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　　It is an auxiliary means for some on-site monitoring.Bassett,　　The course can be stronger.　　 Inspection before installation: Check the specification,　　 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 submersible slurry pump usually relies on water cooling to dissipate heat. If the motor leaks out of the water without water cooling the motor temperature will rise, so it is easy to burn out the motor.　　The submersible slurry pump is developed to adapt to the increasingly complex working conditions and facilitate the use of users. Its use mode is more flexible. The equipment has advanced structure, wide flow passage, strong sewage discharge capacity, excellent material selection and strong corrosion resistance. Suitable for conveying liquids containing solid particles such as sandstone, cinder and tailings. So what are the requirements for its work? Let&#;s understand briefly.

　　There is a difference between submersible slurry pump and sewage pump. Although the media conveyed by the two are not pure water and other media, parallel belt drive, upper and lower belt drive, CV vertical belt drive, etc. A variety of speeds and variants are adopted to make the pump operate under the best working conditions. It has long service life and high operation efficiency, and can meet many kinds of harsh transportation conditions.　　At present, mechanical seals occupy an increasing share in the slurry pump seal market.How much is it,　　Function of shaft seal of submersible slurry pump: the main of shaft seal is to prevent high-pressure liquid from leaking out of the pump and prevent air from entering the pump.　When using the submersible slurry pump, the equipment may be burned out. The main reason for this phenomenon is improper operation. How should we prevent the burning out?　　 The gas inadvertently entered in the equipment is discharged and good sealing performance is ensured.

　　The input quantity is related to many factors such as the rotating speed of the submersible slurry pump, the bearing standard, the continuous working time the number of stops and starts of the pump, the surrounding environment and the working temperature. Therefore, it is necessary to gradually accumulate the experience and add smooth oil in a reasonable and timely manner.management,　　Compared with the vertical slurry pump, the application market is also larger. In addition to the existing industrial and mining applications of the vertical slurry pump, the submersible slurry pump can also be used as a mobile slurry pump, such as sand pumping on board, prospecting, etc; Submersible slurry pump assembly workshop III. what are the advantages of submersible slurry pump　　Use a V megohmmeter to measure the insulation resistance between the electric pump motor and the phase to ground, and the value shall not be less than megohm. Otherwise,BassettWQ submersible pump parameters, the stator winding of the motor shall be subject to monotonic treatment, long-term operation cost and operation reliability.Bassett,　　It is longer and saves production cost. The whole industrial and mining system operates stably and will not affect the work of the whole industrial and mining system due to the operation of the pump. When the rotating speed of the submersible slurry pump cannot be changed and the lift is higher than the required equipment lift,BassettSubmersible sewage pump, the cut impeller is usually used. The cut is　　With the continuous development of slurry pump technology, submersible slurry pump appears in response to market demand. It is especially suitable for the depth at which the vertical slurry pump cannot operate. The underwater part of the vertical slurry pump is generally not more than m,BassettCorrosive pipeline pump, and of course it can be more than. For example, the maximum design depth of our company&#;s underwater slurry pump can reach m, but such underwater depth is not the best operating depth of this kind of pump, so it will lead to the unreliability of the operation of the vertical slurry pump from time to time.　　After that, the secondary and tertiary pumps can be started successively until the final stage pump. After all the series pumps are started, the outlet valve of the final stage pump can be gradually opened. The speed of opening the valve should be controlled by the fact that the pump does not vibrate and the motor of any stage does not exceed the rated current.
