Internal gear pump maintenance
Internal gear pump the common gear pump of a constructor and truth, which is running smooth and the use of life was significantly better than existing gear pump. New gear pump is the smallest unit displacement pump "as optimization purposes, and progress in the pump price.
The primary characteristics of the internal gear pump: ① radial hydraulic pressure, radial meshing force balancing, greatly improved pump life and reliable; ② The pump output displacement and flow, flow pulsation. Making new products with higher added value and competitive advantage, to deal with the lack of traditional gear gear pump to supply the new road to replace the existing gear pump, screw pump, petrochemical, light industry, food areas of high viscosity liquid walks in other industries to open up the application prospects. Open up the use of eras in the few well advanced space.
In the petrochemical industry, the high-viscosity liquid (such as synthetic rubber, resin, fiber polymerization solution, etc.) walks is one of the major consumer process, and the machinery used to complete the liquid walks are various ways pump because dope higher viscosity, pump the liquid absorbent greater resistance, in order to ensure the self-priming pump has given can weekdays and by positive displacement pump walks high viscosity liquid gear pump is the most simple kind of positive displacement pump, because of its simple structure , light weight, low cost, and a large viscosity change limitations is not sensitive to the dirt in the liquid, at a high viscosity pump suction performance is good, reliable work, so commonly used in the more harsh and not high precision request place walks viscosity liquids. follow the new craft, new data, new techniques have emerged from time to time, snapped past that Eph into high-viscosity liquids can be walked through the discussions and improvements can also be used within the gear pump walked the addition, internal gear gear pump can also be used as a high-viscosity liquid supercharger, inclusions, metering and spinning. inner meshing gear pump liquid walks often solid at room temperature, as a liquid only in the insulation condition. thus, internal gear pump in walks these liquids, not only needs to address the problems brought about by the high-viscosity, along with high temperature, erosion and other extraordinary and often dissect the wrong type and prevention countermeasures discuss internal gear pump, as cut wrong downtime when progress pump work quality, wrong type, including useful wrist, to delay the use of life are increasingly being people-oriented. internal gear pump gear pump problems in the diagnostic work, it was discovered that, not a sudden attack of gear pump large local problems, advance Rhyme accompany some signs, such as vibration, noise, leaked, fever, carried out to a certain level before incur problems if these signs can be found in real-time, and unchecked or sweep on the reduction of the probability of the internal gear pump presents illnesses. thus understanding of internal gear pump the typical wrong type, help to dissect its connotation contact to further attack certainly wrong category and wrong reasons, parts of.
1, no the export pressure or pressure lack
It is worth noting that the pump and can not pressure the it just output flow. Low pressure or no pressure, no inhalation liquid clarify
internal gear pump leaked serious.
Countermeasures: electric idea output power is too small, the pressure will form the lack of gear pump displacement the election too large or too high a pressure regulator. Course, also showed no the pressure gauge damage or pressure gauge thrift hole infarct pressure, this when you install a new pressure gauge search seized.
2, no flow, or a lack of fluid volume
If the free flow output pump, it may be because of the pump device, pump steering error absurd, or the suction side of the infarction (liquid inlet and suction piping), the outlet check valve installed backwards or stuck, there may drive shaft fracture. internal gear pump speed is too low will cause a lack of fluid volume, a phenomenon often slipping or power from its lack of pump drive installation you should search seized practice speed gear pump, pump and the electricity idea of the connection and power matching condition
3, abnormal vibration and noise
Stimulate greater noise internal gear pump high viscosity of the working medium, and thus easily sucked empty phenomenon occurs.
