CH, CHY type gear oil pump is used for conveying viscosity at 200 ° E (below 1500 mpa. S) not containing solid particles and impurities machine oil, turbine oil and other media have similar lubrication performance and property, the temperature is not higher than 120 °.
CH and CHY gear pumps belong to volumetric pumps.Its unique structure has the ability of self-absorption, stable fluctuation, high pressure, low wear, long service life, wide application and high efficiency.
CH and CHY gear pumps are provided with safety valves as overload protection, and the full return pressure of the safety valves is 1.5 times of the rated discharge pressure, which can be appropriately adjusted within the scope of the actual process requirements of the users.However, the relief valve cannot work for a long time and can be installed separately on the pipe when needed.
CH and CHY gear pumps are widely used in national defense research, petroleum, chemical industry, power generation, metallurgy, transportation, pharmaceutical, food and other departments.According to the needs of the process can also be derived into heat pumps, asphalt pumps, anti-corrosion pumps.
Gear oil pump maintenance
1. Add grease frequently. The motor oil drum pump runs at high speed, and the grease is easy to volatilize. Therefore, it is necessary to keep the lubrication of the bearing clean and pay attention to adding and replacing.
2, check repair gear pump, electric oil pump should be regularly check, repair, must check the power cord, wire, plug, switch are in good condition, whether the insulation resistance is normal, brush the tailstock is loose, commutator and brush contact is good, the armature winding expansion of stator winding is a moderate level open circuit phenomenon, whether the damage of bearing and rotating parts and so on.
3, keep each parts and exchange the same parts, when overhauling the gear oil pump, should keep every parts, it is important to pay special attention to the explosion-proof surface of flame-proof parts does not make the damage hair including insulation gasket and casing, if there are any damage, must change the new parts, the same shall not adopt any of below raw material substitute materials or the performance of the original specifications of parts, assembly all parts should be packed according to the original position, can't miss.
4. The gear oil pump shall pay attention to the insulation resistance, and the electric pump which is not used or used in wet environment for a long time must be measured with 500v megohm meter before use.If the insulation resistance between the winding and the motor casing is less than 7 megohm, the winding must be dried.
5. Keep the electric pump in a dry, clean and non-corrosive environment.
