GN is a major centrifuge manufacturer with state-of-the-art manufacturing processes and advanced domestic and international processing technologies. The manufacturing precision of advanced imported processing equipment guarantee equipment in Taiwan, Germany and Italy has reached international standards. Mainly involved in the industry: drilling fluid solid control treatment, industrial wastewater treatment, waste mud treatment, oil residue separation, municipal sewage purification engineering, mining wastewater treatment, river dredging and so on. It is especially suitable for the solid solution with small particle size, small solid-liquid two-phase density difference (solid-liquid phase specific gravity difference >0.05), and the integration scheme of liquid-solid separation occasions where separation is difficult. It can also be used for separation between liquids or between liquid and solid. It has been widely used in modern industrial processes, and is widely used in chemical, food, light industry, paper, mining and other industrial fields.

 

Some parts are characterized by:

 

1, auger

 

The screw ejector is the core component of the centrifuge. Its main function is to transport sediment and provide drainage channels. Its structure, materials and parameters are not only related to the production capacity and service life of the centrifuge, but also directly affect the efficiency and separation of slagging. effect. The machine adopts a column/conical spiral, which consists of a spiral blade, a mandrel, a spiral-shaped end shaft, etc., and is supported on the drum-sized end cap by bearings on both ends of the journal, and the bearing is lubricated with grease.

 

All important parts of the GN solid control centrifuge are made of 2304 duplex or 304/316 stainless steel.

 

The spiral blade is inlaid into a replaceable wear-resistant alloy piece, which can extend the service life of the pusher. The acceleration cone output port of the mandrel is equipped with a replaceable alloy grinding port wear-resistant sleeve, and the acceleration shaft of the mandrel is equipped with an acceleration. Strip design can improve the processing effect. The use of open-cell spiral blades improves the clarification effect.

 

2, the host base

 

It mainly plays the role of supporting and installing the whole rotary system. It also plays the role of vibration damping and vibration isolation together with the vibration isolator to reduce the propagation and influence of the vibration of the centrifuge to the external environment. The integrated steel structure welding machine base supports the whole rotating body (consisting of drum, spiral, differential, etc.) through the bearing seats at both ends, and the split-type sealed stainless steel collecting box covers the entire rotating body and is installed on the machine base. The elastic vibration isolator is installed at the bottom of the base, and the sensor cable is arranged on the bottom of the base. The main and auxiliary motors are arranged at one end of the base, and the inlet pipe is arranged at the other end. The overall layout of the GN makes the machine compact, small footprint and easy to maintain.

 

3, bearing housing

 

The bearing is grouting to ensure the stable operation of the centrifuge. The bearing seat is divided into a large end bearing seat and a small end bearing seat. The bearing housing body is cast by cast iron, the bearing inner ring is respectively mounted on the large end cover, and the whole rotating body is in two main bearings. Internal rotation, lubrication with circulating oil, labyrinth seal on both sides of the bearing.

GN solids control’s oversized drum 30-inch GNLW764A horizontal screw centrifuge is sold to the Australian mining industry. This Australian customer ordered two sets of oversized drum 30-inch GNLW764A horizontal screw centrifuge. The oversized drum 30-inch GNLW764A horizontal snail The centrifuge is an Australian customer who has chosen to cooperate with a number of horizontal and horizontal centrifuge manufacturers at home and abroad.

The oversized drum 30-inch GNLW764A horizontal screw centrifuge produced by GN solids control is widely used in oilfield waste treatment, mining industry and shield waste processing industry. Up to now, the oversized drum 30 inch GNLW764A horizontal screw centrifuge is used in various industries. There have been many successful use cases in the field, and customer evaluation is very high.

 

During the on-site use, the oversized drum 30-inch GNLW764A horizontal screw centrifuge separates the material from the bentonite mud through efficient and continuous separation. After that, the mud water returns to the mud-water loop and is reused. The GNLW764A decanter centrifuge has a large diameter, a high aspect ratio and a separation factor of up to 3000G, which enables a larger throughput and discharges a clearer liquid. GN can provide a flocculation dosing system for chemistry according to customer requirements. The auxiliary decanter centrifuge separates the mud to obtain clean water that can be discharged. GNLW764A horizontal screw centrifuge speed, differential speed, liquid pool depth flexible adjustment to adjust the slag dry humidity.

 

GN can produce various types and length-to-diameter ratio centrifuges to meet the needs of customers in various industries from small to large. Welcome customers to visit GN’s factory to visit and discuss cooperation.

With the maturity of the mud-free market, more and more customers are using GN solid-control vertical cutting dryers. Since the dryer is a high-speed operation equipment like decanter centrifuge, it requires high internal parts and it is especially important to carry out necessary maintenance and maintenance on a regular basis. The following is a brief introduction to the daily maintenance and maintenance of the dryer.

 

After the first use of the dryer for half a month, the new oil should be replaced. Every other month, the oil filter net is cleaned with kerosene once, and the oil contamination and deterioration are checked. The oil change time is determined according to the oil quality. The maximum length cannot exceed six. Months. When replacing the new oil, the oil pipe, oil filter net and fuel tank should be cleaned. If the oil filter net is worn or damaged, replace the new oil filter net and check the tightness of the oil pipe. Check the oil level every two weeks (through the oil mark), and add new oil when the oil quantity is insufficient.

The main motor and oil pump motor are lubricated separately with grease. The motor grease is replenished every 2,500 hours. The grease is recommended according to the manual.

During the working process, if the oil temperature is too high, the oil pressure is low or high, and the oil quality is deteriorated, stop the machine immediately.

Inspection and routine maintenance

Daily routine inspection content:

 

1. Whether the vibration of the dryer is abnormal;
2. The temperature of the main bearing, normal temperature T ≤ 90 ° C;
3. Whether the screws of each component are loose;
4. Whether the slagging and slurrying conditions and the slurry line leak slurry, and whether the inlet and outlet are blocked;
5. Whether the lubrication system has oil leakage or abnormality.

If there is any abnormality in the above inspection, it should be stopped immediately for processing.

 

Check the content regularly:

 

1. Check the tightness of the narrow V-belt every 1000 hours of operation, too loose to adjust; wear should be replaced;
2. Every 1000 hours of operation or excessive vibration, check whether the parts of the equipment are loose, check whether the sensors are connected reliably;
3. Every other month, the oil filter is cleaned with kerosene once, and the oil contamination and deterioration are checked. The oil change time is determined according to the oil quality, and the maximum time cannot exceed six months;
4. Check the oil level every two weeks (through the oil mark), and add new oil when the oil quantity is insufficient;
5. Push and pull the scraper handle every two hours to prevent slag.

In addition, if there are special circumstances, it is necessary to stop the inspection in time to find the cause of the problem and avoid further spread.
