Found through my research, before the lifting mechanism from the quantitative motor, but with the development and the increasing demand of lifting appliances, existing mechanical manual quantitative solution of the pump is less than design requirements for use, after investigation, I decided to use

After my research found that in previous quantitative motor, however, as the cranes and the improvement in my existing mechanical manual dosing fluid up to pump less than design the requirements for use as a result of the investigation, so I decided to use commercial QJM low quantitative motor, this

Studies the discovery after me, lifts the organization beforehand quota motor, but along with the hoisting machinery development and the request enhancement, in myself existing mechanical handbook the quota fluid reaches the pump not to the design use request, therefore myself pass through the inves

After I research found, up rose institutions yiqian of quantitative motor, but as lifting machinery of development and requirements of improve, I existing machinery manual in the quantitative liquid up pump does not to design using of requirements, so I after investigation decided using commercial Q
