As a professional manufacturer and supplier of quantitative control boxes, as well as a manufacturer and supplier of integrated explosion-proof quantitative filling systems, we have been deeply involved in the research, development, production, and supply of filling equipment for special working conditions for many years. Relying on our mature technical strength and rich industry experience, we have customized an explosion-proof quantitative filling system suitable for dust-explosive environments for SA, a globally leading special chemicals enterprise, successfully addressing the safety and process pain points in its quantitative filling process for spraying oil. The following is a detailed analysis of the application case.
1. Problem Presentation
As a globally leading specialty chemicals enterprise, SA Company occupies a leading position in the research, development, and production of system products such as bonding and sealing in the fields of construction and industrial manufacturing. In the production processes related to the quantitative filling of spraying oil, it faces the dual challenges of prominent safety hazards and process bottlenecks, urgently requiring professional quantitative control box manufacturers and suppliers to provide integrated solutions.
When spraying oil is mixed with substances such as the company’s main adhesive sealing products for construction, concrete solutions, etc., it is extremely prone to generating combustible dust. After this type of dust reaches a specific concentration in the air, if it comes into contact with a tiny electrical spark or the high-temperature surface of equipment, it is highly likely to trigger an explosion accident, seriously threatening the safety of operators’ lives and the integrity of production facilities. At the same time, the traditional manual quantitative filling model has problems such as insufficient measurement accuracy, low production efficiency, and prominent human operation errors, which cannot meet the strict process standard requirements of enterprises for the quantitative filling of spraying oil. Therefore, there is an urgent need for quantitative control box manufacturers and suppliers to provide customized filling systems that are accurate, intelligent, and explosion-proof.
2. Requirements Analysis
Combining with the actual pain points in production, SA Company has clearly put forward core requirements to us (manufacturer and supplier of quantitative control boxes, manufacturer and supplier of integrated explosion-proof quantitative filling systems), requiring a set of explosion-proof quantitative filling systems suitable for dust-explosive environments. This system must simultaneously meet the following core requirements to ensure safe, accurate, and efficient operation, while also requiring us to give full play to the advantages of the manufacturer to ensure the quality of the equipment and customized adaptability:
- Safety Requirements: The system shall have perfect explosion-proof performance, be able to operate stably and safely in explosive dust environments generated by the mixture of sprayed oil and other substances, fully comply with relevant national and industry explosion-proof safety regulations, and as a manufacturer of quantitative control boxes, we need to ensure that the explosion-proof grade of the core control components meets the standard.
- Measurement requirement: Achieve precise quantitative filling of spraying oil, with measurement accuracy strictly conforming to the control standards of the production process for product quality, effectively avoiding issues such as raw material waste or product non-conformance caused by measurement errors, and demonstrating our technical strength in precise control as a supplier of quantitative control boxes.
- Control Requirements: The system shall integrate automated control functions, enabling automatic start and stop, real-time flow monitoring, and precise quantitative control during the spraying oil filling process, comprehensively replacing the traditional manual operation mode, enhancing production efficiency and operational standardization, and leveraging our manufacturer’s advantages in equipment integration and intelligent control.
- Compatibility Requirements: The system must be well compatible with existing production equipment such as on-site power pumps. If on-site power pumps are installed, it is necessary to ensure that the pump power matches the system parameters. Meanwhile, key aspects such as system power supply and signal transmission must achieve full-process compatibility to ensure the overall operational stability of the system. As the supplier, we will provide adaptation and debugging services throughout the process.
3. Challenge Analysis
3.1 Environmental Explosion-Proof Challenges
The dust generated by the mixing of spraying oil and the main chemical substances of SA Company belongs to a typical combustible dust environment, which places extremely high requirements on the explosion-proof grade and protective measures of electrical equipment and control devices in the system. As a manufacturer of quantitative control boxes, we need to overcome the difficulties in the explosion-proof design of core components. If the explosion-proof performance of the equipment fails to meet the regulatory standards, even a slight electrical spark or a slight high temperature on the equipment surface may trigger a dust explosion, resulting in a major safety accident. This is also a core test of our manufacturer’s technical strength.
3.2 Measurement Accuracy Challenges
The filling process of spraying oil requires a high level of quantitative accuracy, while the measurement accuracy of turbine flow meters is affected by multiple factors such as medium viscosity, flow rate stability, and equipment installation technology. In a dust-explosive environment, the internal components of the flow meter are prone to problems such as wear and laggy due to dust intrusion, directly leading to an increase in measurement error and failing to meet the quantitative control requirements of the production process. As the manufacturer of the quantitative control box, we need to optimize the control algorithm and equipment adaptability to ensure measurement accuracy.
3.3 System Compatibility Challenges
If a power pump is installed on-site, it is necessary to strictly ensure that the quantitative control system precisely matches the pump body power (not exceeding 4Kw); otherwise, malfunctions such as control failure and equipment overload may easily occur, affecting the normal operation of production. Meanwhile, key aspects such as system power supply (control box 220VAC, solenoid valve and flowmeter 24VDC) and signal transmission (pulse signal of turbine flowmeter compatible with control box) need to achieve seamless compatibility to ensure the long-term stable operation of the system. As the supplier, we will follow up on-site adaptation throughout the process to resolve compatibility issues.
4. Solution Design
In response to the core needs and various challenges faced by SA Company, as a professional manufacturer and supplier of quantitative control boxes, as well as an integrated explosion-proof quantitative filling system manufacturer and supplier, we have given full play to our integrated advantages in R&D, production, and supply, and designed an integrated quantitative filling system centered on explosion-proof quantitative control boxes, equipped with explosion-proof turbine flow meters and explosion-proof solenoid valves. From the three core dimensions of environmental adaptation, measurement accuracy, and system linkage, we comprehensively address production pain points and provide one-stop services for customized R&D, production, installation, and commissioning throughout the process.
4.1 Explosion-proof Design: Strengthening the Intrinsic Safety Defense Line
As a manufacturer of quantitative control boxes, we adopt explosion-proof design for all electrical equipment in the system, fully meeting both dust explosion-proof and gas explosion-proof standards. The core explosion-proof quantitative control box is independently developed and produced by us, with controllable quality. The explosion-proof control box uses a cast aluminum enclosure, which has undergone special sealing and explosion-proof treatment, effectively isolating internal electrical sparks from the external dust environment and eliminating potential explosion hazards. The explosion-proof turbine flowmeter and explosion-proof solenoid valve both adopt dedicated explosion-proof structural design, preventing sparks generated during medium flow and valve body operation from triggering explosion accidents. In addition, the system wiring and interface parts have all undergone professional explosion-proof sealing treatment, effectively preventing dust from intruding into the equipment through cable inlets, completely eliminating various explosion risks at the hardware level, ensuring production safety, and fully demonstrating our manufacturer’s technical advantages and quality control capabilities.
4.2 Measurement and Control: Achieving the Synergy of Precision and Intelligence
- Explosion-proof Turbine Flowmeter: As the supplier, we have carefully selected an explosion-proof turbine flowmeter with a DN25 caliber and a measurement accuracy of ±0.5%, which is suitable for the working conditions. The material is SS304 stainless steel, ensuring corrosion resistance in the spraying oil medium while also providing sufficient structural strength and wear resistance. The device can output real-time flow data accurately to our self-produced explosion-proof quantitative control box through pulse signals, providing reliable data support for quantitative control; its applicable temperature range (-20°C – 180°C) and pressure rating (6.3 MPa) can fully meet the filling requirements of spraying oil under different working conditions.
- Explosion-proof Quantitative Control Box: As our core production product, the explosion-proof quantitative control box is the core control unit of the system, equipped with a touchscreen operating interface. It is independently developed by us with a built-in dedicated control program, capable of receiving in real-time the pulse signals transmitted by the turbine flowmeter, accurately calculating the real-time flow and cumulative flow. When the cumulative flow reaches the pre-set quantitative value, it automatically issues control commands to close the solenoid valve, achieving precise quantitative filling. Meanwhile, the control box can flexibly set parameters such as filling time (not less than 10s to avoid measurement errors caused by excessive flow velocity) and start-stop logic, fully adapting to the rhythm of on-site production processes, demonstrating our customization capabilities as a quantitative control box manufacturer.
4.3 System Linkage: Achieve full-process automated control
If a power pump is installed on-site, the explosion-proof quantitative control box produced by our company can control the start and stop of the pump body through a dedicated electrical interface, ensuring that the pump body power (≤4Kw) precisely matches the system parameters and guaranteeing the coordinated operation of the equipment. After the filling process starts, the control box first controls the pump body to start; after the medium flow rate reaches a stable state, it then opens the solenoid valve to start filling. When the cumulative flow reaches the pre-set value, it first closes the solenoid valve to cut off the medium flow, and then stops the operation of the pump body, effectively avoiding measurement errors caused by the idling of the pump body or the backflow of the medium and improving the filling accuracy.
The solenoid valve is an explosion-proof product with a DN25 specification and 24VDC power supply, which is supplied by our strictly screened suppliers. It is made of SS304 stainless steel and uses a threaded connection method, facilitating on-site installation and maintenance. The equipment has fast response characteristics and can quickly cut off the medium flow after the control box issues a closing command, further ensuring the accuracy of quantitative filling. As an integrated supplier, we fully control the quality and compatibility of equipment matching throughout the process.
