Overview

The corrosion-resistant and wear-resistant slurry pump has an infinite number of blades in the impeller, and the distance between the blades is extremely small. The liquid is constrained by the blades and has no room for free movement. It can only flow out from the impeller of the cyclone through the blade gap, with the relative streamline of the liquid and the shape of the blades.

Product Details

The flow components of GMZ50-15-15 corrosion-resistant and wear-resistant slurry pump are made of high-strength and wear-resistant materials, suitable for conveying slurry with strong abrasion, high concentration, and large particles. Within the maximum working pressure range of the pump, it can be used in series in multiple stages. GMZ wear-resistant slurry pump has interchangeable overcurrent components made of various materials according to the different suction media, suitable for conveying abrasive or corrosive, large or fine particle slurry. GMZ pump can be widely used in metallurgy, mining, power, coal mining, water conservancy, chemical industry, light industry, petroleum and other sectors, and is an ideal equipment for civilized factories.

2、 Structural characteristics

1. By adopting a special single blade or double blade impeller structure, the sewage passage capacity is greatly improved, which can effectively pass through 5 times the fiber material of the pump diameter and solid particles with a diameter of about 50% of the pump diameter.

2. The overcurrent components of the GMZ slurry pump are made of high-strength wear-resistant materials, suitable for conveying slurry with strong abrasion, high concentration, and large particles. Within the maximum working pressure range of the pump, it can be used in series in multiple stages.

3. The GMZ type pump has interchangeable flow components made of various materials according to the different suction media, suitable for conveying abrasive or corrosive, large or fine particle slurries.
4Shaft seal part: There are three forms of shaft seals: secondary impeller shaft seal and packing shaft seal, and mechanical seal.

(1) Auxiliary impeller shaft seal: When the positive pressure value at the pump inlet is not greater than 10% of the pump outlet pressure value, a single-stage pump or a multi-stage series third stage pump can use an auxiliary impeller shaft seal. The auxiliary impeller shaft seal has the advantages of not diluting the slurry and good sealing effect.

(2) Packing shaft seal: The packing shaft seal has a simple structure and is easy to maintain. It requires the use of shaft seal water. For working conditions that are not suitable for using a secondary impeller shaft seal and pump suction working conditions, packing shaft seals can be used.

(3) Mechanical seal: For working conditions that are not suitable for the above two types of shaft seals, mechanical seals are used to reduce the maintenance frequency of the shaft seal part.
4. Transmission part: This series of pumps adopts the same series of transmission, including bracket and bearing components. The pump shaft diameter is large, the rigidity is good, the cantilever is short, and it will not bend or vibrate under harsh working conditions. The bearings are single row tapered roller bearings and deep groove ball bearings, which can withstand the maximum axial and radial loads of the pump when used in combination. The bearings are lubricated with thin oil, and there are sealed end caps at both ends of the bearing body, which can effectively prevent slurry and other pollutants from entering the bearings. The pump is equipped with two rubber hose joints in the bearing body, which can be connected to the water source to cool the bearing chamber. Therefore, it can work at high ambient temperatures, ensure the safe operation of the bearings, and have a high service life.

The basic equation is derived based on the assumption of an infinite number of blades. Due to the large number of blades and long flow channels in the corrosion-resistant and wear-resistant slurry pump impeller, the trajectory of liquid movement in the flow channel can be well defined. Therefore, it is assumed to be closer to the actual situation. But as the pump speed increases, the impeller shrinks, the number of blades decreases, and the flow passage becomes wider, resulting in a significant difference between the assumed flow and the actual liquid flow situation.

In an infinite number of blade impellers, the distance between the blades is extremely small, and the liquid is constrained by the blades, leaving no room for free movement. It can only flow out of the impeller along the blade gap, with the relative streamline of the liquid and the shape of the blades; In impellers with a limited number of blades, the degree of liquid being held by the blades is greatly reduced, allowing the inertia of the liquid to be manifested. The actual flow in the impeller can be approximated as the superposition of axial vortex flow and uniform flow (cross flow) passing through the stationary ten wheels. The superposition of two flows causes relative velocity slip at the impeller mouth.

2、 If there is a malfunction in the wear-resistant slurry pump during operation, it is necessary to first identify where the problem lies and take appropriate measures. Generally, the following methods can be used for reference:

1. The solid sediment inside the vortex shell is blocked, and measures can be taken to remove the blockage.

2. If the impeller or inlet and outlet pipelines are blocked, cleaning the impeller or pipeline can be taken. If the impeller is severely worn, replacement should be taken. If there is air leakage at the packing port, the packing should be tightly compressed. The conveying height is too high, resulting in excessive resistance within the pipe. To address these issues, reduce the conveying height or resistance.

3. If the axis is different from that of the feeding box, the main reasons are large machining errors and incorrect installation. Attention should be paid to checking whether the installation is correct after installation. If the sealing water ring is severely worn, a new water ring needs to be replaced. If the sealed water pipe is blocked, the sealing water cannot enter the middle of the packing, causing rapid wear of the packing and resulting in material leakage. Clear the blocked water pipes and keep the sealing water clean.

The application of slurry pumps in various fields can lead to more or less problems. To identify the problem and solve it, it is also necessary to perform certain maintenance and upkeep on corrosion-resistant and wear-resistant slurry pumps!
