DHS type electric chain electric hoist is a light and small substitute product for manual hoist, which is used to reduce the labor intensity of the operator. The hoist is composed of a hoist body, a disc motor and a reducer, and is suitable for lifting the outer frame of high buildings and equipment. Installation, road and bridge engineering and other occasions where the lifting speed is slow or intermittent work. Reasonable design, advanced structure, beautiful appearance and fine workmanship.

Flexible throttle work principle and the use of important points introduced
Flexible throttle valve works diagram, relying on stem flexible rubber tube clamping and throttling effect, you can also use the gas pressure instead of valve stem compression hose. Flexible throttle valve structure is simple, lower pressure, high reliability. Not sensitive to pollution, the working pressure range is usually 0.3-0.63MPa. Pneumatic flow control valve pneumatic actuator for speed control than the use of hydraulic flow control valve speed control difficult because of the gas compression. Therefore, the use of pneumatic flow control valve speed should pay attention to the following points, in order to prevent the occurrence of crawling: (1) the pipeline can not have leakage; (2) cylinder, piston lubrication state better; (3) flow control valve should be as Installed in the cylinder or gas motor near; (4) as far as possible the use of throttling speed control mode; (5) the applied load should be stable. If the external load changes greatly, hydraulic or mechanical devices (such as gas-liquid linkage) should be used to compensate for the speed changes caused by load changes.
