The mixer is composed of a chassis and a top mount. The top mount is important except that the mixing tank is the hydraulic system, and the hydraulic oil pump in the hydraulic system is a relatively fine component, so pay great attention to the use and maintenance of the hydraulic oil pump during the operation of the mixer.
Working principle of oil pump: when the variable lever is rotated to the left through the joystick device, the oil pump starts to drain oil from the oil port, enters the motor through the high-pressure oil pipe, the motor rotates, the oil flowing through the motor becomes low-pressure oil, and then flows back to the oil pump through another high-pressure oil pipe from another oil port. The larger the rotation angle of the variable lever, the more oil will be discharged by the oil pump per revolution, and the higher the speed of the motor. When the variable lever is operated to rotate to the right, the pressure oil is discharged from the other port, the rotation direction of the motor changes, and the low-pressure oil flows back to the oil pump from the oil port.
The rotation of the motor drives the reducer, so that the mixing tank of the mixer can be infinitely variable within a certain speed range and has two rotation directions. The principle of other hydraulic oil pumps is the same. To make the hydraulic oil pump work efficiently and trouble free, it is necessary to strengthen the maintenance in daily use, operate according to the instructions, and replace the hydraulic oil and auxiliary devices in time as required.
Pay attention to the following points when changing hydraulic oil:
1. Use hydraulic oil with stable performance that meets the requirements, and do not use filtered and precipitated hydraulic oil.
2. The oil filter is easy to use, and the filtering accuracy is 10.
3. The shells of the main system, pump and motor should be filled with hydraulic oil before starting.
4. The hydraulic oil and filter element should be replaced in time according to the instructions.
The hydraulic system of mixer includes domestic, Sino foreign joint venture and imported ones. Generally, the standard configuration of small mixer is domestic hydraulic system, and the standard configuration of large mixer is imported or Sino foreign joint venture hydraulic system. Of course, in addition to the standard configuration, it can also be optional, which can be installed according to the needs of customers. The price of hydraulic system of different brands is also different. Come to the website for more relevant information http://www.zkhntjbj.com Follow to get.
