Hydraulic roof support is the key equipment in the longwall mining method,which are used to support the tunnel roof of the mining face to make a space for armored face conveyors and shearers to operate underneath.The development of filling hydraulic support can prevent the ground subsidence, to fully realize the coal mining under buildings, railways and waterbodies, to prolong the service life and save resource.
Meaning of model
- Q: The equipment of our unit needs to be cleaned regularly, oil pollution is very much, every time manual washing efficiency is too low, what method can be solved quickly?
- First, the source and composition of the oil pollution should be made clear. In particular, it is clear that it is possible to take medicine against the disease. The oil on general equipment is divided into two categories: lipids and oils. The best way to deal with lipids is by physically removing and chemical decomposition. In the case of oils, the main thing is chemical decomposition. Because you do not know the type and structure of your device, you can only suggest the following: 1, before manual cleaning, the specific chemical decomposition should be arranged so that the cleaning can be twice as effective. According to the source of the oil pollution, do the precautionary setting. For example, it is easier to paste the protective coating on the spot where the oil pollution is frequently occurring. Use special tools and equipment to clean up the oil. Personal sense, the process of decomposition is important. For your reference.

- Q: Clean the cleaning parameters of the equipment
- Judge a ultrasonic cleaning machine general technical indicators as to stay ageing degree and resonant, impedance and impedance matching are already debugged before they go out, the key lies in you to do. Of course, the sound of ultrasonic cleaning machine and generator is now being silenced. The bonding mode of the oscillator is usually made of special cement, and the bolt fastening effect is good, but it is not suitable for maintenance. Frequency selection is cleaned according to the workpiece to decide, general material or on the surface is not very high, with 28 KHZ, more strict for cleaning, or had better choose high precision parts. This is because, the lower the frequency of the bubbles, the greater the when ultrasonic frequency is greater than 800 KHZ, there is no cavitation bubbles, this to be the effect of cleaning the surface of the cavitation corrosion is the lowest. In addition, the ultrasonic cleaning is the effect of the high pressure produced by an empty bubble in the instantaneous blast.
