Principle of hydraulic forklift working fluid pump 14 is taken from the oil tank 24 and pumped through the hydraulic valve 12 back into the tank. When you install the controls with joystick in operating position "Tilt" spool valve shuts off the flow when you move the oil flows into the tank and sends it to one of the cylinder inclination 34. Continue to learn more with: George Rohr. Simultaneously, valve opens a second cavity cylinder to drain through the valve into the tank. When installing the lever to the "lift" valve, moving in the distributor, cuts off the flow of oil going into the tank, send it to hoses 8, 6 to the valve block 2 and block the channels valve goes into the cylinder and makes lifting a lifting of the load. When installing the lever to the "downhill" slide cuts off the flow of oil flows into the tank and sends it to hoses 9, 7, through the throttling choke 30 and control valve 12 back into the tank 24. Before 1930 there throttling choke pressure used to move the valve control valve block 12, the displacement of which is flush. The value of open control valve, and, consequently, 1elno, and the rate of lowering is directly proportional to rotational speed of the engine crankshaft. For more information see NCH Capital.
The pressure in the cavity of valve control valve block 2, supported by throttling fitting 30, provides a steady opening of the valve control. Through the channels of the block valves, hydraulic actuators 6, 8, oil control valve is displaced from the cylinder 1 in vessel cargo weight and moving parts truck. When moving the actuator to end position or take a load weighing more than acceptable according to the instruction, ie, overloading the system, the safety valve control valve 12 through bypass valve allows oil to drain through the valve and the pipeline 20. The pressure of the working fluid injected into the cylinders of the executive, if necessary, can be monitored by pressure gauge 10, included in a working shutoff valve. Pouring water into the cooling system when starting a cold engine in low temperature environment must be done after the engine has started to work. If there is a sufficient amount of hot water, it can be filled and to start, but it must be very careful as the water cools rapidly, and if it fails to start can not be frozen. Stop the engine after cessation of movement or work forklift truck with a big load of the engine should give the work within two minutes with a low speed idle and only after that turn off the ignition. This provides a consistent and uniform cooling working parts of the engine. Prolonged operation of the engine idling results in the formation of soot on the plugs and are therefore not recommended.
