/Cutting type non-clogging submersible sewage pump product features
/Type high efficiency and no Clogging sewage pump, this electric pump is not afraid of clogging, has significant energy saving, reliable operation, and easy maintenance. It better solves the problem that the thick slurry pump cannot pump heavy particles and the sewage pump is easy to block. The submersible sewage pump also uses the most advanced mechanical seal in the country, with a sealing life of more than 1 hour. The pump shaft and fastening screws are all made of high-strength materials with good corrosion resistance. It is equipped with a motor leakage protector during operation to prevent leakage and short circuit. , phase failure plays a protective role and does not require special supervision. It is indeed an ideal equipment for pumping slurry containing particulate impurities, short fibers and slag in various industries.
The mass temperature must not exceed ℃ during use. The average mass weight does not exceed kilograms per cubic meter. The value of pumped liquid is ~.
During long-term operation, the part of the motor allowed to be exposed to the liquid surface does not exceed the height /.
Type sewage submersible sewage pump (hereinafter referred to as the electric pump) is a new type of water supply and drainage equipment developed by our factory's technicians on the basis of ordinary clean water submersible electric pumps. It is mainly used to discharge domestic wastewater, sewage, and human waste. Feces and suspended solids and non-corrosive media containing short fiber paper scraps, sawdust, starch, sand, gravel particles, etc. The temperature of the pumped liquid does not exceed ℃, and the density does not exceed / value~. This submersible sewage pump adopts double-end mechanical seals and a swirling impeller. The impeller is made of stainless steel, is wear-resistant, non-clogging, non-winding, and has the advantages of small size, compact structure, and easy portability.
The sewage submersible sewage pump (hereinafter referred to as the electric pump) is a submersible electric pump with a built-in pump structure. It is currently the most ideal machine for emergency drainage on narrow working surfaces and small sites. It has small size and weight. It has the advantages of light weight, easy movement, high efficiency, good sealing performance and compact structure. The temperature of the pumped liquid does not exceed ℃ and the density does not exceed /, value~.

/Cutting type non-blocking submersible sewage pump product use
/Type cutting type submersible sewage pump is suitable for pumping slurry water, pulp, short fiber, starch, gravel particles, non-corrosive Sexual medium, especially suitable for liquids containing more particles. It is suitable for sewage treatment in large and medium-sized enterprises, water plants, urban sewage treatment and subways, civil air defense projects, environmental protection systems and fish ponds, chicken farms, pig farms, etc. Ideal equipment for various breeding industries and flood control. Note that the main performance and data are the same as the internal structure except that it does not have a cutting device.
The / type sewage pump is suitable for the discharge of waste water from the basements of various high-rise buildings, civil air defense projects, hotels and subways, etc.
Pumping slurry water at engineering foundation construction construction sites, puddles, etc.
It is suitable for pumping slag slurry in food factories, paper mills, breweries, cement factories and other factories and mining enterprises, especially for Jinkuang and ceramic factories to pump glaze slurry.
Chicken farms, pig farms, various poultry and livestock farms, and fish ponds return to farmland for irrigation and drainage.
The / type cutting submersible sewage pump is especially suitable for narrow working surfaces such as shipbuilding, communications, shipping, and basements, and for excavation of ponds to dredge rivers, especially for individual food processing plants, individual breeding sites, drilling industries, and water accumulation. Used in pit wells, paper mills and paint factories.

/Precautions for use of type belt cutting submersible sewage pump
Before using the electric pump, you must first check whether the cable is damaged. When transporting and installing the water pump, the cutting iron may pull or damage the cable to prevent the cable from being pulled or damaged. Water leakage caused accidents after rupture. If the cable is hard to crack, the cable should be replaced immediately. And use a megohmmeter to check whether the insulation resistance of the electric pump is normal (the insulation resistance must not be less than megohms). Recognize the grounding wire (the grounding wire is usually yellow and green or connected with a grounding mark) and connect the grounding wire according to the prescribed procedures. (The grounding wire of our factory is equipped with a grounding mark).
Choose a suitable protector (such as leakage protector, air switch, phase failure overcurrent protector, etc.) and do not connect directly with a knife switch.
Connect the power cord according to the standard, test the power supply, check whether the electric pump is operating normally, and determine whether the steering is correct. If the steering is incorrect, just swap any two of the three power cords (note that the running time cannot exceed Half a minute).
Install the water outlet joint and water outlet hose (or tie the iron pipe with a rope on the handle of the electric pump (cables must not be used to replace the hanging rope). Put the electric pump into the liquid book to be pumped, and connect it. Just turn on the power and you can use it.
In order to ensure personal safety, when the electric pump is connected to power, it is strictly prohibited to install and launch water near the electric pump (such as moving or inspecting, troubleshooting, etc.) or touching the electric pump in case of power outage. Accidents may occur due to leakage of electricity in the pump!
It is strictly prohibited to run the entire electric pump above the water for long periods of time (or for short periods of time). The electric pump should not be started and stopped too frequently to prevent the motor from overheating and damage
Long-term pumping of liquids with high sand content For the flow-passing parts of the sewage pump with cutting device, it is recommended to use our cyclonic sewage submersible electric pump product.
If it is found that the sewage pump with cutting device does not rotate when it is running, In case of abnormal phenomena such as protector tripping and fuse blowing, the power supply should be cut off immediately and check whether there is any problem with the wiring of the power protector. If these external devices are normal, it may be that the electric pump is faulty. It should be continued to be used to avoid accidents!

/Repair and maintenance of type belt cutting submersible sewage pump
The electric pump should be managed and used by dedicated personnel, and the relationship between the electric pump winding and the casing should be checked regularly. Whether the insulation resistance between the stators is normal and must not be lower than ohms, otherwise the stator must be removed and dried, and the stator can be used only after the insulation resistance rises.
After each use, especially for thicker and more viscous slurries, the stator should be placed Run it in clean water for a few minutes before storing it.
After every ~ hours of use of the electric pump, open the waist oil hole screw and replenish it with pure engine oil, and use a mechanical seal to maintain good lubrication. If a large amount of water is found in the oil chamber, it means The mechanical seal has failed and should be replaced.
After the electric pump is started, if it is found that the flow is insufficient or the head cannot reach the specified value (unless the pipeline resistance is large or blocked), it may be that the direction of rotation is reversed. At this time, the power should be disconnected and the After any two of the three phase wires of the cable are exchanged with each other, connect the new ones before starting.
After the electric pump is disassembled and repaired, the sealing performance must be checked by a tight test.
Head and electric pump Separate and place them in a crate. Please install the elbow on the electric pump. If the electric pump is connected to the pipe, there is no need to install an elbow.
