Description

Technical Field

[0001] The utility model relates to the technical field of diaphragm pumps, in particular to a thermal stress and thermal deformation self-adaptive hydraulic end base. Background Art

[0002] In the conventional application conditions of diaphragm pumps, the hydraulic end base is mainly arranged in the diaphragm chamber and the hydraulic pipe, and is mainly used to support and stabilize the relevant components of the hydraulic end, without considering the impact of thermal stress release and thermal deformation.

[0003] However, when the diaphragm pump is used in high temperature conditions (≥200℃), it is necessary not only to consider the support of the hydraulic end and the impact of the unit vibration on it, but also to study the side effects of thermal stress and thermal deformation on it. At this time, the conventional hydraulic end base cannot meet the requirements, and a hydraulic end base with thermal stress and thermal deformation functions is required to play a stabilizing and supporting role. Utility Model Content

[0004] The utility model aims to provide a thermal stress and thermal deformation self-adaptive hydraulic end base to solve the problem that the existing conventional diaphragm pump hydraulic end base cannot meet the thermal stress and thermal deformation requirements under high temperature conditions.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a thermal stress and thermal deformation adaptive hydraulic end base, including a horizontal base and a vertical support, the horizontal base is in the shape of a rectangular frame, a connecting hole is provided at the bottom end of the horizontal base, the vertical support is connected to the upper end of the horizontal base, the vertical support includes a fixed plate, a support plate and a connecting plate, the fixed plate is connected to the horizontal base, the support plate is "bow-shaped", a support section is provided at the bottom of the support plate to connect with the fixed plate, and an introduction angle for fixing the connecting plate is provided at the top of the support plate.

[0006] Preferably, as an improvement, the support plate is an independent single plate structure, and the "bow-shaped" corners are rounded transition.

[0007] Preferably, as an improvement, the middle portion of the support plate is inclined toward the connecting plate.

[0008] Preferably, as an improvement, the horizontal base includes two longitudinal frames arranged side by side, a plurality of transverse frames are arranged side by side between the two longitudinal frames, and a vertical support is provided on each transverse frame.

[0009] Preferably, as an improvement, a leveling plate is connected to the bottom of the horizontal base, and the connecting hole passes through the leveling plate.

[0010] Preferably, as an improvement, the longitudinal frame and the transverse frame are both H-shaped steels, and the horizontal base is provided with a plurality of ribs along the circumferential direction, and the ribs are located between the upper and lower flanges of the H-shaped steel.

[0011] Preferably, as an improvement, a connecting hole is opened on the connecting plate, and its surface is a processed plane.

[0012] The principles and advantages of this solution are: in actual application, the horizontal base is connected to the lower link, and the vertical support is used to support the diaphragm pump feed valve box. The horizontal base ensures the installation level through the leveling plate, is fastened to the foundation bolts through the connection holes, and the structural strength is strengthened by the rib plate. The fixed plate of the vertical support is connected to the horizontal base to provide support. The support plate adopts a "bow-shaped" structure with a certain inclination angle to adapt to thermal deformation. It has an independent single-plate structure and a rounded transition at the corners, which can reduce local stress while releasing thermal stress. Such a hydraulic end base has a high structural strength, can adapt to the thermal stress and thermal deformation of the diaphragm pump under high temperature conditions, and ensure that the hydraulic end of the diaphragm pump works stably and reliably under high temperature conditions.
