Description

A thermal stress and thermal deformation adaptive fluid end base TECHNICAL FIELD

[0001] The present application relates to the technical field of diaphragm pumps, in particular to a thermal stress and thermal deformation adaptive fluid end base. BACKGROUND

[0002] In the conventional application conditions of the diaphragm pump, the fluid end base is mainly arranged at the diaphragm chamber and the fluid pipe, and is mainly used to support and stabilize the related parts of the fluid end, without considering the influence of thermal stress release and thermal deformation.

[0003] However, when the diaphragm pump is applied in the high-temperature working condition (≥200℃), not only the support of the fluid end and the influence of the unit vibration need to be considered, but also the side effects of thermal stress and thermal deformation need to be studied. At this time, the conventional fluid end base cannot meet the requirements, and a fluid end base with thermal stress and thermal deformation function needs to be used to play a stabilizing and supporting role. SUMMARY

[0004] The present application aims to provide a thermal stress and thermal deformation adaptive fluid end base to solve the problem that the conventional diaphragm pump fluid end base cannot meet the requirements of thermal stress and thermal deformation in high-temperature working conditions.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a thermal stress and thermal deformation adaptive fluid end base, comprising a horizontal base and a vertical support, the horizontal base is in the shape of a rectangular frame, the horizontal base is provided with a connecting hole at the bottom end, the vertical support is connected to the upper end of the horizontal base, the vertical support comprises a fixed plate, a support plate and a connecting plate, the fixed plate is connected to the horizontal base, the support plate is in the shape of an arc, the bottom of the support plate is provided with a support section connected to the fixed plate, and the top of the support plate is provided with a lead-in angle of the fixed connecting plate.

[0006] Preferably, as an improvement, the support plate is an independent single plate structure, and the corners of the arc are transitioned by rounded corners.

[0007] Preferably, as an improvement, the middle part of the support plate is inclinedly arranged towards the connecting plate.

[0008] Preferably, as an improvement, the horizontal base comprises two longitudinal skeletons arranged side by side, a plurality of transverse skeletons are arranged side by side between the two longitudinal skeletons, and each transverse skeleton is provided with a vertical support.

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

[0010] Preferably, as an improvement, the longitudinal skeleton and the transverse skeleton are both H-shaped steel, and the horizontal base is provided with a plurality of rib plates circumferentially, and the rib plates are located between the upper and lower flanges of the H-shaped steel.

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

[0012] The principle and advantages of the present scheme are as follows: in actual application, the horizontal base is connected with the low-level link, and the vertical support is used for supporting the diaphragm pump feed valve box. The horizontal base is guaranteed to be installed horizontally through the leveling plate, is fastened through the connecting hole and the foundation bolt, and the structural strength is reinforced through the rib plate. The fixed plate of the vertical support is connected with the horizontal base to provide support, the support plate adopts an “arch” structure with a certain inclination angle to adapt to thermal deformation, the independent single plate structure is adopted, and the corners are transitioned through rounded corners to reduce local stress and release thermal stress. Such a fluid end base has high structural strength, can adapt to thermal stress and thermal deformation of the diaphragm pump under high-temperature working conditions, and guarantees that the fluid end of the diaphragm pump works stably and reliably under high-temperature working conditions.
