Screw pump can be divided into single screw pump and twin screw pump We usually use the screw pump must pay attention to the maintenance of the screw pump, screw pump maintenance in fact, and other machines as long as you pay attention to his features and features will be able to Well maintained. First of all, to ensure that other debris does not enter the pump body If there is solid debris into the pump will screw the rubber material stator damage, it is important to ensure that debris does not enter the cavity of the pump, and some before the pump plus Installed a grinder, and some grille installation or filter, block debris into the screw pump, grill should be promptly cleared to avoid clogging. The second to avoid the screw pump in the case of broken use. Screw pump is never allowed to run in the case of broken material, once occurred, the rubber stator due to dry friction, instantaneous heat generated and burned, so the grinder intact grille smooth is one of the necessary conditions for the normal operation of the screw pump is In this case, some screw pumps are still installed in the pump body off material shutdown device, when there is a broken material, due to its self-priming screw pump features, the cavity will have a vacuum, the vacuum device will stop the screw pump operation. Third constant outlet pressure Screw pump is a positive displacement rotary pump, when the outlet is blocked, the pressure will gradually increase, so that the pressure exceeds the predetermined value. At this time the motor load increased dramatically. Transmission machinery related parts load will exceed the design value, severe motor burn occurs, the transmission parts broken. In order to avoid damage to the screw pump, generally installed at the outlet of the screw pump bypass relief valve to stabilize the outlet pressure to maintain the normal operation of the pump. Reasonable selection of the fourth screw pump speed Screw pump flow and speed into a linear relationship, relative to the low-speed screw pump, screw pump with high speed although it can increase the flow and lift, but the power was significantly increased, high speed accelerated the rotor And the stator wear, the screw will inevitably lead to failure, and high-speed screw rotor stator length is very short, easy to wear, thus shortening the life of the screw pump. Through reducer or stepless speed regulation mechanism to reduce the speed, the exploration speed maintained at a reasonable range of three hundred revolutions per minute, and high-speed operation of the screw pump, the service life can be extended several times. Of course, there are many ways to maintain the screw pump which requires us to pay more attention when it is used. As long as careful observation will have a good maintenance of the screw pump.
