The displacement of the high-viscosity rotor pump cannot be adjusted arbitrarily, which limits the application space of the high-viscosity rotor pump to a large extent. In recent years, with the development trend of high-viscosity rotor pumps, it has gradually exhibited high pressure. While increasing the working pressure, it also brings many common problems:
1. Greatly reduce the service life of high viscosity rotor pump bearings;
2. The increase of the end face and axial leakage of the high-viscosity rotor pump seriously reduces the volumetric efficiency of the pump. The failure of the radial pressure on the gear (shaft) to reach equilibrium is the main factor causing the above two shortcomings. And as people's demand for high-pressure pumps continues to expand, the working pressure required by the pumps is constantly increasing, which in turn causes the hydraulic pressure on the pumps to increase continuously. At present, many scholars have made the following improvements to these two drawbacks:
1. Compensate for radial clearance.
2. Optimize the gear parameters and reduce the radial size of the pump by reducing the geometric size of the discharge port.
3. Increase the load capacity of the bearing and use needle roller bearings to replace the original sliding bearings. However, none of these measures can substantially improve the performance of the pump.
The prime mover types of high-viscosity rotor pumps are very wide. High-viscosity rotor pumps are generally equipped with three-phase AC squirrel cage asynchronous motors, which is also a common type in the motor market. The motors generally include ordinary motors, explosion-proof motors, marine motors, marine explosion-proof motors, etc.
When the high-viscosity rotor pump has such problems, stop its operation in time. For example, high-viscosity rotor pumps have abnormal noise, vibration, oil seal leakage, flow and pressure drop, etc., so it is necessary to strictly control the quality of High viscosity gear pumps. Among some professional manufacturers, in terms of machining, whether it is casting or steel, there are CNC machining centers, and their fineness and aesthetics have reached a reasonable level. Especially in the selection of tooth shape, the compound of arc and sine curve is selected, which greatly improves the mechanical efficiency of the pump. Improvements in this area greatly reduce the noise and vibration of high-viscosity rotor pumps and increase the service life of high-viscosity rotor pumps. In terms of heat treatment of overcurrent parts, whether it is ordinary 45-gauge steel or special stainless steel, heat treatment procedures must be carried out to carry out high-frequency nitriding to increase the hardness and wear resistance of the gears, thereby increasing the service life of the high-viscosity rotor pump. In the assembly of the pump, the parts are cleaned by a special large-scale washing machine for half an hour to ensure the cleanliness of the parts. After assembly and molding, a high-intensity test of at least two hours is required. Only qualified products can enter the steps of external sales.
