Product Description:

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:Hydraulic pump displacement refers to the pump shaft what?
Displacement of the hydraulic pump refers to the axis of each turn, the volume discharged, called displacement, the unit is ml (ML),
Q:What is the main difference between SK water ring vacuum pump and 2BV water ring vacuum pump?
The 2BV vacuum pump belongs to the machine pump coaxial type direct connection design. It saves space and is easy to install;The use of mechanical seals as standard configuration eliminates leakage and easy maintenance;Smooth running, low noise to 62 decibels;
Q:What is the name of the day pump and ground pump? Specific introduction
Day pumpDay pump is called "day pump", the main reason is that it can deliver concrete to a certain height, make up for other concrete pump transportation shortage. Compared with other concrete pumps, the pump has its own boom, and the concrete can be transported without the use of artificial cloth. It is very convenient for use. At present, China's longest boom pump is 101 meters, which means that 101 meters under the floor can be completed with the help of day pump concrete delivery. In addition, the pump is equipped with a chassis, so compared with the ground pump, it can walk independently, moving very convenient, you can quickly move from one site to another location.
Q:Fire hydrant pump button, under what circumstances do not need to install?
General high voltage system, when normal, use small pump steady pressure.Fire hydrant button lifting pump is one of the multiple pumping methods, and it is an important link of reliable operation of the system.
Q:What are the constant pressure pumps?
Constant pressure pump is also called the booster pump, the name is used for booster pump, its main purpose is water heater booster, with tall low pressure, sauna, bath and other pressure in the apartment, the lack of water pressure, solar automatic pressurization and so on.
Q:Operating procedures for measuring pumps
Pressurization(1) for the discharge pressure below 2.0MPa, then the pump stroke length should gradually increase, each increase of 20%, to maintain 15 minutes.(2) for the discharge pressure greater than 2.0MPa, you need a special pressure, to ensure that the pump discharge pressure gradually increased, each time for the final row pressure of 20%.(3) when the pressure is not increased, the stroke of the pump is gradually increased by 20% strokes per time.Note (1) when pressure is applied, the pressure gauge should be observed at the side of the loading side (slow motion)(2) check ammeter, forbid overload
Q:Fire control center manual start fire pump directly, multi line control
The vertical line NHKVV-7*1.5 is the remote starting line of fire controller to fire pump room.
Q:What is the function of the heating pump system for the water pump design?
As the feed water temperature is higher, before starting, if not enough to warm the pump, the pump body temperature is uneven, there is a hot, cool phenomenon. The upper part is inflated and the lower part is inflated"
Q:What is the difference between centrifugal pump and self suction pump? Which is better?
If the centrifugal pump in full before the start of the shell of the gas, then start after the center of the impeller was thrown in the gas can not be large enough to form the vacuum, so that liquid in the bath can not be sucked, so the centrifugal pump to start before using foreign liquid in the pump housing space filling
Q:What is a gear pump for?
Gear oil pump is through a pair of parameters and the same structure of the involute gear of each other rolling meshing, the tank of low pressure oil to work can do the important parts of high pressure oil. A power unit that converts the mechanical energy of an engine into hydraulic energy. The engine is prone to the following faults during its use.
