  In order to ensure the demand for water and electricity for production and living, many units hotels and residential areas in various provinces and cities in China have purchased it and generators. Many enterprises have also purchased generators out of their own pockets in order not to delay production. Driven by this, it and the generator naturally become popular  The above is the correct sequence of impeller disassembly of submersible slurry pump. Because different types of pumps have some differences in structure, we also need to refer to the instructions when disassembling.Lauca   others  The premise of using this method is that the water gun must have sufficient flow during use, otherwise the effect of the submersible slurry pump may not be obvious.Dondo,  Water flow into the bearing damages the bearing.  Rate loss, so shaft power = effective power + lost power.   Then reinstall the equipment on the engine and install the rubber hose.

  Turn on the power supply type fool operation; It has a wide range of applications. In many cases, it belongs to a portable workstation, which can be brought wherever it is needed, because it does not need too many auxiliary facilities.  Operation management of screw pump Nemo pump (single screw pump) is a positive displacement pump, there is also a disadvantage of using the auxiliary impeller sealing system, that is, which is generally about %. However, as long as the planning is reasonable, this part of the lost flow can be reduced. The slurry pump is mainly applicable to electric power, metallurgy and coalTrustworthy,   The fan speed of the water pump is too low, and the air pressure and air volume are relatively small, so the heat cannot be dissipated.  The disc friction loss of the slurry pump impeller will decrease with the decrease of the impeller diameter, so that the pump efficiency of most low specific speed pumps will improve slightly after the impeller is cut. After cutting, keep the blades overlapped to a certain extent, and the degree of blade overlap will decrease with the addition of specific speed  According to the user&#;s requirements the motor can add a variety of protection devices such as water inflow detection and overheating, so that the product can operate safely for a long time under adverse working conditions.

  The solution to the excessive temperature of the water pump: when selecting the motor, it is necessary to select one that matches its power and speed. In addition,LaucaScrew deep well pump, the cooling fan should be installed on the main shaft. It is also possible to appropriately increase the number of fan blades, but pay attention to adjusting the vacuum pumpEconomic management,  Body. So that the pump can realize high concentration transmission without auxiliary devices. The unique sealing device can effectively balance the pressure inside and outside the oil chamber, so that the pressure at both ends of the mechanical seal can be kept balanced, which maximizes the reliable operation of the mechanical seal and greatly extends its service life  When assembling the motor and water pump departments below grade , firstly, tighten the nuts evenly between the water inlet joint and the contact plane from the upper part to the bearing seat, install the coupling, pump shaft, fixed studs and lock rings, fix the impeller and conical sleeve on the pump shaft with a damp cylinder, and install the guide housing and impeller  Different process requirements: the motor used in the vertical slurry pump is an ordinary vertical motor,LaucaUsed pipeline pump, which has no waterproof . The motor of the submersible slurry pump and the pump shaft are coaxial. The motor shall be waterproof and sealed. The motor and the pump body can invade underwater at the same time.Lauca, the blank operation point can be supplemented.  Troubleshooting: first increase the water pressure, then inject water into the pump body, and then start the pump. At the same time, 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.  In this way, a smooth surface can be formed on the surface.
