How to maintain the cycloidal gear pump to make it last longer?
The cycloidal gear pump works by interlocking the two gears, and Botaibang does not require high media. The general pressure is below 6 MPa and the flow rate is large. The cycloidal gear pump is equipped with a pair of slewing gears in the pump body, one active and one passive, and the two working parts in the pump are divided into two separate parts by the mutual engagement of the two gears. A is the suction chamber and B is the discharge chamber. When the cycloidal gear pump is in operation, the driving gear drives the driven gear to rotate. When the gear is engaged to disengage, a partial vacuum is formed on the suction side (A), and the liquid is sucked. The inhaled liquid fills the respective valleys of the gear and is brought to the discharge side (B). When the gear enters the mesh, the liquid is squeezed out to form a high-pressure liquid and exit the pump through the pump discharge port.
1, often fatliquoring, electric drum pump for high-speed operation, grease is easy to volatilize, so the lubrication at the bearing must be kept clean, and pay attention to add.
2. Note that the electric pump should be placed in an environment that is dry, clean and free of corrosive gases.
3, cycloidal gear pump often check maintenance, electric oil drum pump should be checked frequently, maintenance, must check the power cord: internal wiring, plug, switch is good, insulation resistance is normal, brush tail seat is loose, commutator and The brush contacts are good, whether the armature windings the stator windings are properly interrupted, whether the bearings and rotating parts are damaged, and so on.
4, cycloidal gear pump pay attention to insulation resistance, long-term unused electric pump used in humid environment, the insulation resistance of the winding must be measured with a 500 volt megohmmeter before use. If the insulation resistance between the winding and the motor casing is less than 7 megohms, the winding must be dried.
5. Save each part and exchange the same parts. When disassembling the gear oil pump, each part should be preserved. Pay special attention to the explosion-proof surface of the explosion-proof parts, which can not damage the wool, including the insulating gasket and casing. For damage, the same new parts must be replaced. Substitute materials that are lower than the performance of the raw materials or parts that do not conform to the original specifications shall not be used. All parts shall be assembled in the original position during assembly and shall not be missed.

Magnesium Fluoride (MgF2) Windows offer excellent broadband transmission from the deep-UV to the mid-infrared.
MgF2 is a rugged material resistant to chemical etching, laser damage, and mechanical and thermal shock.
MgF2 exhibits excellent broadband transmission from 120 nm to 8 μm , from the deep UV to the mid infrared. This makes them a good choice for UV radiation sources and receivers as well as for use at the Hydrogen Lyman-alpha line. They are often used as UV viewpoints, and are a good option for UV polarizers and excimer laser applications. It has a high transmittance between 120 nm and 8 µm, and between 0.4-5.0 µm transmits over 90%.
MgF2 has a melting point of 1255 degrees Celsius. It has a density of 3.177 g/cm3, and a tetragonal crystal type. Our optical windows are typically oriented with the round surfaces perpendicular to the c-axis of the MgF2 crystal to minimize birefringence. Custom random cut MgF2 windows can be manufactured on request.
MgF2 is the only optical material which combines a wide spectral transmission band with birefringence. This birefringence means that the refractive index depends on the polarization and propagation direction of light. Because of birefringence, a MgF2 window can exhibit double refraction, so that a ray of light will be split by polarization into two rays with different paths.
- Excellent Transmission from 120nm to 7μm
- Rugged and Durable
- Resistant to Chemical Etching
