Abstract
The utility model provides a big discharge capacity of modified low pressure casting double -screw pump body structure which the characteristic with: including the fashioned pump body of integrative casting, the pump body includes inlet flange, outlet(discharge) flange, entry cavity, outlet chamber room, safety valve, screw rod chamber, pump footing, coil pipe heating chamber, the screw rod chamber is located pump body middle part to it is concentric with pump outlet(discharge) flange, pump footing, inlet flange is unanimous with the outlet(discharge) flange latus rectum, the area of entry cavity is 1.3~1.4 times of pump inlet flange area, coil pipe heating chamber is located screw rod chamber lower part, pump footing upper portion to communicate with each other with the pump intake cavity, safety valve is located the upper portion in screw rod chamber, the lower part of outlet(discharge) flange, with the integrative casting shaping of the pump body. Increaseed the advancing of pump, outlet(discharge) flange, made the whole operation of pump more steady, increaseed entry cavity area, the suction capacity of pump is better.
Description
Technical field
This utility model relates to field of fluid, and the low pressure huge discharge casting being specifically related to a kind of improvement is double
Screw rod pump body structure.
Background technology
2HC series pump is low pressure large discharge pump, it is adaptable to pressure is low, the operating mode that flow is bigger.On market
The conventional 2HC series casting pump housing, import and export is less than normal.Time actually used, the flow velocity of pump is bigger than normal, and pump shakes
Move and can increase.And pump intake chamber is less than normal, during termination of pumping, pump liquid storage is few, and the suction capacity of pump declines.Institute
With needs, pump body structure of the prior art is improved, increase the import and export flange of pump, make pump
Overall operation more steady；Increasing inlet chamber area, the suction capacity of pump is more preferable.
Utility model content
For the problems referred to above, the purpose of this utility model increases the import and export flange of pump, makes the whole of pump
Body operating is more steady；Increasing inlet chamber area, the suction capacity of pump is more preferable, it is provided that a kind of improvement
Low pressure huge discharge casting twin screw pump body structure.
This utility model solves above-mentioned technical problem and be the technical scheme is that the low pressure of a kind of improvement is big
Discharge capacity casting twin screw pump body structure, its feature with: include the pump housing of integrally casting molding, pump housing bag
Include inlet flange, outlet(discharge) flange, inlet chamber, outlet chamber, safety valve body, screw rod chamber, pump footing,
Coil pipe heating chamber, described screw rod chamber is positioned in the middle part of the pump housing, and concentric with pump discharge flange, pump footing, institute
Stating inlet flange consistent with outlet(discharge) flange latus rectum, the area of described inlet chamber is pump intake flange area
1.3～1.4 times, described coil pipe heating chamber is positioned at bottom, screw rod chamber, pump footing top, and with pump into oral cavity
Room communicates, and described safety valve body is positioned at the bottom of the top in screw rod chamber, outlet(discharge) flange, with pump housing one casting
Cause type.
Further, described safety valve body is circle ear, is that fillet is connected with the junction of the pump housing.
The utility model has the advantage of:
1, suction flange and inlet chamber are expanded so that during screw pump termination of pumping, pump is deposited the most, suction capacity
Increase；2, expand export flange and outlet chamber, reduces the flow velocity of pump, pump when greatly reducing work
Vibrations so that the overall operation of pump is more steady；3, safety valve body is unified with the pump housing so that casting wood
Type is simplified, saving machining cost, and compact conformation, beneficially marketing.
