Description
YHL32 4 column hydraulic press is used to transfer energy to achieve a variety of process according to PASCAL’s principle. It adopts liquid as working medium. and liquid as its working medium. Its main components are the main machine, the dynamic system and the hydraulic control system. In its oil cylinder, the piston lever is put into motion by high pressure oil which is transferred from the oil pump. In details, the oil is injected into integrated cartridge valves and then it is distributed to the oil cylinder through one-way valve and overflow valve. After all, this 4 column hydraulic press is an equipment transferring high-pressure hydraulic oil.
Application
This machine is widely used in pressing plastics, pulveralent products, metal products, etc. It can also be utilized in stretching thin metal sheets, bending work, correction for pressed products, etc.
Advantages
- YHL32 4 column hydraulic press has past ISO 9001:2008 certification. From finish machine, assembly, painting to leaving factory, whole processes are conducted under strict quality regulations. Besides, qualification rate of this machine is up to 98%.
- We possess a complete series of testing equipments for testing this machine, such as insulation resistance meter, hardness tester, grounding resistance tester, dielectric strength tester, sound level meter, digital temperature meter, level meter, etc.
- Our company guarantees permanent technical advisory services. The warranty period for this hydraulic press machine is one year.
- With simple structure, this 4 column hydraulic press is economical and practical. Besides, it is durable and convenient to operate.I
- It is equipped with independent electronic system in its actuating unit. With central button controlling panel, this machine can be controlled manually and semi-automatically.
- Its working pressure, pressing speed and sliding stroke are adjustable according to practical processing needs.
Attention
- Generally, only people with intimate knowledge of this 4 column hydraulic press can launch or operate it.
- If there is severe oil leakage or other malfunction when working, stop running and troubleshoot this machine. Only after problems are solved, can it be put into working.
- Sliding stroke should be controlled with the regulated scale (600 mm). Besides, it can not be overloaded during working.
- Ground leads should be tigntly connected, which ensures safety in operation.
- When the 4 column hydraulic press completes working, cut off the power supply and clean out the workshop.
- This machine should be out of power supply during maintenance. Besides, when maintenance is over, the wasted oil and related items, such as cloth containing oil, should be delivered to special recycling company.
Maintenance and Repair
- Every time it is switched on, it should be running for a while in empty load. But if it is in winter, this running time should be longer (more than 30 minutes). Only after this empty-load running, can this 4 column hydraulic press be put into normal work.
- If a new machine has beed used work for one week , its oil tank should be thoroughly cleaned. Then, its oil should be regularly changed and the oil tank cleaned out every six months (in facts, the exact time depends on the practical demands).
- No opeaning the oil tank cap or oil filler cap when the machine is running. Besides, after the pressure meter is adjusted, it should be turned off. It will damage the pressure meter if it is on for a longtime.
- The 4 column hydraulic press is forbidden to be used outdoors. Besides, rainproof measures should be taken.
Packaging, Transportation and Payment
It is delivered by ship and paid through T/T.
Working Principle
The hydraulic drive system is composed of power system, controlling unit, actuating unit, auxiliary equipments and working medium. To fulfill demands for high running speed, a pump or even several pumps are applied in the power system. Exactly speaking, if the oil pump is less than 2.5 Mp, a gear pump is used. If the oil pressure is larger but less than 6.3 Mp, the vane pump is better choice. And if the oil is even much higher but less than 32 Mp, the plunger pump is the best choice to this 4 column hydraulic press.
