There are three main types of hydraulic pumps: gear pumps, vane pumps and piston pumps. 1. Gear pump: Advantages: small size, simple structure, less strict requirements for the cleanliness of the oil, and cheaper price; Defects: However, the pump shaft is subject to unbalanced force, serious wear, and leakage.

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.

1. Remove the mold and cancel the express and trivial mold operation 2. Cancel the low-pressure trivia mold. 3. Close the safety door. 4. Adjust the CNC high-speed mold speed to the value of 0, and adjust the CNC high-speed mold opening speed and CNC low-speed mold opening speed to the value of 40. 5. Starter oil ...

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) ...

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

Rexroth hydraulic pump is the power component of the hydraulic system, it refers to the oil pump in the hydraulic system, it is the hydraulic component that provides liquid for hydraulic transmission, and it is also a kind of pump. Its function is to convert the mechanical energy of the prime mover into the pressure energy of the liquid, that is, the hydraulic system is ...

1. The power domain (working limit) of the proportional valve For direct-acting electro-hydraulic proportional throttle valves, since the hydraulic force acting on the valve core is proportional to the flow rate and flow rate (pressure) through the valve port, when the working condition of the electro-hydraulic proportional throttle valve exceeds the product of its pressure drop and flow rate, that is, the power meter...

1. Preparation before starting: check the fastening of each component; Check the oil level of the oil tank, the height of the oil level is subject to the engraving line of the oil window on the oil tank, N46 in summer, N32 hydraulic oil in winter. High-pressure pumps and pumps above 140 should use the same type of anti-wear hydraulic oil. Check the pressure gauge range, liquid ...

1. The pump does not absorb oil, the flow rate is not enough, the pump is empty, and the pump is damaged. Damaged pumps, damaged skates or damaged ski and column ball joint seals; swash plate wear; wear of plungers and cylinder bores; failure of variable mechanisms; Wear of the oil distribution pan or wear of the oil distribution end face of the cylinder block; The LS valve of the pump is worn, the pressure is cut off...

Space-saving design: The measuring sensor is fully integrated into the slide Cost-effective position measurement system for a wide range of product sizes From design to service, save time and money 　　Integrated absolute position measurement is used in a wide range of applications, due to its high water ...

1. Pressure reducing and stabilizing valve Main features: 1. Piston type with DN65 caliber or above. The life of the diaphragm is increased by more than 3 times; 2. Below DN50 caliber, the original diaphragm is replaced by a flat diaphragm of nylon reinforced rubber, which also improves the service life by more than 3 times. Applicable medium: water, air. Medium temperature ...

When Rexroth hydraulic pump motor has air, how do we correctly eliminate it so that the pump is not damaged, and then share with you the correct exhaust method: (1) The oil has a certain compressibility, resulting in noise, vibration and crawling of moving parts in the system.

1. Cause of failure: the oil level of the hydraulic oil tank is too low; Exclusion method: Add hydraulic oil. 2. Cause of failure: Hydraulic oil is not used according to the season; Exclusion method: Usually suitable for 46# hydraulic oil (or 68#) without special replacement, consider using it when it is cold in the north in winter...

1. First, adjust the pressure adjusting screw of the relief valve to the loosest state, adjust the minimum flow limiter to the minimum state (the adjusting screw of the hydraulic cylinder in the upper part is adjusted to the loosest state), adjust the adjusting screw of the flow control valve to the tightest state, and connect a flowmeter in series after the relief valve; 2. Start-up fluid ...

Power condition 1) According to the type of power supply, AC and DC solenoid valves are selected respectively. In general, AC power is easily accessible; 2) AC220V.DC24V is preferred for voltage specifications; 3) The power supply voltage fluctuation is usually +%10%.-15% AC, and the power supply voltage fluctuation is usually +%10%.-15%.

Causes of failure: (1) The oil level of the hydraulic oil tank is too low; Exclusion method: Add hydraulic oil Causes of failure: (2) Hydraulic oil is not used according to the season; Exclusion method: Usually suitable for 46# hydraulic oil (or 68#) without special replacement, consider using 32 ...

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) Rexroth vane pumps: Some users do not fill the pump with enough water before starting; It appears that the water has spilled out of the vent, but the air is completely discharged without turning the pump shaft, so that a little air remains in the inlet pipe or pump body. 2) Rexroth vane pump contact inlet pipe horizontal section of the counter-water flow ...
