The structure of the titanium chemical pump parsing

titanium chemical pump before work, water pump body and import pipeline must be stinking liquid medium, prevent cavitation phenomenon occurs, the water in the pump after being thrown, the center of the impeller part form the vacuum area. Side suction liquid unceasingly, and constantly to suction fluid energy, liquid discharge.

1, titanium chemical pump impeller

the impeller is titanium chemical water pump work parts, relying on its high-speed rotating on fluid power and transport the liquid, titanium chemical pump is an important part. According to the structure form, the impeller can be divided into the following three.

( 1) Open impeller blade on both sides with no cover plate, suitable for conveying liquid containing relatively large amounts of suspended solids, low efficiency, the transmission of liquid pressure is not high also.

( 2) Closed impeller impeller are on both sides of the cover plate, the plate with 4 - Six blades, closed impeller efficiency is high, wide application, is suitable for conveying clean fluid containing no solid particles and fibers.

( 3) This half open impeller impeller HouGaiBan only, it is suitable for conveying easy to precipitate or liquid containing suspended solid, its efficiency between open and closed impeller.

2, titanium chemical pump, pump shaft

titanium chemical pump is the main purpose of the pump shaft power, supporting impeller maintain the normal operation in the work place. By its end are connected to the motor shaft coupling, the other end bearing the impeller rotation, mounted on the shaft bearing, axial seal parts, etc.

3, the working process of the titanium chemical pump

( 1) Open pump before, first fill to transport liquid in the pump.

( 2) In the volute pump shell due to the constant expansion of the flow channel, slows down, the liquid can make the most of the kinetic energy into pressure. The last liquid with higher static pressure from discharge into the discharge pipe.

( 3) Fluid after being thrown in the pump, the impeller center formed the vacuum, the liquid level under the action of the pressure and pressure differential pressure in pump, liquid inside the suction pipe into the pump, to fill the position of exclusion liquid.

4, titanium chemical pump seal ring

in order to reduce the leakage and protect the pump shell, with the impeller at the entrance to the corresponding equipped with removable seal ring on the shell. Sealing ring inner hole and cylindrical impeller of the radial clearance is in commonly 0. 1 - 0. Between 2 mm and titanium chemical pump seal ring wear, make radial clearance increases, the amount of drainage pump is reduced, efficiency is reduced, when seal clearance over specified value should be replaced in a timely manner.
