The invention relates to an intelligent online closed-loop pumping unit balance adjustment system, which comprises a connecting rod, a balance weight, a transmission device, a balance weight displacement adjustment motor and a control device for driving the motor to adjust and control the displacement...
This disclosure relates to a closed loop heat pump system for use in multizone buildings in which the closed loop is connected through a plurality of individual zone units. The zone units are heat pumps of the type which include reversible refrigerating apparatus. The closed loop circulates a he...
usually mounted on the back of the motor, is fed to special inputs which allow the drive to measure the speed, direction of rotation, and sometimes the position of the motor shaft. But the same care needs to be taken as with any closed loop system. Is the signal from the encoder corre...

A method for removing contaminants from a surface such as pavement using a portable closed-loop system which is transported to the location to be cleaned by a vehicle. The method includes storing a volume of fluid in a clean tank, pumping the fluid to a cleaning head, blasting the surface ...
A closed circulatory system keeps blood within vessels, never allowing it to flow into the open spaces around internal organs. It includes at least one true heart that acts as a pump and a network of closed vessels that carry blood in a unidirectional loop throughout the body. The heart pum...
The adjusting of the pumping parameters can be configured to, for example, help the user efficiently express milk by utilizing a closed-feedback system that monitors the flow rate of the expressed milk.收藏 引用 批量引用 报错 分享 文库来源 求助全文 CLOSED LOOP ELECTRIC BREAST PUMP 优质文献 ...
One type of open-loop system is sometimes referred to as a pump-and-dump system. That pretty much tells you how it operates. You pump water from the ground or a pond, run it through the heat exchanger, and dump it onto the surface or into a storm sewer. That type is widely illegal...
A closed-loop testing system enables flowing back wells in ultrahigh-H2S environment closed while mitigating HSE risks.
A closed-loop piezoelectric pump is disclosed for use in a fluid delivery system. The pump housing includes a movable diaphragm that defines a pumping chamber within the pump housing, the pumping chamber having an inlet for admitting flu... ...
