Points for attention in the installation of solenoid valves of injection molding machines

an of valve components, Zhao Ming, deputy general manager of the company, told that the installation types include pipe type, plate type, superimposed type and embedded type, which are different, and the installation methods and requirements are also ignored

superposition integration is to make the valve body into a rectangular shape with standard size, stack the used components on the seat plate, and then tighten it with a pull rod. Its characteristic is that it fundamentally eliminates the connecting pipeline between the valves, so the system is more simple and centralized. The three features and three functions of Jinan gold assay electronic creep endurance tester are compact, and the system assembly is flexible, which is convenient for the improvement of the oil circuit. (tubular and plate valves are less used now.)

the installation method and requirements of hydraulic components can refine the grain:

are described in detail in the product manual. The components have passed the quality inspection and performance test before leaving the factory, and the oil ports are sealed with plastic plugs. A certain number of enclosed sealing spare parts are packed and shipped in plastic bags. Before use, check whether the certificate of conformity, instructions and spare parts are complete, and check whether there is poor packaging, damage or foreign matter, and whether the oil port is opened. It is best to clean with kerosene once before installation. Attention should also be paid during installation: do not connect the oil ports incorrectly (generally, all oil ports of components are marked with words or codes); When installing the motorized control valve pair, be sure to pay attention to the stroke of the cam or cylinder block and the distance between the cam and the valve, so as to avoid damage during commissioning; When installing connecting elements with flanges, the connecting screws should be properly screwed. If they are tightened too tightly, the sealing will be poor; Some kinds of holes have been opened for manufacturing and installation, and the useless ones should be blocked after installation; After installation, the spare sealing traps of various components should be kept well for replacement during maintenance. When installing the hydraulic valve of the imported metering pump, the following points must also be paid attention to: (1) before installation, carefully check the certificate of conformity and review the instructions for the unpacked hydraulic valve parts, and verify the pressure and sealing of Yan if necessary. (2) Make clear the orientation of the oil inlet and return port of the valve. (3) If there are no special regulations on the installation position of the valve, it should be installed at a position convenient for use and maintenance. The installation of direction control valve should be horizontal. (4) For the valve parts installed with flanges, the screws should not be tightened too tightly, so as to avoid maintaining a gap of about o.5mm and eliminate the fault and poor sealing. (5) Some valves are provided with holes convenient for manufacturing and installation, and the useless holes should be blocked after installation. (6) Some valves cannot be purchased during installation, and it is allowed to use hydraulic valves with a flow rate exceeding 40% of the rated flow
