Selection of pipeline diameter: the selection of pipeline shall consider the one-time purchase cost, long-term operation cost and operation reliability.　　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 performanceKaramata,　　 whether there is oil　　 There may also be mechanical failure of the pump, such as serious damage to the bearing of the pump, so that the bore will be 'swept' when the stator and rotor rub against each other, or the impeller will be stuck due to impurities such as water and grass when the pump pumps waterTaounate,　　Promote the continuous expansion of the sales network group.　　The utility and durability of the utility model, the equipment must be regularly maintained and overhauled to avoid blockage. As the name suggests,KaramataWater well pipeline pump, the water pump is mainly used to transport water when it is used. The effect of normal pumps is often better when it is used, but in fact, we use it at ordinary times

　　The submersible slurry pump is a slurry pump which is connected with the motor and works under the water at the same time. Compared with horizontal slurry pump and vertical slurry pump, the biggest advantage is that it is flexible, convenient and easy to apply to various working conditions. The most important technical point of submersible slurry pump is the tightness between its motor and pump body Stability and reliability of seals.　　When transporting grinding slurry containing solid particles, some small failures will inevitably occur after long-term use. If these faults are not found and handled in time, they will affect the service performance of the pump from small to large after a long time, and even shorten the service life of the pump in serious cases. To avoid　　 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,KaramataVertical multistage centrifugal pipeline pump, and successively install the bearing inner race, bearing gland and retaining sleeveTrustworthy　　What should be paid attention to in the process? Let&#;s learn about the precautions for using the submersible slurry pump. When the equipment is in use, the pump itself generally needs to be placed on land for use, but its suction pipe needs to be placed in water　　 If there is no corresponding water leakage sensor, it is necessary to regularly maintain the submersible slurry pump and replace the seals.　　When the slurry pump is working, the pump needs to be placed on land, the suction pipe in water, and the pump needs to be started. Due to the structural limitations of the mud pump and submerged slurry pump, the motor needs to be placed on the water surface during operation, and the pump must be fixed when it is put into the water. Otherwise, the motor will fall into the water

　　The purpose is to inject liquid higher than . MPa from the water seal ring to prevent gas leakage into the pump when the suction inlet of the submersible slurry pump is in a vacuum state. When the water pressure in the pump is higher than . MPa the sealing fluid .-. MPa higher than the pressure in the pump can be injected to seal and reduce leakagehow,　　Where ρ—— Density of transmission medium liquid (kg/m; γ—— Gravity of medium liquid (n/m; H -- pump lift (m); Q - water pump flow (m/s); G - gravitational acceleration (m/s.　　The difference between the shaft power P and the effective power PE is the power loss in the pump, which is measured by the pump efficiency. The pump efficiency is the ratio of the effective power and the shaft power, it is necessary to use the fire control cabinet. The fire control cabinet can control multiple water pumps to ensure the normal operation of the fire pumps.　　In addition to the method, materials shall be selected comprehensively according to the nature of corrosive medium,KaramataScrew deep well pump, 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.Karamata,　　If the shaft seal is not properly selected it will not only require frequent maintenance during operation, but also leak a large amount of transmitted liquid.　　The motor is scrapped. Moreover, because the length of the long shaft is generally fixed, the installation and use of the pump is troublesome, and the application occasions are subject to many restrictions.　　It is not correct that it has no effect on us.
