Description
Technical field
The utility model relates to a kind of spinning pump test bed, relates in particular to a kind of the spinning pump test bed of chemical fibre spinning pump flow that be used to detect.
Background technique
Viscose spinning pump claims metering pump again, and it is the significant components of chemical fibre spinning machine.It is transported on the spinning nozzle equably to macromolecule polymer solution or melt accurate measurement and with it.The early stage axial-piston viscose spinning pump that uses all adopts the gear type viscose spinning pump now.According to a difference of the spin fluid of measuring and carrying, viscose spinning pump is divided into two types: one. melt spinning pump:, claim heat pump again for melt spinning usefulness.In the time of work, the viscose spinning pump transmission shaft drives driving shaft through joining shaft and rotates, and drives the working gear running by key, along with the rotation of gear, the spinning melt of suction chamber constantly are full of gear teeth paddy and are brought to delivery chamber.When the gear teeth of two gears were meshing with each other, the delivery chamber volume dwindled, and then melt was pressed to spinning nozzle.Two. solvent spinning pump: i.e. wet spinning and dry spinning pump.The serviceability temperature of this class pump is lower, according to the character of spinning solution, selects corrosion-resistant and wear-resisting made for use.The driving gear of melt-spun pump clockwise rotates, and the wet spinning pump then rotates counterclockwise.
Existing in the market be used to detect chemical fibre spinning pump flow spinning pump test bed generally not have and the measuring apparatus of test stand one, and the method for measurement of employing is a weight method usually both at home and abroad.The flow that is about to each viscose spinning pump outlet inserts measuring cup, with balance each measuring cup is weighed each gross weight and the net weight of measuring of record again.Every measurement one less important to measuring cup clean, weigh, record.Such metering method not only wastes time and energy, and the precision of metering is not high yet, existing spinning pump test bed equipment generally has only eight passages, can only test the flux test of 1-8 outlet, will change pump seat to 8 tests more than the outlet, finish test at twice, the auxiliary time of Xu Yaoing is long like this, efficient is low, tests that at twice test accuracy is also had a significant impact.
Along with the fast development of China's chemical fibre industry, the application of multiple exit spinning pump constantly enlarges, and is more and more higher to the flow accuracy requirement of metering pump.Therefore press for a kind of measuring accuracy height, time saving and energy saving spinning pump test bed on the market.
Summary of the invention
The utility model provides a kind of measuring accuracy height, time saving and energy saving spinning pump test bed, and tradition is spinning pump test bed not to have a defective that the metering equipment of one, measuring accuracy are low, waste time and energy to solve.
The spinning pump test bed fuel tank that comprises filter screen that comprises of the present utility model, the low pressure pump that has motor that links to each other with fuel tank by ball valve, low pressure pump links to each other with cooling system with relief valve by shutoff valve parallel with one another, and link to each other with fuel tank by cooling system, low pressure pump also links to each other with the pump seat of viscose spinning pump with ball valve by pressure gauge, pump seat links to each other with central processing unit (CPU) with motor by sensor, the ball valve of a plurality of outlets of pump seat by separately links to each other with separately gauge line, and link to each other with fuel tank with gauge line by solenoid valve, two sensors on the gauge line link to each other with central processing unit (CPU) by the communications cable, and gauge line also links to each other with fuel tank by output pipeline.
Further, two sensors are installed in the upper and lower of gauge line respectively.
Further, pump seat links to each other with ball valve with two relief valves parallel with one another by pressure gauge, solenoid valve and wherein a relief valve be cascaded.Purpose by design is by controlling the Kai Heguan of relief valve and relief valve, regulate the pressure of pump seat outlet, be i.e. the pressure of pressure gauge demonstration like this.
This spinning pump test bed working principle is as follows:
Solution in the fuel tank enters in the pipeline that has ball valve by filter screen, and by the motor in the low pressure pump solution is pressed onto on two output routes:
Wherein a route links to each other with cooling system with relief valve by shutoff valve parallel with one another from low pressure pump, shutoff valve and relief valve all are the parts of control channel switch, can be as required one of them of shutoff valve and relief valve be opened, can control the manometric pressure size that links to each other with the pump seat of viscose spinning pump, it is the size of pump seat inlet pressure, cooling system links to each other with fuel tank, cooling system is to be used for the temperature of the solution of control circle in entire equipment, make solution remain on certain temperature range, can effectively avoid the variation of the liquor capacity that the temperature difference brings, make the degree of accuracy of test platform improve.
Another route is to link to each other with the pump seat of viscose spinning pump with ball valve by pressure gauge from low pressure pump, so just the import of fuel tank and pump seat has been communicated with, pump seat links to each other with central processing unit (CPU) with motor by sensor, can be by central processing unit (CPU) according to the running of the signal control motor of sensor, can be according to the test needs, setting need be pressed into the volume of solution in the pump seat.
Each outlet of pump seat links to each other with the spinning pump test bed gauge line separately that carries by ball valve separately, and gauge line links to each other with fuel tank by output pipeline, and gauge line also links to each other with fuel tank with gauge line by solenoid valve.Like this, this solution just can circulate in spinning pump test bed, by the opening and close the conducting that can control solution on this branch road and end of control electromagnetic valve, two sensors links to each other with central processing unit (CPU) by the communications cable on the gauge line, and two sensors is installed in the upper and lower of gauge line respectively.Demarcate the volume of going up between the lower sensor with standard pump during beginning, with the volume data input central processing unit (CPU) of demarcating.When gauge line solution rose to lower sensor, central processing unit (CPU) began to receive the pulse signal that is sent by the branch fluted disc of installing on the drive motor.When solution rises to upper sensor, receive and stop and showing umber of pulse, revolution and revolution discharge capacity simultaneously signal conveys being arrived central processing unit (CPU).When solution in the gauge line surpassed the gauge line volume, excessive solution can be discharged to the fuel tank from the output pipeline of gauge line top.By time difference of sensor sensing in twos in more a plurality of gauge lines, can analyze the difference of each rate of discharge of pump seat, can analyze each outlet and whether meet standard.
The spinning pump test bed beneficial effect of the utility model is: the fast development of China's chemical fibre industry, the application of multiple exit spinning pump constantly enlarges, and is more and more higher to the flow accuracy requirement of metering pump.This spinning pump test bed accurate test that solves the multiple exit spinning pump has enlarged trial stretch, has improved the efficient of test significantly.
