The ball or bearing of the motor is damaged.
2 the float switch can automatically control the start and stop of the pump according to the required liquid level change， without the need for special personnel， which is very convenient to use.
vMesa 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.
number of lifting pipes
XYuanshan The rotation direction of the impeller shall not be reversed to damage the pump body.
Ih transmission device type (gearbox transmission， flat belt transmission，Submersible slurry pump V-belt transmission)
Consider the vertical separation level of the tail equipment. The water pump control cabinet has a variety of protection s and complete status display，SacramentoZD slurry pumpThe manufacturer shall pay attention to its maintenance such as overload， short circuit， phase loss protection， pump body water leakage， motor over temperature and electric leakage， as well as single pump and multi pump control working modes， a variety of main and standby pump switching modes and various
The quality of the substitutes produced is not up to the standard， and the price of imported spare parts is expensive; Moreover in the subsequent sludge treatment unit， the flow passage parts of the centrifugal dehydrator are more sensitive to sand particles. Therefore，Submersible slurry pump sand particles in the conveying medium shall be minimized.
t For example， in the market， for example， the sweeping pump， some of which have a depth of more than meters， it is not suitable to use a vertical slurry pump under such a working condition， but it is extremely easy to use a submersible slurry pump.
Q If it can be started and operated with lubricating water， or other types of bearings (such as polymer bearings) can be used according to the design or contract requirements.
Wbuild touch method: touch the pump to monitor the changes of temperature， vibration and clearance， so as to judge whether the pump is faulty.
mD Vertical height from water outlet center of pump base to flow destination (m)
Actually，Submersible slurry pump you dont have to worry about this. First of all， stainless steel has very strong anti-corrosion ability compared with products that are easy to rust. When many friends buy stainless steel deep well pumps，SacramentoZD slurry pumpThe manufacturer shall pay attention to its maintenance their manufacturers will apply a thin anti-corrosion coating on the outer layer of the equipment according to the needs of consumers. as
Or nodular cast iron， vertically split， bolted. The pump body is connected with the bracket with bolts. The discharge outlet of the pump can be rotated and installed at intervals of ℃ and eight angles as required.
Production departmentp 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.
O The working properties of the two pumps are also different. Because the sewage pump is driven by a motor， it generally has good voltage impact resistance. The submersible pump is of the type of quick opening and quick closing， so it usually uses some small Flow and small pressure.
For the pipeline pump in the workshop， it is necessary to consider whether the pipeline pump is worn to a certain extent due to inadequate maintenance， but the performance of the pipeline pump is degraded.In case of abnormal water absorption during installation check the motor during installation，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 check the motor wiring and speed， so it is called pipeline pump. It is defined and named according to the special appearance of the pump. If it is named according to the principle， the pipeline pump is a special structure
sH The lift of deep well pump is calculated according to the following formula
After the submersible slurry pump is connected， it is necessary to shake the insulation resistance and observe its change when going down the well to prevent the insulation skin of the cable from being damaged by the well wall. If the insulation is found to drop rapidly below . megohm， the device shall be lifted to find out the cause. Because the submersible slurry pump is often used
