QI Series Ball Joint

QI Series Ball Joint
ISUTAMI ball joint is installed between the ball head and the connecting rod body to realize the mechanical connection between the ball head and the connecting rod body and the transmission of power. The driving force of the ball head part can drive the connecting rod part to move through the ball head connecting rod.An important part of the connector is the pull rod of the ball head housing and the ball head of the steering shaft in the housing. The ball head is hinged with the edge of the axle hole of the ball head housing through the ball head seat at the front of the housing. The ball head seat and the steering spindle are embedded in the hole surface groove of the ball head housing, which can reduce the wear of the ball head and improve the tensile strength of the spindle.

QI Series Ball Joint Features

The ball joint shall be provided with self-control at the appropriate position of the supply road and additional bending at the appropriate position of the return pipe according to the characteristics of the force bearing.When the system is running, the pressure difference before and after the force difference can be kept basically constant, so that the moving line at the back of the network is relatively low, which can meet the requirement of the disperser not being crushed.The dynamic pressure line at the front of the spherical joint is relatively high, which can meet the requirement of no emptying.When the system stops running, the pressure control automatically closes, along with the return line, separating the rear from the front.The static line in the front is guaranteed by the voltage compensation device, while the static line in the back of the network is guaranteed by the compensation adjustment on the compensation force connecting the front and rear.If the pressure difference before and after is less than the setting difference when the formula itself is in the closed state, it will continue to close.If the pressure difference before and after the valve is greater than the set difference, open.When it is in the open state, the opening degree can be automatically adjusted to make the front and rear basic constant.Compared with the traditional control protection, the force type has the advantages of reliable control and low price.Self-reliance can be used to solve the contradiction of different working condition requirements caused by the great difference in concentration.
