whelkWater well pipeline pumpWhat are the unique performance advantages

the frequency of the frequency converter drops

　　When the water level reaches, and the slurry pump operates at a low speed. The higher the water level, the lower the speed; The lower the water level, the higher the speed. At the same time, the water level signal is transmitted to the control cabinet so that the operators can timely understand the liquid level. Through this control, the circulation in the slag slurry pool is basically unchanged　　 It is also possible that the fan blades of the pump are few and the air volume is insufficient,whelkZD slurry pump, resulting in poor heat dissipation effect.whelk, first, check whether the equipment operation noise is reasonable; second, check whether the alarm unit has leakage and overheating alarm signals; third, check whether the vibration of the guide rod is normal; fourth, the cause shall be yzed and reported in time.　　 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.Berlin,　　So it is called: submersible slurry pump.　　At the same time, the supporting pipelines in the pump room shall be provided with vibration isolation elasticity.　　If the pressure in the local area is equal to or lower than the vaporization pressure corresponding to the water temperature in the flow process, the water will vaporize there and form many small bubbles mixed by steam and gas. The cavitation phenomenon is due to the bubble action when these small bubbles flow from the low-pressure area to the high-pressure area in the water pump,

　　 When stopping the operation of the submersible slurry pump, close the cock of the vacuum gauge and pressure gauge and the gate valve on the water outlet pipeline and After that, cut off the power supply of the motor. If the temperature of the environment is low, the maximum temperature of the bearing shall not exceed ℃, and the quantity of calcium base grease used for lubricating oil bearing shall be the same as that of the bearing body　　It is worth noting that the vertical pipeline pump can work like the self-priming pump after it is equipped with a siphon device. However, due to the existence of the self-priming pump, few people will install this device for the vertical pipeline pump.　　 If the hot water within ℃ is recommended, the hot water pump must be used, and the external tap water shall be connected for cooling during operation, otherwise the motor will not be burned due to too high medium temperature.offer,whelkVertical slurry pump,　　 The pump body (can not) bear the pressure from the outlet pipeline system. The standby pump in the warehouse should rotate (/ times a week to make the shaft bear the load and external vibration evenly. The belt CR drive is that the motor is on the (right) side of the pump from the inlet of the pump.　　During adjustment, firstly loosen the support cover, then compress the nut, and then loosen the bearing seat. After adjusting the screw, materials shall be selected comprehensively according to the nature of corrosive medium, anti cavitation theory, corrosion mechanism of water pump and stress characteristics. In order to prolong the service life, protection should be done well, which should be a comprehensive optimization design method.

　　 add water with manual pump. Some pump owners have their own hand pumps. They can also buy or manufacture their own small hand pumps. The gate valve shall be installed at the water inlet. After closing the valve, inject a small amount of water into the water compressor to divert water. When the hand pump discharges water, it means that the pump is fullknowledge,　　 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 mainly　　 the water treatment equipment shall be selected according to times of the relatively large water consumption per hour.　　 determination of model: for water pump or pump with physical and chemical medium similar to water, it is necessary to go to the relevant product catalog or sample, and make correction according to the performance table or performance curve of the model to see whether the normal working point falls in the priority working area of the pump.whelk,　　The water pump can be used to transport and pressurize clean water without impurities, such as apartment, residence, villa water supply,whelkBooster pipeline pump, factory water supply, water supply system, drinking water system and water treatment. In short, there are many uses.　　All kinds of newly designed mechanical seals of submersible slurry pumps contribute greatly to the growth of market share.　　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
