Description
The utility model originally is about a kind of fluid conveying machine, specifically, is about a kind of hydraulically driven ram formula metering pump.
Background technique
Metering pump is a kind of device that can measure and control the conveying fluid flow, therefore is widely used in industries such as chemical industry, oil, military affairs, environmental protection, medicine, food, scientific research.Metering pump is made up of power end, transmission system and pump housing three parts, wherein can be divided into reducing gear, controlling mechanism, connecting rod three parts again for traditional transmission system, this shows that this kind transmission system is complicated.The subject matter that the metering pump of existing machinery transmission system exists: complex structure, rate of fault height, machinery driving efficiency is lower, power consumption is big, validity is low.
Summary of the invention
The utility model has overcome shortcoming of the prior art, and a kind of hydraulically driven ram formula metering pump is provided.
For realizing the purpose of this utility model, this adopts following technological scheme: fuel tank 1 is placed on the underframe 27; Level meter 2, air-strainer 3, thermorelay 4, level control relay 5, return filter 6, stop valve 7, oil suction filter 8 are contained in the fuel tank 1; Hydraulic valve bank 28 is contained in fuel tank 1 top; 15,3 adjustable one-way valves 16 of 14,3 solenoid directional control valves of one-way valve, pressure gauge 19, one-way valve 20, reduction valve 21, precursor overflow valve 22,23,2 pressure meter switches 24 of precursor overflow valve, pressure gauge 25 are housed in the hydraulic valve bank 28; Accumulator 26 is contained in the side of fuel tank 1, and accumulator 26 is connected with oil pipe; Oil cylinder 17, position limit switch 18 are installed on the underframe 27.
As preferably, it is that automation is controlled in realization because the characteristics of oil hydraulic circuit itself determine that each pump housing can be carried the medium of different flow that a plurality of pump housings are installed.Oil cylinder 17, solenoid directional control valve 15, fuel tank 1, manual variable displacement pump 13 are to connect into an oil hydraulic circuit by high-pressure rubber pipe, thereby finish the to-and-fro motion of oil cylinder plunger 29.Also be provided with pressure gauge 35 on cylinder sleeve 31 shells, so that whether check filler 32 damages.
Because adopt above-mentioned technological scheme, the utility model provides a kind of hydraulically driven ram formula metering pump to have such beneficial effect, has promptly simplified the metering pump structure, has improved mechanical efficiency, bearing capacity, precision height, the good energy saving property of metering pump greatly.
