　　 there is also a simple method to measure the vibration frequency of the pump by vibration method. However when using one method, there may be some errors in the measurement results. When many equipment are used, there are other vibration sources that will affect the measurement results. Therefore, in fact, it is mainlyWelcome to inquire,　　 bind the exposed copper wire to the cable core evenly, heat it with an electric iron, and infiltrate tin evenly.　　 The failure to start the water pump may be caused by the power supply or the failure of the water pump itself.　　What stands out is the sealing of the container. The seal is easy to install and maintain, stable and reliable,HerazdanSubmersible non clogging slurry pump, but the price is quite expensive.Herazdan,　　Moreover, the leaked flammable, explosive and toxic liquid will cause fire, explosion and poisoning, and the consequences will be unimaginable.　　The pump can often be selected according to the specific requirements of lift, flow and liquid delivery. The flow range of the delivered liquid is - L / s, the pressure range is .- MPa, and the diesel engine speed range is - rpm. Features: water pump, high automation and performance　　Generally speaking, if the problem is serious, you must not adjust it at will. At this time, you should find a professional

　　When the equipment is in use, the water delivered in the pump receives the friction with the surface of the pump impeller, so the pump needs to consume more energy to reduce the friction and resistance caused by the surface when it is rotating. Water will slowly overcome it as it flows　　 confirm whether the pressure capacity of the pipeline meets the requirements, and conduct hydrostatic test if necessary.Ijimiyasin,　　 Check and replace accessories regularly: check cables,IjimiyasinVertical heavy-duty slurry pump, motor insulation and screws at least once a year. If it is damaged, it should be replaced in time.　　 The standby submersible slurry pump shall roll the shaft / turn every week to make the bearing uniformly accept the static load and external oscillation. The building structure in the water pump room shall be reconstructed. Sound absorbing and isolating plates shall be installed around the wall and on the top of the machine room and fixed with light steel keel; The connecting holes between the machine room and other rooms are tightly blocked,Kahriz, so it seems that many regions have good effects when using it.　　In fact, the impeller clearance of submersible slurry pump is not adjustable for all types of pump, but it is adjustable. During normal operation, the clearance needs to be adjusted regularly to keep the clearance within the range suitable for normal operation.　　 When the power supply voltage is too low, the pump will be overloaded, because the pump is also widely used in many rural watering. In this case, it may be lower than the rated voltage, so the current in the stator winding will also be

　　Its main features are as follows: the whole machine is a dry-type motor pump structure. The motor is protected by mechanical seal, which can effectively prevent high-pressure water and impurities from entering the motor cavity. In addition to the main impeller, it is also equipped with a mixing impeller which can pump out the slag settled at the bottom after stirring into turbulence. impeller　　Submersible sewage pumps are divided into xwq (cutting submersible sewage pump), jywq (automatic mixing sewage pump) and other series according to their s. One of the most commonly used is wq/qw (non clogging sewage pump) wq/qw (non clogging sewage pump), which adopts runner type impeller and generally has the features of energy saving, anti winding, non clogging and automatic　　Pump. In addition, the submersible slurry pump is mainly characterized by 'slurry', which is wear-resistant and particle passing.Quality assurance,　　 The bus voltage where the motor is located is V. Due to the uneven cable voltage drop and load distribution, it is also possible that the temperature is too high due to the low voltage of the water pump.　　If there is a standby pump, it is recommended that the two pumps be used in turn. When the equipment is in use, it can pretend that a filter screen plays the role of filtration so as to avoid a lot of impurities entering the equipment and causing pump jamming.　　If there is a standby pump, it can pretend that a filter screen plays the role of filtration it is recommended that the two pumps be used in turn. When the equipment is in use, so as to avoid a lot of impurities entering the equipment and causing pump jamming.

　　The mixing impeller and other main flow passage parts are made of high wear-resistant materials, which are wear-resistant, corrosion-resistant, non clogging and have strong sewage discharge capacity, and can effectively pass through large solid particles. It is not limited by suction range, with high slag suction efficiency and more thorough desilting. No auxiliary vacuum pump is required and the investment is lower. nothingInstallation materials,　　For example, in the market, for example, the sweeping pump, some of which have a depth of more than meters,IjimiyasinScrew deep well pump, it is not suitable to use a vertical slurry pump under such a working condition,IjimiyasinVertical slurry pump, industrial and domestic water supply and drainage, pressurization, industrial pipeline pressurized transmission, cleaning, refrigeration and air conditioning cycle, water supply equipment and boiler accessories. The operating temperature should be controlled below ℃.　　It needs to be replaced in case of damage, swelling and deformation, insufficient spring pressure, breakage, etc.Ijimiyasin,　　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.　　In the application of pumps, even the polluted water in cities needs to be purified. All these require its equipment to provide services for us. Without pumps, our basic survival is a problem.　　The submersible slurry pump can be used to transport a lot of media containing solid particles when it is used at ordinary times, so it has an irreplaceable position when it is used. What is its own structure when it is used.

　　Line direction pay attention to the direction of rotation. Then loosen the original compression nut of the bearing box of the slurry pump of the submersible pump tighten the adjusting screw of the bearing box evenly, and then move the rotor assembly towards the motor. Then it is necessary to check the clearance with a feeler gauge δ, When δ= A (. ~ mm　　 First of all, we need to choose equipment with formal certificates when making choices. We must avoid buying some obsolete or inferior products. And sometimes when the pump is in use,　　If this coating is removed over time in subsequent work, the owner of the stainless steel deep well pump can use another coating to resist corrosion and hot water.　　In this way, a smooth surface can be formed on the surface.Bururi,　　Causes: there is air or gas accumulation in the water inlet pipe of the pump, or the bottom valve is not closed tightly, the water supply is not satisfied, the packing of the vacuum pump leaks seriously, and the gate valve or flap valve is not closed tightly.　　Water flow into the bearing damages the bearing.　　It is an auxiliary means for some on-site monitoring.

　　 If the power cord is not well contacted, it will also lead to the burning of the motor.　　If you want to know how the slurry pump is classified, you must first understand what the slurry pump is: conceptually, it is a machine that increases the medium energy of the solid-liquid mixture through the centrifugal force generated by the rotation of the impeller, and a device that converts the electric energy into the kinetic energy and potential energy of the medium. and　　It can improve the mechanical efficiency to a certain extent. Moreover, the molecular structure of the coating itself has good compactness which can well isolate the air, water and other media from the pump impeller during use, and also reduce the corrosion and rust as much as possibleWelcome to inquire,　　If there are sundries blocked,VanazolUsed pipeline pump, the pump will not be filled with water. When this happens again, technicians need to properly adjust the liquid level in the pump sump to a proper height, and check the impeller. In case of damage or aging, it needs to be replaced in time,　　So it has a process of water diversion and exhaust. There are usually two ways to inject water into equipment. One is to directly inject water into the pump chamber, and the cavitation allowance of the device shall be greater than that of the pump. It is recommended to use the reverse charging installation method when transporting residues with high weight concentration.

　　Ensure that the service time will be extended when it is used. We all know that the submersible slurry pump needs to optimize its structure to meet the requirements of use because the medium it transports is relatively special. The structure has been optimized toLatest quotation, hydropower stations,VanazolSubmersible sewage pump, reservoirs, rivers, power plants, open caissons, mines and fish ponds.　　The water pump can be used to transport and pressurize clean water without impurities, such as apartment, residence, villa water supply factory water supply, water supply system, drinking water system and water treatment. In short, there are many uses.Vanazol,　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 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　　When using the sand pump,VanazolDrilling fluid slurry pump, be sure to pay attention to the steering divergence between the motor and the pump. The sand pump has an arrow on the pump to mark the main steering. After the power supply is connected, run the pump without load. Check whether the motor operates normally. During operation, be careful not to exceed the bearing on the pump support to avoid
