Застосування вакуумних насосів Roots

With the advancement of vacuum application, there are numerous sorts of Roots vacuum pump. The roots vacuum pump’s pumping velocity has transformed from a couple of liters for every second to several thousand and a large number of liters every second.

As per the Roots vacuum pump’s working standard, the roots vacuum pump can be fundamentally separated into two kinds, specifically gas catch pump and gas move pump. With the vacuum innovation in the creation and logical exploration, the weight scope of its application is getting more extensive and more extensive.

Most vacuum pumps should be made out of a few roots vacuum pumps to pump together to meet the creative and logical examination measures’ prerequisites.

Since the working weight territory engaged with the vacuum application division is vast, it is difficult to finish any Roots vacuum pump. It is reasonable for all working weight ranges. Various sorts of Коріння вакуумних насосів must be utilized by multiple working weight ranges and diverse working prerequisites. To utilize helpfully and address the issues of different vacuum measures, separate roots vacuum pumps are consolidated by their presentation necessities and applied as units.

The generally used roots vacuum pumps incorporate dry screw vacuum pump, water ring pump, responding pump, slide valve pump, rotating vane pump, roots pump, and dispersion pump. These pumps are the necessary primary pumps in utilizing vacuum innovation in different enterprises of the public economy.

As of late, with the continuous and fast advancement of China’s economy, the downstream application industry identified with roots vacuum pumps keeps a quick development force. Simultaneously, under the joint draw of the nonstop extension of the application field of Roots vacuum pump and different components, the roots vacuum pump industry in China has accomplished a continued, steady and fast turn of events.

Operating Principle and Особливості гри:

The series ZJP roots vacuum pump is with overflow valve. The figure-of-eight rotors are counter-rotating at a regular speed in the pump housing for suction and exhaust of gas. Two rotors are supported by two bearings and synchronized by a gear, which ensures these two rotors in certain relative positions. They are near to one another also to the housing without actual contacting, so lubrication is unnecessary in the working housing. The carefully balanced operating parts and high precision bevel wheels ensue the pump be operated stably and continually under the condition of high-pressure difference. Dynamic seal part use our patent technology and imported oil seals, the vibration amount of shaft on the shaft seals is handled to less than 0. 02mm.

A gravity valve is installed between the suction and exhaust part of the pump. The function of the gravity valve is as follows, when the pressure difference between the suction and exhaust part is over the weight of the valve, the valve opens automatically, which makes the pressure difference always keep in a fixed controllable value, the value is the allowable highest pressure difference to ensure the pump work normally and in order that in fact , the roots vacuum pump with overflow valve is a form of overload self-protective pump.

Series ZJP roots vacuum pump with overflow valve has substantially higher speed at relatively lower inlet pressure and it is possessed overload self-protective function. Because it is a pump of dry clearance seal construction, if a specific pumping speed rate and an ultimate vacuum need to be obtained, it is necessary to supply a lower inlet pressure for reducing the back flow, therefore , a pump must be backed in use, roots vacuum pump should be started soom after its inlet pressure reaches a permissible value for economization.

It is permit to select different sorts of pump as the backing pump for factual requirements, such as oil seal pump and liquid ring vacuum pump. When pumping the gas containing large amount of vapor, the liquid ring vacuum pump is the ideal backing pump.
