Abstract
The utility model relates to a novel liquid ring vacuum pump which comprises a main shaft, an impeller thermally installed on the main shaft and a pump shell wrapped outside the impeller. The novel liquid ring vacuum pump is characterized in that front and rear cone-shaped distributors are connected to two sides of the impeller, both ends of the main shaft are supported through front and rear bearings, and the front and rear bearings are respectively installed in a bearing room. According to the novel liquid ring vacuum pump provided by the utility model, key technical parameters such as molded line, dip angle and radius of curvature of the impeller are optimized in design by way of theoretical modeling, physical simulation and design and the like, so that the purposes of reducing the energy consumption and improving the sucking rate are realized.
Description
Technical field
The utility model relates to a kind of novel liquid-ring vacuum pump.
Background technique
Liquid-ring vacuum pump is that rotation motion in pump chamber makes the vacuum pump of swept volume of a single chamber cyclically-varying to realize bleeding by the biasing impeller.Its working room is made of rotation pendular ring and impeller blade, and its structure is similar to liquid rotary compressor with working principle.Along with energy consumption, efficient, the reliability requirement of industries such as colliery, papermaking, petrochemical industry to equipment improves constantly, especially handling the poorest occasions of working condition such as high dusty gas, the unpurified gas that contains soft fibre, the gas of carrying partially liq secretly, high-temperature gas, poisonous or corrosive gas, existing liquid-ring vacuum pump can't satisfy the industry needs.
The model utility content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide that a kind of energy consumption is low, axial clearance is big, the suction and discharge passage is big, rate of air sucked in required is high, be convenient to keep in repair the novel liquid-ring vacuum pump of use.
Novel liquid-ring vacuum pump provided by the utility model, comprise liquid-ring vacuum pump, the liquid ring vacuum pump structure comprise main shaft, hot charging on main shaft impeller and be coated on the pump case of impeller outside, it is characterized in that, the both sides of impeller are connected with forward and backward conical distributor, the two ends of main shaft are supported by fore bearing and rear bearing, and forward and backward bearing is installed in the bearing chamber respectively.
The range of taper of forward and backward conical distributor is 7～10 °.
The impeller relative length is 1.7～2,110 °～120 ° of blade tilts, blade Relative radius of curvature 0.292～0.297.
Being connected between described bearing chamber and the pump cover adopted split-type structural.
The beneficial effect that the utility model has is, utilizes modes such as theoretical modeling, entity board design, and critical technical parameters such as impeller profile, inclination angle, radius of curvature are optimized design, reaches the purpose that cuts down the consumption of energy, improves rate of air sucked in required.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Novel liquid-ring vacuum pump as shown in Figure 1, comprise main shaft 1, hot charging on main shaft 1 impeller 9 and be coated on the pump case 4 of impeller 9 outsides, the both sides of impeller 9 are equipped preceding conical distributor 7 and back conical distributor 8 respectively, the two ends of main shaft 1 adopt bearing to support, two ends are respectively the fore bearing 3(bearing that moves about) and rear bearing 5(positioning bearing), forward and backward bearing be installed on fore bearing chamber 10 respectively and rear bearing indoor, the split-type structural design all with pump cover 6 is adopted in fore bearing chamber 10, rear bearing chamber, be convenient to assembling, also make things convenient for device maintenance simultaneously.
The range of taper α of the conical surface of preceding conical distributor 7 and back conical distributor 8 is 7～10 °.Impeller 9 relative lengths are 1.7～2, and blade tilt β is 110 °～120 °, blade Relative radius of curvature 0.292～0.297.The suction and exhaust ports mode of the conical distributor of this range of taper is radial structure, the suction and discharge passage is big, the stroke of gas in pump chamber is short, flow resistance is little, the corresponding specific efficacious workaround of different suction and exhaust ports areas, compare with flat disk formula vacuum pump, at different vacuum areas, energy-saving effect reaches 10%～30%.
