Mechanical sealant failure reasons: rubber parts aging, deformation, mainly in the hot water pump aging, deformation. Mechanical seal failure performance of the phenomenon for the water temperature is too high, the media dissolved rubber. Loss of flexibil

Leakage of the mechanical seal is the dynamic and static ring plane wear.There are six aspects of the dynamic and static ring plane wear: A tight installation,Install too loose,The water quality is poor, Dry operation caused by dry grinding damage, Cavit

Multistage pipeline centrifugal pump pump shaft power is generally used to test the steel string torque meter. The torque, speed and power can be measured by measuring the torque, speed and torque on the shaft.
Two steel string sensors are respectively a

Generally each pump to install a valve, bottom valve is usually installed in the water below, at the beginning of the performance was acceptable, with a long time, due to the accumulation of silt and other debris blocked, can easily lead to valve jam, eve

Centrifugal pump should be in accordance with the recommended liquid stop selection, and check the demand function, analysis of suction, crowding out the premise is intermittent operation are still in a row operation. Centrifugal pump should be in or near

Various types of submersible sewage pump and submersible pump wells with different cooling methods can be divided into four basic types. Well submersible sewage pumps and wells with submersible pump according to its internal structure divided into filling

Chemical pump in the use of the process, usually by supporting the motor to bring power, the correct selection of supporting the motor is very importan

In the design of centrifugal pump, generally need to be given the design parameters of this: flow Q, head H, speed N, cavitation margin NPSHr and efficiency, etc.. According to the above parameters can be determined preliminarily centrifugal tip structure

Model conversion method. The method is simple and reliable. The specific method is to first and the design of a centrifugal pump similar to the centrifugal pump, the flow of all parts of the geometry of the size of all enlarged or reduced.

Centrifugal pump is the use of impeller rotation and the centrifugal force generated by the water to work. Pump before the start, we must make the shell and the water pump pipe filled with water, and then start the motor, the pump shaft to drive the impel

Water suction pipe.
When the diameter is less than 0~1., it is 1 2m/s 250mm;
Diameter at 250~1000mm, for 6m/s- 1.2~1.

The liquid corrosion centrifugal pump is suitable for transporting corrosive medium, so it is widely used in the chemical industry. We in the use of found the FY type liquid pump of the graphite Teflon bearing is easy to wear, sometimes even connecting pu

Stainless steel self priming pump to make our use of a very wide range of pump products, and as a kind of pump can be imagined as a kind of water pump. As an electrical device, operation in the case of a liquid is extremely dangerous. So how do we get rid

Pumps are of great use in people's lives, but on different types of. Things you need to pay attention to when you use are different, because of their different functions, the use of the different aspects of the. So you can pay attention to the use of the

Globe valve leakage in terms of words, the valve is different, the leakage position is different. Of packing leakage, matter packing gland, if the packing too loose, it is necessary to add filler, if directly is body leakage, low pressure can be welded up

Axial flow pump is a kind of water pump with high flow and low head which is used to produce thrust force (Sheng Li) in the water body, which is vertical, horizontal, oblique and cross flow type.

Pipeline centrifugal pump is the transport of water and physical and chemical properties similar to water and other liquids or booster, suitable for in industrial and urban drainage, increased construction booster pump water supply, garden sprinkler, fire

Pipeline pump is single suction a single-stage centrifugal pump, which belongs to the vertical structure, because its import and export in the same line, and the import and export of the same caliber, imitates a section of pipe, installed in any position

Submersible electric pump is a kind of medium pressure mechanical oil production equipment used in oil field. With the improvement of the degree of automation of oil field development, original submersible electric pump fixed frequency control cabinet sto

Fluid engineering equipment, such as tanks, filters, compressors, pumps have to install a variety of valves, so that the normal use of the system and the maintenance of these devices, replacement. Such as electric ball valve, electric gate valve, electric

Generally use external erosion method. Some easy to precipitate, containing solid particles of the medium with ordinary valve adjustment, often in the throttle, the guide is blocked. Can take the erosion of gas on the lower valve cover Cypriot department

Generally use external erosion method. Some easy to precipitate, containing solid particles of the medium with ordinary valve adjustment, often in the throttle, the guide is blocked. Can take the erosion of gas on the lower valve cover Cypriot department

In the production process, in order to make the medium pressure, flow and other parameters in line with the requirements of the process flow, need to install the regulator to adjust the above parameters. The main working principle of the regulating mechan

Gate valve is used as a cut-off medium, the entire flow through the full open, the pressure loss of the media at this time is the smallest. Gate valves are generally applicable to the condition that does not require frequent opening and closing, and to ke

Regulating valve in the process of operation, there are often card blocking and other failures.
