When the pump reaches the normal speed, observe the pressure index of the rotary lobe pump. When the rotary lobe pump installation position has suction requirements, should be in the pump inlet pipe and pump cavity filled with material. When the process requires heating or cooling of the medium, the heating or cooling device should be opened before opening the rotary lobe pump, the heating energy half should be opened 10 minutes in advance, and then the rotary lobe pump.

The rotor pump has a simple structure and can be repaired on-line without dismantling pipes or tools. It can be maintained online by replacing high-strength protective covers and simple mechanical seals. It is mainly reflected in the overall design of the pump cover, the versatility of accessories and simple structural design.

High viscosity rotor pump is a new type of volumetric pump developed according to the needs of petroleum, chemical industry, paint, grease, medicine, dye, food and other industries. Because the product can choose different materials and its structure, it is widely used in the transportation of media with different properties and different viscosity.

Screw pumps are divided into single screw pump, twin screw pump and triple screw pump.The single screw pump is mainly composed of a screw rotor and a rubber stator. The motor drives the rotor to rotate, and the rotor and the stator form a dynamic closed volume cavity. As the helix moves forward, it will achieve the purpose of conveying the medium.

1. The flow rate of single screw pump is proportional to the rotational speed, and the automatic adjustment of flow can be realized by using speed regulation mechanism.2. The compound design of sealing function can realize the transformation and application of many kinds of sealing forms.3. The compound design of flange and bearing can realize the reverse transportation of the product in a short time.

1. Gear pump generally suction 5 meters more than 5 meters need to install bottom valve.2. Check whether the oil inlet is leaking or not, the leakage gear pump has no suction stroke.3. The rotation direction is wrong, it is right to stand on this side of the motor to rotate clockwise.4. If the suction pipe is blocked or the valve is closed, open the valve and check whether the dust cover is open.5. Check whether the rotation is flexible before booting. If there is a dead point, please adjust the concentricity.
