One, three screw pump speed selection
The linear relationship between the screw pump's flow rate and rotation speed is related to the low-speed screw pump. Although the high-speed screw pump can increase the flow and lift, the power is obviously increased. The high rotation speed accelerates the abrasion between the rotor and the stator. The screw pump fails prematurely, and the high-speed screw pump's stator length is very short and very simple to wear, thus shortening the life of the screw pump.
Reduce the speed through the reducer or stepless speed adjustment arrangement, make the survey speed adhere to a reasonable range below 300 cents per minute, compared with the high speed operation of the screw pump, the service life can be extended several times.
Second, the quality of the screw pump
Nowadays, there are many kinds of screw pumps on the market. Relatively speaking, the imported screw pump is well-described and the material is exquisite, but the cost is high, some of its effectiveness is not in place, the accessories cost is high, and the ordering cycle is long, which can affect the normal production. operation.
Domestic production usually duplicates imported goods, and the quality of production is generally the same. When selecting products for domestic production, when considering the cost-effectiveness of the products, choose low-speed, long-lead, products with excellent transmission material components and long-life products.
Third, ensure that debris does not enter the pump body
Solid matters mixed in the wet sludge will damage the rubber material stator of the screw pump, so it is very important to ensure that the impurities do not enter the pump cavity. Many sewage plants add a pulverizer before the pump, and some equipment Grid devices or screens, blocking debris into the screw pump, on the grid should be cleared in time to avoid blocking.
Fourth, adhere to stable export pressure
Transmission parts cracked. In order to avoid the damage of the screw pump, an overflow valve is usually bypassed at the outlet of the triple screw pump to stabilize the outlet pressure and maintain the normal operation of the pump.
Fifth, avoid breaking materials
The screw pump must not be allowed to operate under the phenomenon of broken material. Once it occurs, the rubber stator will dry out due to dry friction, and it will burn at high temperatures. Therefore, the grinder is plentiful, and the grill is a necessary condition for the normal operation of the screw pump. In this case, some screw pumps are also equipped with a shut-off stop device on the pump body. When the cut-off occurs, the screw pump will have a self-priming function, vacuum will occur in the cavity, and the vacuum device will cause intermittent operation of the screw pump.
