Abstract
The utility model belongs to the field of screw heat pump unit damping, and particularly relates to a screw heat pump unit damping device which comprises a tank, a hydraulic cylinder, an energy storage device and an air pressure bumper. The screw heat pump unit damping device is characterized in that the hydraulic cylinder is connected to the bottom of the tank, the hydraulic cylinder is connected with the energy storage device, and the energy storage device is connected with the air pressure bumper. Through compression of air, mechanical vibration is converted to air internal energy, the influence of vibration of the heat pump unit in work is avoided, and the damping effect is achieved.
Description
Technical field
The utility model belongs to hot screw pump unit damping field, is specifically related to a kind of hot screw pump unit damping device.
Background technique
Heat pump unit is applied very wide aspect the heating and refrigeration of building, the heating of a lot of popularity buildings and refrigeration are all relying on heat pump unit, heat pump unit has a lot of benefits, its Air Conditioning System unification, boiler room and refrigerator room are saved, without cooling tower, save resource and saved construction investment.
But heat pump is in running, and the mechanical vibration of generation are but the problems that needs solve, and the quantity of the heat pump that different buildings needs is different, heat pump is more, the vibrations that produce when work are just stronger, like this, resident around produced to bad impact.And the vibrations of heat pump also can cause certain destruction to equipment itself.
Model utility content
The purpose of this utility model is to solve the vibrations that heat driven heat pump unit produces at work, affects the problem of surrounding resident and infringement equipment of itself.
For this reason, the utility model provides a kind of hot screw pump unit damping device, comprises casing, also comprise oil hydraulic cylinder, accumulator and pneumatic buffer, it is characterized in that: oil hydraulic cylinder is connected to bottom half, oil hydraulic cylinder connects accumulator, and accumulator connects pneumatic buffer.
Described oil hydraulic cylinder is single-piston-rod hydraulic cylinder, and the piston rod of oil hydraulic cylinder is connected to bottom half.
Described oil hydraulic cylinder has four, respectively the position at four angles in tank floor.
Described accumulator comprises housing, filler opening, liquid container, dividing plate, air chamber, air outlet and base.
Described housing is placed on base, and dividing plate is positioned at housing neutral position, and housing is divided into two-part, and top is divided into air chamber, and bottom is divided into liquid container, and the place that is positioned at air chamber on housing has air outlet, and the place that is positioned at liquid container on housing has filler opening.
Described pneumatic buffer is mainly made up of the air bag of a compressible gas.
This hot screw pump unit damping device that the utility model provides, comprises casing, also comprises oil hydraulic cylinder, accumulator and pneumatic buffer, utilizes gas compression principle, mechanical vibration is changed into the interior energy of pressurized gas, reaches the effect of damping.
Below with reference to accompanying drawing, the utility model is described in further details.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment 1 structural representation
Fig. 2 is the utility model accumulator structural representation
Description of reference numerals: 1, casing; 2, oil hydraulic cylinder; 3, accumulator; 4, pneumatic buffer; 5, housing; 6, filler opening; 7, liquid container; 8, dividing plate; 9, air chamber; 10, air outlet; 11, base.
Embodiment
Embodiment 1:
As shown in Figure 1, a kind of hot screw pump unit damping device, comprises casing 1, also comprises oil hydraulic cylinder 2, accumulator 3 and pneumatic buffer 4, it is characterized in that: oil hydraulic cylinder 2 is connected to casing 1 bottom, and oil hydraulic cylinder 2 connects accumulator 3, and accumulator 3 connects pneumatic buffer 4.
The vibrations of sending when heat pump unit work, pass to casing 1, and casing 1 acts on oil hydraulic cylinder 2, and the liquid that compression hydraulic cylinder is 2 li enters accumulator 3, and in accumulator, liquid increases, and a part of gas can be compressed into pneumatic buffer 4, and pneumatic buffer 4 swelling pressure strengthen; After vibrations, due to pressure-acting, pneumatic buffer 4 can be compressed into accumulator 3 again by gas, and accumulator 3 gas pressures increase, and liquid can be compressed into oil hydraulic cylinder 2, and oil hydraulic cylinder 2 returns to home position, impels casing 1 steady.
Embodiment 2:
Described oil hydraulic cylinder 2 is single-piston-rod hydraulic cylinder, and the piston rod of oil hydraulic cylinder 2 is connected to casing 1 bottom.Oil hydraulic cylinder 2 has four, respectively the position at four angles in casing 1 bottom surface.
The cylinder body kiss the earth of oil hydraulic cylinder 2, in the time that casing shakes, the piston movement of oil hydraulic cylinder 2, cylinder body is motionless, and vibrations just can not be passed on ground like this.
Embodiment 3:
As shown in Figure 2, described accumulator 3 comprises housing 5, filler opening 6, liquid container 7, dividing plate 8, air chamber 9, air outlet 10 and base 11.Housing 5 is placed on base 11, and dividing plate 8 is positioned at housing 5 neutral positions, and housing 5 is divided into two-part, top is divided into air chamber 9, bottom is divided into liquid container 7, and the place that is positioned at air chamber 9 on housing 5 has air outlet 10, and the place that is positioned at liquid container 7 on housing 5 has filler opening 6.
Described pneumatic buffer 4 is mainly made up of the air bag of a compressible gas.
Air bag device has been realized gas repeatedly, after compression, due to the effect of pressure, can again return to reset condition, has so just guaranteed that casing 1 can be steady, and has made device have repetition damping property.
More than exemplifying is only to illustrate of the present utility model, does not form the restriction to protection domain of the present utility model, within the every and same or analogous design of the utility model all belongs to protection scope of the present invention.
