For example, it was the first injection molding machine to open ...

1) Coil problem Use a voltmeter to measure the voltage across the coil. This should help you determine if the coil is working properly. You can also gently pull the coil to feel if there is a magnetic force acting on it. If it proves difficult to pull, the coil generates a magnetic field, which creates an excitation.

The replacement specification of oil lift piston pump parts, when the various clearances listed are out of tolerance, can be corrected as follows: 1) If the cylinder body is inlaid with copper sleeve, it can be corrected by replacing the copper sleeve. First trim a set of plunger rods to a consistent size, and then polish the outer part with sandpaper of more than 1000#.

1. The flow direction of the medium should be consistent with the direction of the arrow of the valve body; 2. The differential pressure balance valve should be installed on the return pipe, the valve is connected to the guide pipe, and the other end of the pressure guide pipe is connected with the water supply pipe, and it is recommended to install a 1/2" ball valve at the water supply end of the pressure guide pipe in order to start the function of eliminating blockage; 3、 ...

1. Conduct regular testing and diagnosis of Rexroth piston pumps According to the listening and collecting signals, the western line diagram of the online working performance of the Tule Pillar Jiquan was made, and the evaluation report was made. Based on the results of home monitoring, it is decided whether to repair the Rexroth plunger atmosphere. In this way, the optimal dimension of the Piston Pump ...

Efficient hydrogen compression can halve the total cost of ownership for operators More economical delivery helps to reduce the price of hydrogen refueling Automatic seal replacement for easier maintenance 　　The container-based hydrogen compressor MAX Compression 2.0 is equipped with a digital hydraulic system from Bosch Rexroth ...

1. Constant pressure overflow: In the throttling adjustment system of the quantitative pump, the fixed pump provides a constant flow rate. 2. When the system pressure increases, the flow demand decreases. 3. At this time, the safety valve is opened, so that the excess flow is returned to the oil tank to ensure the inlet pressure of the safety valve.

An automation platform with an ecosystem can perform a wide range of tasks Provide low-code engineering and applications for bot applications Web-based HMIs and consumer device applications are possible One device for multiple tasks: security, data analysis ...

1. The filter on the suction pipeline is blocked; 2. The oil level of the hydraulic oil tank is too low; 3. The R angle of the variable mechanism is too small, so that the flow rate is too small, and the influence of internal leakage is added, so it cannot continuously supply pressure oil to the outside world; 4. The strain between the oil distribution pan and the contact surface of the cylinder block is serious, and it is not sealed or ...

1) The maximum and minimum temperature of the environment should be selected within the allowable range; 2) When the relative humidity in the environment is high and there are water droplets and rain, waterproof solenoid valves should be selected; 3) Special varieties should be selected for occasions such as vibration, bumps and shocks in the environment, such as marine solenoid valves; ...

1) Electrical proportional mode, to achieve stepless control of outlet pressure. 2) It can realize remote control and program control. 3) Compared with intermittent control, the system is simplified and the components are greatly reduced. 4) Compared with hydraulic proportional valves, it is small in size, light in weight, compact in structure, and lightweight.

1. The principle of Rexroth hydraulic pump oil volume adjustment Generally, in order to adapt to the specific requirements of the diesel engine under the load, the fuel injection pump must be able to adjust the maximum fuel supply to the zero oil supply range of the whole machine when the fuel supply is running.

Simplify the design The complete solution can be customized according to the user's needs Digital on-board electronics Compact design (integrated pressure sensor technology) External pressure sensor connection to meet the user's customized application needs The interface can be customized on demand ...

1) Cannot be opened or closed normally 1. Check the power supply and make sure the voltage and frequency are correct. Also check the connection. 2. Check whether there is dirt, corrosion underneath, and the coil will not burn out or lose components. 3. Check whether the flow direction is related to the indicator on the valve body or with the valve ...

The hydraulic motor is fixedly connected to the housing, and the oil propulsion rotor entering from the port rotates around a central point. This slow-rotating rotor drives the output through a splined shaft called a cycloidal hydraulic motor. After the advent of this early cycloid motor, through decades of evolution, another concept of horse ...

1. Direct-acting solenoid valve Principle: When the normally closed type is energized, the electromagnetic coil generates electromagnetic force to lift the open part from the valve seat and open the valve; When the power is off, the electromagnetic force disappears, the spring presses the opening on the valve seat, and the valve is open. Features: In vacuum, negative pressure, zero pressure ...

Rexroth hydraulic pump is mainly divided into three types: piston pump, gear pump and vane pump, among which Rexroth vane pump is a special clamp clamping pump body and pump cover, and the outlet direction of the pump can be in any direction of 360 degrees, which is easy to install and use. The bearing assembly of the sand pump is made of cylindrical structure, ...

Adjust the pressure adjustment screw of the relief valve to the loosest state. The variable displacement piston pump is an A10VSO constant pressure variable displacement pump with flow limiter. Rexroth A10VSO variable pump is actually based on the constant pressure variable pump with a flow limiter (represented by the suffix S0169) ...
