JB-70-type hand, electric dual metering pumps operating procedures

JB-70-type hand, electric dual-purpose metering pumps for the blade-type overflow valve device, when the tank full of fuel, to close the oil gun, the vane pump can continue to work, hydraulic Exceeds the rated pressure when the pump relief valve that automatically acts. So in practice, what procedures should we follow? Now to tell you about JB-70 type hand, electric dual-use metering pump operating procedures. JB-70 hand-operated, electric dual-purpose metering pump operation procedures (1) Turn on the power, rotate the explosion-proof motor knob to "open a position. (2) plate tight oil gun knob out of oil, this time Flow meter at the same time began to count. (3) release the handle handle oil that is stopped, then the count value is the amount of fuel (or difference between the second reading is the amount of fuel) (4) stop working, should First explosion-proof motor knob to "off a position, and then cut off the power switch, around a good rubber cables and so on.

Double-concave Cylinder Lens

Cylindrical lenses have at least one surface that is formed like a portion of a cylinder.Cylindrical lenses are used to correct astigmatism in the eye and in rangefinders, to produce astigmatism,stretching a point of light into a line.They are available in either plano-concave or plano-convex configurations. Plano-Concave Cylindrical lenses have a negative focal length and are used for image reduction or to spread light. Plano-Convex Cylindrical lenses have a positive focal length, which makes them ideal for collecting and focusing light for many imaging applications.

Some styles of cylindrical lenses have antireflective coatings to increase the transmission of light through the lens. Fused silica cylinder lenses are ideal for demanding laser machining and medical applications.

Plano-convex cylinder lens,Plano-Concave Cylinder Lens,Double-Convex Cylinder Lens,bi-concave cylinder lens,Meniscus Cylinder Lens, Rod Cylinder Lens ,Achromatic cylinder lens are available.
