Hydraulic motors have some distinguishing features. They are fluid power actuators with the capability to deliver either a linear or rotary motion. The type of motion delivered by hydraulic motors depends on the design. All hydraulic motors are capable of extracting fluid from a reservoir, cleaning it and returning it to the original reservoir.

Rephasing cylinders are two or more cylinders plumbed in series or parallel, with the bores and rods sized such that all rods extend and/or retract equally when flow is directed to the first, or last, cylinder within the system.

In "parallel" applications, the bore and rod sizes are always the same, and the cylinders are always used in pairs. The schematic shown on this page is for a "parallel" re-phasing cylinder application. Such circuits are typically used for the steering function on machines.

In "series" applications, the bore and rod sizes are typically different, and two or more cylinders may be used. In these applications, the bores and rods are sized such that all rods extend or retract equally when flow is applied to the first or last cylinder within the system.

This hydraulic synchronization of rod positions eliminates the need for a flow divider in the hydraulic system, or any type of mechanical connection between the cylinder rods to achieve synchronization. All double-acting Energy® cylinders can be modified to take advantage of these rephasing design benefits.

As you can see below, HGMPTH-III Brewhouse ( Copper & SS304), with the capacity of 10HL, is not only admited with reasonable design and fabrication, it also presents fashionable and modern appearance. More and more modern bars, testing brewery and brewing showing room perfer such Brewhouse with copper appearance. Any further, please call us or send email.


Based on the continuous development of distillation equipment in the first half of this year, HGM creates new design with unique performance - Aroma Distillation Equipment in July.

Actually, HGM intends to fabricate distillation equipment in series to meet various demands from different professions and enterprises.

We¡¯re proud that HGM is the first Chinese national manufacturer to engage in distillation equipment. With high starting point, HGM distillation equipment are completely developed and manufactured according to the highest level standards worldwide and has obtained many intellectual property rights right now.

Solar street lights are not new products. Usually, the system contains street lamps, solar panel, solar controller, batteries, arm, pole, wires and so on.

You may find some projects in your city. They can save all electricity cost and resources. It looks like great. You may think we should use solar street lamps everywhere. However, why are they not so popular?

1. Why not so popular now

The main reason is cost. When the power consumption of street lamps is 60 Watt, it needs 150 - 170 Watt solar panel and 2 units 80 Ah batteries. The cost is near USD 1, 000. If the power consumption is higher, such as 150 Watt, the cost will be a little amazing. Many countries can not accept the price.
However, as traditional HPS street lights, the power consumption is usually 60W, 80W, 150W, 250W or 400W. So, the cost is high in most of cases. Many countries can not accept the cost.

2. LED technology

In the past two years, LED street lights become more and more popular. They use LED (Light Emitting Diode) as light sources. Comparing with traditional HPS lamps, LED lamps can save 50%-70% energy. For example, 30W, 60W, 110W and 160W LED lamps can replace 80W, 150W, 250W and 400W HPS lamps.

3. Advantages of LED Street Lights

Main advantages are as follow

1). Lower power consumption

2). Higher power efficacy - LED street lights exceed mercury vapor's 31 lm/W. You can find higher efficacy measurement from for high pressure sodium lamps. It is just misleading because It includes wasted light that in turn wastes energy. In the market, many power efficacy of LED street lights can reach up to 80lm/w.

3). More Lux Per Watt - more than double that of a mercury vapor street light. The equivalent measurement for high pressure sodium lamps is skewed by hot spots that bump up the lux rating but cause undesirable visibility, safety and glare problems.

4) Longer lifetime (50,000 hours)

4. Why solar LED street lights will be very popular

Because LED lamps are energy saving, it can reduce cost of solar kits. When the cost is low, many countries can accept them.

For example, 60W solar LED street lamps can replace traditional 150W HPS street lamps. It will save all electricity. If you calculate ROI, you will find it's over 30% in two years. Why not accept?

Besides, LED is in semiconductor industry. The efficiency increases quickly. The cost of solar panel will be lower in the future.

So, LED lamps with solar kits are perfect combination. They will be very popular in the future 3 years.
