1. When connecting the pump to the motor’s output shaft, it is necessary to first level each component separately and ensure that they are coaxial before installing the coupling; otherwise, it may cause damage to the machinery. 2. Since this pump is a constant-volume pump with a fixed displacement per rotation, if it continues to operate while the previous process stops working for some reason, the pressure inside the pump will increase indefinitely, eventually leading to issues such as seal leakage and damage to the mechanical components. Therefore, effective preventive measures must be taken. Example 1: Interlocking should be established with the upstream and downstream processes; when those processes stop, the pump should also stop operating simultaneously. Example 2: A safety valve and an overpressure relief system can be installed in the output pipeline to automatically relieve pressure in case of overpressure. 3. If control valves are to be installed on the pump, they should only be placed on the inlet pipeline of the pump; control valves should not be installed on the outlet pipeline, as this can easily lead to overpressure due to errors. After all installations are complete, a thorough inspection should be carried out, including checking the tightness of the components and the electrical connections. Then, turn the pump by hand 3 to 5 times to listen for any signs of jamming or looseness, until it operates normally. After that, conduct a power-on test run; if any abnormalities are detected, stop the work for repairs. The pump can only be put into use once everything is functioning properly. 1. Before starting the pump: First, check whether all the components of the pump are in good condition and whether all the valves on the inlet and outlet pipelines are open. In short, it is necessary to ensure that the components are intact and that the pipelines are unobstructed. 2. When starting the pump: it is necessary to allow the equipment in the next process to start operating first, before the pump itself can be started. 3. During operation, it is necessary to constantly check whether the operations are proceeding normally. If phenomena such as flow interruption before the pump or blockage after the pump are detected, the machine should be stopped immediately; it can be restarted only after the fault has been resolved. 4. When all operations along the line are to be stopped, the shutdown should be carried out in sequence according to the established procedure; that is, the pump should be stopped first, and then the related equipment following it. For any mechanical equipment, the quality of regular maintenance work not only reflects whether the production is running smoothly, but more importantly, it has a direct impact on the service life of the equipment. This is true even for pumps. Therefore, it is necessary to pay attention to the following aspects of maintenance work. 1. Seals for pumps are divided into static seals and dynamic seals. For the seals used to secure static components (see Figure 1, component 3), it is important that the surface be free of scratches or damage; otherwise, this will directly affect the sealing performance ； Regarding the moving part seal, it is subject to various factors such as pressure levels, corrosion from the medium being transported, and wear caused by particles in the medium (see Figure 1, component 2); any carelessness can very likely lead to leaks. Once the product leaks, the machine should be stopped immediately for maintenance; it should be wiped clean with soft, clean cotton cloth and coated with a layer of glycerin. After reassembly, it should be tested by hand before being put back into use. If repair is not possible, a new part should be replaced. 2. Lubrication components: Good lubrication conditions must be maintained for the drive gears and rolling bearings of this pump (refer to components 15, 11, and 1 in Figure 1). It is necessary to regularly check the oil level in the gears, ensure an adequate supply of lubricating oil, and maintain the purity and cleanliness of the oil; the oil should be replaced periodically, every six months or one year. 3. Electrical system: Devices that can damage insulation shall not be stored around electrical equipment. At the same time, electrical equipment must be kept operating in a dry environment. If it is unavoidable, moisture-proof measures should be installed. 4. Routine maintenance: Whenever the pump is not in use, an appropriate cleaning agent is selected based on the properties of the material being transported, to thoroughly clean the pump. Finally, it must be rinsed with clean water to ensure that the pump remains clean and hygienic.
