QW (WQ) submersible non blocking sewage pump needs to be equipped with a fully active water pump control cabinet under no exceptional conditions. Do not directly connect the power grid or use the knife switch to connect the power supply to ensure the normal operation of the electric pump.
4 The treatment methods are as follows:Check whether the current and voltage of the water pump are abnormal at this time. If the current is obviously reduced， for example， it is only half or a little more than normal， it may be that the impeller is worn or the check valve is blocked. If the current is not much different from the normal current， it can be
pCharlotte The equipment is integrated with the oil cooler with compact layout. The water pump meets the modular and integrated design requirements of diesel engine parts. The joint surface with oil cooler adopts rubber sealing method， which has good sealing effect. Submersible slurry pump is a kind of solid-liquid mixing medium with the help of centrifugal force
If the flow exceeds QD，S.SH type pump cavitation and vibration will occur，ColumbusQJ submersible pumpDetailed explanation of type and working principle 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.
GNakhon Sawan What faults will the water pump control cabinet often encounter in use? The water pump cannot work: cause: a. the power supply is not connected or the output phase of the control cabinet is missing; b. The water pump has been burnt out， and the water pump can not supply water: cause: A. whether there is water in the pool; b. Whether there is gas in the pump body that is not discharged; c. Inlet and outlet water
Ra Improve work efficiency. The traditional manual start-up of fire pump is difficult to operate， complex and dangerous. Manually starting the fire pump can only be operated one by one. If there are a large number of fire pumps， it will take a lot of time， and its work efficiency is extremely low. cf
panning for gold and extracting iron sand.
Structural features of horizontal slurry pump:The ah， HH and L-type slurry pumps at the pump head are of double pump shell structure， that is，S.SH type pump the pump body and cover are equipped with replaceable wear-resistant metal lining， and the flow passage components such as impeller， sheath and guard plate are made of high chromium wear-resistant metal. The pump body and cover are made of grey cast iron according to the working pressure
f 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， it means that the pump is full
S The personnel on duty for daily inspection and maintenance of the submersible pump shall make one listening， two looking， three touching and four recording.
Hknowledge for new or replaced deep well submersible pumps， after hours of use check whether the seal is good. In the future， check it once a month. At the same time， check whether the shielding sleeve between the motor rotor and stator is well sealed. Try to reduce the number of starts in use.
bQ In order to maintain the original treated water volume without increasing the number of water pumps， the liquid level in the storage tank can be increased by adjusting the floating ball in the liquid tank. After the liquid level in the storage tank is increased，S.SH type pump the he QE curve of the device must move to the right. At this time， the head at the intersection of the two curves becomes smaller and the flow remains
On the basis，ColumbusQJ submersible pumpDetailed explanation of type and working principle according to the type selection requirements of different transmission media and temperatures， IHG vertical chemical centrifugal pump， YG vertical pipeline centrifugal pump， ihgb vertical explosion-proof stainless steel pipeline centrifugal pump and isgb explosion-proof pipe
In order to meet the use requirements of slurry pumps in different industrial fields and working conditions， we have continuously carried out research， development and improvement， so that we have different series， each series has a variety of specifications and models，Submersible slurry pump, WQ submersible sewage pump, submersible sewage pump, deep well pump, pipeline pump, AH slurry pump, QJ submersible pump, HH slurry pump - Hebei Xinjiasheng Pump Industry Co., Ltd and different series of products have different performance and s. Let&#;s learn about it below
Latest quotationk Check the three-phase current with an ammeter on the control panel. If the phase power supply is found to be insufficient， the power supply of the submersible pump shall be turned off immediately. Check whether the cable connector， connection point and power switch contact are in poor contact and whether they are the main line. Check whether the circuit wiring is broken or loose or whether the fuse is damaged or burnt out
J The Tao part also consumes part of it.

aCharlotte There are main reasons why the submersible pump is "sick".The rotation direction of the motor is wrong: please ensure that the rotation direction of the motor is correct before using the submersible sewage pump. Even if water is produced by reverse rotation， the output of water is small and the current is large. Direction rotation will cause irreversible damage to the motor winding
aM Steam will produce air bags， which are harmful to water and seriously damage the vacuum suction. In order to immediately empty the pipe， avoid balloon accumulation. The suction pipe shall be a steep slope rising to the direction of water flow， rather than an immediate vertical rise， generally exceeding .， which should be the height of the top water pipe along the pump inlet
First of all， the slurry pump is divided into three categories from the installation method: horizontal slurry pump， vertical slurry pump， submersible slurry pump horizontal slurry pump: also known as dry installation slurry pump， because it is installed on the ground and the surface of the pump body cannot contact the slurry， it is called dry installation. When this type of pump is installed，
