Description

Technical Field

[0001] The utility model relates to a feed pump and its technical field, and particularly to a single-cylinder double-feed pump body structure with stable flow and vibration reduction. Background Technique

[0002] As Figure 1 shown, the existing single-cylinder double-feed pump body pipeline assembly is composed of an over-flow pipe assembly on the power cylinder, a confluence pipeline, a right pipeline head component, a right pipeline tee component, a pump feed pipe component, and a pump discharge pipe component; when the equipment is running, due to the small over-flow diameter of the over-flow pipe assembly on the power cylinder, the over-flow velocity is relatively fast, which affects the flow rate, and the actual flow rate of this structure cannot reach the designed flow rate value; in addition, due to the structural influence, the length of the over-flow pipe assembly on the power cylinder extending out is relatively long, and the suspended rigidity is poor, and vibration will occur during the operation of the equipment, and the vibration will cause the pipeline weld to crack, affecting the use of the equipment. Content of the Utility Model

[0003] The purpose of the utility model is to provide a single-cylinder double-feed pump body structure that can avoid fast fluid velocity, ensure stable flow and achieve vibration reduction in view of the deficiencies in the above background technique.

[0004] To achieve the above purpose, a single-cylinder double-feed pump body structure with stable flow and vibration reduction of the utility model adopts the following technical solutions:

[0005] A single-cylinder double-feed pump body structure with stable flow and vibration reduction includes a working cylinder, one end of the working cylinder is provided with a power cylinder, and the other end is connected to a communicating pipe through an over-flow pipe. The upper end of the communicating pipe is connected to the pump discharge pipe through a discharge check valve, and the side end is connected to the pump feed pipe through a feed check valve. On the upper part of the side of the working cylinder away from the over-flow pipe, there is a second over-flow pipe, and the second over-flow pipe is connected to a second communicating pipe. The upper end of the second communicating pipe is connected to the pump discharge pipe through a second discharge check valve, and the side end is connected to the pump feed pipe through a second feed check valve.

[0006] A further improvement of the single-cylinder double-feed pump body structure with stable flow and vibration reduction of the utility model is that the second over-flow pipe is a straight pipe and is arranged vertically, and the over-flow pipe is a bent pipe, and the upper connecting surface of the over-flow pipe is arranged horizontally.

[0007] A further improvement of the single-cylinder double-feed pump body structure with stable flow and vibration reduction of the utility model is that the working cylinder and the power cylinder are installed and connected to the base frame through a connecting frame.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] 1. The present utility model cancels the opening of the overflow pipeline on the power cylinder and directly opens the overflow pipeline on the working cylinder. The caliber of the overflow pipeline at the head is upward and on the same center line as the working cylinder; the discharge one-way valve is also installed on the same center line as the working cylinder; the feeding and discharging pipelines are respectively arranged on both sides of the working cylinder, so that the force on the pump body structure is uniform.

[0010] The overflow pipe diameter of the present utility model is one specification larger than the original overflow pipe diameter, which avoids the phenomenon of fast fluid flow rate, and the pump body pipeline structure is arranged from the center of the equipment to both sides of the equipment, avoiding the phenomenon of vibration when the equipment is running.
