One. The left oil path when two-way and variable pump is the return circuit that uses inverting of two-way and variable pump when high pressure, piston of hydraulic pressure crock moves right, right now D of a powerful person is in left. When the right pipeline of variable pump is high pressure, towards the left of piston of hydraulic pressure crock moves, right now, d of a powerful person is in right, make hydraulic pressure crock left the D of a powerful person of classics of redundant oil fluid of antrum and oil sump tank of P of back pressure a powerful person. Pump Ⅱ is filling oil pump, force of filling oil pressure of setting of Y of overflow a powerful person, k of overflow a powerful person is relief valve. When the crock of double lever hydraulic pressure with the valid equal area that is piston both sides when hydraulic pressure crock, but D of take out a powerful person and P of a powerful person. 2. Overflow a powerful person is in the action overflow a powerful person in hydraulic pressure system in hydraulic pressure system is very important, especially system of pump of ration of hydraulic pressure oil pump, work almost impossibly without overflow a powerful person. When does its main function have as follows: 1.

Use at generating back pressure: overflow a powerful person series connection is winding oil path to go up, can generate back pressure, make executive component motion smooth. The setting pressure of overflow a powerful person is right now low, use a powerful person of overflow of the stiff low pressure that use formula commonly can. 2.

Make long-range pressure regulator valve use: Receive the remote control mouth of overflow a powerful person with pipeline to adjust convenient teleregulation entrance is in, in order to come true far dominate an end. 3.

Have effect of stabilized voltage overflow: When offerring oil with mensurable pump, it and throttle cooperate, can adjust and balance the flow in hydraulic pressure system. Below this kind of circumstance, mouth of a powerful person often as the wave motion of pressure open, mouth of a powerful person of oily fluid classics sheds oil sump tank, have effect of stabilized voltage overflow 4.

Make control of tall low-pressure multistage use: Reversal valve joins the remote control mouth of overflow a powerful person and a few long-range pressure regulator valve, can realize tall low-pressure multistage to control. 5.

Have relief valve effect: Avoid hydraulic pressure system and machine tool to cause an accident because of overload. Below this kind of circumstance, valve is closed at ordinary times, only load exceeds open of the ability when formulary limit, have safe effect. Normally, the setting pressure overflow a powerful person is more highest than the system pressure increases 10~20% . 6.

A powerful person of the carry on one's shoulder that make strip uses: Cooperate to use by forerunner overflow a powerful person and a powerful person of magnetism of 2 2 electrify, can make systematic discharge carries on his shoulder or back. 3. With two-way ration the loop of pump inverting uses inverting of two-way and mensurable pump, the positive and negative that wants electromotor of have the aid of to realize pump turns. When turning, oily mouth of hydraulic pump left is mouth giving oil, pressure oil enters left antrum of hydraulic pressure crock via two one-way a powerful person, make fluid accuses F of one-way a powerful person to open at the same time, the E of oily classics throttle of right tune of hydraulic pressure crock and fluid control oil sump tank of F of one-way a powerful person. And the oil absorption of hydraulic pump undertakes through A of one-way a powerful person. This the actuating pressure when right travel of piston of crock of hydraulic pressure of setting of J of overflow a powerful person, loop is symmetrical type oil path, positive and negative spreads a strike to oil similar, no longer give uncecessary details. When using this return circuit, should notice inverting frequency cannot too tall, and should be in carry gently or hydraulic pump starts below condition of discharge carry on one's shoulder.
