Structure and working principle of lubricating oil pump
Release time:
2021-11-12
The lubricating oil pump is mainly composed of pump body, gears, shaft, bearings, front and rear covers, sealing components, couplings and other components. There are two forms of shaft end seals: packing seals and mechanical seals. When the meshing gears rotate inside the pump body, the teeth continuously enter and exit the meshing. In the suction chamber, the gear teeth gradually disengage, causing the volume of the suction chamber to gradually increase and the pressure to decrease. The liquid enters the suction chamber under the pressure of the liquid surface and enters the discharge chamber with the gear teeth. In the discharge chamber, the gear teeth gradually enter the meshing state again, and the teeth between the gears are gradually occupied by the teeth of a gear. The volume of the discharge chamber decreases, and the pressure of the liquid in the discharge chamber increases. Therefore, the liquid is discharged from the pump outlet, and the gear continues to rotate, forming a continuous oil delivery process.

Thin oil dispersed lubrication: There are two types of thin oil dispersed lubrication: manual lubrication and fully automatic lubrication. Manual lubrication is generally only used for small parts that are not frequently moved
Thin oil lubrication uses mineral oil as a lubricant. Thin oil has characteristics such as fluidity, adhesion to metal surfaces, certain viscosity and heat capacity, and stable lubrication performance. It also has a certain anti-corrosion effect. However, thin oil is not easy to seal, and the lubrication surface of equipment is prone to impurities such as water and iron oxide scale.
The types of rubber flexible vibration damping soft joint products should be assembled according to the assembly instructions during installation, otherwise product damage and other common problems may occur. To avoid the occurrence of the above-mentioned situation, please strictly follow the installation and use manual for the operation process. Rubber shock-absorbing soft joints have good comprehensiveness and can be used to connect valve fittings, vibrating pipelines, and pipelines with frequent changes in temperature. Rubber flexible vibration damping soft joint assembly is commonly found in the fields of sea surface, water, cold and hot water, drinking water, domestic sewage, light fuel oil, lubricating grease, wholesale of finished oil, steam, natural gas, steam and fine particulate matter powder. The series circular vibrating screen motor is connected to the exciter using a flexible coupling. The exciter can be disassembled and replaced as a whole. The bearings are lubricated with thin oil, and lubricating oil can be added once during operation, making maintenance and upkeep convenient.
Oil air lubrication is a new type of lubrication method that mixes thin oil with compressed air or nitrogen to form an oil air flow, which is transported to the friction lubrication point through pipelines in the form of fine oil droplets. The methods of continuous and intermittent gas supply can meet the continuous and stable lubrication needs of continuous casting equipment.
