Hydraulic system installation, debugging and maintenance (2),Quality inspection of pipes and joints, the pressure level of pipe joints should meet the design requirements,The material, diameter, wall thickness of the pipe, the model specification and processing quality of the joint must meet the design requirements. The tubes used must not be defective. The following exceptions are not allowed to be used,When using curved pipes, the following exceptions are not allowed,The joints used must not be defective.

Hydraulic system schematic diagrams, electrical schematic diagrams, piping layout diagrams, hydraulic components, auxiliary parts, pipe fitting lists and related component samples, etc., should be prepared in full so that engineers and technicians can be familiar with and study the specific content and technical requirements one by one.

Application of Cartridge Valve in Hydraulic System，Through more complex combinations, more hydraulic valve functions can be achieved. Through the combination, the cartridge valve can be used as a pressure control valve (sequence valve, pressure reducing valve), flow control valve (one-way throttle valve, throttle valve), directional control valve (speed control valve, hydraulic control one-way valve, two Two-way reversing valve, etc.) and compound valve.At present, the cartridge valve has the following series: K series cartridge valve, L series cartridge valve, TJ series cartridge valve, Z series cartridge valve.
