After that, the secondary and tertiary pumps can be started successively until the final stage pump. After all the series pumps are started,Samragd Pipeline pump, 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.　　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, and the gate valve or flap valve is not closed tightly.Samragd ,　　 The power line of the submersible sewage pump is relatively long, and the configured cable is relatively thin, so the voltage drop is too large and it is difficult to start the submersible pump. A larger cable is required. If the distance is long, the submersible pump should be close to the transformer.　　Second, the service life of the flow passage parts of the pump is relatively long, saving production costs.Siavonga,　　In addition to the method, materials shall be selected comprehensively according to the nature of corrosive medium, anti cavitation theory,Samragd Irrigation 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.　　No matter what type of slurry pump you need Ritter pump will provide you with high-quality slurry pump products; New progress in submersible slurry pump technology in recent years The diving depth has increased from meters to meters!　　Slurry pump Inappropriate model is selected when selecting the pump. In actual use, for example, the pump lift used is too high or too low, which will lead to overload,Samragd Deep well pump, so we are selecting the pump

　　What is the order.　　 Temperature control: an external temperature controller is used to turn on or off the pump according to the set temperature range. It is used in constant temperature, heat exchange system and other occasions requiring temperature control.　　 Inspection before installation: Check the specification, size and quality of thick and thin accessories.total cost,　　The water slurry pump is a widely used equipment. Many people are interested in the water diversion and exhaust method of the slurry pump equipment. Now let&#;s talk about the water diversion and exhaust method of the submersible slurry pump: the submersible slurry pump needs to pump out the water to form a vacuum, and then supply water,　　 It is also possible that the fan blades of the pump are few and the air volume is insufficient, resulting in poor heat dissipation effect.　　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.

　　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, which is measured by η Indicates.Where can I find it?,　　It is an auxiliary means of on-site monitoring. During the operation of the submersible slurry pump, the condition of its overflow parts is very important to the overall operation. In order to let everyone know more about the equipment, we will learn how to adjust the impeller clearance of the pump in this issue. I hope it will help you.　　 Realize centralized management. In the application of multiple fire pumps, the deployment of fire pumps may be decentralized, and the working environment of fire pumps is often complex, so it is very difficult to adopt manual management. cf fire control cabinet can realize centralized management of multiple fire pumps, with operation　　Promote the continuous expansion of the sales network group.Samragd ,　　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　　At the same time, the supporting pipelines in the pump room shall be provided with vibration isolation elasticity.　　Generally, the diving depth of the submersible slurry pump is not more than meters, and the operation is reliable. Why not more than meters? This is the crucial technical point of the submersible slurry pump, because the current sealing technology in China is more than meters, but because
