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. Frequent grease, the electric oil drum pump is running at high speed, and the grease is easy to volatilize, so it is necessary to keep the lubrication at the bearing clean and pay attention to the replacement. 2. Pay attention to the storage of the electric pumping pump should be placed in a dry, clean and no corrosive gas environment. 3. Gear oil ...

1. In the mining and metallurgical industry, the pump is also the most used equipment. Mines need to be drained by pumps, and in the process of beneficiation, smelting and rolling, pumps are needed to supply water first. 2. In the power sector, nuclear power plants need nuclear main pumps, secondary pumps, tertiary pumps, thermal power plants need a large number of boilers ...

Piston pumps are generally divided into single piston pumps, horizontal piston pumps, axial piston pumps and radial piston pumps. Single piston pump The structure consists of an eccentric wheel, a plunger, a spring, a cylinder block, and two check valves. A closed volume is formed between the plunger and the cylinder bore. The eccentric wheel rotates and the column ...

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 ...

With the continuous progress of technology and the needs of market applications, the emergence of proportional valve is a more intelligent valve, which provides convenience for technicians, but also reduces the tedious work tasks, the most important structural unit of proportional valve is the proportional signal control system, which is based on the specific ring ...

Bosch Rexroth, a leading global supplier of drive and control technology, is building a new plant in Querétaro, Mexico, and will further strengthen its presence in North America. Bosch Rexroth has been successfully operating in Mexico for 40 years. From the summer of 2023, the walking machines of Querétaro ...

Rexroth piston pump failure manifests itself as follows. The causes and elimination methods of excessive working noise of piston pumps. There is air in the oil pump. This failure usually occurs when a new pump is installed. When opening a new pump, oil should be added to the pump first to lubricate the pump's bearings, plungers, and cylinders. ...

A Rexroth hydraulic motor is an actuator of a hydraulic system that converts the liquid pressure energy provided by a hydraulic pump into the mechanical energy (torque and speed) of its output shaft. Hydraulic motors, also known as oil motors, are mainly used in injection molding machinery, ships, hoists, construction machinery, construction machinery, etc.

Single piston pump It is mainly composed of an eccentric wheel, a plunger, a spring, a cylinder block and two check valves. A closed volume is formed between the plunger and the cylinder bore. Slanting...

The classification of proportional valve control mode refers to the classification of the electrical-mechanical conversion mode in the pilot control valve of the proportional valve, and its electrical control part has various forms such as proportional solenoids, torque motors, DC servo motors, etc. (1) Electromagnetic type Electromagnetic type refers to the use of proportional electromagnets.

1. It is necessary to avoid the retention of dirt and debris into the pressure reducing valve pressure reduction guarantee system. The pipe network of the pressure reduction system of the new or renovated project is likely to leave sand, hemp silk and debris. Before putting into operation, water flushing should generally be carried out, and after meeting the cleaning requirements, the pressure reducing valve and filter element should be finally installed.

1. 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. Before the piston pump is started, the pump must be filled with clean working oil through the oil drain port on the casing. 2. The viscosity of the oil is affected by the temperature ...

Classification and structural characteristics of Rexroth gear pumps 　　According to the form of gear meshing, it can be divided into external meshing and internal meshing.
