Detailed Description

It should be noted that, the utility model discloses a technical scheme that each embodiment demonstrates, its technical conception lies in the technical difficulty that each influence factor exists to the life who has overcome among the prior art damping device itself and (frequency conversion constant voltage is automatic) water supply equipment, including but not limited to: in the first aspect, the existing hydraulic shock absorber has poor damping effect and is difficult to maintain a stable damping state; in the second aspect, the operation of the equipment generates great noise, and the vibration quantity of the equipment is increased due to the existence of resonance factors, so that the action frequency of the damping device is indirectly influenced; in the third aspect, in the existing water supply equipment, under the condition that a single water pump cannot meet the flow demand, the single water pump with overlarge system flow is often selected to replace the existing water supply equipment so as to meet the demand on the flow, thus increasing the operation cost, causing the problem of 'dry pumping' at the same time, failing to meet the actual water supply demand, causing the vibration of a water pump group due to the fact that the flow and the pressure of the water pump group cannot meet the preset requirements, indirectly influencing the action frequency of a damping device and increasing the vibration quantity of the whole equipment; in case of frostbite, the water supply equipment is in operation with diseases, the overall balance of the equipment is influenced, so that the equipment vibrates relatively, normal water supply is influenced due to the existence of resonance factors, the user investment and the operation cost are increased, and the overall vibration of the equipment is aggravated. The following further explains how the technical solution of the present invention can overcome the technical difficulties in the above aspects in implementation, through a plurality of embodiments and modified examples.

It is easy to understand that the existing hydraulic shock absorber as a shock absorption damping device has poor damping effect, cannot keep a state for damping work, and is particularly characterized in that the method for changing the mass by changing the volume of liquid has a complex structure, a plurality of auxiliary devices and inconvenient installation, and for example, most methods for changing the rigidity adopt a stepping motor to drive a lead screw as an actuator, the lead screw is worn in vibration, so that the precision is reduced, and the hydraulic shock absorber has certain delay; the shock absorber made of the intelligent material is high in cost and high in price, and is not suitable for popularization. Meanwhile, the operation of the water supply equipment generates great noise, and the vibration quantity of the equipment is increased due to the existence of abnormal severe vibration factors, so that the action frequency of the damping device is indirectly influenced. These factors of influence mainly include: when a single water pump cannot meet the flow demand, the conventional water supply equipment often selects the single water pump with overlarge system flow to replace the single water pump so as to meet the flow demand, so that the operation cost is increased, meanwhile, the problem of 'dry pumping' is caused, the actual water supply demand cannot be met, the flow and the pressure of a water pump group cannot meet the preset requirements, the water pump group vibrates, and the integral vibration of the equipment is increased; and once the equipment is frostbitten and is operated with diseases, the overall balance degree of the equipment is influenced, so that the equipment has larger vibration, and the overall vibration of the equipment is also aggravated.

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
