Havana QJ submersible pumpWhat is your design theory

　　 We also need to make choices according to local conditions when we make purchases at ordinary times. For example, the head of the centrifugal pump itself is relatively high, but its water output is not very large when it is used, Ritter pump will provide you with high-quality slurry pump products; New progress in submersible slurry pump technology in recent years The diving depth has increased from meters to meters!Havana ,　　The working principle of the self-priming pump is to fill the pump casing with water (or there is water in the pump casing itself) before the pump is started. After startup, the impeller rotates at a high speed to make the water in the impeller channel flow to the volute. At this time, a vacuum is formed at the inlet to open the water inlet check valve. The air in the suction pipe enters the pump and　　 One frequency converter with one slurry pump is adopted for installation. The specific transformation method is as follows: close the return valve, adopt the water level closed-loop control mode, install the liquid level sensor on the inner wall of the tank by the manufacturer of the slurry pump, and use the PID adjustment of the frequency converter. WhenDilbeek,　　After meters, the sealing of the equipment can not bear the water pressure at this depth.　　If there are sundries blocked, the pump will not be filled with water. When this happens again, and check the impeller. In case of damage or aging, it needs to be replaced in time,　　The whole packing body, including the packing gland, packing ring and packing needs to be disassembled; Submersible slurry pump Disassemble the o-seal ring, shaft sleeve, balance disc and key on the shaft in turn, and then the discharge section includes the last stage guide vane

　　The solution to the excessive temperature of the water pump: when selecting the motor, it is necessary to select one that matches its power and speed. In addition, the cooling fan should be installed on the main shaft. It is also possible to appropriately increase the number of fan blades, but pay attention to adjusting the vacuum pump　　Vertical pipeline centrifugal pump is a kind of pipeline centrifugal pump with vertical structure. There are many models of this pump. The common one is ISG pipeline centrifugal pump. This pump is also very widely used. It is often used in industrial and urban water supply and drainage, and pressurized water supply in high-rise buildings. And in the　　Avoid airborne sound transmission; Ensure the airtightness of machine room doors and windows. The water pump is equipped with a sound proof cover,Havana Fire deep well pump, and an exhaust fan is added inside the cover to ensure the ventilation of the equipment. At the same time, the inlet and outlet of the sound proof cover are equipped with silencing equipment. A vibration isolation platform is installed at the bottom of the water pump for foundation vibration reduction to isolate the vibration generated during the operation of the water pumpWhere is it,　　 First, screw down the bolts on the side bearing pressure cap, and then remove the nuts used for the connection between the three parts: discharge section, stuffing box body and bearing body; Then screw off the round nut on the shaft, bearing gland and retaining sleeve　　Fourth, model selection parameters: outlet diameter flow,Havana WQ submersible sewage pump, dust, motor power, impeller speed, pumping rate, maximum particle and weight.　　Is called cavitation phenomenon.

　　First, the reason for the motor body: the wrong connection will make the temperature rise rapidly when the equipment is used; In addition, there may be some phase to phase short circuits between stator windings, so when the situation is relatively minor, the motor is only in local placesProfessional is king,　　 fold the three layers in half with self-adhesive butyl tape and gradually extend to the outside of the core. When winding, the tape shall be stretched twice and then the three layers shall be folded in half with PVC tape to ensure that the winding part is not less than mm,Havana Submersible sewage pump, and the positions of the three joints shall be staggered for a certain distance in order to prevent short circuit.　　 After the electric pump has been used for many times, it is necessary to put the electric pump into clean water and run it for several minutes to prevent sediment in the pump and ensure the cleanness of the electric pump.　　The vertical sand pump is generally a submersible slurry pump. Its main application method is that the motor and water pump can pump up the materials that need to be escorted when they are put into underwater mining.Havana ,　　So it is called: submersible slurry pump.　　 Another possibility is that the gas is sucked in when the pump is in use.　　When in use, it can drive the impeller to rotate so as to drive it to flow.
