In industrial production, it is often used to transport some materials, so the corrosion resistance equipment is widely used. Here are some aspects of the use of acid resistant pump to pay attention to.
The so-called cavitation is the liquid pressure is lower than the liquid temperature of saturated vapor pressure, liquid will evaporate into a bubble, bubble fills the impeller will lead to a decline in the performance of the pump, bubble under high pres
Pump cavitation has external causes, but also through the internal and external factors. The cavitation allowance of the external device, which is provided by the device over energy of vaporization pressure at the inlet of the pump, the internal cause is
Centrifugal pump in addition to a single independent work, but also can be a few pumps in parallel or in series. Parallel operation of the pump, that is, the inlet and outlet of several pumps are respectively connected in the same suction and discharge pi
Operation simple horizontal pump, because the impeller is above the water, before the pump starts, to use a vacuum pump to pump water, because the vertical pump impeller, generally submerged in water, can be directly launched.
1. Check and make sure that the electric water pump rotates in the right direction.

2. After closing, and observe the reading operation noise current meter, to determine whether the normal operation of the electric water pump. If there is abnormal, s
Centrifugal slurry pump is through the work wheel blades rotating centrifugal action make slurry direct access to energy transport equipment, such as Warman pump, two-phase flow pump, centrifugal slurry pump, centrifugal slurry pump, lining plastic pump,
Single-stage centrifugal pump common defects are serious leakage of packing seal, bearing damage, shaft power is too large, the current increase, pump suction is not water, as well as pump vibration, noise and so on.

In recent years, with the development of seabed resources and the development of coal hydraulic transport, the research on the liquid solid two phase flow pump has become active again. In addition, irrigation technology of agriculture in West China is cru
A pump is a machine that pumps the liquid or causes the liquid to be pressurized. It will the prime mover of the mechanical energy or other external energy transmitted to the liquid, so that the liquid energy increases, is mainly used to transport liquid
To ensure to meet the requirements of parts cleaning degree, in the repair, the various parts, the clean of the requirements for the degree is not the same. In the assembly, the cleaning requirements of the complex parts are higher than the non mating par
The sewage pump is a kind of self absorption capacity, so that the pump is in a low level of liquid or water atomizing inhalation chamber, through the impeller speed of the liquid, to achieve the purpose of conveying and promoting the liquid. Sometimes no
1.Fixed connection;
2.Direct connection;
3. Flange type electric motor.
1. Process medium relative density and viscosity index:
Processing method: check the material component to make its viscosity and relative density and design value is in line with the process operator to adjust
As well know QJ deep well pump has lots of advantage. And there are four main advantage:
1. Solve the suction process problem;
2. Solution of pump room;
1. Self priming pump coupling must be strong, and lock nut, beware of loose nut, otherwise easy to cause the impeller to move, causing mechanical failure.
2. In the self sucking pump and motor direct connection drive, should pay attention to the pump s
Vertical multistage centrifugal pump has the advantages of high efficiency, wide range of performance, safe and stable operation, low noise, long service life, convenient installation and maintenance, etc.. Applicable to factories, mines, city, power stat
In practical work, the performance of the pump needs to be adjusted. This is because the water pump in the pump and pipeline under certain conditions only a point, if the pump operating point parameters does not meet the actual needs, can be used to chang
The electric auxiliary feed water pump belongs to the nuclear power station, which is a special safety facility, which is a main pump of the auxiliary feed water system of the steam generator of the million kilowatt class pressurized water reactor nuclear
Centrifugal pump flange connection liquid leakage caused by the following 5 reasons:
1. The working medium in a centrifugal pump temperature change is too large is one of the reasons caused the leakage of flange joints. Because the bolt is not directly
Similar to ordinary pumps, submersible pumps can be used for most occasions, the only condition is the need to have a stable power supply motor. Submersible pump has the following technical characteristics
Pipeline centrifugal pump in use after a long time, it is easy to generate a lot of heat, this time on the need to take the following measures can reduce the temperature below we introduce the four types of Jinan pipeline centrifugal pump cooling
Fire pump is usually in the process of maintenance, fault diagnosis is a key link, one of which is in the process of using the fire pump suction process all of a sudden high failure, we can take the appropriate measures. The following are the common fault
