HYDRAULIC FILTER ELEMENT PROTECTS HYDRAULIC SYSTEM FROM PARTICLE CONTAMINATION
Hydraulic filter element acts as the core filtration component inside hydraulic filter assemblies. It captures solid particles, metal debris and other impurities suspended in hydraulic oil. Clean hydraulic oil can greatly reduce wear on pumps, valves, motors and cylinders, extending the service life of the whole hydraulic circuit. The filter element adopts pleated fiber or stainless steel mesh material, featuring large dirt holding capacity, stable filtration accuracy and low pressure drop. It can continuously work under high pressure and wide temperature range, suitable for long time continuous operation in heavy duty working conditions. Multiple standard sizes are available for direct replacement of many mainstream filter brands.
Main Application Fields
1. Construction Machinery: Used for excavators, loaders and road rollers to keep hydraulic oil clean on construction sites with heavy dust.
2. Mining Equipment: Applied in underground mining machines to block rock dust and metal powder contamination.
3. Agricultural Machinery: Fits harvesters and large tractors operating in farmland environments.
4. Metallurgical Industry: Works in steel mill hydraulic stations with high temperature and heavy vibration.
5. Marine Machinery: Installed on ship hydraulic systems to resist humidity and corrosive working medium.
Product Introduction
A hydraulic pressure transmitter is an essential sensing component integrated into hydraulic control systems, tasked with detecting real-time fluid pressure and converting physical pressure signals into standard electrical output signals for controllers and monitoring panels. It captures pressure variations inside hydraulic pipelines, oil cylinders and pump stations, enabling operators and automated control systems to track system working status continuously. Built with high-precision pressure sensitive chips and robust stainless steel housing, the transmitter can resist hydraulic impact, oil corrosion and mechanical vibration that commonly occur in hydraulic circuits. Different measurement ranges are available to match low, medium and high pressure hydraulic systems. Featuring high measurement accuracy, fast signal response, long-term stability and strong anti-interference ability, this sensor maintains reliable reading under fluctuating load and harsh site conditions. It supports multiple signal output modes and easy wiring installation, with compact structure suitable for installation in limited space on hydraulic equipment. Proper deployment of pressure transmitters helps achieve closed-loop hydraulic control, timely discover abnormal pressure rise or drop, prevent system overload and reduce unexpected equipment failure risks.
Application Scenarios
Hydraulic pressure transmitters are widely used in mobile machinery, stationary hydraulic stations and automated industrial production lines requiring precise pressure monitoring and feedback control, covering multiple core industries:
1. Construction Engineering Machinery
This is one of the most mainstream application fields. Hydraulic pressure transmitters are installed on excavator main hydraulic circuits, crane lifting hydraulic systems and concrete pump hydraulic drive units. They monitor load pressure in real time during lifting, digging and material conveying operations, support automatic power adjustment and overload protection. Stable pressure feedback guarantees safe operation of heavy construction machines and avoids overload damage to hydraulic pumps and cylinders.
2. Agricultural Machinery Equipment
Adapted to complex and changeable farmland working environments, hydraulic pressure transmitters are fitted on large tractors, combine harvesters and agricultural hydraulic lifting systems. They detect pressure changes of hydraulic lifting and steering mechanisms when working on uneven farmland. The feedback signals help adjust hydraulic output automatically, keep stable operation of farming attachments and improve the intelligence level of modern agricultural machinery.
3. Mining Machinery
For underground mining hydraulic supports, coal mining machines and ore transport hydraulic systems, pressure transmitters endure heavy vibration and dusty working conditions. They continuously monitor the supporting pressure of hydraulic props to guarantee underground workplace safety. Operators can view pressure data remotely and take quick response once pressure abnormality appears.
4. Metallurgical Equipment
Metallurgical hydraulic stations, rolling mill hydraulic clamping systems and metal forging hydraulic presses adopt pressure transmitters for closed-loop pressure control. They withstand high ambient temperature and oil pollution on site, maintaining precise pressure control during metal forming and clamping processes to secure consistent product quality.
5. Marine Hydraulic Systems
Onboard deck machinery, ship crane hydraulic power units and rudder hydraulic control systems use hydraulic pressure transmitters. The corrosion-resistant structure adapts to high humidity and salt spray marine environment. Real-time pressure monitoring ensures stable power transmission and reliable safety protection for marine hydraulic equipment.
