Sign in perhaps register 。

　　It can also be used for cooling and lubrication. Once the temperature in the water pump is too high, the pump shall be stopped immediately for maintenance. Otherwise, the excessive temperature will not only affect the wear of small parts inside the equipment, but also seriously affect the working efficiency of the equipment. So what is the reason for the high temperature of the equipment　　At the same time, the supporting pipelines in the pump room shall be provided with vibration isolation elasticity.Bevellen,　　 Packing shaft seal: the packing shaft seal is the most common seal, with simple structure, convenient maintenance and low price. However, the shaft seal water must be used. For the working conditions that are not suitable for the auxiliary impeller shaft seal, the packing shaft seal can be used.　　Second, the power used is not matched, so the motor temperature will be too high after long-term overload operation; In addition, frequent startup during use will also lead to fever,BevellenPipeline pump body, so IBytca,　　Submersible slurry pump In addition, the sewage pump is usually driven by a motor, which also requires some time og quantity when switching on and off, so in fact, it can be adjusted to a certain extent during use. The submersible slurry pump needs to use a line when in use　　The impeller of the submersible slurry pump may need to be disassembled for maintenance or repair during use. However, when we do not know the pump structure, we may make mistakes during disassembly. Let&#;s take a look at the correct disassembly of the impeller　　Submersible slurry pumps are mainly used in mining,BevellenPipeline pump, metallurgy, coal, environmental protection, electric power and other industries to transport corrosive solid particle slurry. For example in the field of chemical industry, corrosive mixed pastes of chemical crystals are transported. Electric ash removal, coal washing plant slurry transportation, etc. Submersible slurry pump blade

　　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.　　Operation, maintenance and upkeep During the operation of the electric pump,BevellenSmall deep well pump, always observe the current voltmeter and water flow, and strive to make the electric pump operate under the rated working condition.　　It can also be used for cooling and lubrication. Once the temperature in the water pump is too high, the pump shall be stopped immediately for maintenance. Otherwise, the excessive temperature will not only affect the wear of small parts inside the equipment, but also seriously affect the working efficiency of the equipment. So what is the reason for the high temperature of the equipmentProject scope,　　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, accurate and reasonable selection is very important. In order to select the pump reasonably and correctly which is measured by η Indicates.　　Do not exceed the rated current.　　Discount. In order to meet the needs of industrial production and make the submersible pump to achieve the ideal use effect, the following aspects need to be considered: Selection of shaft seal form: shaft seal of submersible slurry pump

　　Submersible slurry pump is a kind of pump used in mines. Do you know the effect and form of its shaft seal? Let&#;s have a look.how,　　The solution to the excessive temperature of the water pump: when selecting the motor, the cooling fan should be installed on the main shaft. It is also possible to appropriately increase the number of fan blades, 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　　With the arrival of midsummer and the intensification of the contradiction between supply and demand of kerosene, the power supply across the country has been tense again, which has driven the hot sale of it and generators in the phase II market. According to relevant data, in the second half of the year, there is still a large gap after China&#;s power balance.Bevellen,　　After that, the secondary and tertiary pumps can be started successively until the final stage pump. After all the series pumps are started, 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.　　About %), and motor power p=i × U indicates that high power and current will increase.　　 the water pipe shall be provided with a gate valve to regulate the pump working point. The valve shall be installed as close to the pump outlet as possible. The pump unit greater than meters shall be provided with a check valve at the pump outlet. In case of sudden shutdown, it is necessary to prevent damage to flow passage components caused by water hammer.
