Product overview

ZW Ⅱ series self-priming and non-clogged sewage pump is our study of domestic and foreign similar technology is developed on the basis of a new structure of the product. ZW Ⅱ series self-priming without clogging self-priming sewage pump set and blocked sewage into an organic whole, the axial back mixing type, can be like general self-priming centrifugal pump, do not need to install the bottom valve and irrigation water diversion, and inhale row containing large granular solid and liquid long fiber impurities.

Application field

Municipal drainage project, studied the breeding,

Light industry, papermaking, textile, food

Chemical industry, electric power, fiber

Q:Rotary vacuum pump does not meet the requirements of vacuum, what are the reasons?
(1) pump connected outside pipes, containers, pipes, joints and other leakage test instrument, large leakage, rotary gas plug exhaust sound big, and the gas and oil mist discharge, should find leakage cancellation.(2) the assembly of rubber of intake pipe is not proper, damage or aging should be adjusted or replaced.(3) plug hole, the vacuum degree can be decreased, put the oil, remove the tank, loosen the nozzle plate, pull out the oil inlet nozzle, dredge oil hole, try not to use cotton wipe parts.(4) the vacuum system has serious pollution, including containers, pipes and so on. It should be cleaned.(5) the spring of the vane is broken and should be adjusted.
Q:Advantages and disadvantages of canned pumps
Product featuresThe integrated structure of motor and pump adopts static seal, so that the pump is completely free of leakage;Full closed and no leakage structure, can transport toxic and harmful liquid substances;The shielded water-cooled motor and the cooling fan are removed to make the pump operate in a low noise and quiet condition. The utility model is suitable for occasions with high environmental noise requirements;
Q:Household automatic booster pump, how much pressure can you work automatically?
Household automatic booster pump is not started by pressure, it is induced water pump, that is boiled water faucet
Q:How many concrete pump tube diameter
The pump is generally divided into 125 and 150 two, the inner diameter is 125mm and 150mm. And the two kinds of each have high and low pressure points. Low pressure type type 125 pump for the pipeline diameter is phi 133,
Q:Advantages and disadvantages of centrifugal pumps?
Centrifugal pump; advantages and disadvantages:(1) advantages:The structure of the pump is simple and compact, and the centrifugal pump has small area, light weight, little material consumption and high cost for the foundation. Therefore, the cost of manufacturing and installation is less.For high speed operation, the 2 pole or 4 pole motor can be directly connected. The drive structure is simple and easy to install.
Q:Does the reservoir water heater press the booster pump (high marks)?
In addition, the water storage electric water heater has a safety valve is O.7MPa, before buying a booster pump, you can check the water inlet valve spring weakness, see the effect of water, barely even, then use it, do not buy.
Q:What is a feed pump?
Feeding the role of the pump is to make the injection pump inlet pressure, increase the injection pump inlet pipe flow rate, in order to ensure high pressure water injection pump has sufficient supply.
Q:What is the difference between the ground pump and the pump in the commercial concrete?
What you should say here is the concrete pump.Ground pump: the pump will be placed in a position on the site, the pipeline will be sent to the construction of concrete surface,
Q:What are the main performance parameters of hydraulic pumps?
Displacement and flowDisplacement refers to the pump (or motor) every turn a week, by the size of the sealing chamber geometry variable discharge (or enter) the volume of liquid, commonly used unit is ml/r (ml / rev). Displacement can be changed as a variable pump (or variable motor), and the displacement can not be changed into a quantitative pump (or a quantitative motor).Actual flow is the amount of flow at the outlet (or inlet) when the pump (or motor) is operating. As the pump itself leaks, the actual flow is less than the theoretical flow. As the motor itself has an internal leakage, to achieve the specified speed, in order to compensate the leakage, the actual flow of input must be greater than the theoretical flow.
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"
