With water, you can start working.　　 First remove the pump from the engine.Jumley,　　If the flow exceeds QD, which will seriously affect the service life of the pump. Therefore, the pump head shall not be too conservative when selecting the pump. It shall be as close to the actual head of the pipeline as possible. Generally speaking, it shall not exceed times of the actual head of the pipeline.　　When using the sand 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 avoidGressier,　　 First of all, let&#;s understand the causes of insufficient liquid supply: If the liquid level stored in the circulating liquid storage tank is lower than %, then insufficient liquid supply will occur when it is in use. Or the pump adds too much lubricating oil, which leads to accumulation　　Function of shaft seal of submersible slurry pump: the main of shaft seal is to prevent high-pressure liquid from leaking out of the pump and prevent air from entering the pump.　　Whether the pump is evacuated or overflowed, etc.,JumleyScrew deep well pump, and handle it at any time.

　　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.　　Correct the main shaft of the water pump and adjust the position of the water pump and the motor relatively.　　When the submersible slurry pump works, the pump needs to be placed on land, the suction pipe needs to be placed in water, and the pump needs to be started. Due to special structural requirements, when the slurry pump motor is submerged in the water the slurry pump and submerged slurry circulating pump need to be placed above the water surface, otherwise the motor will fall into the waterCreate brilliance　　 Precautions for disassembly of submersible slurry pump Before disassembling the filter press, make sure that the liquid in the submersible slurry pump is completely discharged. If the rotor is disassembled, drain the lubricating oil in the rotor bearing housing. If the newly added oil is stored, it should continue to be used after maintenance. Do not dump it directly　　About %), and motor power p=i × U indicates that high power and current will increase.　　 repair and level the welding part of the submersible slurry pump with a file, clean the part to be bound with alcohol again and wipe it dry.

　　Superior, complete protection s,JumleySelf priming slurry pump wholesale, reasonable structure, convenient installation and high cost performance. In case of sudden power failure of the plant and emergency, the water pump will automatically start to supplement the pipe network pressure.agent,　　Some impurities will entangle the impeller, so generally, the open impeller will be used, so there is no need to worry about getting stuck in the process of transporting sewage.　　Self priming refers to the process of sucking water from low to the pump cavity when there is no water (empty pipe) in the inlet pipeline (verb, self priming is an action and a process). Only the self-priming pump can have the self-priming .　　Yes, summer is the peak sales season. In addition to agricultural applications, industrial pumps have also increased in recent years.Jumley,　　 Next, you can place abrasive cloth on the glass or dry wood, if the thrust rubber water seal is used, when　　Submersible pump is a common water lifting equipment for deep wells. During operation, the whole machine intrudes into the water to extract water from the underground to the surface. It is commonly used for domestic water, mine rescue, industrial cooling, farmland irrigation,JumleyCirculating hot water pipeline pump, seawater lifting, ship load adjustment, landscape fountains, etc. Submersible pump is generally divided into clean water submersible　　 It may be that the motor power of the water pump is too large, the working current is too large, and the heat generation is too large, resulting in the high temperature of the vacuum pump.
