Screw pump operation should pay attention to what problems

Rod pump must be in the direction of the established operation to produce a certain suction row. Pump work, should pay attention to check the pressure, temperature and mechanical seal work. Shaft seal should allow a trace of leakage, such as leakage does not exceed 20-30 seconds / drop, then that normal. If the screw pump noise during work, which is often due to the oil temperature is too low, the viscosity of the oil is too high, the oil into the air, the coupling lost in the pump or excessive wear and other causes.

2835 Red SMD LED

2835 Red Smd Led manufacturer from China.


2835 RED SMD LED is deeply loved by their users because of the small size, the high bightnes and 2835 RED SMD LED have the cooling copper at the bottom, which can make the product to get out of the heat in time.
It is often used in LED lighting, LED Lamps, LED backlight, landscape LED, LED panel lights, LED furniture, grow light LED, fill light LED, LED aperture and other lighting products.

In addition, this 2835 red SMD LED have the angle like the through-hole LED so it belongs to the spotlight SMD LED. It have a len on the top of the SMD LED, which can make this 2835 SMD LED with angle like 30 degrees, 60 degrees.

We supply kinds of 2835 SMD LED with different wavelength from 365nm to 1550nm, which include the visible LED and the invisible LED.
In this catalog, we mainly introduce the 2835 red SMD LED.
