Tube cooler use precautions

Warm tips: Internal media icing will cause damage to the cooler.

1、Please use purified water as cooling medium during operation.

2、Stored or used in ambient temperature below 5 ℃, the water must add antifreeze.

3、Discharge all the internal water when it is out of use or idle to avoid icing and damage to the cooler.

Maintenance of Tube Cooler

●The tube cooler is a device placed in the cooling water circuit and utilizes the temperature of the cooling water to control the temperature of the lubricating oil.

● Its heat transfer tube adopts purple copper tube rolled out with heat dissipation fins, which can make the two liquid mediums with a certain temperature difference realize heat exchange, so as to achieve the purpose of lowering the oil temperature and ensuring the normal operation of the equipment.

● Cooler long-term work, the cooler tube surface will accumulate scale and increase the thermal resistance and flow resistance, so that the heat transfer performance gradually reduced, so as not to ensure that the cooler requirements.

Obviously, the focus of maintenance should be placed on dirt cleaning, here are a few cleaning methods for reference:

Method 1: The use of electric pipe cleaning tools, that is, driven by an electric motor for rotary movement of a flexible shaft, the end of the shaft set of nylon brushes or steel wire brushes for rotary scrubbing, and through a non-leakage of the cover of the water injected into the shaft of the surrounding in order to timely scrubbing the dirt out of the pine.

Method 2: With a round tube, one end of the welded and tube inner diameter similar to the wire brush while rotating while advancing, dirt can be deposited in the inner lumen of the tube, will not produce dirt thicker and thicker to make advancing more difficult, this method is more often used, but labor-intensive.

Method 3: The use of high-pressure pumps (pressure10~20Mpa) spray high-pressure water for flushing, the effect is better, mainly used for cleaning between the tube.

Method 4: The use of sponge ball on the heat exchanger tube for automatic cleaning. According to different layers of scale with different hardness of the sponge ball, for special hard scale, can be used with a “band” of emery sponge ball. Its role is to use the softer and elastic sponge ball into the heat exchanger tube, sponge ball compression and tube walls are in contact with the ball and the tube wall to produce relative motion, constantly friction tube wall, will be removed from the deposits.

Method 5: Often replace the cooling water, because the water use will produce scale, grease scale, rust scale, which is also a reason for the clogging of the copper pipe. Disassemble the front and rear cover, use the air gun to blow every hole in the copper pipe, blow out the scale, and then install the front and rear cover, 0 ring if there is damage replacement.
