Problems solved by technology

Because there are many sundries in the mineral slime, the S pendulum oil cylinder often jams and falls off and leaks oil. After the main oil cylinder is suppressed, the oil pipeline system suppresses the pressure and bursts the fuel injection, which seriously affects the safety of people and equipment. Every time The fuel tank has a large amount of oil replenishment, resulting in a serious waste of hydraulic oil

Embodiment 1

[0061] Such as figure 1 As shown, the present invention provides a coal slime pump oil protection device, including an S swing cylinder position monitoring device 21 and a low oil level protection device 19;

[0062] The coal slime pump includes a hydraulic station and a main pump body;

[0063] The main pump body includes a feed bin 1, an S swing valve mechanism, a first material cylinder 2, a second material cylinder 3, a first master cylinder 4, a second master cylinder 5 and a cleaning chamber 22;

[0064] One end of the first material cylinder 2 is connected to the feed bin 1, and the other end of the first material cylinder 2 is connected to the first master cylinder 4;

[0065] One end of the second material cylinder 3 is connected to the feed bin 1, and the other end of the second material cylinder 3 is connected to the second master cylinder 5;

[0066] The connection between the first material cylinder 2 and the first master cylinder 4 and the connection between th...

Embodiment 2

[0091] Such as Figure 6 As shown, a method for controlling the oil protection device of a coal slime pump. The PLC control module detects the working status of the first S swing cylinder and the second S swing cylinder through the S swing cylinder position monitoring device, and detects the oil level of the main fuel tank through the low oil level protection device. bit;

[0092] When the PLC control module detects that the first S swing cylinder falls off or the second S swing cylinder falls off or the oil level of the main fuel tank is lower than the set threshold, the PLC control module sends a signal to the control switch, and the control switch cuts off the connection between the main power supply and the pump motor connected, the first master cylinder and the second master cylinder stop working;

[0093] When the PLC control module detects that both the first S swing cylinder and the second S swing cylinder are normal, and the oil level of the main fuel tank is greater...

Abstract

The invention provides a coal slime pump oil protecting device and a control method. The device comprises an S-swing cylinder position monitoring device and a low oil level protecting device. A coal slime pump comprises a hydraulic station and a main pump body. The main pump body comprises a feeding cabin, an S-swing valve mechanism, a first material cylinder, a second material cylinder, a first main oil cylinder and a second main oil cylinder. The S-swing valve mechanism comprises an S-swing valve, a first S-swing cylinder and a second S-swing cylinder. The upper part of the S-swing valve isprovided with a first swing arm and a second swing arm. The first swing arm and the second swing arm are V-shaped. The S-swing cylinder position monitoring device is installed on the first swing arm and on the second swing arm. The hydraulic station comprises a main oil tank, a hydraulic pump and a pump motor. The hydraulic pump is connected with the main oil tank, the pump motor, the first main oil cylinder, the second main oil cylinder, a first cylinder and a second cylinder. The pump motor is connected with a control switch. The control switch is connected with a main power source. The lowoil level protecting device is provided and connected with a PLC control module. The PLC control module is further connected with the S-swing cylinder position monitoring device and the control switch.

Description

technical field [0001] The invention belongs to the field of coal slime pump control, and in particular relates to a coal slime pump oil protection device and a control method. Background technique [0002] With the increase of coal output and the development of clean coal technology, the output of coal slime is gradually increasing, which will not only cause serious environmental pollution, but also greatly restrict the development of coal washing slime. The best way to solve the pollution caused by coal slime and deal with a large amount of digested coal slime is direct boiler combustion. The advantage is that the coal slime pump transports the coal slime into the boiler for combustion, which can replace a large amount of raw coal for power generation, further reduce fuel costs, make full use of the advantages of mineral coal slime, improve economic benefits, save energy and reduce emissions, protect the environment, reduce environmental protection, and boiler wear. And f...
