Description
Technical Field
The utility model relates to a mechanical seal outer circulation cooling system heat exchanger.
Background
The mechanical seal external circulation cooling auxiliary system is a guarantee mechanism for guaranteeing stable operation of mechanical seal, and comprises a liquid storage tank, a pressure boosting tank, a pressure alarm device, a voltage stabilizer, a liquid supplementing pump, a heat exchanger and other parts, and has different requirements and different configuration schemes.
In the heat exchanger of the mechanical sealing external circulation cooling system in the prior art, a cooling water inlet pipe orifice and a cooling water outlet pipe orifice are arranged on a heat exchanger tank body, and a sealing and isolating liquid-oil cooling coil and a baffling sleeve are arranged in the heat exchanger tank body. The sealing isolation liquid oil is cooled in the heat exchanger tank body through heat exchange of the cooling coil and then sent back to the mechanical seal cavity to cool the mechanical seal cavity and the mechanical seal.
Whether the mechanical seal can stably operate or not is greatly related to the cooling effect and the pressure of the sealing and isolating liquid oil.
In the course of the work, impurity, the sealed powder of wearing and tearing that produce in the sealed liquid oil circulation pipeline of keeping apart all can remain in sealed liquid oil circulation pipeline of keeping apart, enter into mechanical seal intracavity at the inferior circulation, can lead to sealed terminal surface accumulation impurity particulate matter like this for a long time, lead to mechanical seal accelerated wear to become invalid.
In order to achieve the length of the heat exchange area of the sealed and isolated liquid oil cooling coil, a plurality of pipes are often welded, the sealed and isolated liquid oil cooling coil leaks due to various reasons, the pressure of a mechanical seal cavity for sealing and isolating liquid oil is insufficient, and the mechanical seal cavity is difficult to judge whether the mechanical seal mechanism is damaged or the sealed and isolated liquid oil cooling coil leaks, the pressure of the mechanical seal cavity is reduced, the mechanical seal is caused to lose efficacy by accelerated wear, toxic, harmful, flammable and explosive media leak, and even disastrous accidents are caused.
In addition, the heat exchanger is used for reducing the cooling equipment of packing isolation liquid oil temperature, cools through cooling water, guarantees that packing isolation liquid oil is in design temperature range. However, as the cooling water quality is poor, when a large amount of impurities exist, scales are accumulated on the sealed and isolated liquid oil cooling coil in the heat exchanger, the heat exchange cooling effect is reduced, the temperature of the sealed and isolated liquid oil is increased, and the safe and stable operation of mechanical sealing is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a mechanical seal outer circulation cooling system heat exchanger to overcome above-mentioned prior art not enough.
The utility model discloses mechanical seal extrinsic cycle cooling system heat exchanger has seted up the cooling water feed liquor mouth of pipe, cooling water play liquid mouth of pipe, is equipped with sealed isolation liquid oil cooling coil and baffling cover, characterized by in the heat exchanger jar body on the heat exchanger jar body:
the upper end part in the heat exchanger tank body is provided with a resistance sensing probe, a liquid outlet filter is connected and arranged on a liquid outlet pipe orifice of the sealed isolating liquid-oil cooling coil, and a cooling water inlet filter is connected and arranged on a cooling water inlet pipe orifice of the heat exchanger tank body.
The utility model is provided with a resistance induction probe on the upper part of the heat exchanger tank body, when the sealing and isolating liquid oil cooling coil pipe leaks, the isolating liquid oil leaking from the sealing and isolating liquid oil cooling coil pipe floats on the upper part of the liquid storage tank because the specific gravity of the oil is greater than that of the cooling water in the heat exchanger tank body; the conductivity of oil is close to zero, while the conductivity of water is good; after the resistance sensing probe is contacted with the isolation liquid oil, the resistance is changed from small to large, and display alarm and timely discovery processing are carried out.
The liquid outlet filter is connected and arranged on the liquid outlet pipe opening of the sealed and isolated liquid oil cooling coil, so that impurities generated in the sealed and isolated liquid oil circulating pipeline are effectively prevented from being returned into the mechanical sealing cavity, and the service life of the mechanical seal is prolonged.
Connect on heat exchanger tank body cooling water feed liquor mouth of pipe and be equipped with cooling water filter of intaking, prevent that impurity in the cooling water from leading to piling up the scale deposit on the sealed spacer fluid oil cooling coil in the heat exchanger, reduce heat transfer cooling effect.
The utility model has simple structure and convenient manufacture and use.
