Tai tell you gear pump impeller and pump housing important role

 Many types of gear pumps, but no matter what kind, impeller and pump housing are important components, there are many people because of improper operation of the use of these components, performance, and operational errors do not know. Understanding of the characteristics of the relevant parts of the pump is conducive to the operation and maintenance of the equipment, reduce the use of the issue. Gear pumps before starting the need to first shell covered with a liquid to be transported, the shaft drives the impeller to rotate together after startup, forcing the liquid between the blades rotate. Liquid under the effect of centrifugal force of inertia thrown from the outer periphery of the impeller center and access to the energy that flows to the outer periphery of the impeller fluid static pressure increases, the flow rate increases, up 15--20m / s. Gear pumps use a large area of ??low pressure gas piston (2-8bar) to produce high-pressure gas / liquid in a small area of ??the piston drive. It can be used for compressed air and other gases, the output pressure by driving pressure stepless adjustment. Gas pipeline pump gear pumps are single acting and double-acting pump. Double-acting pump two-stroke gas piston reciprocating are compressed gases. When the driver of the gas on gas piston, working piston with the gas drive can achieve greater output flow. After the liquid exits the impeller into the pump housing, because housing is gradually widened, so that the liquid flow channel deceleration, kinetic energy is converted into static pressure energy sector. Just constantly rotating impeller, the liquid will be continuously suction and discharge. Inseparable from the role of running gear pump impeller and pump housing and its accessories action, part of the equipment of its use are helpful, so in order to ensure the normal operation of its constituent parts must be a good performance. Our main products are: screw, stainless steel gear pumps, gear pumps, rotary pump, oil pump series. http://www.clb678.com
