自动上料搅拌机是由底盘和上装组成的，其中上装重要的除了搅拌罐就是液压系统了，而液压系统中液压油泵是比较精细的部件，所以在搅拌机的操作过程中要非常注意液压油泵的使用和维护。

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.

油泵的工作原理：当通过操纵杆装置使变量杆向左转动，油泵就开始从油口排油，经过高压油管进入马达，马达转动，流经马达的油变成低压油，再经过另一高压油管从另一个油口流回油泵。变量杆转动角度越大，油泵每转排出的油量就会越多，马达的转速就越高。当操纵变量杆使其向右转动，这时压力油就从另一口排出，马达旋向改变，低压油从油口流回油泵。

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.

马达的转动带动了减速机，从而使搅拌机的搅拌罐能在一定转速范围内无极变速且有两种旋向。其它液压油泵原理也是如此。要使液压油泵、无故障的工作，就要在日常使用中加强维护保养，并按说明书进行操作，按要求及时的对液压油和辅助装置进行更换。

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.

液压油更换需要注意一下几点：

Pay attention to the following points when changing hydraulic oil:

1. 使用性能稳定符合要求的液压油，好不要使用经过过滤和沉淀的液压油。

1. Use hydraulic oil with stable performance that meets the requirements, and do not use filtered and precipitated hydraulic oil.

2. 滤油器好使用过滤精度为10的。

2. The oil filter is easy to use, and the filtering accuracy is 10.

3. 主系统、泵、马达的壳体在启动之前要充满液压油。

3. The shells of the main system, pump and motor should be filled with hydraulic oil before starting.

4. 液压油和滤芯要按说明书及时更换。

4. The hydraulic oil and filter element should be replaced in time according to the instructions.

搅拌机的液压系统有国产的、中外合资的、进口的，一般小型的搅拌机标配的都是国产液压系统，大型搅拌机一般标配的都是进口或中外合资的液压系统，当然除了标配，也可选装，可根据客户的需求来安装，不同企业的液压系统价格也是不同的。更多相关信息就来网站http://www.zkhntjbj.com关注获取到。

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.
