JZB Roots vacuum pump
1. Construction features and working principle of the pump:
Model ZJ Mechanical Booster Pump, also known as a Roots pump, is a volumetric pump.
It employs a pair of rotors, identical and in 8-figure with certain clearance between them
in the pump housing, rotating at the same speed in opposite directions to perform
function of suction and discharge of gas. The 2 rotors are supported by rolling bearings
in the end covers of the pump, rotating at high speed and are kept at a
fixed relative position by a pair of timing gears. The end clearance between rotors and
end covers are fixed by adjustable metal shims between the bearing housings and the
end cover at the fixed end, which ensures one-direction expansion of the rotor when
temperature rises during its operation.
Four sets of inner seals (also known as piston ring) in the 2 end covers prevent lube oil
entering into the pump housing. The shaft seal at the front-end cover, also called as
framework oil seal or shaft seal, prevents leakage of air into the pump housing.
In order to reduce temperature of the pump, all models of pumps (expect the two
smallest models) are equipped with a gearbox cooler and front-end cover cooler.
Power is transmitted through a coupling or V-belt from the motor to the driving shaft of
the pump and then through synchronizing gears to the driven shaft

Можно ли использовать вакуумные насосы для вакуумной упаковки?
Да, вакуумные насосы можно использовать для вакуумной упаковки. Вот подробное объяснение:
Вакуумная упаковка - это метод удаления воздуха из упаковки или контейнера, создающий вакуумную среду. Этот процесс помогает продлить срок хранения скоропортящихся продуктов, предотвратить порчу и сохранить свежесть продукции. Вакуумные насосы играют решающую роль в достижении необходимого уровня вакуума для эффективной упаковки.
Когда речь идет о вакуумной упаковке, обычно используются два типа вакуумных насосов:
1. Одноступенчатые вакуумные насосы: Одноступенчатые вакуумные насосы обычно используются для вакуумной упаковки. В таких насосах для создания вакуума используется одна вращающаяся лопатка или поршень. Они могут достигать умеренных уровней вакуума, подходящих для большинства требований к упаковке. Одноступенчатые насосы имеют относительно простую конструкцию, компактны и экономически эффективны.
2. Пластинчато-роторные вакуумные насосы: Пластинчато-роторные вакуумные насосы - еще один популярный выбор для вакуумной упаковки. В этих насосах для создания вакуума используется несколько лопастей, установленных на роторе. Они обеспечивают более высокий уровень вакуума по сравнению с одноступенчатыми насосами, что делает их подходящими для приложений, требующих более глубокого вакуума. Пластинчато-роторные насосы известны своей надежностью, стабильной работой и долговечностью.
При использовании вакуумных насосов для вакуумной упаковки обычно выполняются следующие действия:
1. Подготовка: Убедитесь, что упаковочный материал, например вакуумные пакеты или контейнеры, подходит для вакуумной упаковки и может выдержать вакуумное давление без утечки. Поместите упаковываемый продукт в соответствующий упаковочный материал.
2. Запечатывание: Правильно запечатайте упаковочный материал, либо с помощью тепловой герметизации, либо с использованием специализированного вакуумного оборудования для герметизации. Это обеспечивает герметичную упаковку продукта.
3. Работа вакуумного насоса: Подключите вакуумный насос к упаковочному оборудованию или непосредственно к упаковочному материалу. Запустите вакуумный насос, чтобы начать процесс вакуумирования. Насос удалит воздух из упаковки, создав вакуумную среду.
4. Контроль уровня вакуума: Контролируйте уровень вакуума в процессе упаковки с помощью манометров или датчиков вакуума. В зависимости от конкретных требований к упаковке, отрегулируйте уровень вакуума соответствующим образом. Цель - достичь желаемого уровня вакуума, подходящего для упаковываемого продукта.
5. Запечатывание и закрытие: После достижения желаемого уровня вакуума полностью запечатайте упаковочный материал, чтобы сохранить вакуумную среду. Это можно сделать с помощью тепловой герметизации упаковочного материала или с помощью специализированных герметизирующих механизмов, предназначенных для вакуумной упаковки.
6. Маркировка и хранение продукта: После герметизации промаркируйте упакованный продукт и храните его надлежащим образом, учитывая такие факторы, как температура, влажность и освещенность, чтобы максимально продлить срок годности продукта.
Важно отметить, что конкретный уровень вакуума, необходимый для вакуумной упаковки, может варьироваться в зависимости от упаковываемого продукта. Для одних продуктов может потребоваться частичный вакуум, а для других - более строгий. Выбор вакуумного насоса и используемых механизмов управления будет зависеть от конкретных требований к вакуумной упаковке.
Вакуумные насосы широко используются в различных отраслях промышленности для вакуумной упаковки, включая производство продуктов питания и напитков, фармацевтику, электронику и многое другое. Они обеспечивают эффективное и надежное средство создания вакуумной среды, помогая сохранить качество продукции и продлить срок ее хранения.
How Do Vacuum Pumps Assist in Freeze-Drying Processes?
Freeze-drying, also known as lyophilization, is a dehydration technique used in various industries, including pharmaceutical manufacturing. Vacuum pumps play a crucial role in facilitating freeze-drying processes. Here’s a detailed explanation:
During freeze-drying, vacuum pumps assist in the removal of water or solvents from pharmaceutical products while preserving their structure and integrity. The freeze-drying process involves three main stages: freezing, primary drying (sublimation), and secondary drying (desorption).
1. Freezing: In the first stage, the pharmaceutical product is frozen to a solid state. Freezing is typically achieved by lowering the temperature of the product below its freezing point. The frozen product is then placed in a vacuum chamber.
2. Primary Drying (Sublimation): Once the product is frozen, the vacuum pump creates a low-pressure environment within the chamber. By reducing the pressure, the boiling point of water or solvents present in the frozen product is lowered, allowing them to transition directly from the solid phase to the vapor phase through a process called sublimation. Sublimation bypasses the liquid phase, preventing potential damage to the product’s structure.
The vacuum pump maintains a low-pressure environment by continuously removing the water vapor or solvent vapor generated during sublimation. The vapor is drawn out of the chamber, leaving behind the freeze-dried product. This process preserves the product’s original form, texture, and biological activity.
3. Secondary Drying (Desorption): After the majority of the water or solvents have been removed through sublimation, the freeze-dried product may still contain residual moisture or solvents. In the secondary drying stage, the vacuum pump continues to apply vacuum to the chamber, but at a higher temperature. The purpose of this stage is to remove the remaining moisture or solvents through evaporation.
The vacuum pump maintains the low-pressure environment, allowing the residual moisture or solvents to evaporate at a lower temperature than under atmospheric pressure. This prevents potential thermal degradation of the product. Secondary drying further enhances the stability and shelf life of the freeze-dried pharmaceutical product.
By creating and maintaining a low-pressure environment, vacuum pumps enable efficient and controlled sublimation and desorption during the freeze-drying process. They facilitate the removal of water or solvents while minimizing the potential damage to the product’s structure and preserving its quality. Vacuum pumps also contribute to the overall speed and efficiency of the freeze-drying process by continuously removing the vapor generated during sublimation and evaporation. The precise control provided by vacuum pumps ensures the production of stable and high-quality freeze-dried pharmaceutical products.
How Do You Choose the Right Size Vacuum Pump for a Specific Application?
Choosing the right size vacuum pump for a specific application involves considering several factors to ensure optimal performance and efficiency. Here’s a detailed explanation:
1. Required Vacuum Level: The first consideration is the desired vacuum level for your application. Different applications have varying vacuum level requirements, ranging from low vacuum to high vacuum or even ultra-high vacuum. Determine the specific vacuum level needed, such as microns of mercury (mmHg) or pascals (Pa), and choose a vacuum pump capable of achieving and maintaining that level.
2. Pumping Speed: The pumping speed, also known as the displacement or flow rate, is the volume of gas a vacuum pump can remove from a system per unit of time. It is typically expressed in liters per second (L/s) or cubic feet per minute (CFM). Consider the required pumping speed for your application, which depends on factors such as the volume of the system, the gas load, and the desired evacuation time.
3. Gas Load and Composition: The type and composition of the gas or vapor being pumped play a significant role in selecting the right vacuum pump. Different pumps have varying capabilities and compatibilities with specific gases. Some pumps may be suitable for pumping only non-reactive gases, while others can handle corrosive gases or vapors. Consider the gas load and its potential impact on the pump’s performance and materials of construction.
4. Backing Pump Requirements: In some applications, a vacuum pump may require a backing pump to reach and maintain the desired vacuum level. A backing pump provides a rough vacuum, which is then further processed by the primary vacuum pump. Consider whether your application requires a backing pump and ensure compatibility and proper sizing between the primary pump and the backing pump.
5. System Leakage: Evaluate the potential leakage in your system. If your system has significant leakage, you may need a vacuum pump with a higher pumping speed to compensate for the continuous influx of gas. Additionally, consider the impact of leakage on the required vacuum level and the pump’s ability to maintain it.
6. Power Requirements and Operating Cost: Consider the power requirements of the vacuum pump and ensure that your facility can provide the necessary electrical supply. Additionally, assess the operating cost, including energy consumption and maintenance requirements, to choose a pump that aligns with your budget and operational considerations.
7. Size and Space Constraints: Take into account the physical size of the vacuum pump and whether it can fit within the available space in your facility. Consider factors such as pump dimensions, weight, and the need for any additional accessories or support equipment.
8. Manufacturer’s Recommendations and Expert Advice: Consult the manufacturer’s specifications, guidelines, and recommendations for selecting the right pump for your specific application. Additionally, seek expert advice from vacuum pump specialists or engineers who can provide insights based on their experience and knowledge.
By considering these factors and evaluating the specific requirements of your application, you can select the right size vacuum pump that meets the desired vacuum level, pumping speed, gas compatibility, and other essential criteria. Choosing the appropriate vacuum pump ensures efficient operation, optimal performance, and longevity for your application.
