Maintenance process of internal gear pump

2023-06-02 14:08

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.

The structure of the internal gear pump

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 working principle and maintenance method of the internal gear pump

Internal gear pumps are widely used in petroleum, chemical, shipbuilding, electric power, grain, petroleum, food, medical, building materials, metallurgy and defense research industries. Internal gear pump is through a pair of parameters and structure of the same involute gear rolling meshing, the tank in the low pressure oil to the operable high pressure oil important components, which is the engine mechanical energy into hydraulic energy power unit, today to introduce to you the internal gear pump working principle and maintenance method.

Classification, characteristics and applications of gear pumps

Gear pumps are generally divided into external meshing type (external gear pump) and internal meshing type (internal gear pump) according to the configuration mode of the meshing pair, and the internal gear pump includes a cycloid gear pump with a special tooth shape.

Features of internal gear pumps

Compared with the external gear pump, the internal gear pump mainly has the advantages of small size, small flow pulsation and low noise, but the processing is difficult and the use is limited. The tooth surface contact line at the meshing point here has always played the role of separating the high and low pressure cavities, so there is no need to set up a special flow distribution mechanism in the gear pump.

Learn about internal gear pumps in one minute

The internal gear pump adopts the principle of gear internal meshing, and the inner and outer gear pitch circle is close to one side, and the other side is separated by the pump cover with a "crescent plate". The active internal gear on the spindle drives the outer and external gears to rotate in the same direction, and the gears are separated from each other at the inlet to form negative pressure and suck in the liquid, and the gears are continuously embedded and meshed at the outlet to squeeze the liquid out.

What is the difference between an internal gear pump and an external gear pump?

The difference between internal gear pump and external gear pump is: different composition, different principle, and different leakage amount.

The structural difference between external gear pump and internal gear pump

External gear pumps consist mainly of a pair of bearing-supported gears and a housing with front and rear covers. The drive shaft extends out of the front cover and is sealed by a shaft seal. Bearing forces are absorbed by special bearing gaskets (thin-walled bearings) that are elastic enough to create surface contact instead of linear contact.
