Sanhe

Sanhe sorts its feeders by the kind of loom they serve. The SH2000 is the long-running family, sold in versions that differ in voltage and speed. The SHRP sits in the rapier and projectile group. SHJ units go on air-jet and water-jet looms, and the SHL and SHDM systems take over wider control duties on water-jet machines.

Start from the row that describes your mill. The right-hand column is the question to clear with Sanhe before any price is discussed. [1] [2] [3] [4]

Sanhe compares four SH2000 variants on a single page. Each one carries its own input voltage and top feed rate, from 180 V and 1,400 m/min on the SH2000A down to three-phase 45 V and 600 m/min on the SH2000C3. Two of them run on three-phase supply.

All four list automatic speed adjustment and S/Z yarn separation that can be set without steps. Two units can look alike from the outside and still differ inside. When you order a replacement, ask Sanhe to match the voltage, connector, controller and loom stop signal to the unit you are taking off. [2]

The SHRP is Sanhe's feeder for rapier weaving. A permanent-magnet motor drives it, metal sensing watches the yarn, and an outside knob picks one of four speed steps. Yarn separation adjusts by hand without tools, between 0 and 2.2 mm, and delivery tops out at 1,600 m/min. The housing is 330 × 151 × 190 mm and weighs 5.2 kg.

A coaxial tensioner at the output compensates tension when the loom runs at medium or low speed. Tell Sanhe when your yarn trouble shows up: in steady running, while the loom speeds up, or after a yarn change. Then ask which tensioning parts and settings it proposes for that moment, and check that the bracket suits your loom. [3]

Sanhe lists the SHJ-P among its feeders for air-jet and water-jet looms. It pairs pattern prediction with field-oriented motor control, uses photocell detection and has a spool body that adjusts from 108 to 135 mm in diameter. Separation runs from 0.7 to 2.2 mm. At 328 × 186 × 277 mm and 8.2 kg it is a larger unit than the SHRP.

Two speeds are printed. The SHJ-P feeds up to 2,000 m/min on its own and up to 2,400 m/min with pattern prediction switched on. If you plan around the higher number, the offer has to name the controller link and the pattern data the feeder needs from the loom.

Next to the feeders Sanhe sells the SHL three-in-one and SHDM four-in-one systems for water-jet looms. A single SHJ-P order is a part replacement. A main drive, a loom control cabinet or commissioning of the whole loom belongs to a separate control project, so ask for the two to be priced apart. [4] [1]

By Sanhe's own account the business began in 1996 and launched the SH2000 in 1998. The name Zhejiang Sanhe Textile Machinery dates from 2003. In 2015 an intelligent-technology company and other group firms were set up, and the current website trades as Zhejiang Sanhe Intelligent Tech Co., Ltd. The site's original directory listing carries the Textile Machinery name, so ask Sanhe which company will sign the contract and issue the invoice.

The product line grew in stages. SHJ-A appeared in 2000, SHJ-P in 2012 and the SHL water-jet control panel in 2013. Mills can therefore run feeders of several generations side by side. A clear photo of the label and controller tells Sanhe more about a unit than the loom's age does. [1]

Sanhe's company profile lists CNC machining, its own aluminium foundry, surface treatment, assembly, debugging and testing. Circuit boards are made in house on Yamaha mounting equipment, and Sanhe writes its own software and designs its own hardware. That makes it a feeder maker covering both the mechanical and the electronic side. Output volumes and the origin of bought-in parts are not published, so ask if your supplier checks need them.

The National Digital Library of Standards names Zhejiang Sanhe Textile Machinery Co., Ltd. as one of the drafting organizations of FZ/T 99007-2014, Weft accumulator. The standard was published on 6 May 2014 and took effect on 1 October 2014. It covers motor-driven feeders for shuttleless weaving and leaves out purely mechanical units. It speaks to Sanhe's role in the industry; a certificate for your own feeder is a separate document.

The website shows images of management-system and other certificates. Ask for current copies that show the holder, scope and expiry date. The about page also gives more than one total for utility-model patent records in different places, so request the patent numbers for the model you are buying. [1] [5]

Trial planning for weft feeders

A fast demonstration on easy yarn says little about the problem you want solved. Run the trial with your own yarn and keep the fault, the settings and the result in one record.

1. Pin down the unit you have

   Photograph the existing feeder label, controller and wiring. For an SH2000, name the version; for an SHJ-P, say how the loom controller would link to it.

2. Send the yarn and the fault

   Ship a representative yarn package with fibre, construction and count. Describe the fault you see, such as weft stops or uneven delivery, and the fabric being woven.

3. Watch the settings, then the speed

   Ask Sanhe to show the tensioner, separation and motor-speed choices it would use. Record them next to the fabric result before anyone turns up the speed.

4. Close out the offer

   Agree price, delivery time, spare parts and service for your country in the dated quotation.

Equipment model

SHRP

Sanhe's SHRP is a rapier-loom weft feeder with a permanent-magnet motor and metal sensor. It delivers yarn at up to 1600 m/min, sets separation from 0 to 2.2 mm and measures 330 × 151 × 190 mm at 5.2 kg. Yarn ranges are printed in Nm and dtex. For an offer, send the loom model, a yarn sample with count and unit, and a note of the feeding fault.
