Product Description:

Production Introduction:
WQ blockage-free sewage submersible pump(hereinafter as pump) is untegrative motor and pump. Which is manufactured based on absorbing domestic and foreignadvanced technology and advantages. Impeller, designed with hydraulic model and made by precision casting, has the advantages of energy-saving, anti-winding and non-clogging,etc. At the same time, the pumps have a unique effect in the carriage of solid particles and long fibers garbage. Single or dual impeller structure ensures the pump has the higher efficiency when it has bigger flow. So this king of pump is a ideal drainage pumps for industries and cities.

Q:Is the flow meter in front of the pump or after the pump?
After the pump, the reasons are as follows, before the pump, you pump fluid through the pump will produce negative pressure in front of the pump, negative pressure on the flow of the life of the impact, the pump will not, Suzhou first Chi meter
Q:Attention should be paid to the use of pumps?
1, pump shaft packing completely worn, it is necessary to add in time, if you continue to use the water pump will leak. The direct effect of this is the increased energy consumption of the motor, which will damage the impeller. 2, the use of pumps in the course of a strong vibration, then must stop to check the reasons, or the same will cause damage to the water pump. 3 gear pump valve Water Leakage, some will use the soil into the water pump inlet tube, the water washed in the end valve, this is indeed undesirable. Because when the dry soil into the inlet pipe, when the pump started working, these dry soil will enter the pump, which will damage the pump impeller and bearings, which shorten the service life of the pump. When the valve Water Leakage must take to repair, if it is serious that it is necessary to replace the new. 4 after the use of pumps must pay attention to maintenance, for example, when the pump is exhausted, we should put the water pump who put clean, it is best to remove the water pipe, and then rinse with water. 5 water pump on the tape should also be written down, and then always flush, and then light out to dry, do not put the tape in the dark damp place. Water pump tape must not be stained with oil, not to tape coated with some sticky things.
Q:How to adjust the flow of piston pump?
The oil pan with oil liquid through the suction port and the piston cylinder; from 180 degrees to 360 degrees, the piston cylinder volume decreases, so the oil liquid in the pan with oil discharged from the outlet of the liquid. The pump works continuously as long as the drive shaft rotates.
Q:What's the difference between a centrifugal pump and a centrifugal pump? What are they used for?
As the name suggests, centrifuges are machines that achieve centrifugal effects by centrifugal action. And you say the centrifugal pump is only specific, and the same as the pump
Q:What are the meanings of the vacuum pump, the front pump and the main pump?
The main pump can be understood as a booster pump, used to improve the vacuum mechanical pump with pumping quantity. As the roots pump, diffusion pumps, molecular pump. These can not use (too much pressure) so the need for mechanical pump drainage, the vacuum chamber is pumped into the rough vacuum, then the main pump starts to work.
Q:What is the Rhodes pump?
The ultimate vacuum of roots pump depends on the pump structure and manufacturing accuracy, and also depends on the limit vacuum of the front pump. In order to increase the limit vacuum of the pump, the roots pump can be used in series. The working principle of roots pump is similar to roots blower. As the rotor continues to rotate, the gas is pumped from the intake air to the space between the rotor and the pump housing V0, and then discharged through the exhaust port. Since the V0 space is fully enclosed after inhalation, the gas in the pump cavity does not compress and expand. But when the top of the rotor turns off the edge of the exhaust and the V0 space communicates with the exhaust side, the gas pressure at the exhaust side is higher, and a part of the gas flows back into the space V0, causing a sudden increase in the gas pressure. As the rotor continues to rotate, the gas is expelled from the pump. Roots pump in the pump cavity, there are two "8" shape of the rotor perpendicular to each other on a pair of parallel axis, by a transmission ratio of 1 of a pair of gear belt movements synchronous reverse movement of each other. In the rotor, the rotor and the pump housing between the wall to maintain a certain gap, you can achieve high speed operation.
Q:What is a solution pump?
Principle and structure features of canned motor pumpThe ordinary centrifugal pump is driven by coupling the pump impeller shaft is connected with the motor shaft, the impeller and the motor rotates while working and shielding pump is a kind of non seal pumps, pump and motor is sealed in a medium filled by pumping the pressure vessel, the pressure vessel only static seal and, by a group of wires to provide a rotating magnetic field and drive the rotor. This structure eliminated the traditional centrifugal pump with a rotary shaft sealing device, it can do no leakage.The pump and motor pump together, motor rotor and pump impeller fixed on the same shaft, use of shielding the rotor and the stator of the motor rotor separated in the medium, its power is transferred to the rotor through the stator magnetic field.
Q:Pump unloading in hydraulic transmission,
Unloading is pumping oil directly back to the tank, the pressure is very low, energy saving
Q:Why can't the centrifugal pump pump the vacuum?
Working principle (taking centrifugal pump as an example):Prerequisites, processes, and requirements for the overall system structure.
Q:Because the water pressure of the booster pump is not enough, it can not work automatically. It can only be operated by hand. It is inconvenient to use.
If the water pressure is not enough, the pump can not start, then it must be wrong. Because if the water pressure is not enough, the pump should be running automatically. It's just because the water pressure is not enough.
