Troubleshooting: first increase the water pressure, then inject water into the pump body, and then start the pump. At the same time,General escovedo townSubmersible sewage pump, check whether the check valve is tight and whether the pipes and joints leak. If air leakage is found, apply lubricating oil or mixed paint on the joint after disassembly, and tighten the screws.　　Screw it down, and then remove the bearing inner race, shaft sleeve and retaining sleeve in turn.General escovedo town, etc.) and a check valve. The valve is used to regulate the operating point of the pump. The check valve can prevent the pump from reversing when the liquid flows back (the long shaft deep well pumps produced by our company are equipped with anti reversing check devices) and prevent the pump from being hit by water hammer　　We also need to limit the starting frequency and select appropriate thermal protection devices for use.Jona,　　Pump. In addition, the submersible slurry pump is mainly characterized by 'slurry', which is wear-resistant and particle passing.　　 First, screw down the bolts on the side bearing pressure cap, and then remove the nuts used for the connection between the three parts: discharge section, stuffing box body and bearing body; Then screw off the round nut on the shaft, and successively install the bearing inner race, bearing gland and retaining sleeve　　The water pump is not only the water supply for the city, but also the household water purifier used in our home. There is a with pump equipment to help us purify water. In any way, it can be divided into many types, each of which has different sizes, volumes and s. Therefore many people believe that

　　The use of water pumps for agricultural drainage and irrigation can improve the ability of agriculture to resist natural disasters, increase production and ensure income, and provide material conditions for agricultural mechanization and water conservancy.　　It can be done. For example, before the test run, the motor and the main pump are separated from the test in the positive and negative directions, including glue, the clearance between the impeller and the front guard plate must be adjusted regularly to keep it between (.-mm). In addition to monitoring the flow and pressure during the operation of the pump,General escovedo townCirculating hot water pipeline pump, the motor shall not exceed the rated current of the motor. Monitor oil seal and bearing at any timeinvestment,General escovedo townSubmersible sewage pump,　　It can also be used for cooling and lubrication. Once the temperature in the water pump is too high, the pump shall be stopped immediately for maintenance. Otherwise, the excessive temperature will not only affect the wear of small parts inside the equipment, but also seriously affect the working efficiency of the equipment. So what is the reason for the high temperature of the equipment　　Stability and reliability of seals between pump bodies.　　If the pump outputs more medium liquid, it will certainly do more work. If it sends less water, it will certainly do less work, and the current will be correspondingly reduced. Pump power (kw) = head (m) × Flow (m/s) × The gravity of the fluid (kg/m for water) divided by (power conversion factor) divided by the efficiency of the pump (about

　　 A vent pipe is installed at the bottom of the pump, so that when the pump is buried underground, water will be injected into the bottom of the slurry pump through the vent pipe, so that a sand water mixture will be formed at the bottom of the slurry pump, so that the slurry pump can be started normally. The advantage of this approach is that even ifInspection basis,　　After a certain value, water will also vaporize, which is called the vaporization pressure of water at this temperature.　　The sheath is divided into front sheath and rear sheath, which are made of natural rubber. The lining is made of high chromium alloy, so as to prolong the maintenance and replacement cycle and reduce the operation cost. The outlet of this series of pumps can be installed at angles　　 Impeller protection in order to ensure the operation of the submersible slurry pump, it is necessary to timely adjust the clearance between the impeller and the front guard plate. When adjusting the impeller clearance, first stop the pump, loosen the bolts pressing the bearing box, loosen the adjusting nuts, make the bearing components move forward, and roll the shaft by hand to press theGeneral escovedo town,　　 Protective packing of shaft seal the shaft seal pump shall regularly check the sealing water pressure and water volume, keep a small amount of cleaning water flowing along the shaft, regularly adjust the packing gland check the packing and regularly replace the packing. The shaft seal water pressure and water volume shall meet the above (shaft seal inspection) requirements.　　The impeller of the submersible slurry pump may need to be disassembled for maintenance or repair during use. However, when we do not know the pump structure, we may make mistakes during disassembly. Let&#;s take a look at the correct disassembly of the impeller　　 One frequency converter with one slurry pump is adopted for installation. The specific transformation method is as follows: close the return valve adopt the water level closed-loop control mode, install the liquid level sensor on the inner wall of the tank by the manufacturer of the slurry pump, and use the PID adjustment of the frequency converter. When
