Vertical Multistage Pump

 

1.Introduction:

CDL/CDLF high pressure water pump is special in high pressure, made of stainless steel 304 or 316, all parts touch with liquid are of stainless steel. The pump is vertical non-self priming multistage centrifugal pump, which drived by a standard electric motor.The motor output shaft directly connects with the pump shaft through a coupling. The pressure resistant cylingder and flow passagecomponets are fixed between pump head and inlet and outlet section with tie-bar bolts. The inlet and outlet are located at the pump bottom at the same plane. This kind of pump can be equipped with an intelligent protector to effectively prevent it from dry-running, out-of-phase and overload.

Q:What does the pump mortar do?
In order to effectively reduce the flow resistance of concrete and pipe, to avoid obstruction caused by pipe sticking and to achieve normal pumping, and its role is generally only pumps.
Q:What are the reasons for sealing damage of centrifugal pumps?
The reasons for sealing damage of centrifugal pumps are as follows: six, the specific contents and handling methods are as follows:First, the centrifugal pump water quality is poor, containing particles.As a result of poor water quality, containing small particles and medium hydrochloride content is high, forming abrasive wear, centrifugal pump seal plane or pull the surface, resulting in groove, ring groove and so on.Treatment method: improve water pressure or medium, replace machine seal.
Q:Why should the pump be closed when the centrifugal pump is started?
On the other hand, the water on the pipe of the inlet pipe of the pump is stationary before the pump is opened, such as the sudden acceleration, and the water behind it can not keep up, which will cause the pressure of the inlet to drop suddenly and vaporize the water, and the centrifugal pump will be evacuated. (because of the centrifugal pump is rotating centrifugal force generated by the pump, leaf water and steam driven (gas) quality is very light, according to F= Ma, the centrifugal force is small, the pump can not be water sent).
Q:Brief description of centrifugal pump on / off operation
(3) check whether the turning rotor is easy and flexible, check the pump body is clang or friction sound.(4) the protective cover is installed, and the shield contact.(5) clean the pump frame and do a good job of sanitation.(6) open the inlet valve, make the liquid full of pump body, open the vent valve, clean the air and close it. If the hot oil pump, it is not allowed to open the air valve exhaust, to prevent hot oil channeling spontaneous combustion, if there is a dedicated vent pipes and tanks, you can vent the pipe line air and cold oil.(7) the hot oil pump should be preheated slowly before starting. Especially in winter, the pump body and the pipe should be preheated at the same time, so that the temperature difference between the pump body and the conveying medium is below 50 centigrade.(8) the oil must be sufficiently dehydrated before being introduced into the oil pump.
Q:Water pump spoon pipe for power plantWhich hero can tell me what is the water pump spoon tube ah? And its role
By adjusting the amount of oil entering into the hydraulic coupler, the torque of the hydraulic coupler can be controlled
Q:Household automatic booster pump, how much pressure to work automatically, the water pressure and how many kilograms?
Household automatic booster pump is not started by pressure, it is induced water pump, that is boiled water faucet
Q:What are the parts of a pump? How do you classify it?I just want to know
According to the working principle can be divided into: centrifugal type and volume type centrifugal pump. By the centrifugal force of the impeller will accelerate the refrigerant, through to stay, so as to achieve the purpose of boosting; volume by changing the refrigerant in the flow volume to boost purpose.According to the media and installation conditions, water pump: centrifugal pump used: the impeller pump shaft, a curved blade on the impeller impeller outlet. The central entrance water vertically along the tangential direction of axial flow pump: high speed, large flow, low lift, mixed flow pump and centrifugal pump structure similar to that of the blade outlet angle is different, wide flow channel, close to the performance of axial flow pump displacement pump: safety valve must be opened before the start (metering pump, screw pump)
Q:Pneumatic diaphragm pump compressed air pressure is 4 kg, the discharge pressure is how big?
Pigment pressure is less than 0.4mpa,About 0.3. Go up.As the pump diaphragm is in the middle of a connecting rod, equivalent to the cylinder cavity, the pressure will be reduced; and because of the loss of pigment tube pressure will be reduced.
Q:What is the distance between the pump and the wall?
What do you mean by that? If your pump is parallel to the wall! Then, the wall of the pump near the wall is usually 500mm. This is an empirical data, considering the import pipe length, pump maintenance and motor heat dissipation and other aspects of the situation to determine. Dozens of pumps installed in our company are placed in this size! Hope to be of help to you.
Q:How accurate is the metering pump?
Three automatic compensation valve device widely used in diaphragm metering pump, especially with suction height requirements, can only be used by three separate Fujian (safety valve, discharge valve and oil supply valve) compensation device.
