3Shanghai Jinshan District Sewage Pump Company
Product features of Shanghai Jinshan District submersible high-efficiency non-clogging sewage pump:
． It adopts a unique single-blade or double-blade impeller structure, which greatly improves the dirt passing capacity, and can effectively pass through fibrous substances twice the diameter of the pump and solid particles with a diameter of about 10 times the diameter of the pump.
． The mechanical seal adopts new hard and corrosion-resistant titanium tungsten material, which allows the pump to operate safely and continuously for more than hours.
3. The overall structure is compact, small in size, low in noise, significant in energy saving, and easy to maintain. There is no need to build a pump room and it can work when submerged in water, which greatly reduces the project cost.
． The pump's sealing oil chamber is equipped with a high-precision anti-interference water leakage detection sensor, and a thermal sensor is embedded in the stator winding to automatically protect the water pump motor.
． A fully automatic control cabinet can be equipped according to user needs to automatically protect the pump from water leakage, leakage overload and over-temperature, etc., improving the safety and reliability of the product
. The float switch can automatically control the starting and stopping of the pump according to the required liquid level change. It does not require special supervision and is extremely convenient to use. ． The series can be equipped with a double guide rail automatic coupling installation system according to user needs, which brings greater convenience to installation and maintenance, and people do not have to enter the sewage pit for this purpose.
． It can be used within the full lift without overloading the motor.
． There are two different installation methods, fixed automatic coupling installation system and mobile free installation system.
Main uses of Shanghai Jinshan District submersible high-efficiency non-clogging sewage pumps:
Series of non-clogging submersible sewage pumps are suitable for chemical industry, petroleum, pharmaceutical, mining, paper industry, cement plants, steel plants, power plants, coal Processing industry, as well as urban sewage treatment plant drainage system, municipal engineering, construction sites and other industries conveyor belts of granular sewage and dirt are also used to pump clean water and corrosive media.
Precautions for Shanghai Jinshan District submersible high-efficiency non-clog sewage pump:
Before using the pump, carefully check whether the cable is damaged, whether the fasteners are loose or fallen off, and whether the pump is transported, stored, and installed There is no deformation or damage in it.
.Use a megohmmeter to measure the insulation resistance between the same and the opposite ground of the electric pump motor. The value should not be lower than megohm. Otherwise, the stator winding of the motor should be dried. The temperature of the drying process is not allowed to exceed ℃.
3. This series of pumps can be installed in two types: fixed type and mobile type. When using fixed automatic installation, the chain cables should be inserted into two lifting eye screws or lifting plates (deviated from the pump outlet, and the connection should be parallel to the pump outlet) to lift the electric pump up and down. Slide down the rail evenly and slowly until the automatic coupling is in place. When using mobile installation, first cover the hose and use the chain rope to pass through the two lifting rings to lift the electric pump up and down. Be careful not to use the cable as a rope to avoid danger.
.The direction of rotation of the pump after it is connected is counterclockwise when viewed from the water inlet. If the electric pump is reversed, just swap the wiring positions of any two wires in the cable.
. The ground wire of the electric pump's casing must be connected strictly in accordance with relevant regulations. In order to ensure personal safety during use, it is strictly prohibited to install, operate or move the electric pump nearby when it is running, just in case. An accident occurs due to leakage of electricity from the electric pump.
.Electric pumps must be equipped with a fully automatic water pump control cabinet unless there are special circumstances. Do not directly connect to the power grid or use a knife switch to connect the power supply to ensure the normal operation of the electric pump.
. The electric pump must not be operated in a low-lift state for a long time (generally, the lift must not be lower than the rated lift). It is best to control the lift within the recommended range to prevent the electric pump from burning out the motor due to overload.
.Pumps without self-circulation cooling devices are strictly prohibited from being exposed to the water for long-term operation to prevent overheating and damage to the electric pump.
Shanghai Jinshan District submersible high-efficiency non-clog sewage pump maintenance and upkeep:
The electric pump should be managed and used by dedicated personnel, and the insulation resistance between the electric pump winding and the casing should be checked regularly to see if it is normal.
.After each use, especially for thicker and more viscous slurries, the electric pump should be placed in clean water and run for a few minutes to prevent sediments from leaving in the pump and ensure the cleanliness of the electric pump.
3. If the electric pump is not used for a long time, the electric pump should be taken out of the water and should not be immersed in water for a long time to reduce the chance of the motor stator winding getting damp and increase the service life of the electric pump.
After the electric pump is disassembled and repaired, the casing components must be inspected by an air tightness test to ensure that the motor seal is reliable.
The sealing ring between the impeller and the pump body has a sealing function. If the seal is damaged, it will directly affect the performance of the pump and should be replaced if necessary.
Shanghai Jinshan District submersible high-efficiency non-clogging sewage pump product introduction:
The non-clogging submersible sewage pump is a new generation pump successfully developed on the basis of the introduction of foreign advanced technology and combined with the use characteristics of domestic water pumps. This type of product has the characteristics of significant energy saving effect, anti-winding, no clogging, automatic installation and automatic control. It has a unique effect in discharging solid particles and long fiber waste.
This series of sewage pumps adopts a unique impeller structure and new mechanical seal, which can effectively deliver solid materials and long fibers. Compared with the traditional impeller, the impeller of this pump adopts the form of single flow channel or double flow channel. It is similar to an elbow with the same cross-section size. It has very good flow performance and is equipped with a reasonable volute, making the pump highly efficient. The impeller and impeller have undergone dynamic and static balance tests to ensure that the pump does not vibrate during operation.
Scope of application of Shanghai Jinshan District submersible high-efficiency non-clogging sewage pumps:
Series of non-clogging submersible sewage pumps are suitable for the discharge of severely polluted wastewater from factories and businesses, sewage drainage stations in main residential areas, and urban sewage treatment plants. Water distribution systems, civil air defense system drainage stations, water supply equipment in water plants, sewage discharge in hospitals and hotels, municipal engineering construction sites, mining supporting auxiliary machinery, rural biogas pools, farmland irrigation and other industries, conveyor belt granular sewage and dirt, It can also be used in clean water and weakly corrosive media.
