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

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: Is the diaphragm pump and the drain pump one?: First of all, there's something wrong with your concept.Diaphragm pump is in accordance with the way the pump classification, drain pump is in accordance with the use of pumps classification.

Q: Is the vacuum pump air compressor?: A vacuum pump is a device or device that uses a mechanical, physical, chemical, or physical chemical method to pump a vacuum from a container to be evacuated. Generally speaking, a vacuum pump is a device that uses various methods to improve, produce, and maintain a vacuum in a confined space.

Q: Why can the centrifugal pump hold down the pressure?: The centrifugal pump can hold pressure because of the suction pipe in the pump at the entrance of a non-return valve (valve).

Q: What's the meaning of the pump head in the water pump, please advise, thank you: The pump head of the centrifugal pump refers to the shell that contains the impeller and impeller, and also includes the shaft part that drives the impeller. It can be used as the part of the motor and shaft coupling and the base.

Q: What is the function of the heating pump system for the water pump design?: Will cause some of the internal friction gap disappeared, the coupling center damage. In this case, starting the pump inevitably results in vibration, friction, etc.

Q: Is the centrifugal pump large or small?: NPSH is also called cavitation, cavitation is too big to be.3, pump the liquid when working in the impeller inlet will produce vapor due to a certain vacuum pressure, vaporization of the air bubbles in the liquid particle movement under the impact of erosion on the impeller, the metal surface, thus undermining the impeller and other metal, then vacuum pressure is called vaporization pressure, NPSH is excess vaporization pressure of surplus the energy position of the unit weight of the liquid in the pump suction port of. The unit with annotation, (NPSH) r with. The absorption process is necessary NPSH H: pump suction fluid allows the vacuum pump installation height is allowed, in meters.

Q: What are the main performance parameters of hydraulic pumps?: speedOperating speed is the actual rotation speed of a pump (or motor) at work.Rated speed is the maximum speed that can operate normally for a long time under rated pressure. If the pump exceeds the rated speed, the work will cause insufficient oil absorption, vibration and noise, the parts will suffer cavitation damage, life expectancy.Minimum steady speed is the minimum speed allowed for normal motor operation. At this speed, the motor does not appear crawling phenomenon.

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's the submersible pump?What is a submersible pump, and what about it?: Submersible pump is a pump directly on the water inside the pump, eliminating the water inlet pipe, eliminating the trouble of ordinary water, is very convenient, just a pool, pool, bucket, water tank water level is shallow to be able to work, meet your requirements of pumping drainage
