Features of mulch film blowing machine:
mulch film series blowing lines are developed by importing Japanese technology and combining with the situation of our country. It is mainly used to produce double colors plastics mulch and agricultural film, such as white and black (or silvery white) film. It resolved successfully many difficult problems for some machines such as easy mix materials, indistinct in color limits, not even in thickness, easy tearing in joint places, etc. It can also be used to produce the double layers film by changing the die partially.
The line has been improved for many times, and it has many merits now, such as the reasonable design, compact structure, convenient operation, especially the main motor has been changed into frequency conversion and after re-equipping the line, the efficiency of the line is increased and the energy consumption is reduced, the whole line function is more advanced and reasonable. And we can also carry full frequency conversion timing and other special equipping according to the consumers requirements.

- Q: How much is the optimum temperature for cooking oil in a centrifugal oil filter?
- Generally speaking, high temperature filtration at 80-85 is appropriate.The amount of water added is about 3.5 times of that in the oil.
- Q: Pneumatic oil filter is slow, isn't it too low?
- Strong magnetic mainly adsorption iron elements, other impurities mainly through the filter block, once the interception of impurities is too much, blocking the filter, on the one hand
- Q: The working principle of centrifugal oil filter
- Through the high-speed rotation of the centrifugal force of the drum and the dregs of oil to leave, liquid-solid separation. When the rotary drum stops rotating, the net oil is slid out of the drum to achieve the purpose of filtration. The oil quality is pure, and the experiment can be done on the fire at the time, fried fritters, stir frying dishes, no foam, no overflow pot. In the past we have used filtration equipment such as: frame filter, vacuum filter, pressure filter is called filter medium (media refers to the cloth, filter, filter cloth mesh) because the medium level of large dregs filtration process is filtered out, small particles through the mesh flow to the oil. This is the past, the filtration effect is relative to solve the quality issues, in operation, the crude oil inside the oil to plug the glial mesh after repeatedly opening the replacement of the filter cloth, cleaning cloth and post consumption.
- Q: Operation of centrifugal oil filter
- 2. separation(1) open the water sealed water valve and seal the water to the outlet of the sewage.(2) slowly change the valve, add the dirty oil to the drum.(3) adjust the oil inlet valve and mediate the proper handling capacity.(4) adjust the pressure of the net oil outlet and enter the normal separation state.
- Q: Is there a national standard for oil filters?
- The machine is composed of filter bed, oil pump and rough filter. With industrial filter paper as filter medium, different filter paper can be selected according to different filter requirements, and the filtering accuracy is high. The utility model has the advantages of simple structure, easy operation, low operation cost, etc..
- Q: What is the reason for the foam in the EH tank when the oil filter in the turbine EH oil filter?
- [5]: the design of flash vacuum oil filter has a problem, no matter what type of vacuum oil filter machine, its basic principle is in high vacuum environment, according to the different oil flash point, heating evaporation and separation. If the vacuum system design is unreasonable, low vacuum or gas channel are short, will lead to dehydration and incomplete packing layer of water, gas evolution, will fall into the formation of foam oil after filtration, with the final system into the tank. In particular, many of our peers vacuum flash tower using inferior packing or bulk packing, easy to cause the oil retention and partial wall flow (tube wall residual vacuum flash tower), finally fell into the oil bubble.[6]: vacuum vacuum oil filter in operation is too high, resulting in high temperature makes the transition flash, light hydrocarbons, oil additives into the analysis of mixed with oil bubbles, and high degree of vacuum in a large amount of water vapor if it is not timely recovery, or design recovery ability is not good, will cause water vapor and oil interact to form a new bubble.
- Q: Why is the gas filter not clean?
- Air pressure filter has been too accurate, not used
- Q: Is the pressure type oil filter better than the vacuum oil filter?
- Pressure type is a relatively simple filter, the principle of a single filter
- Q: How to solve the problem of oil leakage in the centrifugal oil filter?
- Causes of oil leakage:Filter 1. centrifugal oil filter in the case not properly installed, cause when the machine is running into oil in crude oil2. there are many impurities in oil, and the oil outlet is blocked
- Q: The same function, one is installed in a part of a system, and the oil filter can move, do not need other devices can be completed independently
- 2, the dehydration efficiency is the fastest coalescence oil filter, followed by centrifugal, finally vacuum oil filter; dehydration effect is the best, ZYAXD double stage vacuum oil filter, taking into account the dewatering efficiency and dewatering effect is the coalescence of vacuum oil filter, the dehydration effect is the worst centrifugal filter oil machine. The highest price is the coalescing vacuum oil filter, followed by the vacuum oil filter, and finally the centrifugal oil filter.
