Selection of the speed of screw pump

Screw pump flow and speed into a linear relationship, compared to the low speed of the screw pump and the high speed of the screw pump although can increase the flow and head, but the power was increased, the high speed accelerated the wear between the rotor and the stator, will enable screw premature failure, and high speed screw pump fixed rotor length is very short, easy to wear, so as to shorten the service life of the screw pump.北京第二機床廠LB-1.6/25外圓磨用冷卻螺桿泵

Through the decelerating mechanism or stepless speed regulating mechanism to reduce speed to speed to keep at 300 per turn following a more reasonable range, compared with the high speed of the screw pump, life can be extended several times.

Two, the quality of screw pump

The type of screw pump more, relatively speaking, the import of the screw pump design is reasonable, sophisticated materials, but higher prices, services, and some are not in place, accessories high price, order cycle length may influence the production of normal operation.

Most of the domestic production of generic imported products, product quality varies greatly, in the selection of the domestic production of products, in considering the price, choose low speed, long course, high transmission capacity component material, rated long life products.

Three, to ensure that the debris does not enter the pump body

Wet sludge mixed with the solid debris will of screw pump, the rubber material damage to the stator, so to ensure that debris does not enter the pump cavity is very important, many wastewater treatment plant in the pump before the installation of a grinder, there are installed grid device or filter, blocking debris into the pump, the grid should be cleared in time to avoid clogging fishing.

Four, avoid breaking

Screw pump must not be allowed to feed off the operation, the occurrence, rubber stator due to dry friction, and instantly generate high temperature and burn out, so, grinder intact, grille flow is one of the necessary conditions for the normal operation of the screw pump. Therefore, some screw pump pumps, is an installed end feeding stop device, when cutting, because the screw pump has the characteristics of self suction function, the cavity will produce vacuum, vacuum device will make screw pump to stop running.

Five, maintain a constant outlet pressure

Screw pump is a kind of rotary pump, when the outlet end is blocked, the pressure will gradually increase, so that more than a predetermined pressure value. At this time, the motor load increased dramatically. Transmission machinery related parts of the load will exceed the design value, serious will occur when the motor burned, transmission parts broken. In order to avoid damage to the screw pump, the general will be in the screw pump outlet will be installed back to the oil valve, with a stable outlet pressure, to maintain the normal operation of the pump.

Common problems

1 severe vibration or noise of the pump body:

Cause: pump installation is not strong or the installation of pump is too high; motor ball bearing damage; water pump shaft bending or with the motor spindle is not concentric, not parallel, etc..

Treatment method: the installation height of the pump or the lower water pump, the replacement of the motor ball bearing; the correct bending of the pump shaft or the relative position of the pump and the motor.

2 drive shaft or motor bearings overheating:

Cause: lack of lubricating oil or bearing rupture, etc..

Handling method: filling the lubricating oil or replacing the bearing.

3 no water pump:

Cause: pump body and suction pipe is not filled with water; the dynamic water level is lower than the water pump, water pipe rupture, etc..

The sealing surface between the screw and the shell is a space surface. There are non sealing areas such as AB or de on this surface, and a plurality of triangular gap ABC and def are formed in the groove of the screw. The gap of these triangles constitutes a liquid channel, which makes the active screw groove B is connected with the groove A and C on the driven screw. The groove B, C and along the spiral wound to his back, and D, respectively and the groove on the back of the E connected. Because in the slot D, e and slot f (it belongs to the other end of the spiral) convergence of the sealing surface, there are also similar to the front of the angle shaped notch a 'B' C ', so D, F, e will be connected. In this way, groove ABCDEA also constituted a "robust" shaped seal space (such as the use of single thread, the groove will be along the axial direction disc Rao screw, the suction outlet through, unable to form a tight seal. Is not difficult to imagine,北京第二機LB-1.6/25外圓磨用冷卻螺桿泵 in such a screw, will form many independent "infinity" shaped sealed space, each a sealed space occupied by the axial length of is exactly equal to the tired rod guide t. Therefore, in order to make the screw energy
