Description

Technical Field

[0001] The invention relates to the field of water pump transmission, and in particular to a water pump direct-connection transmission system. Background Art

[0002] A water pump is a machine that transports liquids or pressurizes liquids. The water pump transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals. It can also transport liquids, gas mixtures and liquids containing suspended solids. According to different working principles, it can be divided into volumetric water pumps, vane pumps and other types. The volumetric pump uses the change in the volume of its working room to transfer energy; the vane pump uses the interaction between the rotating blades and water to transfer energy. There are centrifugal pumps, axial flow pumps and mixed flow pumps. The photovoltaic water pump system effectively saves water and electricity, reduces the input of traditional energy, and achieves zero carbon dioxide emissions.

[0003] The rated power of the water pump is 185kw, and the rated speed is 470rpm, so an acceleration and deceleration device is required. The water pump inlet flange is horizontally connected to the pipeline flange, so the overall water pump can be freely deformed along the inlet and outlet axes. At the same time, the deformation during operation is 10mm. Since the belt drive is a flexible drive, a belt drive solution is adopted, but this transmission method has the following disadvantages: the seven belts are of different lengths, resulting in uneven force on each belt, which affects the life of the belt. In addition, since the tensioning force required for the belt drive is very large, the shaft and bearings are under great force, which affects the service life; the narrow V-belt has an efficiency of about 92% due to uneven force and elastic sliding, which is more energy-consuming; the belt drive will generate static electricity due to friction, and there is a certain risk when used in chemical plants; in order to reduce the size of the large pulley, a 6-pole motor is selected, which is more expensive than a 4-pole motor.

[0018] Compared with the prior art, the present invention provides a water pump direct-connection transmission system, which has the following beneficial effects:

[0019] 1. The water pump direct-connected transmission system has a horizontal water pump inlet pipe connected to the water pump body flange, so the whole water pump body can be freely deformed along the axial directions of the water inlet and the water outlet, thereby eliminating the need to install an expansion joint. Since the water pump body is directly connected, the rotor is not subject to additional bending moments and its life span is greatly increased, which greatly improves the transmission efficiency of the planetary reducer and can effectively reduce the waste of electricity.

[0020] 2. The water pump direct-connected transmission system can supply lubricating oil to the bearing seat through the oil tank and oil groove. By starting the hydraulic push rod, the push plate can squeeze the lubricating oil in the inner cavity of the bearing seat to the middle of the inner cavity of the bearing seat, so that the lubricating oil can be squeezed into the planetary reducer through the oil outlet hole. In this way, the planetary reducer installed at the bearing seat can be lubricated, which can effectively improve the service life of the planetary reducer and prevent it from being damaged due to severe wear.

[0021] 3. The water pump direct-connected transmission system can achieve a shock-absorbing effect when the water pump body is working through the provided damper, effectively reduce the vibration and noise generated when the water pump body is working, and improve the comfort of use. The provided rotating block can move with the movement of the water pump body, and the provided movable column can move with the movement of the rotating block. At this time, the movable column will squeeze the spring to achieve a buffering effect. When the water pump body is working, it can be further protected to prevent the structural damage caused by excessive rotation speed. BRIEF DESCRIPTION OF THE DRAWINGS
