转子泵选型中转子材质的选择

Selection of Rotor Material in Rotor Pump Selection

At present, there are many types of cam rotor pumps. The choice of rotor material needs to be selected according to the specific operating conditions. According to the rotor material classification, cam rotor pumps can be divided into two categories: metal rotor pumps and rubber rotor pumps: First of all, the metal rotor pump is relatively low in terms of production cost, but for some special media materials, it is not suitable for the oil field or the printing and dyeing industry. This kind of harsh working conditions, the metal rotor and pump are There is zero contact between them, so the self-priming capacity of the rotor pump is very poor, so the volumetric efficiency is relatively low, and it also limits the pump outlet pressure. The rubber rotor pump can make full use of the high elastic energy of rubber, so it can achieve a better fit. In this way, the self-priming capacity and volume efficiency of the pump can be greatly improved.

Precautions in the rubber rotor injection process

The rubber rotor injection process mainly involves the treatment of the metal skeleton and the injection mold. During the operation, pay attention to the following points: 1. In the metal skeleton treatment step, the high-temperature degreasing is heated in the form of an oven, and the temperature is set to 200 °. C-250 ° C; 2. After sandblasting operation, the volatile solvent is one of benzophenone and xylene; 3. In the coating operation, the drying method can be dried or air-dried, and the drying temperature is set to 120 The temperature is about 10 ° C, the time is about 10 minutes, and the air-drying time is longer; 4. Two layers of glue are selected;

What operations need to be performed on the metal skeleton of the rubber rotor pump rotor injection?

In the rubber rotor pump injection process, the treatment of the rotor metal skeleton is particularly important, which determines the stability of the rotor in the later use and the self-priming pressure that can be achieved. The main purpose of processing the metal skeleton in the injection molding process is to increase its adhesion. The main steps are as follows: 1. Degreasing the processed metal skeleton at high temperature; 2. Sandblasting the surface that is in contact with the rotor; 3. Use The volatile solvent cleans the surface of the metal skeleton; 4. After the metal skeleton is cooled, the glue is applied, and after cooling, the next step is performed. In the overall processing of the metal skeleton, more details are required, and reasonable time control is especially important.

Application of cam pump in biogas project

Rohde cam pumps are a highlight in biogas systems. Compared with the traditional single screw conveying biological raw materials, the characteristics and advantages of the cam pump are quite obvious. First of all, when the cam pump conveys the medium, the medium fills the closed cavity formed by the rotor and the pump casing, and is discharged with the movement of the cavity. Therefore, the cam pump is most suitable for conveying high particulate matter such as biogas raw materials and particle diameter Large medium; Second, the cam pump's conveying parts are two elastic contact cam rotors, and the rotor has a variety of wear-resistant and adaptable materials and structures to choose from; Third, the cam pump also has online Maintenance, compact structure, small footprint, few wearing parts (only one pair of rotor and mechanical seal), long wearing parts, etc. Fourth, cam pump is an efficient positive displacement pump, under the same working conditions , Its starting torque and running torque

Advantages of rotor pumps in sweeping and sweeping operations

The unloading operation of oil tankers is generally completed by the crane pipe system of the oil terminal. When the oil tanker docks, many crane pipes will connect the tanker and the oil pipeline. The function of the line sweep pump is to evacuate the liquid remaining in the pipe after the crane pipe is loaded and unloaded. The line sweeping operation generally takes less than 15 minutes. If the line sweeping pump cannot be completed or takes a long time to complete, it will attract complaints and even claims from the tanker owner. Before the crane tube and the tanker are separated, the liquid in the crane tube must be drained. Otherwise, the crane tube may be crushed. In the past, vacuum pumps and centrifugal pumps were commonly used to achieve the desired results by using the siphon effect. Now, using the strong self-priming and idling characteristics of the rotor pump, the expected oiling effect can be directly achieved without the need for a filling pump operation, which can greatly save time loss on the pipeline. Pump selection depends on the medium. Usually, a pump can only be used for

粪便污水输送泵(高含沙量污水的输送解决方案,替换螺杆泵)

Manure sewage transfer pump (high sand content sewage transfer solution, replace screw pump)

Fecal sewage is a kind of sewage with a lot of fibers and debris. In the transportation of fecal sewage, the entanglement of fibers and hair has always been the biggest problem that plagues users. Many users have used screws at the station for raw water transportation In pump experience, screw pumps use the rotation of the screw to suck and discharge liquid: the rotor and the stator are closely fitted and engaged with each other; between the suction and discharge ports of the pump, it is divided into one or more sealed spaces. The liquid in the suction chamber is enclosed therein, and continuously moves from the suction chamber to the discharge end in the axial direction of the screw. Use experience shows that before the material enters the cavity formed by the rotor and the stator, it is very easy to be entangled in the position of the rotating shaft, and it may even cause blockage at the entrance of the stator and rotor cavity. When the pump body is blocked, in view of the complicated structure of the screw pump, the complicated and time-consuming maintenance work is a headache.

凸轮转子泵转子与泵壳间隙对性能的影响

Effect of clearance between cam rotor pump rotor and pump casing on performance

The cam rotor pump forms a nearly sealed space between the rotor and the pump casing to achieve the effect of conveying the medium. Therefore, its performance parameters and reliability are closely related to the size of the pump gap, which is determined by the structure, shaft, and rotor of the pump. Factors such as the force and deflection of the part. Among them, the deflection of the shaft has a great impact on the normal operation and life of the rotor, mechanical seals and bearings. The main reasons are as follows: 1. The rotor is the main overcurrent component of the medium conveyed by the cam rotor pump. In the process, the medium is transported from the pump inlet to the outlet. If the rotor is deformed too much in the process, once the gap is exceeded, it will cause the rotor to directly contact the fixed parts (such as the pump body or wear-resistant lining) to cause friction, affecting The normal operation of the cam rotor pump shortens its working life. Here the deformation of the rotor includes the

污泥进料转子泵应用介绍

Application of Sludge Feed Rotor Pump

The sludge from the sewage treatment plant after sedimentation and concentration needs to be transported to a dewatering machine (centrifugal dewatering, belt dewatering machine, or plate and frame filter press) by a sludge pump (Rod cam rotor pump). The solid content is about 3-4%, and the sludge contains solids, fibers, and sand. Generally, a cutting machine (or a sludge crusher) needs to be installed in front of the sludge pump (Rodder cam rotor pump). At this station Traditionally, single screw pumps have been used in traditional processes, but they are gradually replaced by cam pumps due to factors such as short wear life, high parts costs, and complex maintenance. Rohde cam rotor pumps have on-line maintenance design, wear resistance, cheap accessories, anti-winding, and low product cycle. They are favored by customers. The sludge pump is equipped with a frequency converter. The flow and pressure of the pump are controlled by the frequency converter. Rohde cam rotor pumps are very good at this.
