The second-generation YW(P) series under-liquid sewage pump is a new and patented product latest developed by our company,specially for transporting various sewages under harsh working conditions and made by way of, on the basis of the existing firstgeneration product, absorbing the advanced know-how both at home and abroad and usingWQ series submersible sewage pump's hydraulic model of the most excellent performance at present.
YW series under-liquid sewage pump not only has the all superior performances of theWQ series submersible sewage pump but also greatly opens out the applocable working conditions and fields of use of the latter due to its unique form of installation.

Suitable for steel works, power plant, coal works, mine, hospital,municipal works, chemical industry, medicine, building,hotel, sea-water suction and drainage etc. trades to transport the
industrial sewage with grains and fibres, the city's lovong sewageor rain water and pure water, and also for some flow processesof chemical industry.

The medium temperature not over 50℃ ;
The medium density less than1.2 10 kg/m; need a notice at
order for over than 1.2 10 kg/m ;
The medium's PH valve between 5-11.

Q:The function of centrifugal pump: 4, bearings are set on the pump shaft supporting the pump shaft components, there are two kinds of rolling bearings and sliding bearings. Rolling bearings use butter as a lubricant, refueling should be appropriate, generally 2/3 ~ 3/4 of the volume is too much, will heat, too little, there is noise and fever! The plain bearings are made of transparent oil as a lubricant and fill up to the oil level. Too much oil will leak out along the pump shaft and float *, too little, the bearings will overheat and burn out, causing accidents! In the pump running process, bearing temperature is highest in 85 degrees, generally run at about 60 degrees, if higher, will find the reason (whether there is impurities, whether the oil is black, whether water) and timely processing!

Q:How to adjust the flow of piston pump?: For the swashplate valve controlled by the solenoid valve, the swashplate is in an angle with the cylinder body, so the plunger is reciprocating in the pump cylinder when the cylinder rotates. It goes from 0 degrees to 180 degrees, that is, to the upper plunger position, the plunger cylinder volume gradually increased

Q:Which nuclear submarines use the shaftless pump technology?: Shaftless pumping technology and Simulation of shark skin technology are all the next generation of submarine propulsion technology. At present, there is no submarine in the world.

Q:I want to know the concrete under 60 type pump performance, it is mainly the pump long spiral bored piles, such as the diameter of the pump, transportation distance, pumping height and so on, thank you!: Specification for concrete cylinders:Bore * stroke mm 200 * 1650Hopper capacity L 800Feeding height mm 1400Motor model Y2-280M-4Power kw 90Rated voltage V 380Rated speed r/min 1480Soft starter withoutHydraulic system open-loop

Q:Harm of air pump and pump: Minimum starting current when centrifugal pump of such a small impact on the grid but long closed operation will make the liquid in the pump to the pump overheating temperature is too high will lead to the problem of the seal to a certain temperature will cause deterioration of oil bearing bearing caused by excessive wear and even bite dead

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:You'd better point out the details.... There are 2 best ways of experience and formulaCan you say a simple point, such as multi-stage pump, when the pump is higher than the motor, 30 wire is the next mouth how to do?: Looking forAlignment means the position of the center of rotation of the pump and motor so that they are in the same line.At least three times after the initial installation or after installation:

Q:What is the function of a submersible pump?Do you have any knowledge about submersible pumps?.: The working principle of submersible pumpBefore the pump is opened, the suction pipe and pump must be filled with liquid. Open the pump, the impeller rotating speed, which leaves the liquid together with the rotation under the action of centrifugal force, the left outside impeller injection, injection of the liquid in the pump shell gradually slow the spread of indoor speed, the pressure gradually increased, and then from the pump outlet, the outflow discharge tube. At this time, in the leaves at the center of the vacuum area of low pressure liquid was thrown to the surrounding formation there is no air and no liquid, liquid pool at the surface of the liquid under the action of atmospheric pressure, through the suction pipe into the pump, the liquid is continuously pumped up from the liquid pool is also continuously from the outflow discharge tube.

Q:I live on the 8 floor. Often there is no water. Life is very inconvenient. What kind of pump do I have to install? What should I pay attention to when I buy it? What's the pump for that brand? Should it be installed in that position?: Installation method of hydraulic pump(1) according to the technological requirements and the cavitation conditions of the pump, the installation height check and the civil engineering of the foundation are carried out.(2) prepare a series of flat washers and wedge gaskets of different thickness before installation.(3) according to the characteristics of the pump conveying medium, determine the material of the gasket at the connection and process the gasket.

Q:Rules for operation of centrifugal pumps: Working principle and process flowWorking principle: when the drive motor with high-speed rotating impeller, full of fluid in the pump body under the action of centrifugal force, was thrown from the impeller center to the outer edge of the impeller, in this process, the fluid energy, improve the pressure can, at the same time also increases the energy flow rate increase. The liquid from entering the pump impeller shell, the liquid flow gradually widened, the liquid velocity decreased gradually, which will be part of the kinetic energy into pressure energy, which further improves the static pressure of liquid, and liquid with high pressure in pressure pipeline. When the liquid from the leaves out when the impeller center creates pressure and low pressure than the out plane is big, under pressure drive, liquid is continuously from the center of the impeller suction, with the pressure of continuous discharge.
