The transmission mode of slurry pump

• 17  Jul, 2024

The slurry pump needs to be connected to the motor to generate kinetic energy to transport the material out. So what are the connection transmission methods of slurry pump and motor? The following Panshi pump industry introduces the same common transmission methods.

1, DC transmission: the slurry pump and the motor are connected and driven by a coupling, the slurry pump and the motor shaft are on a central shaft, and there are no other transmission links in the middle. DC transmission is reliable and has low failure rate.

2. Belt connection: This transmission means that the motor transmits power to the slurry pump through the belt pulley and 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 pump and the motor are arranged in different directions.

CV transmission: This transmission mode is that the motor is installed above the bearing assembly of the pump, the pump and the motor have no common base, and the motor is installed by bolting a small seat of the motor. This transmission mode is characterized by the pump and motor installation is relatively compact, saving space, suitable for limited site conditions. Because the motor is above, it can also avoid the motor water, causing motor damage. However, if the motor power is relatively large, it is not recommended to use this transmission mode. Because the motor power is large, its weight is relatively heavy, with this installation method may not be very stable, there is a top-heavy situation. Therefore, this transmission mode is generally only recommended for use when small power motors.

3, CRZ and CLZ transmission: This transmission means that the motor is installed on the left or right side of the pump, from the direction of the pump inlet, if the motor is on the left side of the pump, it is CL transmission, if the motor is on the right side of the pump, it is CR transmission, if the pump and the motor are provided with a common base, then the letter "Z" indicates. But for large pumps, because of its own weight and volume is larger, in this case, generally no longer provide a common base. This installation mode, especially because it is installed on the ground, runs relatively smoothly. But it also takes up a lot of space.

4. ZVZ transmission: This transmission mode is the same as CV transmission, which puts the motor at a high level. The difference is that this transmission mode has a common base, the motor is directly behind the pump, and the base of the motor is raised to achieve the purpose of the high motor. Because the orientation of the motor and pump in this transmission mode looks like the capital letter "Z", it is called ZVZ transmission. The characteristics of this transmission mode are similar to CV, because the motor is at a high level, so if there is water leakage on the site, it can prevent the motor from entering the water, so as to protect the motor, there is no limitation on the power size of the motor, regardless of the size of the pump and the motor, you can use this transmission mode.
