Chemical Industry-Used SAM Plastic Resin Transfer Reactor Kettle Pressure-Boosting Gear Pump

I. Application

In chemical production, the transfer of SAM plastic resin often requires equipment that can withstand high temperatures, high pressures, and high viscosity conditions. The bottom-mounted pressure-boosting gear pump, due to its special structure and materials, is able to meet these requirements, ensuring smooth transfer and pressure boosting of the resin.

II. Working Principle

The working principle of the reactor kettle pressure-boosting gear pump is mainly based on the meshing and rotation of gears. When two gears mesh and rotate within the pump casing, the space between them changes, creating suction and pressure, which draws the resin from the bottom of the vessel and outputs it through the pump body. This type of pump is a volumetric forced transfer pump, and its output flow can be adjusted by changing the pump's rotational speed.

III. Main Features

High Temperature and High Pressure: The reactor kettle pressure-boosting gear pump can withstand temperatures up to 350°C and pressures up to 40MPa, meeting the high temperature and high pressure demands of SAM plastic resin transfer.

High Viscosity: The pump is capable of transferring resin with a viscosity of up to 40,000Pa•s, demonstrating strong adaptability.

Stable Flow: Due to the precise meshing and rotation of the gears, the pump's output flow is very stable, achieving near-linear flow output.

Excellent Materials: Key components such as the pump body, gears, and bearings are made of high-quality materials such as stainless steel, alloy steel, and corrosion-resistant alloys, providing corrosion resistance, wear resistance, and long service life.

Sealing Structure: It adopts a melt dynamic seal + gland packing seal or high-temperature-resistant gland packing seal to ensure no leakage during pump operation.

IV. Main Parameters

Here are some common parameters of the bottom-mounted pressure-boosting gear pump for reference:

Medium Viscosity: 0.0001Pa.s to 40,000Pa•s

Suction Pressure: Vacuum (-0.05 to -0.09MPa) to 4MPa

Discharge Pressure: 0 to 35MPa

Operating Differential Pressure: ≤25MPa

Operating Temperature: ≤350°C

Heating Methods: Jacketed heating with heat transfer medium / flow path heating / electric heating, etc.

V. Selection Suggestions

When selecting a bottom-mounted pressure-boosting gear pump, the following factors should be considered:

Characteristics of the Transfer Medium: Including viscosity, temperature, corrosivity, etc., to ensure that the selected pump can adapt to the operating conditions.

Flow and Pressure Requirements: Determine the required flow and pressure range based on production process requirements.

Pump Materials and Structure: Select appropriate materials and structures based on the corrosivity of the medium and the severity of the operating conditions.

Brand and Quality: Choose well-known brands and reliable pump products to ensure the stability and service life of the equipment.

VI. Operation and Maintenance

Pre-operation Inspection: Before use, inspect whether the pump components are intact, whether the fasteners are loose, whether the lubrication is good, etc.

Monitoring During Operation: Monitor the pump's flow, pressure, temperature, and other parameters during operation to ensure normal operation of the equipment.

Regular Maintenance: Regularly clean, lubricate, and inspect the pump, and replace worn parts in a timely manner to extend the service life of the equipment.

In summary, the chemical industry-used SAM plastic resin transfer reactor kettle pressure-boosting gear pump is an efficient and reliable equipment that can meet the transfer demands under high temperature, high pressure, and high viscosity conditions. During selection and use, full consideration should be given to the characteristics of the medium and process requirements to select the appropriate pump product and maintenance method.
