How can we use the regulator correctly?

The regulator compares the measured value of the parameters of the production process with the given value, and after the deviation is obtained, an output signal is generated according to a certain adjustment rule to push the actuator to eliminate the deviation, so that the parameter is kept near the given value or changes according to a predetermined rule. controller.

What's the matter with the hydraulic pump regulator not being able to regulate?

1. Long-term failure to change the oil and long-term disrepair will cause serious oil pollution, causing the valve to be stuck in the normally open position (and some unauthorized removal of the valve), so the oil return controller does not have a heat dissipation effect, which is bound to cause the oil temperature to be too high.

2. Caused by poor heat dissipation performance of the controller, such as deformation or blockage of the external heat dissipation fins, poor cooling effect; insufficient cooling fan capacity; blockage of the internal pipes of the hydraulic oil controller.

3. It is found that the oil level in the shock absorber box is much higher than the oil level screw (generally about 1.5L), and this excess oil generates a lot of heat and transmits it to the hydraulic pressure during the rotation of the shock absorber. pump, causing the system to heat up.

Hydraulic pump regulator maintenance should consider the type of hydraulic pump, hydraulic lift and hydraulic lift platform hydraulic system working pressure.

How to adjust the parameters of the hydraulic pump regulator?

The hydraulic pump regulator needs to be adjusted clockwise to increase the power and counterclockwise to decrease. The formula: power is equal to the pressure multiplied by the flow rate. Under the condition that the engine speed is constant and the pressure is constant, the greater the power, the higher the output flow rate of the pump. more. It should be noted that the two pumps should be adjusted together, with 90° as the adjustment value.

How to use and maintain the regulator?

1. Remove the protective cover and check whether there is any dirt and burns on the contact surface of the regulator. If there is dirt, wipe the contact surface with a relatively clean paper. If the contact is ablated or the plane is uneven, resulting in poor contact, generally use "00" sandpaper or sand strip to smooth it, and finally wipe it with clean paper.

2. Check the firmness of each connector of the regulator, and measure the resistance and the resistance value of each coil. If it is damaged, it should be repaired or replaced in time.

3. Check the closing voltage and reverse current of the circuit breaker, the limit voltage of the voltage regulator, the limit current of the restrictor, and the gaps and air gaps of various contacts. If the regulator does not meet the requirements, it should be adjusted.
