Description

Adjustable double-suction centrifugal pump Technical Field The utility model relates to a double suction pump, in particular to an adjustable double suction centrifugal pump. Background The double suction pump is an important form of centrifugal pump, and is widely applied in engineering due to the characteristics of high lift, large flow and the like. The horizontal double-suction centrifugal pump must regulate and control the pump shaft to be in a horizontal state during installation, the core aim is to ensure accurate centering of the pump shaft and a motor shaft, if the pump body is inclined, severe vibration, abnormal abrasion of a bearing, mechanical sealing or filling sealing failure (leakage) are caused, even serious consequences such as shaft breakage are caused, and stable operation and service life of the pump are seriously affected. For a small double-suction centrifugal pump with the weight not exceeding 150 kg, in the prior art, a plurality of leveling feet are usually arranged at the bottom of the centrifugal pump, the centrifugal pump can keep the pump shaft horizontal on uneven ground by adjusting the heights of the feet, however, when the centrifugal pump in a non-working state is conveyed in the vertical direction, as the leveling feet firstly contact the ground, if a multi-person cooperative conveying mode is adopted, a conveying person needs to synchronously reduce the height of the pump through actions such as bending, bending and the like, in the process, the coordination of the actions of the human body and the accuracy of force control are obviously limited (such as sight is blocked, muscle force is insufficient, action is asynchronous and the like), the speed of the lowering of the pump body is difficult to be accurately controlled so as to realize slow and uniform landing, the leveling feet are extremely easy to strike the ground at a higher speed and bear impact load, threads of the leveling feet are worn quickly, even sliding wires appear, the service life of the feet is greatly shortened, and the labor force required to be used for leveling is larger when the bending and the waist of the conveying person is higher. Disclosure of Invention The utility model aims to provide an adjustable double-suction centrifugal pump, which aims to solve the problems in the background art: When the centrifugal pump in a non-working state is conveyed in the vertical direction, the leveling foot is extremely easy to strike the ground at a higher speed and bear impact load, so that threads of the leveling foot are quickly worn or even slide, and the service life of the leveling foot is greatly shortened. In order to solve the problems, the utility model aims to provide an adjustable double-suction centrifugal pump which comprises a centrifugal pump main body, wherein a mounting base is arranged at the bottom of the centrifugal pump main body, the mounting base comprises a top plate horizontally fixed at the bottom of the centrifugal pump main body through a bracket, a bottom plate is arranged below the top plate, a distance adjusting mechanism for adjusting the distance between the bottom plate and the top plate is arranged between the bottom plate and the top plate, support columns are vertically fixed at the positions, close to four corners, of the lower side wall of the top plate, of the support columns are in threaded connection with leveling feet, through grooves are formed in the positions, corresponding to each support column, of the bottom plate, when the centrifugal pump main body is in a working state, the distance adjusting mechanism drives the bottom plate to be close to the top plate, each leveling foot passes through the corresponding through groove and moves to the lower part of the bottom plate, and when the centrifugal pump main body is in a non-working state, the distance adjusting mechanism drives the bottom plate to be far away from the top plate, and each leveling foot is located in a space between the top plate and the bottom plate. As a further improvement of the technical scheme, the distance adjusting mechanism comprises two crossed hinge frames symmetrically arranged between the top plate and the bottom plate, two ends of one side of each crossed hinge frame are hinged to the edge of one side of the top plate and the edge of one side of the bottom plate, which are close to each other, a linkage rod is horizontally fixed between the ends of the other sides of the two crossed hinge frames, guide frames are sleeved at positions, which are close to the two ends, of the linkage rod in a sliding mode, the two guide frames positioned above are horizontally fixed on the lower side wall of the top plate, and the two guide frames positioned below are horizontally fixed on the upper side wall of the bottom plate. As a further improvement of the technical scheme, the distance adjusting mechanism further comprises a moving block fixedly arranged at the middle position of the lower lin
