caps 1 located at both ends of the distribution shaft 6 connect the distribution shaft 6 Fixed, restricting its axial movement.

[0039] The speed regulating motor 7 is fixed on the end cover 1 at one end with screws, and the output shaft of the speed regulating motor 7 is connected wit...

Abstract

The invention belongs to the field of liquid pressure technical equipment, and in particular relates to a positive displacement liquid pressure energy recovery device by which liquid with excessive pressure is required to be used or discharged under reduced pressure in the industrial production process. The device comprises end covers, a pump body, a double-acting pressurization tank piston, a double-acting pressurization tank body, a bearing, a flow distribution shaft and a speed regulation motor, wherein the bearing is arranged on the pump body and is used for supporting the flow distribution shaft; the flow distribution shaft is arranged in the central hole of the pump body in a movable fit way; the two end covers are used for fixing the flow distribution shaft and limiting the movement of the flow distribution shaft in the axial direction; the speed regulation motor is fixed on one end cover at one end through a screw; and an output shaft of the speed regulation motor is connected with the flow distribution shaft through a key. By the device, energy emitted by the liquid with the excessive pressure in the industrial production process can be effectively used and recycled, and production cost can be reduced; and the device has a wide application range.

Description

technical field [0001] The invention belongs to the field of hydraulic technology equipment, and in particular relates to a positive displacement liquid pressure energy recovery device used for decompression of excess pressure liquid in the industrial production process. Background technique [0002] In the process of industrial production, the excess pressure liquid in many processes is decompressed to the required low pressure through the pressure reducing valve, or the waste liquid discharged from the process still has a relatively high pressure. During the process of decompression and discharge, a large amount of The pressure of the liquid can be converted into heat and dissipated in the environment. Recovering this energy saves considerable annual costs. [0003] At present, liquid pressure energy recovery devices are divided into two categories: hydraulic turbine and positive displacement in terms of working principle. The first category is hydraulic turbine, also kn...
