introduction:2、The sensor of the digital water level controller is installed vertically in the measured liquid,Under the action of liquid buoyancy,A float with magnetic steel inside,Displacement occurs as the liquid level changes。The magnetic field of the magnetic steel acts on the humidity in the sensor detection tube(dry)Reed pipe,Make its contacts pull or break,Forms a change in the output resistance value of the sensor。The change of resistance value is converted to the corresponding by the display tableLEDLed lights out,Thus, the change of the measured liquid level can be simulated,When the liquid level is wet in two(dry)There is no suction between the reed tubes,The display table remains in the previous position,Until the next wet(dry)Reed action,Make sure there are no dark areas。

introduction:About the multi-point electric dry pump,We may simply understand,The hydrostatic lubrication of multi-point electric dry pump may not be well understood,today,Let my company take you to have an in-depth look at its static pressure lubrication,Specifically as follows。 Multi-point electric dry pump through a set of high pressure hydraulic oil supply system,Apply a certain pressure of lubricating oil to the throttle damper,Forced into the gap between the friction surfaces of the motion pair,Such as in the clearance of static bearing、Flat static pressure sliding guide in the gap、Static pressure screw clearance medium。The friction surface has not yet begun to move,Its separated by a high-pressure oil separator,Force an oil film,Thus, it ensures that the motion pair can withstand certain working load conditions,Fully liquid lubricated,This lubrication is called hydrostatic lubrication。

introduction:The Hanto speed belt Hanto as a belt manufacturer in the international port city of Kobe since the establishment,It has been nearly a century,In the meantime, the first conveyor belt in Japan was produced、VV-shaped belt and tooth belt,With a coherent development policy,Strive for perfection in power conveyor straps and systems。The variable speed belt has two kinds of structure, covering or cutting edge,The special characteristics of the rubber fiber determine high lateral stiffness and longitudinal flexibility at the same time,High load capacity and long life。Cast teeth reduce heat buildup or stress concentration,Extend belt life。Smooth running structure allows the belt to operate at high speeds with only minor changes。
