The structure of the internal gear pump

Author:


The internal gear pump is a gear pump with special acid resistance and wear resistance. Its characteristics are: install the active shaft and the ordinary attack shaft on the shell, install the transmission fish on a section where the active shaft is located in the shell, install the transmission fish meshing with the transmission fish teeth on the ordinary attack shaft, make a pair of transmission fish, set the inlet and outlet of raw materials on the shell, and set ceramic fiberboard on the inner cavity of the transmission fish pair under the cover content. The equipment improves the acid resistance and wear resistance of the gear pump according to the change of gear pump structure.

The internal gear pump leaks during the installation of static test, and the internal motor rotor of the gear pump in the application is the active wheel, and the external motor rotor is the active wheel. Since the number of drive gears of the internal and external motor rotors is less than 1 tooth, due to the presence of a secondary clutch during clutch warfare, several separate closed gun fluid cavities may be created. The teeth of the internal and external motor rotors rotate together, and the capacity of each shell cavity changes differently. When the capacity of the cannon liquid cavity changes from small to large, a partial vacuum pump will be generated in the liquid cavity, and under the effect of atmospheric pressure, the liquid enters the pump cavity according to the annular groove on the inlet pipe and the pump cover to start suctioning, if the cannon liquid cavity capacity exceeds large. The entire process of the inhalation liquid is completed. When the volume in the cannon fluid chamber changes dramatically due to changes. The liquid in the cannon liquid chamber is pressed into other circulation cylinders for the whole process of pump discharge. Internal gear pumps produce relative speeds during the working process, during which the internal and external motor rotors work in the same direction at different speeds when the two center lines around the faces parallel to each other are worked. This fitness exercise creates an ever-changing indoor space between the internal and external motor rotors. Because it is connected to the inhalation drain, it exceeds the destination of the inhaled liquid.

Internal gear pump is a slightly corrosive or hygienic substance, no solid particles and chemical fibers, suitable for wetting liquids with a temperature of not more than 280 and a viscosity of no more than 2000cst. In order to be able to use different working conditions, pump products capable of designing a variety of different metal materials are used to use different corrosive substances. The core materials of common gear pumps are 304, 316, 316L and other metal materials. All gear pump component materials are solved with organic chemistry according to a unique processing process and have high corrosion resistance, wear resistance and impact resistance. The core products of gear pumps include casting products, ordinary sand casting products, precision casting products, silica sol precision casting products, etc. Exquisite appearance, beautiful appearance, low noise, long use time and other characteristics. It is the first choice product for chemical plants and corrosive machinery and equipment supporting facilities. KCB series products gear oil pump electric gear selection involute gear bevel gear structure, with corrosion-resistant rubber skeleton seal and PTFE high temperature packing seal composed of assembly line, good sealing, high temperature. Unique operating conditions standard can be selected stainless steel plate in-plate corroser seal.

Maintenance process of internal gear pump

The transmission gears of the internal gear pump generally have straight teeth, bevel teeth, herringbone teeth, helical teeth, and tooth profile keys have involute gears and arc gears. Generally speaking, small and medium-sized gear pumps mostly use involute gear spur gears, high-temperature gear pumps commonly use displacement gears, and low viscosity, polymer dissolved melt pumps commonly use involute gear bevel gears.

Internal gear pump, do you understand?

The structure of the internal gear pump has the characteristics of simple, convenient processing, small size, light weight, strong self-absorption capacity, and insensitivity to oil pollution, and is widely used. China's gear pump industry has two major competitive advantages, on the one hand, it has the competitive advantage of low cost; At the same time, the rapid growth of domestic construction, petroleum, petrochemical and environmental protection markets and major water transfer projects have also provided important support for the development of China's gear pump industry.
