LH-80 hand electric dual-purpose metering pump maintenance

In the process of using, LH-80 manual electric dual-purpose metering pump needs regular maintenance so as to maintain the performance of the equipment for a long time, improve working efficiency and prolong service life. Next, Xiaobian tell you LH-80 hand-electric metering pump maintenance methods, the specific practices can refer to the following: LH-80 hand-electric metering pump maintenance 1, should often Check the vane pump, flow meter oil gun and the smooth flow of oil within the pipeline, if not smooth should promptly find the cause and maintenance. 2, always keep the conductive rubber wheel clean, and prevent the coating of insulating dirt. 3, mobile, maintenance LH-80 type hand electric dual metering pumps, the power supply should be cut off and the explosion-proof switch knob to "stop straw position" to avoid unsafe accidents caused by live operation. 4, into the pipe end filter should always check the cleaning. Loose tube cleaning screw can be drawn out of the filter, be careful not to break the filter cleaning, broken filter should be promptly replaced. 5, LH-80 hand electric dual-purpose metering pumps total work 500 hours, the vane pumps, oil guns, piping and other demolition seized, cleaning. 6, in order to simplify the structure, LH-80 type hand electric metering pumps do not match the lighting, such as the user to observe the number of counters required, should be equipped with explosion-proof lights, the use of ordinary lamps and flashlights and so on. The above is the LH-80 hand electric metering pump maintenance details, from the above description, we know that cleaning is very important, you need regular inspection and cleaning. Therefore, to measure the long-term fuel pump work, users have to diligently, do a good job of this maintenance work.

Plane Ruled Grating

Plane ruled gratings are characterized by a superior efficiency at their design wavelength compared with holographic gratings. Plane Ruled gratings comprise the majority of diffraction gratings used in spectroscopic instrumentation and are especially useful in systems requiring high resolution.

China star optics can provide customers with a variety of replicated grating products such as diffraction gratings, reflective gratings,holographic gratings,concave gratings etc. to meet different needs. Maximum ruled area is up to 300 x 300 mm for plane ruled diffraction gratings. For replicated diffraction and transmission gratings the ruling density can be from 20 grooves per millimeter to 2400 grooves per millimeter, wavelength from 0.2 micron to 25 microns.
