Problems solved by technology

Therefore, to expand the flow rate of the screw pump, the first choice is to increase the diameter and pitch of the screw. The limitation of many factors such as technology makes it more and more difficult to increase the flow rate of the pump.

Abstract

The invention discloses a parallel connection type double-screw-rod pump, which comprises a pump body, a pump core, a medium gateway, a front end cover, a back end cover and a machine sealing cover, wherein the middle of the pump cover is a pump cavity. The invention is characterized in that the right end of a gear shaft is connected with a main shaft of a driving machine, the left end of the gear shaft extending into a gear cavity is sheathed with a main gear, two groups of mutually engaged driving screw rods and driven screw rods are placed in the pump cavity, two driving screw rod gears are respectively engaged with the main gear, and a driving screw rod friction wheel positioned in a back cavity is mutually engaged with a driven friction wheel. The invention transfers the motive power to the driving screw rods through the engagement of gear shafts and the two driving gears, and then, the driving screw rods transfer the driving torque to the driven screw rods. The invention has the advantages of capability of effectively saving energy and reducing consumption, compact structure, small size and low manufacture cost. The flow rate of the pump can be improved by one time under the conditions that the diameter and the pitch of the screw rods are not enlarged, and the rotating speed of the pump is not improved.

Description

technical field [0001] The invention relates to a screw pump, in particular to a parallel twin-screw pump. Background technique [0002] The screw pump is a positive displacement pump, and its theoretical flow rate is proportional to the diameter, pitch and rotational speed of the screw. Therefore, to expand the flow rate of the screw pump, the first choice is to increase the diameter and pitch of the screw. The limitation of many factors such as technology makes it more and more difficult to increase the flow rate of the pump. Contents of the invention [0003] The purpose of the present invention is to provide a parallel twin-screw pump that can effectively save energy and reduce consumption, has a compact structure, a small volume, and low manufacturing cost. It neither expands the diameter and pitch of the screw nor increases the rotating speed of the pump. On the contrary, it can double the flow rate of the pump. [0004] The purpose of the present invention is ach...
