Abstract
The utility model discloses a balanced energy saver of an elevator. Fluid-power motors are connected in series on the output shaft of the power motor of an elevator, the working medium liquid input end and the working medium liquid output end of the fluid-power motor are respectively connected with a working medium liquid reservoir, the working medium liquid reservoir of the input end is arranged above the elevator, and the working medium liquid reservoir of the output end is arranged below the elevator; the working medium liquid input end and the working medium liquid output end are respectively provided with a solenoid valve, and the electrical appliance control part of the elevator is respectively connected with two solenoid valves. The fluid-power motors are used for converting elevator lowering potential energy into the working medium liquid potential energy of the fluid-power motors; when the elevator rises, the fluid-power motors use potential energy stored in the working medium liquid to convert into elevator rising potential energy to replace parts of fluid-power motor energy consumption, thus achieving the purpose of saving energy.
Description
Technical field
The utility model belongs to energy-saving device of elevator, particularly a kind of balance energy-saving apparatus of elevator.
Background technology
Motor load is big when travelling in the elevator operation often now.And under when travelling noon and personnel's by gravity motor load very little, gravitional force in braking procedure with the form consumption of friction drag and friction heat.Gravitional force has wasted.If gravitional force can be recycled, both can save a large amount of energy, can reduce the peak value of electric current in the circuit again,

The utility model effect is:
The potential energy that utilizes fluid power motor that elevator is descended changes into the potential energy of fluid power motor working medium liquid, and when elevator rose, the potential energy that the fluid power motor utilization is stored in working medium liquid changed into elevator rising kinetic energy, substitutes the energy consumption of a part of power motor.Reach energy-conservation purpose.
Description of drawings
Fig. 1 is a kind of structural representation of balance energy-saving apparatus of elevator
The specific embodiment
The balance energy-saving apparatus of a kind of elevator as shown in Figure 1, series connection fluid power motor 2 on the output shaft of the power motor 1 of elevator, the input end of fluid power motor working medium liquid and mouth respectively are connected the fluid reservoir of a working medium liquid, the fluid reservoir 4 that the fluid reservoir 3 of input end working medium liquid is arranged on the top mouth working medium liquid of elevator is arranged on the below of elevator, the input end of working medium liquid and mouth respectively are provided with electromagnetic valve 5, and the electrical control part of elevator is connecting two electromagnetic valves.
The a plurality of fluid power motores of series connection on the output shaft of the power motor of elevator, the input end of each fluid power motor working medium liquid and mouth respectively are connected the fluid reservoir of a working medium liquid, the fluid reservoir of input end working medium liquid is arranged on the top of elevator, the fluid reservoir of mouth working medium liquid is arranged on the below of elevator, the input end and the mouth of each fluid power motor working medium liquid respectively are provided with electromagnetic valve, and the electrical control part of elevator connects the input end electromagnetic valve and the mouth electromagnetic valve of each fluid power motor working medium liquid.
Every fluid power motor has the fluid reservoir of input end working medium liquid respectively, the fluid reservoir of mouth working medium liquid.
The fluid reservoir of every public input end working medium liquid of fluid power motor and the fluid reservoir of a mouth working medium liquid.
Bridge motor is connected with fluid power motor (also being referred to as pump-motor), when elevator travels downwards, electrical control part is opened the fluid reservoir media fluid input end of working medium liquid and the electromagnetic valve of mouth, fluid power motor arrives the working medium liquid pump of the fluid reservoir of the working medium liquid of elevator below, the fluid reservoir of the working medium liquid of elevator top, potential energy converting and energy when elevator is travelled downwards becomes working medium liquid potential energy to store, and can save elevator power motor energy consumption.
When elevator upwards travels, electrical control part is opened the fluid reservoir media fluid input end of working medium liquid and the electromagnetic valve of mouth, fluid power motor promotes the fluid power motor acting with the working medium liquid of the fluid reservoir of the working medium liquid of elevator top, the potential energy converting and energy of the working medium liquid of elevator top storage becomes the fluid power motor propulsion source, substitute a part of elevator power motor acting, and can save elevator power motor energy consumption.
If disregard conversion efficiency loss and fricting resistance loss elevator not energy requirement input just can move, therefore this is that the operation power consumption of motor is the running resistance of elevator and the waste of power of pump-motor system conversion efficiency, this numerical value is very little, therefore this device can reduce the operation energy consumption and the cost of elevator and hoisting crane greatly, if with several pump motor series connection, in service according to different loads, gravity sensing device can start the pump-motor of respective number, can better reach energy equilibrium purpose in service, the current peak that is motor further reduces, and reaches better energy-conservation purpose.
