Description

The condensing pressure watch-dog

The utility model belongs to the device of monitoring condensing pressure in refrigeration system.

On the refrigeration system of large cold storage, condensing pressure value is important data.The rising of condensing pressure will cause that unit cold wasted work increases, and according to measuring and calculating, condensation temperature is between 25 ℃, and 1 ℃ of every rising increases power consumption about 3.2%, and condensation temperature raises 1 ℃, and corresponding condensing pressure raises 0.3 * 10 approximately ⁵Pa (0.03MPa) is difficult for finding for the duty management personnel.On the one hand, its scale division value of high-pressure manometer that present refrigeration system is adopted is 0.05MPa, and pressure variation indication on Pressure gauge of 0.03MPa is not obvious; On the other hand, the operator on duty is in the process of patrolling and examining, and the sensation of can't renting is confirmed cooling water temperature exactly or is difficult for determining that according to cooling water temperature rational condensing pressure and actual condensing pressure compare and take measures at any time.

The purpose of this utility model is in order to solve the problem of above-mentioned existence, a kind of condensing pressure watch-dog to be provided.When condensing pressure surpasses setting, can send the instruction works signal, the normal factor that causes that condensing pressure raises is got rid of or sent sound and light alarm, remind the operator on duty to take measures, owing to having got rid of the reason that raises and cause cooling pressure to raise because of the cooling water water temperature, making the operator on duty analyze pressure rising reason more has certain accuracy and specific aim, instructs it to take correct measure.

In order to achieve the above object, of the present utility modelly be characterised in that both sides are equipped with condensing pressure receptor and coolant temperature receptor respectively in housing, the formation of a, condensing pressure receptor is: have the tank body that a left side is taken over, tank inner chamber is that left bellows is housed, a left side connects a left push rod on the bellows bottom surface, between left push rod and housing, counterbalance spring is housed, push rod top, a left side connects a stepped left contact arm, temperature difference adjustment disk is equipped with in contact arm terminal bottom in a left side, on this temperature difference adjustment disk spring and touch points is housed; The formation of b, coolant temperature receptor is: the tank body of dress R22 working medium in, this tank body is communicated with a pressure transmission capillary, at the pressure transmission capillary end is the temperature-sensitive bag, right bellows is housed in tank inner chamber, on right bellows inner bottom surface, connect a right push rod, be provided with the right push rod of the too high and normal contact of condensing pressure top on right push rod right contact arm is housed, right contact arm is provided with the spring sensing mechanism, and this spring sensing mechanism is in temperature difference adjustment disk top; C, on housing, be provided with too high acousto-optic lamp of condensing pressure and the too high acousto-optic lamp of water temperature.

Dress water temperature contact arm on right push rod shaft, the equipped the highest water temperature regulater in water temperature contact arm end, the highest water temperature regulater is by the too high contact of water temperature, L type contact arm and spring constitute.

Advantage of the present utility model and good effect be 1, when condensing pressure is too high, pressure in the tank body increases, compressing left bellows moves upward, promote left push rod and move upward, make the contact on the temperature difference adjustment disk touch spring sensing mechanism, this spring sensing mechanism and the too high contacting of condensing pressure, send working instruction signal or acousto-optic machine, remind the operator on duty to note, when generally adjusting the force value value of being above standard 0.01MPa, just send alarm signal; 2, because canonical base point is to be standard with the coolant temperature perceptron, when cooling water temperature raise, right push rod drove the spring sensing mechanism and raises, and owing to condensing pressure raises with cooling water temperature, thereby both can not touch mutually, can not report to the police.This has got rid of the reason that raises condensing pressure is raise because of water temperature simultaneously, makes the operator on duty take measures that accuracy and specific aim are more arranged; 3, when condensing pressure is too high, send sound and light alarm, more directly remind the operator on duty, overcome the subtle phenomenon of former Pressure gauge indicator rising; 4, the too high alarm lamp of water temperature is housed, when water temperature surpasses 30 ℃, sends sound and light alarm, provide the operator on duty to take measures; 5, the operator on duty in time solves condensing pressure and raises, and can make whole refrigeration system operation normal, removes low consumption of compressor, saves electric power, for the refrigeration system with multiple compressors, energy-conservationly is multiplied especially.
