Q: your screw pressure chance will not be blocked? What to do if it is blocked? How to reverse? What is the principle? Does it affect the machine?

A: our company selects and purchases raw materials from manufacturers with good flatness of cold-rolled plate. Each ring piece must go through two procedures, mechanical and manual, which can greatly reduce the blockage of screw press. Compared with centrifuge and belt machine, screw press is not easy to block. However, due to various reasons such as uneven materials and operation, sometimes it is inevitable to jam. Generally, it can be handled by reversing the machine after blocking. Please start the reversing button for reversing.

Q: when you rotate at 2-3 revolutions / s, if the number of revolutions reaches 4 or 5, is the processing capacity doubled?

A: the processing capacity can not be determined by a single speed, but also by a series of parameters such as the type of material to be separated, viscosity, temperature, number of laminations, size, gap, length of spiral shaft, back pressure, etc. Some manufacturers often increase the speed to improve the processing capacity. In a short time, there may be no problem. In a long time (3-6 months later), it is easy to cause machine wear and so on.

Q: is it better to use metering pump or screw pump?

The metering pump is suitable for the occasion with less dosage, its advantage is accurate, but its relative price is higher. Screw pump dosing is suitable for the occasion of large dosage, with flowmeter and frequency converter (or manual reflux) can also achieve accurate dosing.

Q: can screw presses be placed outdoors?
