The slurry pump needs to be connected to the motor to generate kinetic energy to transport the material out.
- Coupling direct connection: This transmission method is generally represented by the letter DC. This transmission method means that the motor and the slurry pump are directly connected by a coupling. Common couplings include claw couplings, pin couplings, and diaphragm couplings. The pump factory will select the appropriate coupling according to the matching motor power.
2. Belt connection: This transmission method means that the motor transmits the power to the slurry pump through the pulley and the belt. Belt connection is divided into CV transmission, CRZ transmission, CLZ transmission, ZVZ transmission, four transmission modes. The difference between these four transmission modes is that the arrangement of the pump and the motor is different.
1）CV transmission: In this transmission mode, the motor is installed above the bearing assembly of the pump. The pump and the motor do not have a common base, and the motor is installed by bolting a small seat of the motor. The characteristic of this transmission mode is that the installation of the pump and motor is relatively compact, which saves space and is suitable for use in limited working conditions. Since the motor is above, it can also avoid water entering the motor and causing damage to the motor. However, if the motor power is relatively large, this transmission method is not recommended. Because the power of the motor is large, its weight is relatively heavy. If this installation method is used, it may not be very stable, and it will appear top-heavy. Therefore, this transmission method is generally only recommended for use with low-power motors.
2）CRZ and CLZ transmission: This type of transmission means that the motor is installed on the left or right side of the pump. Viewed from the inlet direction of the pump, if the motor is on the left side of the pump, it is CL transmission, and if the motor is on the right side of the pump, then It is a CR drive. If the pump and motor have a common base, the letter “Z” means. But for a large pump, because of its own weight and volume, in this case, a common base is generally no longer provided. The feature of this installation method is that it runs relatively smoothly because it is installed on the ground. But it will take up a lot of space.
3）ZVZ transmission: This transmission method is the same as the CV transmission, in which the motor is placed at a high position. The difference is that this transmission method has a common base, the motor is directly behind the pump, and the purpose of the motor is achieved by raising the base of the motor. Because the orientation of the motor and pump in this transmission method looks like a capital letter “Z”, it is called ZVZ transmission. Since the motor is in a high position, if there is water leakage on site, the motor can be prevented from entering water, thereby protecting the motor. There is no limit to the size of the motor power, regardless of the size of the pump and motor, this transmission method can be used.
