Description

Swing mechanism and pumping system thereof

Technical Field

The utility model belongs to a pumping mechanism technical field, concretely relates to swing mechanism and use its double pump system.

Background

The pumping mechanism plays an important role in the pumping process of engineering machinery materials such as concrete. During pumping, the pumping mechanism sucks concrete from the hopper and pumps the concrete out of the distribution valve, so that the concrete is pumped.

When concrete or industrial materials need to be delivered to two designated places through two delivery pipelines under the condition that only one delivery device is arranged or only one delivery device can be arranged, a common solution is to adopt a special distribution valve, such as a lifting distribution valve, in a pumping system to enable two delivery cylinders to work independently and respectively correspond to the two pipelines for delivery, so that the two pipelines can be delivered independently without mutual interference. Each delivery cylinder undergoes a repeated alternating process of suction and pumping. The reversing mechanism and the swing oil cylinder in the existing pumping system are transversely arranged, so that the pumping system is ultra-wide in transverse width and occupies a large assembly space, the single swing cylinder of the swing oil cylinder is insufficient in working pressure and unbalanced in stress, and accordingly the working efficiency of the pump is low.
