Ningbo, Zhejiang province, China: - Although there are hundreds of suppliers of hydraulic valve blocks online, finding the best company has been disconcerting. In order to solve this problem, Ningbo Zhenhai Guilong manifold blocks Machinery Co., Ltd. provides a wide variety of hydraulic valve Blocks, which are used for hydraulic modular valves or hydraulic cartridge valves as valve base plates or valve cavities for integrated hydraulic systems. Generally recognized as the best manufacturer of hydraulic assemblies, the company also offers hydraulic sandwich assemblies, cartridge assemblies hydraulic sub-assemblies, assembly covers, valve adapters and custom assemblies to the global market. The company prides itself on offering products manufactured according to DIN 24340, ISO 4401, Cetop standards. The aluminum seat of hydraulic valve provided by our company is made of aluminum material, usually 6061-t6 or 7075-t6 code as the main material, which can withstand more than 20Mpa (200bar) of hydraulic pressure in the hydraulic system. Hydraulic cartridge blocks are manufactured to customer requirements for use in hydraulic systems. The maximum hydraulic pressure is usually about 25Mpa and 250bar is aluminum alloy material.Material information comes to manifold blocks

2. Installation position of filter in hydraulic system
Installed in the suction port of the pump
Filter is required to have a large flow capacity and small resistance, the flow should be more than twice the pump flow, to prevent cavitation phenomenon. Mainly used to protect the hydraulic pump, but the wear products generated in the hydraulic pump will still enter the system. Generally, a filter with lower filtering accuracy is used.
Installed at the oil outlet of the pump
The filter should be able to withstand the working pressure and impact pressure on the oil road; In order to prevent the filter blockage caused by hydraulic pump overload or damage to the filter element, the pressure oil road should be parallel side valve or series one indicating device. This method is often used for filtering precision requirements of the system and servo valve and speed control valve, in order to ensure their normal work.Material information comes to manifold blockS
Installed on the oil return circuit
These are called return oil filters, which remove metal and rubber particles from the worn hydraulic components to protect the cleanliness of the fluid flowing back to the tank. Allow the use of lower strength and stiffness of the filter filter; In order to prevent the system pressure rise caused by the blockage of the filter element, a one-way valve in parallel with the filter is required to act as a bypass valve.
Independent bypass filter
In the hydraulic system of large machinery, independent filtration system composed of hydraulic pump and filter can be specially set up, which can continuously remove impurities in the system and improve the cleanliness of oil. Such as oil filter car.Material information comes to manifold blockS
3. Filter selection steps
Clear design requirements: clear system pressure, flow, hydraulic oil grade, working temperature;
Determine the filtration accuracy level required by the system;
According to the filter in the hydraulic circuit installation position and the use of pressure to determine the type of filter;
Determine the size of the specification: pre-select according to experience or pre-selected line chart, and then calculate its initial pressure drop. If the value is greater than the recommended value above, it is necessary to select a filter with a larger flow specification.Material information comes to manifold blockS
Determine the filter pollution signal mode, bypass, etc.
4. Precautions during use
Filters should not reverse oil flow, reliable measures should be in place to ensure workers do not misconnect.
After the filter element is polluted, the pressure difference flowing through the filter may open the bypass valve, resulting in incomplete flow filtration of oil, or even collapse of the filter screen. Therefore, the filter must be set up with visual or electrical alarm. Provide accurate and reliable indication as to whether the filter element needs to be replaced. For the filter whose installation position is not convenient for the operator to observe, electric alarm is preferred.
Because the filter element is a wearing part, the design should be set aside to repair the replacement of the filter element space.Material information comes to manifold blockS
Stainless steel filter element can be reused, but considering that the cleanliness of the filter element after cleaning is difficult to reach the standard, it is recommended to choose disposable paper filter element.
