Want to pump the normal operation, like to improve the service life of the pump, it should be on the pump maintenance, pay attention to the operation of the pump operation. Xiao Bian speaking inverter pump installation, maintenance and precautions. Frequency conversion pump First, the installation of variable frequency pump equipment 1. Equipment installation should choose a well-ventilated, dust-less, not wet site, the ambient humidity is -10 ℃ -40 ℃. Should be set outdoors in the rain, lightning and other facilities. 2. In order to facilitate the installation and maintenance of equipment and equipment, 70cm space should be left around the equipment, 1.5m space should be reserved at the manhole, and drains should be provided around the ground. 3. After the selected site, to deal with the foundation, with concrete pouring or brick masonry tank bearing seat. After the base is fully cured, the can is then lifted and stabilized. Then the equipment is fitted with accessories and the power is turned on. 4. Before the test, you should close the water supply valve, check the sealing valve conditions, not allowed to leak, after driving, should be running Notes Pump steering. When the pressure gauge pointer to the upper limit, the pump automatically stops. Open the water supply valve, you can normal water supply, for regular water supply, can choose to switch to the manual position. Second, the frequency conversion pump equipment maintenance 1. Frequency Pump Pump Unit should always check, regular maintenance and filling oil. Centrifugal pump and check valve If any water leakage is found, fasten the flange screws or replace the asbestos root in time, and check that the pump foot bolts can not be loosened to prevent damage to the machine. 2. Electrical automatic control system, should be waterproof, dustproof, often check the line insulation, the connection bolts are loose and the fuse intact and so on. The most external pressure gauge with transparent raw material package to prevent damage. 3. If the tank body is found peeled off, should be painted and maintained in time to extend the service life. Third, the frequency of pump operation precautions 1. Ball valve in the closed state, the body still exists within the pressurized fluid; 2. Before maintenance, lifting the pipeline pressure and the valve is in the open position; disconnect the power or gas source; the implementing agencies and The bracket off; 3. Must first identify the ball valve, the downstream pipe has been removed after the pressure has been removed to disassemble and disassemble; 4. decomposition and reassembly must be careful to prevent damage to the sealing surface of parts, especially non-metallic parts, remove the O Ring should use special tools; 5 flange bolts on the assembly must be symmetrical, step by step, evenly tightened.
