Single-stage regulator circuit in quantitative pump system, system pressure relief valve set pressure from decided. When the system pressure reaches the setting value relief valve, relief valve to open, the excess oil back to the tank through the relief valve. This circuit less efficient 100 tons of hydraulic jacks specifications, generally used for flow is not the occasion. It is a hydraulic system is widely used in the circuit. When the multi-stage regulator circuit when the system needs a multi-stage pressure control 100 t hydraulic jacks where the production, can be such a loop. When the three-way solenoid valve is energized 1DT system as it is set by the pressure relief valve 2 work, when 2DT energized, the system as it is set by a pressure relief valve 3 job. When 1DT, 2DT not energized, the system pressure relief valve as it is set by the pressure of 1 to work. 2,3 relief valve must be higher than the set pressure of the relief valve 1 to be small. The hydraulic system (2) oil pressure circuit with a single pump, the working pressure in the main oil on the road tends to be high, and the lower the required clamping and lubrication pressure branch circuit, then the circuit can be reduced. For separate hydraulic jack at the time of installation should pay attention to what aspects of it, its installation requirements and what it? Some customers of separate hydraulic jack to use long after the inevitable change some wearing parts to keep 100 tons of hydraulic jacks, it is bound to disassemble, install separate hydraulic jacks, as the saying goes, the mountain is easy, down hard; separate hydraulic jacks Good demolition, then install it on the big difficulty so little, and today small to share with you some of the installation requires separate hydraulic jack, hoping to clients and friends of separate hydraulic jack installation help. Installation requires separate hydraulic jacks summed up with the following advantages: 1, the central axis of the separate hydraulic jacks should be concentric with the center line of the load force, in order to avoid lateral pressure, lateral force is easy to wear and piston seals damage. Of separate hydraulic jacks moving objects, when the cylinder is installed parallel with the moving object in the direction of movement of different track surface, which is parallel to the degree usually not more than 0.05mm / n. 2, install separate hydraulic jacks gland screws, Tighten the extent to guarantee the full stroke of the piston can move freely, without arrest and the severity of the phenomenon of uneven appropriate. Screws too tight, it will increase the resistance, accelerated wear; too loose can cause leakage. 100 tons of hydraulic jacks where production, 100 tons hydraulic jacks, hydraulic force provided by the Texas Lu Lu force hydraulic machinery plant. Texas Lu force hydraulic machinery plant (www.luliyeya.com) strong, credible, in Dezhou hydraulic machinery and components industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Lu Hydraulic and you work into the brilliant, for a better future!
