Gear pump structure instructions
Gear pump structure Description: Gear pump is suitable for conveying a variety of lubricated liquids, the temperature is not higher than 70 ℃, contact with the unit can be equipped with high temperature materials, the viscosity of 5 × 10-5 ~ 1.5 × 10 -3m2 / s. Gear pump is not suitable for conveying corrosive, hard particles or fibers, highly volatile or low flash point liquid, such as gasoline, stupid and so on. Gear pump equipped with a pair of rotary gear in the pump body, relying on the two gears intermeshing, the pump within the entire working chamber is divided into two independent parts. When the pump is running, the driving gear drives the driven gear to rotate. When the gear disengages, a partial vacuum is formed on the suction side, and the liquid is inhaled. The sucked liquid fills each tooth valley of the gear to the discharge side and the liquid is forced out of the pump when the gear enters into engagement. Gear pump from the pump, gear, before and after the pump cover, safety valve, bearings and seals and other zero, components. Pump body, front and rear covers and other parts of gray cast iron, gear made of high quality carbon steel; can also be based on user needs with copper or stainless steel. 2CY series gear pump itself without safety valve, users need to use their own pipeline system installed in the safety valve. KCB, 2CY series gear pump installed in the rear pump cover or pump body above the safety valve, when the pump or discharge pipe failure or the discharge valve is completely closed to produce high pressure and high pressure hit the safety valve will automatically open, unloading In addition to some or all of the high-pressure liquid back to the suction chamber, which pumps and pipes play a safety role.
