two. 2X dual-stage rotary collection vacuum pump, perform in temperature 5ºC~40ºC.
three. 2X dual-stage rotary collection vacuum pump inlet constant-time shall not exceed 3min.

Guidelines :

one. Check out the oil level, it is highly recommended to fill the oil to the middle of the oil mark when the pump is stopped. If it is also minimal, the exhaust valve cannot act as an oil seal and impact the degree of vacuum. If it is also substantial, it may result in gasoline injection when commencing to open to the environment. In the course of procedure, the oil amount has increased, which is a standard phenomenon. Oil generation Use the cleanse vacuum pump oil of the specified manufacturer and insert it from the oil filling hole. After refueling, the screw plug ought to be screwed on. The oil ought to be filtered to avoid debris from getting into and blocking the oil holes.
2. The 2XZ rotary vane vacuum pump can be began at 1 time beneath the ambiance or any vacuum degree. If the pump port is related with a solenoid valve, it must act at the identical time as the pump.
3. When the ambient temperature is also substantial, the temperature of the oil will rise, the viscosity will fall, and the saturated vapor stress will improve, which will cause the supreme vacuum to fall, specially the overall pressure calculated with a thermocouple. This sort of as strengthening air flow and warmth dissipation, or enhancing pump oil overall performance, the ultimate vacuum can be enhanced.
4. Verify that the final vacuum of the 2XZ rotary vane vacuum pump is based on the compression mercury vacuum gauge. If the gauge is entirely pre-pumped, the pump temperature is stable, and the pump port is immediately linked to the gauge. It will achieve inside of thirty minutes of procedure. Greatest vacuum. The worth measured by the total strain gauge is related to the error of the pump oil, the vacuum gauge, and the gauge. Sometimes the error can be very huge and can only be employed as a reference.
5. If the relative humidity is higher, or the pumped gasoline consists of a lot more condensable steam, the gas ballast valve ought to be opened following the pumped container is linked, and the fuel ballast valve should be closed after 20-forty minutes of operation. Just before stopping the pump, the gas ballast valve can be opened for thirty-moment no-load motion to increase the existence of the pump oil.
six. Oil selection for 2XZ rotary vane vacuum pump: The viscosity of the pump oil has an effect on the beginning energy and the greatest vacuum of the pump. When the viscosity is large, it is advantageous to the vacuum degree, but the starting power is greater. The saturated vapor stress of the oil at the pump temperature will affect the greatest whole strain of the pump, the decrease the greater.

Types of vacuum pumps

A vacuum pump is a device that draws gas molecules from a sealed volume and leaves a partial vacuum in its wake. Its job is to create a relative vacuum within a specific volume or volume. There are many types of vacuum pumps, including centrifugal, screw and diaphragm.
Vacuum Pump

Forward centrifugal pump

Positive displacement centrifugal vacuum pumps are one of the most commonly used pump types in the oil and gas industry. Their efficiency is limited to a range of materials and can handle relatively high solids concentrations. However, using these pumps has some advantages over other types of pumps.
Positive displacement pumps have an enlarged cavity on the suction side and a reduced cavity on the discharge side. This makes them ideal for applications involving high viscosity fluids and high pressures. Their design makes it possible to precisely measure and control the amount of liquid pumped. Positive displacement pumps are also ideal for applications requiring precise metering.
Positive displacement pumps are superior to centrifugal pumps in several ways. They can handle higher viscosity materials than centrifuges. These pumps also operate at lower speeds than centrifugal pumps, which makes them more suitable for certain applications. Positive displacement pumps are also less prone to wear.
Positive displacement vacuum pumps operate by drawing fluid into a chamber and expanding it to a larger volume, then venting it to the atmosphere. This process happens several times per second. When maximum expansion is reached, the intake valve closes, the exhaust valve opens, and fluid is ejected. Positive displacement vacuum pumps are highly efficient and commonly used in many industries.

Self-priming centrifugal pump

Self-priming centrifugal pumps are designed with a water reservoir to help remove air from the pump. This water is then recirculated throughout the pump, allowing the pump to run without air. The water reservoir can be located above or in front of the impeller. The pump can then reserve water for the initial start.
The casing of the pump contains an increasingly larger channel forming a cavity retainer and semi-double volute. When water enters the pump through channel A, it flows back to the impeller through channels B-C. When the pump is started a second time, the water in the pump body will be recirculated back through the impeller. This recycling process happens automatically.
These pumps are available in a variety of models and materials. They feature special stainless steel castings that are corrosion and wear-resistant. They can be used in high-pressure applications and their design eliminates the need for inlet check valves and intermediate valves. They can also be equipped with long intake pipes, which do not require activation.
Self-priming centrifugal pumps are designed to run on their own, but there are some limitations. They cannot operate without a liquid source. A foot valve or external liquid source can help you start the self-priming pump.

Screw Pump

The mechanical and thermal characteristics of a screw vacuum pump are critical to its operation. They feature a small gap between the rotor and stator to minimize backflow and thermal growth. Temperature is a key factor in their performance, so they have an internal cooling system that uses water that circulates through the pump’s stator channels. The pump is equipped with a thermostatically controlled valve to regulate the water flow. Also includes a thermostatic switch for thermal control.
Screw vacuum pumps work by trapping gas in the space between the rotor and the housing. The gas is then moved to the exhaust port, where it is expelled at atmospheric pressure. The tapered discharge end of the screw further reduces the volume of gas trapped in the chamber. These two factors allow the pump to work efficiently and safely.
Screw vacuum pumps are designed for a variety of applications. In some applications, the pump needs to operate at very low pressures, such as when pumping large volumes of air. For this application, the SCREWLINE SP pump is ideal. Their low discharge temperature and direct pumping path ensure industrial process uptime. These pumps also feature non-contact shaft seals to reduce mechanical wear. Additionally, they feature a special cantilever bearing arrangement to eliminate potential sources of bearing failure and lubrication contamination.
Screw vacuum pumps use an air-cooled screw to generate a vacuum. They are compact, and clean, and have a remote monitoring system with built-in intelligence. By using the app, users can monitor pump performance remotely.
Vacuum Pump

Diaphragm Pump

Diaphragm vacuum pumps are one of the most common types of vacuum pumps found in laboratories and manufacturing facilities. The diaphragm is an elastomeric membrane held in place around the outer diameter. While it is not possible to seal a diaphragm vacuum pump, there are ways to alleviate the problems associated with this design.
Diaphragm vacuum pumps are versatile and can be used in a variety of clean vacuum applications. These pumps are commercially available with a built-in valve system, but they can also be modified to include one. Because diaphragm pumps are so versatile, it’s important to choose the right type for the job. Understanding how pumps work will help you match the right pump to the right application.
Diaphragm vacuum pumps offer a wide range of advantages, including an extremely long service life. Most diaphragm pumps can last up to ten thousand hours. However, they may be inefficient for processes that require deep vacuum, in which case alternative technologies may be required. Additionally, due to the physics of diaphragm pumps, the size of these pumps may be limited. Also, they are not suitable for high-speed pumping.
Diaphragm vacuum pumps are a versatile subset of laboratory pumps. They are popular for their oil-free construction and low maintenance operation. They are available in a variety of styles and have many optional features. In addition to low maintenance operation, they are chemically resistant and can be used with a variety of sample types. However, diaphragm pumps tend to have lower displacements than other vacuum pumps.

Atmospheric pressure is a key factor in a vacuum pump system

Atmospheric pressure is the pressure created by the collision of air molecules. The more they collide, the greater the pressure. This applies to pure gases and mixtures. When you measure atmospheric pressure, the pressure gauge reads about 14.7 psia. The higher the pressure, the greater the force on the gas molecules.
The gas entering the vacuum pump system is below atmospheric pressure and may contain entrained liquids. The mechanism of this process can be explained by molecular kinetic energy theory. The theory assumes that gas molecules in the atmosphere have high velocities. The resulting gas molecules will then start moving in random directions, colliding with each other and creating pressure on the walls of the vacuum vessel.
Atmospheric pressure is a critical factor in a vacuum pump system. A vacuum pump system is useless without proper atmospheric pressure measurement. The pressure in the atmosphere is the total pressure of all gases, including nitrogen and oxygen. Using total pressure instead of partial pressure can cause problems. The thermal conductivity of various gases varies widely, so working at full pressure can be dangerous.
When choosing a vacuum pump, consider its operating range. Some pumps operate at low atmospheric pressure, while others are designed to operate at high or ultra-high pressure. Different types of pumps employ different technologies that enhance their unique advantages.
Vacuum Pump

The screw pump is less efficient in pumping gases with smaller molecular weight

Vacuuming requires a high-quality pump. This type of pump must be able to pump gas of high purity and very low pressure. Screw pumps can be used in laboratory applications and are more efficient when pumping small molecular weight gases. Chemical resistance is critical to pump life. Chemical resistant materials are also available. Chemically resistant wetted materials minimize wear.
Gear pumps are more efficient than screw pumps, but are less efficient when pumping lower molecular weight gases. Gear pumps also require a larger motor to achieve the same pumping capacity. Compared to gear pumps, progressive cavity pumps also have lower noise levels and longer service life. In addition, gear pumps have a large footprint and are not suitable for tight spaces.
Progressive cavity pumps have two or three screws and a housing and side cover. They are also equipped with gears and bearings. Their mechanical design allows them to operate in high pressure environments with extremely low noise. The progressive cavity pump is a versatile pump that can be used in a variety of applications.
Dry screw compressors have different aspect ratios and can operate at high and low pressures. The maximum allowable differential pressure for screw compressors ranges from 0.4 MPa for 3/5 rotors to 1.5 MPa for 4/6 rotors. These numbers need to be determined on a case-by-case basis.
