Problems solved by technology

The operating conditions of the plunger pump are complex and changeable. The current general-purpose plunger pump noise reduction method is often designed for a specific working condition, and the filtering range achieved is very limited. After the plunger pump deviates from the operating condition, the noise reduction The effect will be greatly reduced

Embodiment Construction

[0024] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] Such as Figure 1~3 As shown, a noise reduction device for a plunger pump mainly includes a metal bellows 1 and a valve plate 3 as a filter chamber. The filter cavity is detachably connected to the distribution plate 3, and can be connected by plugging, threading or other suitable connection methods.

[0026] The metal bellows 1 is used as a filter cavity to pre-compress the hydraulic oil in the plunger pump when the plunger cavity transitions from the oil suction area to the oil discharge area, so as to reduce the pressure ...

Abstract

The invention belongs to the field of fluid drive and control, and particularly relates to a noise reduction method for a plunger pump and a noise reduction device thereof. A filtering cavity is connected with a valve plate, the filtering cavity has a filtering function utilized to filter hydraulic oil in a plunger cavity, and after the plunger cavity is contacted with the filtering cavity, the pressure fluctuation in the plunger cavity can be reduced; oil fluid in the plunger cavity is pressurized through a pressure boost cavity, a differential pressure between the plunger cavity and a plunger pump eduction oil cavity can be reduced so as to reduce the outlet flow fluctuation of a fluid pump. A metal corrugated pipe is connected with the valve plate through damping pinholes to form an RCfilter, the metal corrugated pipe can be dismantled and has different specifications, the damping pinholes can be adjusted, and the filter range can be adjusted by changing parameters of the metal corrugated pipe and damping pinholes. According to the plunger pump working in different conditions, the parameters can be adjusted to achieve a best noise reduction effect.

Description

technical field [0001] The invention belongs to the field of fluid transmission and control, and in particular relates to a noise reduction method and a noise reduction device for a plunger pump. Background technique [0002] Piston pumps are widely used in industry due to their advantages of compact structure and high efficiency. However, it is noisy, and the problem of noise reduction needs to be solved urgently. The main causes of noise in the plunger pump are: due to the unequal speed of the plunger's reciprocating movement, the change in the number of oil discharge areas, and the flow pulsation caused by the pressurization and decompression effects of the plunger cavity during high and low pressure transitions, It forms a pressure pulsation under the influence of the load, and the pressure pulsation is applied to the plunger pump assembly, causing the components in the plunger pump to vibrate and generate noise. [0003] The traditional filtering method utilizes the c...
