Screw pump is measured changeably because of its carry, attract faculty oneself strong, reversible turn, can carry the characteristic such as the liquid that contains solid grain, in sewage treatment plant, be used to be in widely carry water, wet mud and garrulous to coagulate respect of agent medicine fluid. Screw pump is chosen should follow economy, reasonable, reliable principle. If designing type selecting respect to consider not, after can giving use, management, maintenance brings a trouble, one when choose so needs actually by production, reasonable and reliable screw pump can assure to produce success already, can reduce again repair cost. A few experience introductions that using us screw pump now are as follows:

One, the rotate speed of screw pump is chosen

The discharge of screw pump and rotate speed concern into linear, relative to the screw pump at low rotate speed, although the screw pump of high rotate speed can add discharge and lift, but power increases apparently, high rotate speed quickened the wear and tear between rotor and stator, sure make screw pump premature invalidation, and the calm rotor length of pump of screw of high rotate speed is very short, wear away extremely easily, shortened consequently the service life of screw pump passes decelerate opportunity or orgnaization of stepless speed regulation reduces rotate speed, make collate rotate speed maintains turn in every minutes the following inside relatively reasonable range, the screw pump photograph that runs with high speed is compared, service life can be lengthened severalfold.

2, the character of screw pump

The sort of the screw pump on the market is more now, relative to character, the screw pump design of the entrance is reasonable, material is qualitative excellent, but the price is higher, service respect some does not reach the designated position, fittings price is high, order goods cycle grows, what affect production possibly is normal move.
Home produces be modelled on mostly entrance product, produce character to measure the good and bad are intermingled, when the product that chooses domestic production, when considering its sex price to compare, choose low rotate speed, grow lead, material of transmission capacity component is qualitative admirable, the product with rated long life.

3, ensure sundry do not enter pump housing

The solid of the interfuse in wet mud is sundry can qualitative to the balata material of screw pump stator causes damage, ensure so sundry the housing that does not enter pump is very important, plant of a lot of sewage is added before pump installed disintegrator, also some installation grille device or mesh, hold back sundry enter screw pump, answer to grille lest cause,seasonable Qing Dynasty is scooped up jam.
