Features of the second generation horizontal scraper centrifuge

  The second-generation horizontal scraper discharge centrifuge produced by Hangzhou Huadong Chemical Equipment Industry Co., Ltd. is a new generation of centrifuge designed and manufactured by independent innovation and adopting international advanced technology according to the shortcomings of domestic and foreign users in use and operation. machine. Compared with the existing horizontal scraper unloading centrifuge, the second-generation horizontal scraper unloading centrifuge is more adaptable to the use and operation of relevant professional users, and saves energy, safety, convenience and users. The quality of end products is fully guaranteed, and it is the most complete product of 1250 and 800 horizontal scraper centrifuges in China.

Advantage Analysis

1

Feed limit device

None

Yes

The feeding amount of the first-generation centrifuge is simply set by the time program. Due to the unstable control of the Baume degree of the slurry before feeding, the feeding overflow or insufficient feeding often occurs. The overflowing slurry enters the drain port and is directly discharged, causing waste, and insufficient feeding affects the production capacity, thereby increasing the cost.
The second-generation centrifuge is equipped with this device, and the automatic control of the thickness of the material layer is added on the basis of the time program control of the feeding, which effectively and stably controls the thickness of the material layer, which not only avoids the waste of slurry, but also ensures the production capacity of the centrifuge. At the same time, the newly added yellow pulp outlet can conveniently recycle the overflowing yellow pulp.

2

Scraping mechanism

The scraper shaft seat is short, the scraper shaft is thin, and the work execution oil cylinder is a pull cylinder.

The scraper shaft seat is long, the scraper shaft is thick, and the work execution oil cylinder is a push cylinder.

 

The scraper shaft seat is lengthened and thickened to enhance the rigidity. Compared with the first-generation oil cylinder, the effective thrust of the work execution oil cylinder is increased by 25%, the operation is more stable, and the service life is long.

3

Hydraulic station

No oil cooler, high working oil temperature.

Added oil cooler, low oil temperature.

The first-generation centrifuges are prone to deterioration due to high oil temperature, short oil replacement cycle, and poor pipeline sealing effect. The second-generation centrifuge adds an oil cooler and uses a vane pump. The sealing effect is good, the maximum working pressure can reach 5 MPa, and the service life is long.

4

Main bearing lubrication system

Grease lubricated.

Use thin oil lubrication.

Good lubrication conditions at high speed and long bearing life.

5

Main bearing temperature display and alarm device

None

Yes

The new standard JB/T7220-2006 has been used for centrifuges in my country, and the original JB/T7220-94 standard has been invalidated. The new standard stipulates that the main bearing temperature display and alarm are standard equipment, and the first generation products do not have this device.

6

Feed valve

The size of the feed inlet cannot be adjusted.

Hydraulic feeding valve is selected, and the size of the feeding port can be adjusted freely.

Good applicability to working conditions.

7

Quality Assurance Period

12 months from the factory

Factory 18 or equipment running for 12 months

The whole machine is in good operating condition and the failure rate is low.
