How to select Rexroth solenoid valves

1. Characteristics of the medium 1) Different varieties of solenoid valves are selected for gas, liquid or mixed state; 2) The medium temperature is different for products of different specifications, otherwise the coil will burn off, the seal will age, and the life of the product will be seriously affected; 3) The viscosity of the medium, usually below 50cSt. If...

Technical Parameters: 1) Select the valve port and model according to the requirements of the medium flow direction and the pipeline connection mode; 2) According to the flow rate and valve Kv value to select the nominal diameter, can also choose the same pipe inner diameter; 3) Working Differential Pressure: Low working differential pressure above 0.04Mpa is optional.

1. Check the internal leakage of the boom cylinder. The easiest way to do this is to raise the boom and see if it has a noticeable free descent. If the drop is obvious, disassemble the cylinder for inspection, and replace the sealing ring if it is worn; 2. Check the control valve. First of all, clean the safety valve and check whether the valve core is grinding.

The first step is the debugging of the zero position in the no-load state Most of the servo valves on construction machinery are used in conjunction with the reversing valve to achieve the purpose of controlling the hydraulic system. The servo valve plug-in can be unplugged on the site to prevent the servo valve from being energized and make it in a no-load state. Then, a manual or electric directional valve, ...

First, the rigidity of the hydraulic oil decreases sharply, resulting in the slower response of the hydraulic system and the reduction of efficiency, resulting in crawling and vibration of the actuator. Second, air bubbles will cause oil film to be unable to form between moving parts, resulting in poor lubrication and aggravating the wear of hydraulic components. The third is in the air ...

· Integrate know-how from all parties through an ecosystem · Low-code/no-code: Five times faster time to market · Independence from global supply chains · Long-term availability The industrial automation transformation is well underway and will take a big step forward in 2022.

In 2020, Bosch Rexroth took a big step forward on the road to automation openness with the ctrlX AUTOMATION automation automation platform based on the "Industrial Automation Smartphone" concept. In 2021, Bosch Rexroth made the leap from an open platform to an industrial ecosystem. Co-creation ...

Debugging considerations exhaust All PV7 vane pumps are self-priming. Prior to commissioning, the pump must be emptied to prevent damage to the internal components. When commissioning, it is advisable to fill the housing through a leak port. Pay attention to the filter accuracy class! This will improve the operation ...

1. First of all, adjust the pressure adjustment screw of the Rexroth variable hydraulic pump relief valve to the loosest state, the minimum flow limiter to the minimum state (the upper hydraulic cylinder adjusting screw is adjusted to the loosest state), the flow control valve adjustment screw is adjusted to the tightest state, and connect a flow rate in series after the flow valve.

Technical parameters 1) Select the valve port and model according to the requirements of the medium flow direction and the pipeline connection mode; 2) According to the flow rate and valve Kv value to select the nominal diameter, can also choose the same pipe inner diameter; 3) Working pressure difference: The minimum working pressure difference is above 0.04Mpa.

Rexroth hydraulic pumps have a wide variety of applications and are available in all walks of life. In terms of pump performance, there are two types of pumps: giant pumps and micro pumps. Giant pumps can reach flow rates of hundreds of thousands of cubic meters per hour, while micro pumps can reach less than tens of milliliters per hour. Judging by the pressure of the pump, it can be ...

The flow rate of Rexroth Rexroth oil pump is the product of the gear pump displacement V per revolution and the speed n, if the speed n of the hydraulic pump is too low, the initial force Q will be too small, can not guarantee the oil supply of the system, resulting in the centripetal force is not enough or can not constitute a certain vacuum degree and can not absorb oil. ...

1. Daily maintenance 1) Strictly implement the post operation method and carefully fill in the operation records. 2) Check the bearing temperature and oil pressure regularly; Check the level height of the lubricating oil every shift. 3) Check whether there is leakage in the sealing part once per shift. 4) Do a good job in each shift ...

1. Workload cycle 2. Oil type 3. Minimum flow rate and maximum flow 4. Pressure range 5. System type: open system or closed system 6. Ambient temperature, system working temperature and cooling system 7. Oil pump type: gear pump, ...

1. Rexroth hydraulic pump has no flow rate. In fact, this is broadly similar to the reason why Rexroth hydraulic pumps have no pressure as mentioned earlier. Here can be referred to by the explanation of the past period, and a few points can be added. 1. Installed on Rexroth hydraulic pump ...

1. Causes of noise and vibration failure of relief valves The components that are prone to noise in hydraulic devices are generally considered to be pumps and valves, and the valves are mainly relief valves and electromagnetic reversing valves. There are many factors that contribute to noise. There are two types of noise in the relief valve: velocity sound and mechanical sound. The main ...

How can you transform a high-speed milling machine for dental products into a high-performance automatic machining system for the automotive industry? The Göttingen-based mechanical engineering company Akcurate & CIMT took up the challenge and solved it with a complete solution from Bosch Rexroth. 　　Dental implant ...

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.

1. The speed and pressure of the pump should not exceed the specified value, and long-term use should be avoided, otherwise the life of the hydraulic pump will be affected. 2. When the hydraulic pump is started, it should be jogged several times, and after the oil flow direction and sound are normal, it should run under low pressure for 5-10min, and then put into normal operation. ...

1) If the cylinder body is inlaid with copper sleeve, it can be repaired by replacing the copper sleeve. First of all, trim the diameter of a set of plunger rods to a uniform size, and then polish the outer diameter with sandpaper of more than 1000#. There are three ways to install copper sleeves in the cylinder block: (a) Heating and hot charging of the cylinder block or low-temperature freezing and extrusion of the copper sleeve, interference ...
